6+ Years Experience
February 2019 - Present
I’ve been coding since 2019, building web apps with Angular, React, and Vue, plus mobile apps with Flutter. Over time I drifted deeper into the workflow side — CI/CD, automated tests, AI-powered PR reviews, code-quality gates, GitHub Actions, and small automations that glue everything together. It’s the kind of plumbing that keeps deploys predictable and speeds up the whole team. I’m self-taught and still experimenting with AI to make development faster without sacrificing quality.
