What I'm looking for

I seek roles where I can modernize systems, lead end-to-end web platform delivery, implement robust CI/CD and testing, collaborate cross-functionally, and drive measurable performance and reliability improvements.

I am a Senior Full Stack Engineer with over 7 years of experience specializing in Rust (Axum), TypeScript, and MongoDB/Redis. At Zenith Bank, I architected an FX conversion system that supported 8,000+ users with 99.9% uptime and reduced processing times by 85%. I excel at modernizing legacy monoliths into modular services, having achieved an 85% latency reduction in trade systems by optimizing database queries from 300ms down to 45ms. My career is defined by building "bulletproof" systems through type-safe API contracts, immutable event sourcing, and automated testing with Playwright. I am passionate about mentoring developers and advocating for architectures that balance immediate delivery with long-term scalability.
