What I'm looking for

I seek senior engineering roles building cloud-native, data-intensive platforms with strong engineering practices, mentoring opportunities, and collaborative Agile teams.

I am a senior full-stack software engineer with 10+ years building scalable, high-performance applications across energy analytics, safety management, IoT, and enterprise solutions. I design intuitive frontends with React, TypeScript, and Angular, implement robust backends with Java Spring Boot and Node.js, and deploy cloud-native systems on AWS with CI/CD automation.

I've delivered platforms processing millions of daily data points, reduced processing times by up to 65%, achieved 87% test coverage, and supported thousands of concurrent users with 99.9% uptime. I mentor junior engineers, partner with cross-functional teams, and drive production-quality solutions in Agile environments.
