What I'm looking for

I’m looking to build and optimize backend systems—scalable APIs, distributed services, and cloud deployments—where I can improve performance, reliability, and delivery speed using Python, CI/CD, and infrastructure best practices.

I’m a Backend Engineer based in Tashkent, Uzbekistan, focused on building reliable distributed systems and APIs. I’ve delivered backend features that support large user bases and improve real-world performance.

At Datatruck Inc, I developed a Task Management module used by ~90% of clients and implemented a serverless file upload solution that unblocked 64+ service workers under heavy load. I also optimized memory utilization by ~9x by fixing memory leaks and resolved a high-load container crash that caused data loss.

Earlier, I maintained the HR management backend for ~500,000 users at Alabuga SEZ and cut spreadsheet download time by 20x. I built billing and payment backends at Mohirdev LLC, automated delivery with CI/CD (about 10 minutes), orchestrated scalable Docker Swarm deployments, and reduced total job duration from 1.5–2 hours to 3 minutes.
