Overview I have a Next.js website with a newsletter signup form that currently submits directly from the browser to HubSpot's Forms v3 endpoint. I want to add a lightweight LLM-based spam filter that inspects each submission *before* it reaches HubSpot, and silently rejects (or flags) anything that looks like spam/bot/junk input. Current setup - Framework: Next.js (App Router, TypeScript, React client component) - The form component (`NewsletterForm.tsx`) POSTs directly to `https://api.hsforms.com/submissions/v3/integration/submit/[portalId]/[formGuid]` - Fields collected: `firstname`, `lastname` (optional), `jobtitle`, `email` - Portal ID and Form GUID are public form identifiers (no secrets today) What I want you to build 1. Create a server-side API route in the Next.js app (e.g. `app/api/subscribe/route.ts`) that: - Receives the form fields from the client - Runs an LLM spam/quality check (e.g. OpenAI or similar) to classify the submission as legit vs. spam — checking for gibberish names, fake/disposable emails, nonsense job titles, injection attempts, etc. - If legit → forwards the submission to HubSpot (server-side) - If spam → rejects gracefully with a generic message (no HubSpot write) 2. Update the existing `NewsletterForm.tsx` to POST to the new internal API route instead of calling HubSpot directly. 3. Keep the LLM API key server-side only (use an environment variable — never expose it to the client). 4. Preserve the existing UX: loading / success / error states should still work. Deliverables - Working API route with the LLM spam check + HubSpot forwarding - Updated form component - Brief note on which env vars to set (`OPENAI_API_KEY`, etc.) and how to configure them - Clean, typed TypeScript that matches the existing code style Nice to have (optional) - Basic rate limiting / honeypot field as a cheap first line of defense before the LLM call - Configurable spam threshold or a logged "reason" when something is rejected Requirements to apply - Strong Next.js App Router + TypeScript experience - Experience calling an LLM API (OpenAI or equivalent) from a server route - Familiarity with HubSpot Forms API is a plus To apply, please briefly answer: 1. Which LLM/provider would you use and roughly what would it cost per submission? 2. How would you handle the case where the LLM API is slow or down — do you fail open (let it through) or fail closed (block it)? 3. Have you integrated with HubSpot Forms before? (yes/no is fine)

The Opportunity We are not just building a mobile app; we are building the future of how mobile applications are architected, tested, and deployed. We are seeking a Senior React Native Engineer who lives at the intersection of mobile development and generative AI. In this role, you will be the bridge between complex product requirements and pixel-perfect, performant mobile experiences. You will leverage Expo to streamline the development lifecycle across iOS and Android while championing an AI-First engineering culture. You will be expected to treat LLMs (specifically Claude) not as a "chatbot," but as a force multiplier for architecture, unit testing, and spec generation. What You’ll Do (The Core Responsibilities) 1. Mobile Architecture & Development (The Craft) - Architect & Build: Design, develop, and maintain high-performance, scalable mobile applications using React Native and the Expo framework (EAS Build, Updates, and Modules). - Native Integrations: Write and maintain custom Native Modules (Swift/Kotlin) when the React Native ecosystem falls short, ensuring seamless performance on both iOS and Android. - Performance Tuning: Profile and optimize app performance focusing on startup time, rendering (Reanimated), and memory management to ensure a 60fps experience across devices. - CI/CD: Own the deployment pipeline using EAS, managing internal distribution, TestFlight, and Google Play Store submissions. 2. The AI-First Mandate (The "Secret Sauce") - LLM Integration: Design the architecture for integrating LLM APIs (Anthropic Claude, OpenAI) directly into the client-side application, handling streaming responses, function calling, and token management. - Code Generation & Refactoring: Utilize AI agents to generate boilerplate, complex Redux/Recoil slices, and Zod validation schemas. - Prompt Engineering: Lead the team in writing system prompts that are deterministic and version-controlled, moving beyond "trial and error" to rigorous prompt testing. - Spec-Driven Development: Implement a "Spec-First" approach. You will be expected to convert high-level design specs (Figma/PRD) into structured JSON schemas that can be consumed by AI to generate UI components and state logic. - Tooling & Plugins: Develop internal VS Code plugins or CLI tools that scaffold new features using AI, standardizing our codebase structure. 3. Collaboration & Standards - Code Reviews: Conduct thorough code reviews with a focus on type safety (TypeScript), maintainability, and adherence to our coding standards. - Mentorship: Guide junior engineers in utilizing AI tools effectively, moving them from "copy-paste" engineering to "architectural" engineering. - Cross-Functional: Work closely with Product and Design to translate business requirements into technical solutions, using AI to rapidly prototype iterations during sprint planning. The Technical Stack Core: React Native (v0.72+), TypeScript, Expo SDK 50+. State: Zustand / Redux Toolkit / Jotai. Navigation: React Navigation 6 (Native Stack). Styling: TailwindCSS (via NativeWind) or StyleSheets with a strong emphasis on Design Tokens. APIs: GraphQL (Apollo) / REST (React Query). Infrastructure: EAS (Build, Submit, Update), Sentry, Amplitude. Testing: Jest, React Native Testing Library, Maestro (for E2E). AI: Claude API, LangChain (or similar orchestration frameworks). Must-Have Qualifications Experience: 5+ years of software engineering experience, with 3+ years dedicated exclusively to React Native production applications.

