What I'm looking for

A remote backend engineering role where I can own features end-to-end — from system design to deployment. Ideally a small or async-first team working on meaningful infrastructure, platform, or automation challenges.

I'm a senior backend engineer with 18+ years of experience delivering production systems end-to-end — from architecture design to deployment and operational tuning. I specialize in Linux-based self-hosted infrastructure, high-concurrency backend systems, and workflow automation.

Most recently, I've been the sole technical owner at a leather goods company, building multilingual e-commerce platforms, integrating OpenAI and logistics APIs, and designing intelligent traffic management systems using tc, nftables, and policy routing. Earlier in my career I built C-based Linux services, LAMP-stack platforms, SNS backends, and customized Magento/WordPress/Joomla systems.

I work best in small or remote-first teams where I can own backend features independently and ensure reliable production operation.
