Message

At RelationalAI, I built and led the Performance SLO framework, defining and tracking 20+ SLOs and bringing performance reviews into engineering design and delivery. My work helped reduce cold-start latency by ~98%.

I founded and built RelationalAI’s cost management function, driving a 70% reduction in infrastructure COGS within three months. I also scaled cost management across Snowflake and Azure, 10+ global regions, and 20+ teams, delivering $100K+ in additional monthly savings.

In Control Plane Engineering, I built and maintained the Go control plane for a distributed knowledge graph database running on Kubernetes. I designed an asynchronous transaction protocol and improved transaction processing performance by 50%.

Earlier, at ProGineer Technologies, I developed C/C++ backend systems for the Exensio Analytics Platform and ported Oracle/Informix tools to Cassandra, improving time and memory performance by 10x. At Asal Technologies, I worked on Salesforce APEX development and administration.
