What I'm looking for

I seek senior engineering roles building scalable, secure cloud-native systems with strong CI/CD, observability, mentoring opportunities, and collaborative product teams.

I am a seasoned Senior Full-Stack Engineer with 10+ years designing and implementing scalable, secure, performance-driven web applications using React, Node.js, TypeScript, and Python (Flask/Django). I build serverless and microservices architectures on AWS/GCP, optimize databases with Sequelize and TypeORM, and drive CI/CD automation with Docker and GitHub Actions.

I mentor junior developers and lead architecture discussions, delivering measurable results such as reduced downtime, faster deployments, and improved performance. I focus on observability, testing (TDD), and cross-functional collaboration to ensure high-quality, production-ready systems.
