Olatunde Success | Senior Full-Stack Software Engineer

Engineer

Hi! I'm Success, a full-stack engineer
building fintech and legal tech from Ibadan, Nigeria

For 8+ years I have shipped production software across backend, frontend, mobile, and DevOps: payment rails, escrow engines, real-time services, and scalable APIs. I lead engineering on Dbrij, Cirva, and Resikonet at SAW Technologies, build core banking services for Confidence MFB, and helped bring the PODUS legal-tech ecosystem to 35,000+ users. I care about secure, test-driven, well-documented systems that survive contact with real money and real people.

What I Do

Backend & Fintech Systems

Payment rails, escrow engines, real-time services, and scalable REST/GraphQL APIs on Node.js/NestJS, Java, Laravel, and Python.

Frontend & Mobile

React/TypeScript and Next.js on the web; React Native, Flutter, and native Android (Kotlin/Java) on mobile. Component-driven and accessible.

DevOps & Security

CI/CD on GitHub Actions, AWS/GCP/Azure, Docker, observability with Datadog and Sentry, plus OWASP-aligned secure development and NDPA 2023 compliance.
