What I'm looking for

I seek backend roles building scalable API-driven and microservice systems, with emphasis on secure payment flows, CI/CD automation, and collaborative Agile teams.

I am a backend engineer with 2+ years building API-driven, microservice-based systems using NestJS and Laravel, focused on reliable schema design, deployment pipelines, and secure architectures.

I have implemented production features including authentication, payment workflows (Paystack, Stripe), NFC-based attendance, a wallet with Google OAuth, and an async notification microservice using RabbitMQ. I contributed to multi-tenant services, caching with Redis, and CI/CD automation with GitHub Actions.

I collaborate in large cross-functional Agile teams, participate in sprint planning and PR reviews, and prioritize secure, testable, and maintainable backend solutions deployed to AWS.
