What I'm looking for

I'm looking to build reliable backend and full-stack products, lead services from architecture through deployment, and solve complex payments, marketplace, and AI platform challenges.

I'm leading backend and DevOps delivery for Jyro, an errand marketplace, building APIs, wallet workflows, payment processing, agent onboarding, and secure financial operations. I've integrated Safe Haven banking APIs and Sudo Africa card infrastructure while establishing CI/CD, testing, monitoring, and release standards.

Previously, I improved response times by 40% at Yuniq Solutions and built AI recruitment features, including semantic search, RAG, and vector-based job matching, at Workonnect Africa. I build with Node.js, NestJS, TypeScript, PostgreSQL, MongoDB, Redis, AWS CDK, React, and Docker.
