What I'm looking for

I am looking for a high-ownership role at a product-led company where I can architect and scale backend systems using Go, Nodejs and Python. Having built and launched a live e-commerce platform from the ground up, I thrive in environments that value transitioning MVPs into production-hardened systems that serve real users.

I am a Performance-Driven Software Engineer with a passion for architecting high-concurrency systems and scaling products from MVP to production-ready status. My career is defined by a "bottom-line" engineering philosophy: I believe that backend architecture exists to drive business growth, user retention, and system reliability.

What I’ve Done

Built from Scratch: I architected and launched PearlsByRay, a live e-commerce platform. I handled everything from the PostgreSQL schema design to the integration of resilient, idempotent payment gateways and asynchronous background tasks.
Scaled for Performance: In my work with international firms, I’ve specialized in Go (Golang) and Python, successfully slashing API latency by 20% and reducing production bugs by 30% through the implementation of automated testing frameworks and observability tools.
Led & Mentored: As a Software Development Instructor at Execute Tech Academy, I don’t just write code—I teach it. I’ve mentored dozens of engineers on the principles of database normalization, secure API design (OAuth2/JWT), and clean code architecture.
