Senior Engineer

Distributed systems · Full-Stack · Cloud infrastructure · AI/ML platforms

I build systems where scale, reliability, latency and cost all have to hold at the same time.


About

Software engineer, working end to end, from low-level performance and Linux servers, through distributed architecture, to user-facing applications.

  • Architecture - service boundaries, data modeling, and the trade-offs behind them
  • Performance - profiling, serving-path optimization, p99 over averages
  • Reliability - failure modes, fault isolation, observability, incident response
  • Cost - capacity planning and resource utilization as design constraints
  • AI/ML infrastructure - inference serving, RAG pipelines, evaluation systems, GPU workloads

I care less about using the newest technology and more about choosing the right abstraction for the problem.
