We are a small, funded product team taking a live iOS and Android app (React Native) into its most important release. The app is moving from a manual tool to an intelligent, automated daily companion. We are hiring one senior developer to own both the front-end experience and the back-end intelligence layer, and to help us make the key architecture decisions for what comes next. Full product details are shared under NDA. This post is about the bar we need you to clear, so read the application instructions carefully. The One Thing That Matters Most You have personally built and shipped cross-platform mobile apps that real users have in their hands today. Not prototypes, not tutorials, not apps that stalled before launch. We want to see them, use them, and hear exactly what you built. Everything below matters, but nothing matters more than proof that you have taken a mobile app all the way to the App Store and Google Play and kept it running. What You Will Own Front end A polished, animated experience: onboarding flows, sequenced screens, and a completion moment that has to feel premium. We care about craft and detail, not just functional screens. Back end Data modeling, serverless functions, a per-user scheduled notification engine, third-party AI API integration, subscription entitlement logic, and a time-series scoring system. Our current stack runs on Firebase, so you will work in it from day one, but part of your job is to tell us where it should go next. Your first deliverables In your first 1-2 weeks, before heavy building starts, you will: Review our functional spec (FSD) and write the technical spec (TSD) for how you will build it Give us your own build estimate and milestone plan against the October 31, 2026 target. Deliver a written backend recommendation: stay on our current stack, extend it, or migrate. For the backend call, weigh Firebase/Firestore, Postgres (for example Supabase), and other options against our real needs: 10,000+ active users, AI API integration, offline-first sync, reliable push at scale, velocity, and cost. We want an objective read from someone who has shipped on more than one backend, not someone married to a single tool. What You Must Have 3+ years building React Native apps that are live in production on both iOS and Android. Shipped and maintained, not just started. Strong full-stack backend fundamentals: serverless/cloud functions, data modeling, auth, security rules or access control, and API design. Hands-on experience with both a NoSQL database (for example Firestore) and a relational database (Postgres or similar). You should be able to reason about the trade-offs, because you will be advising us on exactly that. Production experience integrating a third-party AI API (Claude, OpenAI, or comparable), including handling latency, cost, and structured output. Proficient in TypeScript. Our codebase is TypeScript. RevenueCat for subscription entitlement management. It is already integrated in our codebase. Push notification infrastructure and scheduled/triggered server logic that runs reliably per user. Clear written English and comfort working async-first over Slack, with GitHub-based code review. Strong Advantage (Not Required) If you have shipped these before, tell us. If not, we expect a strong engineer to pick them up quickly. Firebase at real scale in production: Firestore schema design, Cloud Functions with complex triggers, FCM, and Firebase Auth. UX/UI craft: polished animation work such as SVG stroke animation, radial gradients, and staggered/sequenced motion. Device-native speech-to-text on iOS and Android. Anthropic Claude API specifics: prompt caching, system-prompt engineering, structured output. Experience scaling a consumer or wellness/subscription app to 10,000+ active users. Engagement Time commitment: we expect roughly 20+ hours per week, sustained. This is a real ongoing engagement, not a few hours here and there. Timeline: our v3 release targets October 2026. Expect focused, steady delivery between now and then, with the backend recommendation done in your first few weeks so we can lock the architecture early. Scope: substantial multi-month build with strong potential to continue into v3+ if it is a good fit. We would rather find one reliable partner for the long haul than churn through contractors. Tooling: GitHub, Slack for daily communication, TestFlight for iOS builds. Contract, hourly or fixed-price per sprint. Your preference. Tell us your rate and preferred structure. All builds, schema changes, and deployments are reviewed before release. We commit to a 48-hour feedback turnaround. How to Apply — Read Carefully You must submit a portfolio website or a link to your work before any screening call. Applications without a portfolio link will not be reviewed and will not receive a call. To be considered, include all of the following: A portfolio or work link (required, no exceptions). Applications without one will not be reviewed. One shipped mobile app you are proud of, live on iOS and/or Android, with a store link or video. Tell us specifically what you built. One backend system or serverless function you built. Describe the scale, the data model, and the hardest problem you solved. One example of UI craft or complex interaction, with the visible result (link, video, or GIF). Your one-paragraph read on the backend question: given the needs above, would you stay, extend, or migrate, and why? A confident “it depends, here is how I would decide” is a great answer. A brief note on how you approach scoping and estimating a build like this. We do not expect a number before you have seen the spec, but we want to see how you think about it. Your rate, preferred engagement structure, and realistic start date. How many hours per week you can realistically commit, sustained, between now and an October 31, 2026 v3 target. Be honest. We would rather know your real capacity up front. We respond to every complete application. We are looking for a developer who takes their craft seriously.

Duties and Responsibilities: - Primarily work on backend systems such as API servers written in Go (Golang) and are backed by a variety of SQL and NoSQL databases. - Ability to work on software development kits in a variety of languages (e.g. Python, R, Typescript) to assist code consumption of backend systems. - Feature development will include tasks like: o Ingesting data from third party systems and loading them into our in-house data stores o Implementing API handlers to serve in-house data out to internal systems and users o Creating web apps to visualize the data in meaningful ways for the front office to manage in-season operations o Creating web apps to monitor and manage the data flows for front office admins to control

