What I'm looking for

I want to build backend systems—microservices, APIs, and reliable payment/subscription workflows—where I can own features from design to deployment and keep improving performance and production reliability.

I’ve been building microservices for OneGen Social Innovations Labs, working on Inner Explorer’s content APIs and progress tracking engine to support high-concurrency user sessions.

I designed a SaaS subscription system, integrated secure payment workflows with idempotency and reconciliation, and built a self-service CMS that cut manual operations and turnaround time. I also own end-to-end feature delivery from design to deployment and worked on a KYC onboarding pipeline for 1000+ vendors.
