New website needed for a B2B outsourcing company serving the US mortgage and financial services industry. The site has two main service divisions, each with their own section architecture, operating under one parent brand. We have a clear site structure, page-level content direction, and brand positioning already worked out. We need a developer who can take a design direction and build a clean, fast, production-ready site. We are open to AI-assisted development (v0, Cursor, Claude Code, etc.) and prefer candidates who work this way. Speed and quality both matter.

Summary: We are building Sphere Inc., an AI-powered SaaS platform focused on the real estate industry. The product is currently in the MVP stage, and we are looking for a strong full-stack developer who can help us build, refine, and launch the first working version. The platform is designed to help real estate businesses automate daily operations, improve decision-making, and use AI agents to support workflows such as property management, lead handling, deal analysis, document processing, reporting, and business automation. This is not a basic website project. We are building a real SaaS product with a modern frontend, reliable backend, AI-powered workflows, and scalable AWS infrastructure. Current Project Status: The product vision and core direction are already defined. We are currently shaping the MVP workflows, user experience, and technical structure. At this stage, our main need is execution. We need someone who can help turn the concept into a working MVP that can be tested with real users. Some workflows are still being refined, so we are looking for a developer who can contribute both technically and practically — not just write code from fixed tickets. Current Progress & Bottlenecks We have a clear direction, but need support with - Structuring the MVP architecture - Building the frontend and backend features - Designing practical AI agent workflows - Connecting AI features with real estate data and user actions - Setting up AWS infrastructure for development and deployment - Creating a clean experience for non-technical business users - Prioritizing the most important MVP features The main bottleneck right now is moving from concept/prototype stage into a stable, usable product. We are looking for someone who has experience with - Building SaaS products from MVP to production - Full-stack development with Python, Node.js, JavaScript, and TypeScript - Frontend development using React, Next.js, or similar frameworks - Backend APIs, database design, authentication, and user roles - AI agents, LLM integrations, workflow automation, or RAG - AWS deployment, storage, monitoring, and security - Real estate platforms, CRMs, property data, document workflows, reporting, or automation tools - Writing clean, maintainable, and scalable code Tech Stack: Python, Node.js, JavaScript/TypeScript, React or Next.js, PostgreSQL, AWS, REST APIs, and AI/LLM tools such as OpenAI, Anthropic, AWS Bedrock, LangChain, LangGraph, or similar frameworks. Responsibilities: - Build frontend and backend features for the MVP - Design and implement AI-powered workflows and agent features - Connect APIs, databases, authentication, and user roles - Set up or improve AWS infrastructure - Help prioritize features and identify technical risks - Communicate progress clearly and regularly Some Knowledge That Is a Plus: - Real estate CRM, property management, brokerage, acquisitions, or leasing platform experience - AWS Bedrock, LangChain, LangGraph, or vector databases - Multi-tenant SaaS architecture - Stripe or subscription billing - DevOps, Docker, CI/CD, and testing - Analytics dashboards, reporting tools, or document automation The ideal candidate is a reliable full-stack developer who can work independently, understand the product vision, ask smart questions, and help us make practical technical decisions during the MVP stage. We need someone who is comfortable in an early-stage environment and can help turn a clear idea into a working SaaS product for real estate users. Please include: 1. Your GitHub, portfolio, or examples of previous work 2. A brief description of your related SaaS experience 3. Examples of AI agent, AI automation, or LLM-powered products you have built 4. Your AWS experience 5. Any real estate platform, CRM, data, or automation experience 6.

Full-stack developer (Node.js/TypeScript, React) with cloud/DevOps experience, and comfortable with PostgreSQL, S3-compatible storage, and Google Cloud service accounts. This is to support solid mobile app built for dual platforms, with a full ML comparison pipeline, and the supporting infrastructure. Initial Task will be an infrastructure migration (DevOps). Second task will be several front end and backend app updates.