About us We're a consulting firm building agentic AI solutions for clients in law, healthcare, education, retail, commerce, and regulatory consulting. Our work sits at the intersection of LLM orchestration, workflow automation, and compliance-sensitive deployment. We're not building toy demos. We ship production systems for organisations where reliability, auditability, and regulatory posture actually matter. The role We're hiring a lead full-stack developer to take technical ownership of our agentic automation builds and grow a small delivery team. You'll be the person clients trust to architect the solution, and the person our team look to for direction. You'll be doing a mix of: Designing end-to-end agentic workflows (planning, tool use, memory, retrieval, human-in-the-loop checkpoints) Building and shipping client solutions across the stack — backend orchestration, integrations, frontends, infrastructure Leading and reviewing the work of other developers as we scale Working directly with clients to translate ambiguous business problems into reliable automation Setting our technical standards: evals, observability, prompt and tool governance, deployment patterns Required experience 5+ years full-stack development, with strong backend fundamentals (Python and/or TypeScript) Demonstrable production experience with agentic systems — not just chatbots. We want to see agents that plan, use tools, recover from errors, and operate over real workflows Hands-on with at least one major agent framework or orchestration approach (LangGraph, CrewAI, custom orchestration, Claude/OpenAI tool use, MCP, etc.) Experience integrating with enterprise systems via APIs and webhooks (CRM, email, document stores, internal databases) Cloud deployment experience (AWS preferred; Azure or GCP acceptable) Frontend competence in React or similar — you don't need to be a designer, but you should be able to ship a clean client-facing UI Strong written English and clear communication. You'll be talking to non-technical stakeholders regularly Nice to have Experience working in or with regulated industries (healthcare, legal, financial services, education) Familiarity with RAG pipelines, vector stores, and retrieval evaluation Exposure to compliance frameworks (SOC 2, ISO 27001, GDPR, sector-specific regs) Prior tech lead or solo founder experience Comfort with infrastructure-as-code (Terraform, CDK) Comfortable working with and reviewing the output from agentic coding systems to speed up development (Codex, Claude Code etc.) What we're offering Long-term engagement, starting with a paid trial project Competitive hourly rate (share your expectation in your application) Real ownership and the opportunity to shape how we deliver Interesting, varied work across sectors — no two builds the same How to apply In your proposal, please include: A short summary of an agentic system you've shipped to production. What did it do, what was the architecture, and what broke that you had to fix? Your stack of choice for a new agentic build today, and why Your hourly rate and approximate weekly availability A link to code or a portfolio if you have one

We’re seeking a senior full-stack engineer to help build and improve a consumer FinTech product. You’ll work across web and mobile platforms, support product development, and help shape technical decisions. The role includes collaborating with product and engineering teams, delivering reliable features, and contributing to a growing product. We’re looking for someone with strong technical judgment, ownership, and the ability to work independently in a fast-paced environment. Affordia Finance is hiring a senior full-stack engineer to take ownership of our household finance application and carry it through MVP completion, compliance vetting, customer testing, and commercial launch. This is the primary engineering seat on the product — not a task-based gig. We are looking for one accountable owner who will still be with us at launch. About Affordia Finance Affordia is building a household finance application that helps families see, understand, and reduce the real cost of running their household. We connect a household's accounts through Plaid, do the arithmetic families cannot easily do themselves, benchmark their spending against comparable households, and report it back in plain language. Our first customer cohort is households in or near retirement, but the product is designed to serve families across life stages. The company is founder-led, self-funded, and past the concept stage: we have a working application, defined pricing, completed customer research, and a fixed launch calendar. What You Will Own You are taking over an existing React/TypeScript application from a departing contractor. Your first job is to assess what exists, take clean ownership of it, and re-architect it into a maintainable, testable codebase that can carry a paying subscriber base. From there you build. • Codebase ownership. Assume full ownership of the front-end and back-end codebase, including refactoring the current application into a modular, production-grade architecture. • Account aggregation. Build and harden our read-only Plaid integration — institution coverage, item health, re-authentication flows, transaction normalization, categorization accuracy, and graceful handling of partial or missing data. • Mobile delivery. Extend the product from responsive web to a genuine mobile experience. We are open to React Native, a well-built PWA, or another approach you can defend on cost, speed, and App Store risk. • Security and data handling. Implement authentication, encryption in transit and at rest, secrets management, least-privilege data access, and audit logging appropriate to a consumer financial application. • Release infrastructure. Stand up CI/CD, automated testing, error monitoring, and analytics so we can run customer testing cycles and act on what we learn. • Documentation for review. Support compliance review by producing clear technical documentation of data flows, third-party dependencies, storage, and retention. • Commercial readiness. Prepare the application for paid subscriptions across our tiered plans, including billing integration, entitlement logic, and account lifecycle. Timeline and Milestones Work is scoped and paid as fixed-fee milestones. Each milestone has written acceptance criteria agreed before work begins.

If not, this role will be very uncomfortable. **THIS IS A FT, HOURLY ROLE. PROVIDE YOUR REQUESTED HOURLY RATE IN PROPOSAL**

I’m looking for an experienced full-stack developer to help improve an existing React Native mobile app and build a modern web platform for the same product. The mobile app is already live on the App Store, and I’m looking to modernize the UI/UX, improve the overall user experience, and add new features over time. Alongside the app, I need a responsive website where users can learn about the platform, create accounts, subscribe, and manage their information through a secure dashboard. The platform is focused on amateur basketball leagues and will continue to grow, so I’m looking for someone who can build with scalability and maintainability in mind rather than simply delivering a one-time project. I’m looking for a developer who: * Has strong experience with React Native and modern web development * Is comfortable working with Firebase and subscription-based applications * Writes clean, scalable, well-documented code * Uses modern AI development tools (such as Cursor, Claude, GitHub Copilot, etc.) to work efficiently * Can communicate clearly and contribute to technical decisions This has the potential to become a long-term working relationship as the platform continues to expand. My goal is to find someone who can initially build the next phase of the product and potentially continue as the technical lead as we grow.
