What I'm looking for

I'm looking to own architecture for high-throughput distributed systems, solve performance and scalability problems, and mentor engineers in a fast-moving team.

I'm leading Newroz Technologies' migration of a legacy PHP travel platform to Go, moving services toward stateless, horizontally scalable architecture. My work reduced maximum response payloads from 6–7 MB to about 1 MB and lowered CPU usage from roughly 50% to 5% on 2-core servers.

I built distributed circuit-breaking and supplier-response caching systems that contain supplier failures and reduce average API latency from 10+ seconds to milliseconds. I also lead architecture decisions and mentor a three-person engineering team.

Previously, at TechnoNext Software and Brain Station 23, I built geospatial, caching, record-management, and computer-aided dispatch systems using Go, Node.js, React.js, SQL databases, Redis, and cloud infrastructure. I've improved query latency from 800–900ms to 100–150ms and scaled cached workloads beyond 1,000 RPS.

Newroz Technologies Limited

Apr 2026 - Present (5 months)

Leading the technical migration of a legacy PHP travel platform to Go, migrating ~50% of services to date with a focus on statelessness and horizontal scalability. Replaced filesystem-based state with Valkey, cut response payload size from 6-7 MB to ~1 MB, and reduced CPU usage on 2-core servers from ~50% to ~5%.
