I’m a backend engineer with 2+ years building and operating distributed systems, real-time data pipelines, and production infrastructure at scale. I take ownership end-to-end—from data ingestion and pipeline design to the API layer, deployment, and observability.

At NolimitNode, I shipped Rust and Python streaming pipelines over Kafka/Redpanda, built gRPC market-data services backed by Redis and ClickHouse, and helped run a Kubernetes-based microservices platform across 20–26 services at 99% uptime. I redesigned core ingestion by streaming directly from validator nodes via a custom Rust Geyser plugin, processing 7,000+ events per minute at sub-100ms latency and delivering a 10× improvement for live execution windows.

I also designed and operated distributed streaming pipelines in Rust and PyFlink for signal scoring, gating, and automated decision execution, including MEV-aware controls like slippage thresholds and frontrunning risk gating. When production load triggered cascading timeouts and in-memory cache crashes, I re-architected the query pipeline and caching strategy to restore sub-second performance and uptime.

Earlier, during a backend transition from frontend work, I designed and shipped REST APIs and relational data models for content delivery for 100,000+ users across multiple markets. Outside work, I build event-driven systems like CIForge and full-stack/blockchain products like a decentralized payroll dApp and a P2P rental marketplace—shipping end-to-end, with a strong focus on reliability and measurable outcomes.
