Hi, my name is
I design and scale distributed backends, agentic systems, and cloud infrastructure in Go, TypeScript, and Python. Recently led a TypeScript to Go migration that cut infrastructure cost by more than 75% while increasing throughput. Founder & CTO at Heurista.io.
I'm a Senior Software Engineer with 5+ years designing, building, and scaling distributed backend systems, agentic systems, and cloud infrastructure. AWS certified, with deep hands-on work in Go, Node.js/TypeScript, Python, and .NET across microservices, event-driven architectures, and REST/GraphQL APIs.
As Founder & CTO at Heurista.io (July 2022 – Present), I own architecture and cloud direction for products including ShuttleBook and SocialBay. At CueGrowth I recently led a TypeScript to Go migration that cut infrastructure cost by more than 75% while increasing campaign throughput.
Recognized for technical leadership, time management, and delivering both independently and with distributed teams.
