What I'm looking for

I seek senior engineering roles where I can lead secure, scalable TypeScript/full-stack and serverless projects, mentor teams, and improve CI/CD and SSDLC practices.

I am a Senior Full Stack Engineer with 11 years of experience building secure, high-performance web applications using TypeScript, Angular, Node.js, and serverless architectures like Firebase and AWS Lambda. I have a strong track record implementing SSDLC and threat modeling practices that materially reduced vulnerabilities and improved deployment efficiency across distributed international teams.

My work has delivered measurable results: faster front-end load times, significantly reduced server response times, and robust NoSQL data models supporting high-volume usage. I collaborate effectively in Agile environments, mentor junior engineers on security and best practices, and drive CI/CD, GitHub-based workflows, and automated pipelines to accelerate feature delivery.
