At SNOW SOFTWARE (ACQUIRED BY FLEXERA), I delivered data-intensive product features from technical planning through implementation, testing, deployment, and production support. I built Node.js and TypeScript services for request orchestration, background processing, and real-time updates.

At FIVE9, I designed Java and Spring Boot services and created 16 versioned REST endpoints for operational workflows. Earlier, at AGILE TECH, I built Angular and React features and improved response times by 45% on catalog and administration screens.
