We're seeking a skilled Full Stack Developer to join our team. You'll debug and resolve errors within our applications, support improvements, troubleshoot issues, and integrate our apps with our CRM system. Just as important: you'll help keep our GHL-based AI agent and voice AI systems running smoothly for live clients. Read the whole post before applying. We've written it to be direct on purpose. If any of it doesn't sound like you, that's okay , please self-select out. We'd rather know now. What we're looking for We need a contributor, not just a doer. That means someone who takes initiative, spots issues before they become problems for the client, and drives toward solutions instead of waiting to be told what to do next. If you're the type who finds the answer rather than asking us for it, you'll do well here. If you need your hand held on every step, this isn't the right fit. We work with live clients on voice AI and AI agents, so being proactive and responsive is not optional. When something breaks or drifts, we need you evaluating, fixing, and improving it, thinking forward about the end-user experience, not just reacting after a client complains. Responsibilities • Debug and provide solutions for errors in web and mobile applications.. • Support ongoing improvements and optimizations.. • Troubleshoot technical issues efficiently, ideally before they reach the client.. • Integrate applications with our CRM system (GoHighLevel / GHL) for seamless functionality.. • Connect systems and third-party services via APIs to enhance platform capabilities.. • Support, adjust, and maintain GHL AI agents and voice AI workflows so they perform reliably for clients.. Requirements • Proven experience as a Full Stack Developer.. • Strong proficiency in front-end and back-end technologies (e.g., JavaScript, React, Node.js, Python, etc.).. • Experience with GHL CRM integrations.. • Working knowledge of and comfort with GHL AI agents and automations — you don't need to be a specialist, but you should be able to get in, understand how they're built, make adjustments, and pick things up quickly.. • Familiarity with or genuine willingness to dig into voice AI. We expect everyone on the team to be able to work with it.. • Proficiency in designing and implementing REST-based API connections.. • Excellent problem-solving and debugging skills.. • Ability to work independently, take initiative, and meet deadlines.. How we work • We're engaging you — not your agency. The person we hire is the person doing the work. If you subcontract or hand work to others, this isn't a fit.. • Short leash, high trust. Everyone starts on a trial basis. We give people room to learn, but you'll need to learn fast, dive in, and prove it quickly. If you're trying to learn the fundamentals on the job, this role isn't for you.. • Own your outcomes. Bring the thinking, not just the hands. Recognize what the end user's experience will be and drive it.. If that sounds like the environment you want, we'd love to hear from you.

Description: I’m a non-technical founder building SoCalForeclosures.net — a subscription platform for Southern California real estate investors. Lead Members pay $149.99/month (capped at 8,000) to access scored off-market foreclosure and pre-foreclosure leads. Members work leads in a built-in CRM and sell deals through an internal marketplace to cash buyers (free tier or $99.99/month First Look). A working prototype is already built and deployed. Core features including user authentication, PayPal payments, marketplace (SoCalDeals), MyCRM pipeline, Phantom lead scoring engine, admin tools, and bot management screens are functional with demo data on a professional dark theme. Current honest status: The automated “bot army” that will pull real public distress signals from county recorders, courts, tax collectors, legal newspapers, trustees, and paid data sources is scaffolded but not yet actively ingesting live leads. A detailed signal catalog and county data sources are already documented. Project Scope (Fixed Price): I need an experienced senior full-stack developer to take the existing prototype and deliver a fully functioning, production-ready platform that is live and online. This is a single fixed-price engagement. Key deliverables for this project: Full code review and audit of the current Next.js + Express + PostgreSQL + Prisma codebase Polish and improve visual design and user experience across the member dashboard, lead feed, CRM, and marketplace so it looks professional for serious real estate investors Activate and productionize the real data pipeline (bot army) so it can ingest actual leads from public and paid sources according to the existing signal catalog Fix bugs, performance issues, technical debt, and operational problems Migrate hosting from the current European server to a reliable US-based provider with proper deployment pipeline, monitoring, and backups Stabilize the site so it runs reliably in production Deliver clear documentation and handover Important notes: This is not a from-scratch build. A substantial amount of the website and backend already exists and is deployed. The goal of this fixed-price project is to complete the remaining work and launch a fully functioning, live platform with real data capabilities. Once the website is successfully deployed live and online, we will negotiate a separate ongoing contract for maintenance, upgrades, new features, and additional work (including potential iOS and Android mobile apps). Tech stack: Next.js 14 (App Router) + TypeScript + Tailwind Express backend + PostgreSQL + Prisma Existing TypeScript bot framework (Playwright / Cheerio) PayPal payments, Twilio, Resend, Mapbox Ideal candidate: Senior full-stack developer with strong experience in TypeScript, Next.js, Prisma/PostgreSQL, and data pipelines or web scraping (public/government data sources) Experience taking prototypes to production, including hosting migrations and operational stability Comfortable working with an existing codebase and delivering clear recommendations to a non-technical founder Proactive, reliable, and quality-focused Project type: Fixed Price (one set price for the full scope above to get the platform fully live and functioning). To apply, please: Propose your fixed price for completing this project (review + polish + activate data pipeline + hosting migration + full production launch). Share 1–2 examples of similar past work (taking existing code to production, data platforms, or marketplaces). Briefly describe how you would approach reviewing and completing an existing prototype. Confirm your experience with US hosting providers and data pipeline / scraping work. Any questions about the current state or scope. Serious applicants will receive the full technical documents (Developer Brief, Signal Catalog, and County Data Sources) under NDA. Project owner is based in Southern California. US time zones preferred for easier communication.

