Software
Engineer
I focus on writing clean, efficient code and thrive in collaborative environments.
I am all in — attention to details, thoughtful, structured, and test-driven.
Crafting real-time systems, architecting software, and mentoring the next generation of developers.
Engineering
In building applications, I'm equipped with just the right tools, and can absolutely function independently of them to deliver fast, resilient solutions designed for scale — performance and scalability are a priority for me.
Security
As a professional software developer, I apply cybersecurity best practices at every stage of the development process. From securing APIs using JWT and OAuth2, performing SAST and DAST vulnerability tests using SNYK and OWASP ZAP, to mitigating common vulnerabilities (XSS, SQL injection, CSRF), I create applications with security in mind, bringing a strong security mindset to every project.
Over the years
Over the years, I've built products for companies and businesses around the globe — from e-commerce websites to complex, enterprise-grade applications — with a focus on fast, elegant, and accessible user experiences.
Currently, I'm Co-Founder and Principal Engineer at SPOX, a real-time sports-performance trading platform, where I own the frontend architecture, contribute across the backend, and lead security and compliance for a system that handles real user funds.
Before that, I was a Frontend Developer at C-Sunshine, building tools and services for medical practitioners and a large-scale fitness app.
Prior to C-Sunshine, I worked as a Frontend Developer with Nanocodes, building JavaScript applications and interfaces for organizations and individuals.
Earlier in my career, I was a Frontend Developer at Global Network LLC, where I led frontend development on whatido, a professional social media startup — building video-heavy, live-call React applications — while also implementing blockchain payment automation, multi-currency payment integrations (Paystack, Stripe), and Elasticsearch-powered search.
