I'm looking for a skilled developer who can move fast, think creatively, and act more like a partner than a contractor. If you're someone who builds things quickly, brings ideas to the table without being asked, and genuinely cares about creating great experiences for end users, keep reading. -—————- **What You'll Be Working On:** This product sits at the intersection of AI, data, and customer experience. At its core, it needs to: - Monitor and process large volumes of data** in or near real time — surfacing insights, anomalies, and patterns that matter. - Send automated personalized outreach via SMS and email — based on the data signals and triggers, the system should be able to generate and send personalized messages to the right person at the right time, without manual intervention - Integrate with POS systems and CRMs** — pulling, syncing, and acting on data across platforms - Deliver a seamless, intuitive customer-facing experience** — this isn't just a backend tool, how users feel when they interact with it matters enormously - Be built on top of **Claude (Anthropic's AI)** using **Claude Code** as a core part of the development workflow We're in early stages, which means we're figuring things out as we go. That's not a warning — it's an opportunity for the right person. --- **What I'm Looking For:** - Hands-on Claude Code experience** — you've actually built with it, not just read about it. Experts only please - CRM and POS integration experience** — you've connected to platforms like Salesforce, HubSpot, Square, Toast, Lightspeed, or similar, and you know the quirks - Data monitoring and pipeline experience** — you've built systems that ingest, process, and surface meaningful signals from large datasets - Customer experience mindset** — you think about the end user constantly, and you've built tools that real customers interact with - Fast builder, fast thinker** — you're comfortable with ambiguity, can ship quickly, and know how to iterate without everything being perfectly defined upfront - Collaborative and opinionated** — I want someone who pushes back, brings ideas, and helps shape where this goes — not someone waiting for a spec I also want to **learn as we build** — so being able to explain what you're doing and why, in plain terms, is important to me. --- A Note Before You Apply: Please only submit a proposal if you have deep, hands-on experience with Claude Code — not surface-level familiarity, not currently learning it. We're looking for someone who has already put in the reps, knows the ins and outs, and can hit the ground running from day one. We respect your time and ask that you respect ours. If Claude Code isn't already a tool you've mastered, this isn't the right fit. **When You Apply, Please Include:** - Specific examples of tools you've built that involve **CRM or POS integrations** — name the platforms and describe what you built - Examples of **data monitoring or real-time data tools** you've worked on — what did it track, how did it work, what was the scale? - Any **AI-powered products** you've shipped, especially using Claude or other LLM APIs — links, screenshots, or descriptions - How you approach building something when the full picture isn't defined yet - A thought or two on what makes a truly great AI-powered customer experience — I want to see how you think --- **What This Could Become:** This is the beginning of something bigger. The right person won't just be a hire — they'll grow with the product. There's real potential for a long-term working relationship as this evolves.

Project Overview: I am building Reseller Bro, a mobile utility application designed for on-the-go users to analyze product images and instantly retrieve live, accurate marketplace valuation metrics. The front-end user interface and layout are largely complete. The application uses an AI workflow for visual recognition and keyword generation, but the backend data retrieval and sync pipeline needs optimization for speed and absolute accuracy. I am looking for a highly skilled backend developer to conduct a code audit, repair a broken data aggregation pipeline, and optimize our database caching architecture. The Core Tasks: Database Cache Failure: The app currently fails to properly save or recall data on repeat queries. We need a high-speed caching layer so that if an item has already been searched once, the second lookup pulls from the internal database instantly (under 1 second). Data Sync & Engine Accuracy: The live data gathering process is currently unstable and occasionally returns empty results even for common consumer items with deep market history. Once the AI identifies the item keywords, the data pipeline must reliably sync and aggregate live pricing data from major public e-commerce and secondary marketplaces. Data Array / Tier Mapping Mix-up: The app currently handles item condition mapping poorly, sometimes displaying irrational pricing tiers (e.g., valuing low-tier condition higher than top-tier condition). We need a clean pre-fetch matrix that normalizes marketplace conditions into three clean categories on the first search and automatically filters out pricing anomalies or extreme statistical outliers. Required Technical Skills: Strong backend development experience using Node.js or Python. Advanced expertise in data extraction, handling complex HTML/JSON payloads, managing dynamic connection protocols, and optimizing marketplace data synchronization. Deep experience with database optimization and high-speed caching layers (such as PostgreSQL, Redis, or similar). Ability to step into an existing codebase, audit backend logic, and refactor code without disrupting the current frontend UI layout. 💰 Budget & Performance-Based Milestones ($700 Total) This contract is fixed-price and strictly milestone-driven based on functional performance metrics. No milestones will be released without successful live-testing verification. Milestone 1 ($150) - Code Review & Cache Repair: Audit the inherited repository. Fix the database caching system so that previously queried items bypass the live search entirely and load data instantly (under 1 second). Milestone 2 ($250) - Data Pipeline Optimization & Matrix Mapping: Fix the live data aggregation process to consistently pull reliable pricing from target market channels using the AI-generated keywords. Implement data-cleaning and normalization rules to ensure price tiers always reflect a logical tier structure while removing extreme outliers. Milestone 3 ($300) - Final Integration & Testing: Fully connect the optimized database cache, clean data sorting logic, and application backend into a finalized, stable build ready for deployment testing. To Apply: Please respond with your relevant experience in optimizing high-speed database caches and managing high-volume marketplace data aggregation. Please briefly explain your typical approach to ensuring stable, reliable data connections with public e-commerce platforms. Full project source files and existing code repositories will be shared with top candidates during the interview phase.
