I’m a results-driven Backend Engineer with 6+ years of experience designing and building scalable, high-availability distributed systems. I’ve led backend architecture from zero to production, with hands-on work across real-time platforms, payment infrastructure, and microservices.

At TradeBanta, I architected and deployed a high-availability Node.js/TypeScript backend from scratch. I designed a microservices architecture using Docker and RabbitMQ, built resilient WebSocket infrastructure for live price changes and trade confirmations, and integrated Paystack wallet systems (virtual accounts, withdrawals, and escrow logic).

I also owned KYC verification flows using BVN/NIN validation providers, and managed PostgreSQL architecture alongside CI/CD deployment pipelines and sprint planning. My approach prioritizes reliability, observability, and clean delivery from architecture through rollout.

Previously, as a Senior Software Engineer at Apptalics, I led backend development and delivered production-grade mobile application features through APIs integrated with Flutter clients. Earlier, as Co-founder & CTO at Abular.com Web Services LTD, I led a team using Flutter and Golang/Gin, overseeing system architecture, code quality, product delivery, and building an enduring engineering culture.
