Senior Backend Engineer with production experience building cryptocurrency exchange platforms and real-time market data infrastructure from the ground up.
Architected and delivered IRBTC — a production-grade crypto exchange backend handling fiat/crypto trading, KYC pipelines, referral engines, and multi-gateway payment processing — and CryHub — a high-throughput event-driven platform for real-time market data ingestion, aggregation, and WebSocket fan-out, built entirely in Go with NATS JetStream and TimescaleDB.
Deeply experienced in service-layer architecture, async queue systems, JWT-based auth, and AWS S3 multi-bucket strategies for regulated financial platforms. Comfortable operating at the intersection of backend engineering and financial domain complexity — exchange mechanics, KYC/AML flows, wallet operations, and real-time price distribution.
Open to full-time remote roles with crypto-native teams. Salary in crypto accepted.

Experience
CryHub — Real-Time Cryptocurrency Market Data Platform
CryHub 2025 - 2026
Architected and built a high-throughput, event-driven microservices platform for real-time cryptocurrency market data ingestion, aggregation, and fan-out distribution at scale. Designed a 4-service pipeline (producer → NATS JetStream → aggregator → WebSocket / REST API) with a shared Go module for internal contracts. Engineered a dual connection strategy — always-on subscriptions for high-frequency streams and demand-driven lazy connections for low-frequency streams that self-terminate when subscriber count drops to zero. Built a thread-safe pub/sub hub for concurrent WebSocket client management, a 4-database Redis layout for isolated caching and rate limiting, and TimescaleDB integration via Ent ORM for time-series persistence.
