Pavel Savinov - Senior Backend Engineer (Go)

Belgrade, Serbia (CET) · open to remote roles, B2B contracts and relocation to the Netherlands or Germany · LinkedIn · getjump.me · getjump0@gmail.com

Four years of production Go on high-volume distributed systems at Avito, Aviasales and Uzum: classifieds, flight search and e-commerce logistics with 15-50M monthly users.

  • Cut search API p99.9 latency from ~5 s to ~500 ms through pprof-driven optimization, caching and request shaping.
  • Took a parcel-sorting system at Uzum from PRD to production in 4 months: domain and PostgreSQL model, Kafka integration via transactional outbox.
  • Kept 20+ promotion microservices at 99.9%+ availability (~3.5k RPS) at Avito.
  • Moved badge logic from mobile and web clients to a config-driven backend: a rollout went from a sprint plus app releases to a 30-minute config change.

Stack: Go, PostgreSQL, Kafka, Redis, gRPC, Kubernetes, Prometheus/Grafana, Jaeger. I use Claude Code and custom agent harnesses in daily work.
