About this gig

I build complete web products, not just front ends. SaaS platforms, internal systems, progressive web apps and single page apps, with the backend and database underneath them.


I ship production software at Flutterwave, Africa's largest payments company. Before that I was founding engineer at Kadavra BDC, where I built Odysy, a travel focused fintech with virtual USD cards and mobile money, from an empty repository.


What you get:

Architecture and data modelling, not just screens

Authentication, user roles and permissions

Payments and subscription billing

An admin panel so you can run the business

A REST or GraphQL API

Database design and migrations

Deployed live, with the source code handed over


My stack: React, Next.js, Vue, Nuxt, TypeScript, Node.js, NestJS, Express, Python, PostgreSQL, Supabase.


I would rather build the right small thing first than take your money for the wrong big thing. If you are not sure which package fits, message me and describe what you are building, and I will tell you honestly what is realistic at each level.

I am a full-stack engineer with 6+ years building production software that businesses actually run on. I built the loan dashboard at Flutterwave, Africa's largest payments company, which has enabled over $5M in merchant lending, and I was founding engineer at Kadavra BDC, where I built the treasury, FX and card operations portal. I work across the stack: React, Next.js, Vue, Node, Python, PostgreSQL and Supabase. I build web apps, SaaS products, dashboards, internal tools and e-commerce, plus AI integration and automation. Happy to start from an empty repo or take over an existing codebase.
