Services I Provide
Full-Stack Web Development
I build complete web apps, from the interface people click on down to the database behind it. Most of my work is in React, Next.js and TypeScript on the frontend, with Node.js, Express and NestJS running the backend.
Backend & API Engineering
I build the APIs a product actually runs on: clean REST endpoints, sign-in with email or Google, and permission systems that keep admins, vendors and everyday users in their own lanes.
Database Design & Optimization
I design and tune the databases that hold everything together, across PostgreSQL, MySQL and MongoDB. When queries start slowing down as the data grows, I'm the one who tracks down why and fixes it.
Payment Integration
I integrate payments with any gateway a business runs on, from Paystack to Stripe to Flutterwave and beyond. The work covers subscriptions, one-off charges and wallet systems, plus the parts people forget, like making sure a customer never gets charged twice when the network drops mid-transaction.
AI-Powered Features
I build AI into products, from WhatsApp support bots to agentic systems and retrieval setups like my Docusense project. I work with whatever model fits, OpenAI, Claude or anything else, and tune it on your own data so it answers from what you actually have instead of guessing.
DevOps & Deployment
I set up the pipeline that moves code from my machine to production, with automated builds and deployments through GitHub Actions and Docker. I'm not tied to any single host and can deploy anywhere a project needs to live, from managed platforms to your own cloud servers, so shipping an update stops being a manual, nerve-racking process.