Dual Platform: Proven experience publishing and maintaining apps on both the Apple App Store and Google Play Store, including handling App Store Connect/Play Console intricacies. TypeScript Mastery: You treat the TypeScript compiler as your best friend. You write complex generics and conditional types to ensure type safety across API boundaries. The AI Proficiency Requirement (Non-Negotiable) We are looking for a "10x" engineer who leverages AI effectively. You must demonstrate: Articulation: Ability to articulate how to use AI Plugins (e.g., Claude, Cursor AI, Continue.dev) to iterate on codebases faster. You know when to trust the AI and when to override it. Skills Architecture: Experience defining reusable "Skills" or "Prompts" within the engineering team that standardize how we generate components, write tests, and document code. Spec-Driven Development: You have experience writing spec.md or plan.md files that an LLM consumes to generate the initial scaffolding of a feature before you refine it. Semantic Search: Experience using vector databases or embedding search to allow AI to accurately query our codebase to avoid hallucination during generation Expo EAS Deployment Requirements EAS Build Ownership: You have configured and maintained eas.json build profiles (development, preview, production) across iOS and Android, including credential management, provisioning profiles, keystores, and custom build resource classes. EAS Submit: Hands-on experience automating store submissions to App Store Connect and Google Play via EAS Submit, including service account setup, App Store Connect API keys, and phased rollouts. EAS Update (OTA): You have shipped over-the-air updates in production — branch and channel strategy, runtime version policies, rollback procedures, and knowing which changes require a full binary release. Config Plugins: Ability to write and debug custom Expo config plugins to inject native configuration without ejecting from the managed workflow. Release Automation: Experience wiring EAS into CI (GitHub Actions or similar) for automated builds on merge, versioning and build-number strategy, and gated promotion from internal distribution to TestFlight to production. Release Hygiene: Familiarity with source maps and release tagging for Sentry, plus monitoring update adoption rates after each release. Figma Design Integration Design-to-Code Workflow: Experience translating Figma design files directly into React Native components, including auto-layout, variants, and component properties into a matching design-token and component structure. Design Tokens & Dev Mode: Proficiency using Figma Dev Mode (or plugins such as Figma Tokens) to extract and sync colors, spacing, and typography tokens into the app's design system, keeping design and code in lockstep as Figma files evolve. Design QA: Ability to review implemented screens against Figma specs for pixel-level fidelity across iOS and Android, flagging platform-specific rendering differences. AI-Assisted Handoff: Experience feeding Figma specs (via API or exported JSON) into AI tooling to auto-generate initial component scaffolding, consistent with this role's Spec-Driven Development mandate. TestFlight & Google Play Internal Testing TestFlight Management: Experience managing TestFlight builds end-to-end — internal and external tester groups, build expiration windows, beta App Review submissions, and collecting/triaging tester crash logs and feedback. Google Play Testing Tracks: Equivalent hands-on experience with Google Play's internal testing, closed testing, and open testing tracks, including managing tester email lists/opt-in links and promoting a build between tracks. Staged & Phased Rollouts: Experience configuring Play Console staged rollouts and App Store Connect phased releases, monitoring crash-free rate and adoption metrics before widening exposure, and halting a rollout when needed. Pre-Submission Compliance: Familiarity with App Store Review Guidelines and Google Play policy requirements (e.g., Data Safety section, permissions justification) sufficient to avoid common rejection reasons. Nice-to-Have Skills Backend (Python FastAPI): Strong experience with Python and FastAPI is highly desirable. You will be expected to review backend PRs and occasionally contribute to the API layer when the mobile app requires a custom endpoint. (We love engineers who are full-stack).