We are seeking a Mid to Senior-level Fullstack Developer (3–5 years of experience) to not only maintain and expand our platform (Next.js frontend + Django backend) but also guide us in fully integrating AI-powered coding assistance across the full stack. The frontend is already set up for AI-assisted editing (e.g. Cursor), and we want to evolve our backend similarly. The ideal candidate will help us transition the entire development environment, so both we and the developer can leverage state-of-the-art AI coding tools. Beyond coding, you’ll act as a mentor, helping us better understand the backend’s architecture and workflows while integrating AI-driven development tools into our process. You’ll have a key role in making our stack both stable and future-ready, with AI-assisted flexibility. The Context Our frontend was recently ported to Next.js in an ad-hoc manner, leaving certain sections in need of refactoring and stabilization. We have committed to keeping our backend in Django to leverage its robust processing capabilities. You will be the point person for bridging these two environments. Key Responsibilities -Maintenance & Stability: Perform routine maintenance and optimization across the full stack. -Bug Fixing: Identify and resolve issues within the existing Next.js frontend and Django backend. -System Reliability: Provide technical support and troubleshooting during system downtime. -Feature Implementation: Build and deploy new features, ensuring seamless integration between the AI pipeline and the user interface. Required Technical Profile -3–5 years of professional fullstack experience. -Frontend: Proficiency in Next.js and React; experience cleaning up/refactoring "messy" or legacy codebases is a plus. -Backend: Strong experience with Django (Python), specifically working with complex data pipelines or API integrations. -Mindset: A pragmatic approach to coding—balancing the need for new features with the necessity of technical debt reduction.

⚠️ CRITICAL NOTICE BEFORE APPLYING: The budget and milestones for this MVP stabilization phase are fixed at $500 and are completely non-negotiable. We are looking for a focused, elite developer—not a corporate agency looking to over-scope or up-sell us. Payment is strictly tied to real-world performance metrics. Milestone 1 requires a live mobile stopwatch test showing sub-1-second cache loading on repeat lookups. We measure deliverables with a stopwatch, not excuses. If you do not have deep experience with high-speed backend architecture and caching models, please do not apply. 🚀 The Long-Term Equity & Full-Time Vision: While this initial stabilization phase is a compact $500 MVP project, we are actively scouting for our long-term technical partner. The engineer who successfully executes this phase and cracks our speed bottleneck will have the first right of refusal for a permanent, full-time position as our Lead Developer. You will spearhead the architecture for the entire upcoming Reseller Bro Ecosystem, which includes building out our dedicated social media features, rolling out full business-to-business (B2B) cross-platform inventory management tools, and leading our upcoming wearable AR glasses workflow ("Bro Lens"). www.resellerbro.com Project Overview: Please note: This application is approximately 80% complete. The front-end user interface, layout screens, and navigation are already fully built out. We are not asking you to build an app from scratch. We need an expert developer to step in and handle the final 20% of the project: cleaning up our database cache to hit our performance targets, implementing a tier-condition formula, handling minor UI adjustments, and adding high-energy audio/vibration triggers. IReseller Bro is a powerful mobile utility application designed for on-the-go resellers to instantly analyze product values, get a FLIP/SKIP verdict, and SAVE to a digital cart in seconds. We are anchoring our backend data pipeline to a high-speed eBay API model that automatically calculates smart market estimates for other secondary platforms. The Core Tasks & Milestone Payment Structure: 🔹 Milestone 1: Sub-1-Second Centralized Caching ($100 Escrow) The Issue: The previous build incorrectly forced live AI image recognition to run on every single scan, causing a painful 7–8 second delay even on repeat lookups. The Fix: You must implement a proper, high-speed database caching layer. The first initial scan of a brand-new item can take up to 7 seconds to run the AI workflow and fetch external marketplace data. However, on any repeat scan by any user, the app must bypass the AI image recognition entirely, read a cached unique identifier, and pull the results from the database instantly in under 1 second. 🔹 Milestone 2: Data Engine & Percentage-Based Estimation Matrix ($200 Escrow) The Fix: Connect the backend cleanly with the official eBay Browse API using our developer keys. Target Marketplaces: The app displays valuation metrics for four core platforms: eBay, Depop, Grailed, and Poshmark. Condition Matrix & Platform Estimation Formula: Build an automated mapping matrix. The app will pull raw condition data from the eBay API, group it cleanly into our 3-tier user system, and use those baselines to calculate estimated values for the other platforms using an internal multiplier matrix. New Tier: Maps: "New", "Excellent", "Excellent - Refurbished", "Open box", "New with box", "New with defects", and "New without box". Good Tier: Maps: "Very Good", "Good", "Used", "Very Good - Refurbished", "Good - Refurbished", "Pre-Owned", and "Certified Pre-Owned". Poor Tier: Maps heavy-wear options directly ("For parts or not working" or "Fair"). If a specific item category lacks a true "poor" marketplace data option, the engine must automatically fall back to calculate a custom percentage markdown (e.g., 40% less) relative to that item's "Good" tier baseline. Smart Category Specifications (Vehicle & Electronics Handling): If the AI detects an image of a Vehicle or high-value Electronics, the app must dynamically generate a quick-spec form for the user to confirm/fill in (Vehicles: Make, Model, Year, Mileage; Electronics: Brand, Model, Capacity) to feed directly into the pricing API for precise accuracy. 🔹 Milestone 3: UI Redesigns, Audio/Haptics, Live Deployment & Final Handoff ($200 Escrow) UI Tweaks: Implement minor visual layout edits and updates to a few existing UI screens to align with this new calculation model. This includes ensuring tiles are accurately labeled as "Estimated Value," verifying the condition buttons display perfectly, adjusting the selling platform logos/designs, and making a few structural changes to the "Saved Items" page. Haptics & Custom Audio Cues: Implement device vibration triggers (via Web Vibrations API) to pulse the device exactly when a verdict hits the screen. Integrate custom short audio sound bites that trigger instantly on the verdict display: a high-energy "YEAH!" (Lil Jon style) sound bite for a FLIP verdict, and a "HELL NO!" sound bite for a SKIP verdict. “ Live Deployment & Handoff: Successfully deploy the production build live onto our hosting account so the application is fully operational. Clean up the codebase and hand over the complete, finalized source repository. Requirements: Deep expertise in backend optimization, API data pipelines, and high-speed database caching. Proficiency in mobile development frameworks (React Native), front-end audio integration, and Node.js/Python. Strong communication skills. You will work with an existing repository and must provide clean, documented code. To Apply: Please reply with the word "LAUNCH" at the top of your cover letter so I know you read the full description. Explain exactly how you will structure the database cache so that a repeat scan completely bypasses the image-recognition API step to hit the sub-1-second mark globally.

