About

I am a hands-on senior backend engineer and technical lead with an M.Sc. in Computer Science from Amirkabir University of Technology. My work spans distributed backend systems, real-time media, platform engineering, and Linux.

The strongest part of my work sits where architecture and implementation meet: defining service boundaries, making trade-offs explicit, and designing for failure before systems scale. I have led small engineering teams while continuing to contribute directly to production code.

I am currently focused on senior backend, platform, and technical-lead roles in the EU, with employer-supported relocation to Germany or the Netherlands and selected remote engineering or architecture engagements.
