About Bogdan

Senior backend engineer with 8 years of experience, the last six spent building real-time data ingestion and
low-latency distribution systems for live competitive events watched by millions. At ESL Gaming (EFG), I architect
the Node.js/TypeScript platforms that capture live match telemetry, enrich it beyond what public APIs expose, and push it
with sub-second latency to broadcast graphics, in-arena screens, hardware controllers, and external data partners — in
an environment with zero tolerance for downtime: every failure is visible to a live audience. Deep expertise in
event-driven architectures, WebSockets, high-frequency event handling, and partner-facing data APIs. Looking to apply
live-event reliability engineering to real-time sports data, trading, or streaming platforms.

Experience

  • ESL Gaming (EFG)
    Senior Software Engineer — Real-Time Broadcast Systems
    DIGITAL AND IT
    February 2020 - Today (6 years and 6 months)
    Bucharest, Romania
    Own the end-to-end real-time data platform for Tier-1 tournaments across four game titles (Counter-Strike, Dota 2, Rainbow Six, Rocket League). Systems deployed live at 30+ international tournaments, including the IEM Cologne Major 2026 (CS2 Major Championship, Lanxess Arena, 1M+ peak concurrent viewers) and the largest events in esports: IEM Katowice, Esports World Cup, Six Invitational.
    Live telemetry ingestion: architected centralized Node.js event servers that ingest live match telemetry per title and act as the single source of truth for every downstream consumer during an event.
    Proprietary data enrichment: built custom memory-reading modules that capture granular in-game data unavailable through official/public APIs, giving the production a faster, richer feed than any third party — the same speed-and-depth edge that drives live sports data products.
    Computer-vision data capture: for titles with no API at all, implemented computer-vision extraction that turns raw gameplay video into live structured event data, reliable enough to drive stage integration in real time — the same class of problem live sports data providers solve when capturing events from venues without official feeds.
    Low-latency distribution: engineered real-time pipelines pushing live player statistics and state changes to arena screens and broadcast graphics, keeping stadium audiences of thousands synchronized with the live game state.
    High-frequency event handling: optimized the pipeline for rapid bursts of match events guaranteeing instant graphic updates and replay transitions under load.
    Algorithmic decision systems: deployed camera-switching logic that drives professional vision mixers automatically from live game state — machine decisions executed on physical hardware in front of a live audience.
    Zero-latency show control: connected live match data to stage FX (lighting, pyrotechnics) and Ross XPression broadcast graphics, triggered in real time by in-game events.