Description We're a real estate team in Tampa Bay. We want a private web dashboard that creates our marketing content for us — on-brand, from our own listings and photos — instead of our team making everything by hand. The core idea: a team member logs in, uploads our brand system once (logo, colors, fonts, headshots, example posts we like), and the AI keeps that brand context saved and applies it to everything it generates from then on. What the dashboard generates: Listing lifecycle content — pick one of our listings, upload the photos, get: • Coming Soon / Just Listed / Open House / Price Improvement / Under Contract / Just Sold graphics (Instagram square + story sizes, Facebook) • Listing flyer (PDF) and "Just Listed / Just Sold" postcard PDFs for the print shop • MLS-ready listing descriptions and platform-specific captions (IG, FB, TikTok, LinkedIn) with hashtag sets Ads — Facebook/Instagram ad creatives (feed, story, carousel) + Google display sizes, with 3–5 ad copy variants (headlines, primary text, descriptions) per listing Short-form video — listing videos for Reels/TikTok built from our photos (motion/slideshow with captions and music), and AI video generation (Higgsfield AI or similar — tell us what you'd use) for lifestyle b-roll and listing teasers; plus reel scripts with hooks for agent talking-head videos Evergreen social — market update graphics, neighborhood spotlight posts, buyer/seller tip carousels, testimonial/review graphics, agent spotlight and just-closed celebration posts — so our feed never goes dark between listings Writing — AI blog drafts we review and publish to our website, just-listed email blasts, open house invite emails, Google Business Profile posts Dashboard features: • Login/logout for our team (a few users) • Brand system upload + management (the AI's saved brand context) • Asset/photo library per listing • Content history — everything generated is saved, re-downloadable, and regeneratable • Content calendar/scheduler — assign generated content to dates, see a "today's post" with reminders, mark as posted (no auto-posting to platforms — we post manually) • Simple and clean UI — this is a daily-use internal tool, not a public site How we want it built: • Next.js 16 (App Router) + TypeScript + Tailwind CSS v4, deployed on Vercel (required — current versions, no pages router) • Supabase for auth, database, and file storage — direct Postgres with Drizzle ORM (do not use Supabase's Data API) • AI image generation (GPT image gen / similar) drives the designs — fed with our brand kit, reference images, and listing context so everything comes out on-brand; LLM APIs (Claude/OpenAI) for all writing • We provide: our full brand assets, our listing data, and examples of the exact style we want — we'll walk you through the details once we start talking You should have: • Shipped recent Next.js (App Router) + TypeScript + Tailwind apps with Supabase (show us 1–2) • Built with AI APIs in a real product — image generation and LLMs (not just chat demos) • Some experience with video generation or programmatic video (bonus, not required) • Clear written English for async updates To apply: start your proposal with the word LIGHTHOUSE, link your most relevant project, and tell us in a few sentences how you'd make AI image generation produce consistently on-brand output from an uploaded brand kit. Applications that skip this are declined.
