What I'm looking for

I'm looking for a full-time remote role where I can own scalable backend, payment, real-time, and infrastructure challenges while building reliable production systems.

At Petrong Software Solutions, I engineered backend services for FxKaraSell, BriniFoods, and AgeWell, supporting 500k+ monthly transactions with 99.99% uptime. I built multi-tenant SaaS workflows, idempotent Stripe and Paystack payments, real-time notifications, and PostgreSQL/PostGIS optimizations that improved query performance by approximately 120–130%.

Previously, I built reservation marketplace and delivery-platform systems at CityGuideX and Huelage Inc., spanning Next.js, GraphQL, MongoDB, secure JWT/RBAC authentication, real-time tracking, testing, and cloud infrastructure. I take ownership of complex backend and infrastructure challenges and am immediately available for full-time remote work.
