About Me

The engineer
behind the build.

Full-stack software engineer currently based in England, United Kingdom. I started with hardware in 2018, picked up software in 2019, and haven't stopped shipping since. I build complete products — schema to screen, database to deployment.

My Story

Hardware first.
Software always.

I started with hardware engineering in 2018 — circuits, microcontrollers, embedded systems, and the deeply satisfying discipline of making physical things work. That foundation taught me something most software engineers never learn: precision is non-negotiable. A wrong wire doesn't produce a runtime error. It just fails.

"I don't just write features. I think about data integrity, security models, deployment pipelines, and what happens after the first user."

I picked up software development in 2019 — while still deep in hardware. That overlap gave me a different kind of systems thinking. When I write a database schema, I think about it like a circuit board: every relationship has a purpose, every constraint is load-bearing.

I graduated from NIIT (Software Technology School) and the University of Sunderland in the UK (2023), building commercially while still in school. I've done internships, worked across engineering and design teams, collaborated with developers, designers, product managers, and business owners across multiple projects and industries.

Today I'm the sole architect and engineer behind Fitt — a production mobile app for fashion designers — and I previously built the backend and both mobile apps for Impala, a multi-vendor marketplace targeting Nigerian vendors. With 100+ GitHub repositories spanning private works, full-stack apps, AI tools, admin dashboards, and hardware-software integrations, the catalogue is real.

01
Production-ready from day one
No "we'll clean it up later." Every function is typed, every query is scoped, every RLS policy is written before the first user touches the app. Technical debt is a product risk I don't ship.
02
Verify before building
I check actual database state before writing code, confirm before implementing, and test against real data. Assumptions are where bugs live.
03
Security is architecture
Row Level Security isn't an afterthought — it's the first thing I design. Hashed PINs, scoped queries, proper RLS policies embedded in the schema, not bolted on after.
04
Rewrites over patches
When complexity breaks down, I rewrite cleanly. I'm not precious about code — I'm precious about outcomes. A clear codebase is a maintainable product.
05
End-to-end ownership
Schema migrations, API design, mobile UI, push notifications, App Store submission — I own the whole surface. No handoffs. No gaps. Just the product.

Journey

From circuits to code.

6+ years of building across hardware, software, education, and production — all in one timeline.

Hardware Roots

Before the code,
the circuit.

From 2018 to 2022 I was a hardware engineer — working with electronics, repairs, embedded systems, and circuit design. It wasn't a detour. It was the foundation.

That background shapes everything about how I write software today. When I design a database schema, I think about physical constraints. When I write an RLS policy, I think about access layers the way I used to think about voltage regulators. Every abstraction protects something real underneath it.

Most engineers learn to think in systems through software alone. I learned it in hardware first — where you can't hide from the consequences of a wrong decision.

How I Work

Engineering philosophy.

01 /
Production-ready from day one
No "we'll clean it up later." Every function typed, every query scoped, every policy written before the first user touches the app.
02 /
Verify, then build
Check actual database state before writing code, confirm before implementing, test against real data. Assumptions are where bugs live.
03 /
Security is architecture
Row Level Security, hashed PINs, scoped queries — designed into the schema from the start, not patched in afterwards.
04 /
Rewrites over patches
When complexity breaks down, rewrite cleanly. Not precious about code — precious about outcomes. Clarity compounds.
05 /
Mobile-first, always
Build for the device in the user's hand, on their actual network. Performance-aware, offline-considerate, designed for real usage patterns.
06 /
End-to-end ownership
Schema migrations to App Store submission — I own the whole surface. No handoffs, no gaps, no "that's someone else's part."
07
Collaboration

Who I've worked with.

Building solo doesn't mean working in isolation. I've collaborated across functions, teams, and disciplines.
