About Me

Building Production Systems
That Actually Work

I'm a backend-focused software engineer with 4+ years of experience building systems where reliability, performance, and correctness aren't optional—they're essential.

My Background

I started my career after completing the MEST Africa software engineering program in 2020, where I learned to build products that solve real problems. Since then, I've worked across fintech, trading platforms, and retail systems—always on the backend where the critical logic lives.

At Skippa Trading, I built notification infrastructure that needed to be faster than competitors—and maintained 99.9% uptime because traders don't wait for slow systems. At BusyParade, I designed BusyOs from scratch: a complete POS system handling real money, real inventory, and real business operations.

What sets me apart isn't just technical skill—it's my ability to own problems end-to-end. I don't just write code; I understand business requirements, design appropriate solutions, implement them cleanly, and make sure they work in production. I'm the developer you can hand a problem to and trust to come back with a solution that actually works.

Philosophy

How I Work

Ownership Mentality

I don't just complete tasks—I own outcomes. From initial design to production deployment, I take responsibility for the entire lifecycle of features I build.

First Principles Thinking

I understand the 'why' behind technical decisions. This helps me make better architectural choices and avoid common pitfalls that cause problems at scale.

Clear Communication

I bridge the gap between technical complexity and business needs. Stakeholders trust me to explain tradeoffs and keep them informed without jargon.

Quality Over Speed

I write code that other developers can understand and extend. Tests, documentation, and clean architecture aren't afterthoughts—they're built in from the start.
