What I'm looking for

I want to build and scale backend systems—design clean REST APIs, optimize databases, and improve reliability—working with teams that value performance, engineering quality, and smart technology choices.

I’m a Backend Engineer with 7+ years of experience focused on building scalable web systems. I design and implement REST APIs, integrate with third-party services, and choose technologies based on the task—adapting quickly when new tools are needed.

In my recent role, I developed and maintained an e-commerce platform and an internal admin system, integrating with marketplaces and supplier APIs. I’ve optimized MySQL queries for better database performance, refactored legacy code to improve system stability, and delivered fullstack solutions using Vue.js and Node.js across cashback platforms, motivation systems, and bots.
