I'm Samson Okunola, a software engineer in Lagos. I design and build products end to end: core banking, learning platforms, CRM tools and AI assistants.
Profile
I work across the whole life cycle: design, APIs, interfaces, testing and deployment. I do my best work in small, trusted teams, where every technical call can be traced back to the person using the product. I like teaching as much as learning.
Interfaces in React, Next.js and Vue. Typed end to end, tested, and fast on the devices people actually own.
TypeScript, JavaScript, React, Next.js, Vue, WebGL, Vite, Webpack, Turbopack, Babel, Jest, Vitest, React Testing Library, Cypress, Playwright
Services and APIs in Go, Rust and Node, on Postgres, Mongo and Redis. Boring where it should be.
Golang, Rust, NestJS, Express.js, Gin, Fiber, Axum, FastAPI, PostgreSQL, MongoDB, Redis, SQLite
Assistants with retrieval and MCP tools, and the OCR service behind a whole product ecosystem.
Python, LangChain, RAG, MCP, Vector DBs, OCR
Containers, pipelines and the clouds they land on: AWS, Azure, GCP, Vercel.
Docker, Azure, AWS, Google Cloud Platform, Vercel, Render, Railway, Jenkins, Groovy, Git

I also designed database schemas and foundational system architectures for key projects, helping establish scalable and robust technical foundations.
Engineering Lead
Designed and architected the entire software system from the ground up, establishing its foundational infrastructure, APIs, and microservice architecture. I developed backend microservices using a polyglot approach, leveraging Golang for high-performance services and Python for specialized workloads. I also led the development of a suite of frontend applications using Next.js, including the B2B Console, Admin Dashboard, and public User Application across web and mobile.

01 — Side project
Kestrel is a tool for performance-testing HTTP APIs. Add an endpoint, or import a whole API from an OpenAPI spec, Postman collection, HAR file or curl commands. Then measure how fast it responds, how it holds up under load, how it handles concurrent writes, and how its latency grows with input size. While it runs, it checks responses against your spec.

A real-time collaborative whiteboard. Open a board, share the link, and everyone on it draws and edits together, with live cursors. It's built around a plugin interface for custom shapes and tools, and it has no paid dependencies: the only costs are a server and a Postgres database.