Project: AI Integration for Existing Web Application Engagement type: Contract / project-based (small agency or independent consultant) Location: United States-based preferred Budget: Small business budget — please quote fixed-price or capped hourly for defined scope Start: Flexible, pilot sprint preferred before full engagement About the project We run a web application built on: • Frontend: React • Backend: Node.js and Java • Database: PostgreSQL • Infrastructure: AWS We're looking to integrate AI into this existing system to reduce manual data updates and add intelligent features — automation, smart search/recommendations, and reduced manual maintenance overhead. We are a small company with a limited budget and are looking for a small, senior-led team or independent consultant who can deliver production-quality work without enterprise-agency overhead or pricing. What we need help with • Auditing our current architecture and recommending where AI adds the most value with the least complexity • Setting up vector search / retrieval (e.g. pgvector in PostgreSQL) for semantic search or RAG use cases • Integrating AWS AI services (Bedrock and/or SageMaker) into our Node.js/Java backend • Building automation (e.g. AWS EventBridge + Lambda) so routine data updates happen automatically instead of manually • Adding AI-powered features to the React frontend (e.g. smart suggestions, summarization, natural-language search) • Ensuring the solution is cost-aware — we need ongoing AWS/AI usage costs kept lean, not just the build cost Ideal candidate / team • Small shop (roughly 2–15 people) or independent senior consultant — not a large offshore agency • Demonstrable senior-level experience: has personally built and shipped production systems with this stack, not just managed a team that did • Hands-on experience integrating LLMs/AI services into an existing production application (not just greenfield AI demos) • Comfortable working with a small business budget and scoping work in phases rather than one large fixed engagement • Clear, direct communicator — able to explain technical tradeoffs in plain language • U.S.-based (or U.S. business entity) preferred for time zone alignment and contracting simplicity What we'll provide • Access to existing codebase, architecture docs, and AWS environment (under NDA) • A single point of contact for requirements and feedback • Clear priorities on which features matter most, once we've discussed scope Engagement structure we're proposing 1. Discovery / architecture review (paid, fixed fee) — assess our system and propose a phased AI integration plan with rough cost estimates (build + ongoing AWS/AI usage) 2. Pilot sprint (1–2 weeks, fixed scope) — implement one narrow AI feature end-to-end to evaluate fit before committing further 3. Phased build-out — based on pilot results, scope remaining work in defined phases How to apply / respond Please share: • 2–3 past projects with a similar stack (Postgres + AWS + AI/LLM integration), ideally with what you built and the outcome • Your team size and who would actually be working on this project • Your typical pricing structure (hourly, fixed-fee, retainer) and rough budget range you work within • Availability and expected timeline for a discovery call We're prioritizing fit and communication over lowest price — we'd rather pay fairly for a small team that gets it right than the cheapest bid.

Title Front-End Developer to Maintain & Improve a Static Promotional-Products Website (HTML/CSS/JS + Netlify) Overview We run a boutique promotional-products agency (BespokePromos). Our website is already built and live — a fast, hand-coded static site (plain HTML, CSS, and vanilla JavaScript) hosted on Netlify and auto-deploying from GitHub. Product prices sync live from a Google Sheet, and quote requests come in through Netlify Forms. We're looking for a reliable front-end developer to take over ongoing maintenance and knock out a short list of improvements. This is not a rebuild — the site works well and we want to keep the current simple stack. If your instinct is to rewrite it in React or a big framework, we're not a fit. Our tech stack (please only apply if you're comfortable with all of this) HTML, CSS, and vanilla JavaScript (no framework — no React/Vue/Angular) Netlify (deploys, Netlify Forms, DNS) GitHub (the site auto-deploys from the main branch) Google Apps Script (a small script syncs prices from a Google Sheet to the site) Responsive/mobile CSS and basic on-page SEO First tasks (roughly in priority order) Point our domain bespokepromos.com (registered at GoDaddy) at the Netlify site and get HTTPS working. Set up Google Search Console (submit sitemap), Google Analytics, and a Google Business Profile. Add a testimonials / social-proof section (we'll supply the real client quotes). General fixes and small enhancements as they come up. (There's more we'd like to do over time — this is a potential ongoing relationship, not a one-off.) What we'll provide Access to the GitHub repo, Netlify account, the Google Sheet, and the GoDaddy domain. A written technical handoff doc explaining exactly how the site works (architecture, the price-sync, the quote form, all pages) — so you can be productive immediately. To apply, please tell us A couple of similar small-business / e-commerce-style sites you've built or maintained (links). Your experience with Netlify + GitHub deploys and, if any, Google Apps Script. Your hourly rate and typical availability. Briefly: after reading our handoff doc, how would you approach the domain cutover? (A short answer here tells us you actually read it.) How we'll work We'd like to start with one small paid task (the domain cutover or the testimonials section) before committing to more. Prefer hourly with clear updates. Clear, plain-English communication matters — we're not technical on our end. Ideal candidate Top Rated with strong Job Success Score (90%+) and real reviews. Comfortable working inside an existing, simple codebase without over-engineering it. Good at explaining things to a non-technical client.
