About Me

My name is Teslim Sadiq. I am a Software Engineer from Lagos, Nigeria, focused on building scalable systems that are reliable, maintainable, and useful under real business constraints.

I work across backend architecture, API design, data modeling, distributed workflows, and product-facing interfaces. My core stack includes TypeScript, Node.js, React, Python, FastAPI, PostgreSQL, MongoDB, Redis, and queue-based systems.

I have shipped systems across edtech, civic tech, fintech, AI tooling, and consumer products. I care about clear engineering decisions, dependable execution, and building software that can scale without becoming difficult to change.
