What I'm looking for

I seek roles where I can lead backend or AI infrastructure efforts, solve scalability challenges, mentor teams, and contribute to cross-functional product delivery in a collaborative, growth-oriented company.

I am a senior software engineer with 17 years of experience building high-volume, scalable systems across backend, frontend, and infrastructure. I specialize in Python and Golang and have a strong track record delivering production services with emphasis on performance and reliability.

I have worked as a consultant and in-house engineer for startups and large organizations, leading small teams, mentoring engineers, and collaborating closely with UX, product, and engineering managers. My projects include a high-traffic voting system (Guinness World Record), marketplaces, and AI-driven content pipelines.

My recent work includes developing an AI-powered question-generation pipeline for an education platform, building an NFT marketplace and payment flows, and delivering consulting services to international clients. I routinely work with Kubernetes, Docker, Terraform, Redis, Mongo, PostgreSQL, cloud providers, and modern web frameworks.

I bring technical leadership, strong communication, and a pragmatic approach to cross-functional collaboration, aiming to ship reliable systems, improve operational costs, and enable teams through tooling and automation.
