Profile

I evolve business-critical backend systems while continuing product delivery. My work spans business logic and integrations, runtime and data modernization, and production reliability. I own technical decisions from design through production.

Targeting a hands-on Senior Java Engineer role with a technical growth path. Interested in product backend or platform teams with a strong engineering culture and relocation opportunities within the EU.

Experience

Senior Java Developer / Team Lead

Restream Media · Wink

2016 — Present

At Wink, I owned backend areas for subscriptions, purchases, and integrations, serving around 10M monthly users. Each macro-regional deployment handled around 300 RPS and stored around 2 TB of data.

Selected impact

  • Delivered new purchase and subscription methods, evolved integration flows, and separated B2B functionality into a dedicated subproject.
  • Designed and built authorization and API gateway services for the core product.
  • Drove incremental modernization from Java 6 to Java 21 and Spring Boot 3.5 while continuing product delivery.
  • Replaced ad hoc Oracle scripts with managed Liquibase migrations; optimized SQL and refactored the DAO layer.
  • Evolved NSQ event flows with typed messages, deduplication, and a persisted outbox.
  • Added Actuator, Prometheus/Micrometer, readiness checks, request tracing, and Oracle Testcontainers tests.
  • Provided technical direction for a five-engineer team, interviewed around 20 candidates, and hired five engineers.
