About Me
AM I'm a full-stack engineer with 4+ years of experience building data platforms and backend systems. My work spans event-driven architectures, cloud deployments, and integrating AI capabilities into production applications.
Currently at OpenQ Labs, I work on developer analytics (designing Kafka pipelines, building synchronization services in Go and TypeScript, and deploying microservices on Kubernetes). Before that, I built enterprise data platforms integrating Snowflake and Fivetran, and automation systems at a robotics company.
I care about systems that actually work at scale: clean architectures, proper observability, and code that the next person can understand. When I'm not coding, I start my day with coffee and fresh air, small rituals that keep me grounded while the AI landscape changes faster than my npm dependencies.
