Job Success
Hauxton, United Kingdom - 2:26 pm local time
My main stack is React Native, React, NestJS, Node.js, and .NET. I’ve also worked extensively with Stripe, PostgreSQL, Supabase, AWS, Azure, Cloudflare Workers, and production-grade API integrations.
Most of my work involves taking a product from an early idea or an unstable codebase to something reliable, scalable, and ready for real users. That includes architecture, development, deployment, App Store and Google Play submissions, payment flows, third-party integrations, and production troubleshooting.
A few examples of my work:
Dalmore Group — Built backend systems for an investment platform processing more than 10,000 transactions per day. The platform included complex trade workflows, KYC/AML processes, AI document extraction, BullMQ queues, XState state machines, and audit-ready reporting.
Gymnastrio — Developed a gym management SaaS using React, .NET Core, PostgreSQL, and Stripe Connect for class bookings, personal training, and multi-party payments.
Swake — Built a customer feedback SaaS using React and NestJS, with SDKs for React Native, Ionic, and web applications.
Docomi — Developed an AI customer support platform with RAG, workflow-based chatbots, semantic search, and knowledge ingestion from websites, Notion, Zendesk, SharePoint, and uploaded documents.
MyDiabeticHealth — Built and launched a React Native app using Expo, Supabase, and RevenueCat on both iOS and Android.
Vontrix VPN — Worked on a consumer VPN app connected to a 1,000-server WireGuard network, with subscriptions, AdMob, RevenueCat, and automated server updates.
I can help with:
• React Native and Expo apps
• Full-stack SaaS platforms
• .NET and ASP.NET Core development
• React, Next.js, NestJS, and Node.js applications
• Stripe, subscriptions, marketplaces, and payment flows
• AI integrations, RAG systems, and LibreChat
• API development and third-party integrations
• App Store and Google Play submissions
• Architecture reviews, performance issues, and production bugs
I lead the technical direction and client communication myself. For larger builds, I work with a small senior team through my agency so we can move faster without lowering the quality of the work.
Share your product idea, existing codebase, or technical problem, and I’ll give you an honest view of the best way to approach it.