Firstly, I want to state that I am not a coder. At all. The code I'd like you to review was entirely "vibe coded" using Antigravity and Claude. I don't intend to create a complete product using this method, in fact, I'd like to use real people as much as possible for my business. I used AI during this phase simply to see my ideas made material. I understand that this means the code itself is likely compromised in all sorts of ways, but I'm hoping that you can help me with that. Please speak with me as you would a fifth grader about the technical aspects of the code, assuming you'd like to work together from this point forward. My app is a free-to-user dating and date planning app that connects people through locally owned businesses. It serves two audiences: - **Singles** looking to meet and go on dates with other singles in their area - **Couples** looking for date night inspiration through a linked accounts mode

ABOUT THE PROJECTS. I run a curated marketplace on Shopify (The Ever Good) and I am building out an AI automation system to handle routine tasks in the business. I am AI-savvy and have built a Python agent myself, so I understand what I am asking for. I have the architecture planned and the business requirements semi-documented for each piece. I simply do not have the time to build everything I want to build, which is why I need a developer to work alongside me. The first project is a product review collection and import system. If it goes well, there is ongoing work building out additional agents over time, one at a time. This is a potential long-term engagement depending on how the first project goes. WHAT WE ARE BUILDING. The overall system is a set of AI agents that handle specific business tasks and route outputs to a simple dashboard where I can review, approve, and trigger actions before anything goes live. The dashboard is a Lovable build that gives me a single place to monitor agent status, review outputs, and approve or return anything that needs a human decision before it moves forward. Agents are planned across several areas of the business. We will build one at a time. I will walk you through the requirements for each before you start. Examples of agents here by business category (these could change): - MARKETPLACE & CATALOG. Product Reviews (first project), Catalog Enrichment and SEO, Pricing and Margin Monitor, New Product Auto-Pricer, Maker Stories, Maker Audit, Maker Analytics, Review Monitor. - CONTENT & SOCIAL.

HOW WE WORK. - HOURLY. Collaborative and iterative engagement. - REQUIREMENTS. We review together before each build and refine as we go. - QA. I handle testing and QA on my end. - DOCUMENTATION. All work is documented throughout with decision logs and handoff notes so full ownership and control remains with me at every stage. - IP. All intellectual property and work product belongs to me entirely. - CLAUDE. You are expected to maintain your own Claude environment at a level that supports serious development work with no usage limitations. - ACCESS. All business systems and APIs provided with scoped credentials as needed. - DEPLOYMENT. Production deployment is handled collaboratively. - COMMITMENT. Looking for someone who can help maintain and evolve these tools over time while I retain full control and understanding of everything we build. WHAT I AM LOOKING FOR. - CLAUDE. Must use Claude as your central AI LLM. Experience. Working experience with the Claude API and the tools in the building stack above, or a demonstrated ability to learn new tools quickly. - COMMUNICATION.Clear communicator who works independently and does not need to be managed through a task, but is promptly responsive to me. - MINDSET.
