Project details
I provide end-to-end product management services for Food Tech and Restaurant SaaS platforms, specializing in prototyping, design, and detailed specifications. This service is ideal for startups and growth-stage companies looking to turn product ideas into actionable, developer-ready solutions.
The process begins with understanding your product goals, target audience, and key features. I then create wireframes, user flows, and interactive prototypes that visually communicate the product experience. Detailed product specifications are prepared alongside design assets to ensure developers have clear instructions for implementation.
My approach emphasizes usability, scalability, and alignment with business objectives. Deliverables include polished prototypes, comprehensive specs, and handoff-ready documentation. This service helps teams reduce development errors, streamline workflows, and accelerate time-to-market for web, mobile, or SaaS applications.

Stripe webhook failure on full stack AI app
Joel is a master at API and payment integrations. Our full-stack app was completely dropping Stripe webhooks, leaving paying customers stranded. Joel found the exact parsing bug in our Express backend immediately, patched it cleanly, and added extra database protection against duplicate events. Fast, brilliant communication, and highly professional. Will absolutely hire again!

Replit web app deployment and console error fixes
Joel turned a nightmare launch week into a total success. Our Replit application was completely broken on deployment with brutal console errors, and he jumped in and resolved it in a short while. He fixed our environment variables, secured our auth, and got us live seamlessly. If you have a full-stack app stuck on Replit, hire Joel immediately. 10/10 developer!

OpenClaw / n8n workflow automation error troubleshooting
Joel completely saved our automation pipeline again!. Our OpenClaw and n8n setup was dropping data and generating messy database errors under traffic, and he fixed the entire asynchronous payload issue in no time. He's an absolute expert with AI agents and database syncing. we are going to discuss a larger contract to hand over our full automation infrastructure to him!

Fix messy AI-generated code from Lovable app (Next.js/Node)
If you built your MVP using Lovable or other AI tools and it's starting to break under real traffic, save yourself the headache and hire Joel immediately. He completely understood how AI generates messy, redundant code and accurately diagnosed our silent API drops and Stripe payment failures in less than two hours. A true full-stack expert, we started with this $10 audit and are absolutely hiring him to clean up and scale our entire SaaS platform!

Need help running Claude Code from terminal to fix broken API
Joel is an absolute lifesaver. We were stuck on a brutal OpenAI API sync and authentication bug in Replit that was throwing random console errors. He jumped in instantly, used Claude Code to debug the entire backend stream in a short time, and even added a custom error-logging feature to keep our database stable. His technical speed is unreal, and he explains things so simply. We started with this $10 trial and we are 100% hiring him for the rest of our full-stack MVP development. Highly recommended!

That's exactly what I do.
I'm Joel, a Full Stack AI Developer specialising in Claude Code, Base44, Lovable, Replit, and Bolt. I build production-ready AI apps, SaaS platforms, mobile apps, and AI agents for founders, startups, and agencies — shipped in days, not weeks.
Clients usually come to me in one of two situations:
YOU HAVE AN IDEA AND NEED IT BUILT FAST
I take you from concept to a launched MVP — authentication, database, payments, and a clean responsive UI — using React, Next.js, TypeScript, Node.js, Tailwind CSS, and Supabase, with Stripe wired in so you can charge from day one. I build AI SaaS platforms, web apps, mobile apps (iOS & Android), AI agents, admin dashboards, and client portals that go live with zero technical burden left on you.
YOU HAVE AN AI APP THAT LOOKS GREAT BUT BREAKS
Apps built in Base44, Lovable, Replit, or Bolt often fall apart under real users — broken auth, failed payments, console errors on deployment. I specialise in inheriting and stabilising these builds: auditing the architecture, finding the root cause, fixing it cleanly, and deploying to mobile or web.
WHAT I BUILD AND FIX
✅ AI SaaS MVPs — Full-stack web apps and SaaS platforms using Claude Code, Base44, Lovable, React, Next.js, and Supabase
✅ Mobile Apps — iOS & Android via React Native and Capacitor, including mobile store submission and deployment
✅ AI Agents & Chatbots — Claude API, OpenAI, RAG systems, and agentic workflows built for real production use
✅ Workflow Automation — n8n, Make, Zapier, and GoHighLevel automations connecting your tools and eliminating manual work
✅ Payments & Integrations — Stripe, Paystack, REST APIs, webhooks, and third-party integrations handled properly
✅ MVP Rescue & Debugging — Base44, Lovable, Replit, or Bolt app broken? I diagnose, fix, and ship it stable
✅ Claude Code Setup — MCP integrations, Claude configuration, and agent tooling for your dev workflow
A FEW RECENT WINS
→ Fixed a critical Stripe webhook failure dropping paying customers on a full stack AI app — found the exact parsing bug and resolved it same day
→ Turned a nightmare Replit deployment with brutal console errors into a full launch in under a week
→ Repaired a Base44 authentication logout bug leaking sensitive user views — secured all protected routes and deployed clean
→ Fixed an n8n and OpenClaw automation pipeline dropping data under traffic — resolved the async payload issue end-to-end
WHY CLIENTS KEEP WORKING WITH ME
Fast, proactive communication — I don't go quiet mid-project. A visible win early so you feel real progress in week one. Clean, documented code your team can build on. And honest scoping — I'll tell you upfront what it takes to ship.
