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!

Job Success
Lagos, Nigeria - 7:58 am local time
Your app is breaking under real users. I fix it and make it production-ready in 5 days. As a Base44 & Replit specialist and Claude Code expert, I rescue AI SaaS MVPs that were built fast but are now unstable.
From broken Supabase auth to failed Stripe integrations, I debug, refactor, and launch your app on a solid architecture. 22+ projects completed, native English, flexible with any time zone.
Right now, your product probably works… but not in a way you fully trust. Maybe it's built on Replit, Lovable, Base44, or stitched together with different AI tools. It got you this far — but under real usage, things feel unstable, messy, or incomplete. That's where I step in.
I take what you've already built, understand where it's breaking (or about to), and turn it into a real production system you can confidently launch and scale.
WHAT I DO FOR YOU
✔ BASE44 & REPLIT APP — I debug, refactor, and secure your existing app. From fixing broken Supabase auth to resolving Stripe integration errors, I ensure your system is reliable under real-world traffic.
✔ FULL-STACK WEB APP DEVELOPMENT — Clean, scalable web applications using React, Next.js, Node.js, and Supabase/Firebase.
✔ AI INTEGRATION & AUTOMATION — Robust, consistent AI agents and chatbots using OpenAI APIs and other LLMs.
✔ DATABASE & BACKEND — Supabase, Firebase, PostgreSQL, MongoDB, authentication systems, cloud deployment on Vercel and AWS.
✔ SAAS & MVP DEVELOPMENT — SaaS platforms, admin panels, client portals, CRM systems, booking systems, marketplace builds, and internal tools.
✔ PAYMENTS & INTEGRATIONS — Stripe, Paystack, third-party APIs, webhooks, and payment gateway integration.
✔ USER AUTHENTICATION & ROLE-BASED ROUTING — I fix auth bugs and role-based routing issues in Base44 and React apps. One client called me "the real deal" after I fixed a critical authentication logout bug leaking sensitive user views. I secure protected routes, isolate admin and user dashboards, and handle invalid sessions cleanly.
WHY CLIENTS COME TO ME
You don't need another developer who just builds what you ask for. You need someone who sees what your product actually needs to survive real users.
Most developers take weeks and charge thousands. I ship your MVP, fix your broken app, or build your AI integration in 3–5 days — clean, stable, and production-ready.
When we're done:
✔ Your system holds up when real users stress it
✔ Your AI behaves consistently, not differently every session
✔ Your backend doesn't slow down or collapse under real traffic
✔ Your MVP isn't just "done" — it's something you can confidently launch
WHO I WORK BEST WITH
I work with founders at two critical stages:
1. You already built something — but it's not stable.
You're close, but things break under real usage and you don't fully trust your product yet.
2. You're at the idea stage and serious about building it right.
Not just an idea in your head — something you're ready to turn into a real product with proper structure from day one.
Ready to build something that actually works? Send me a message with what you're building and I'll show you exactly how I can help.
