About Me
Engineer by degree,
Software engineer by practice.
I'm a Software Engineer with an Industrial Engineering background who transitioned into software development through dedicated self-learning. Over the past several years, I’ve worked on production web systems, focusing on building reliable, performant applications used by real users.
My work often involves improving existing systems rather than building from scratch. I enjoy modernizing legacy platforms, optimizing frontend performance, and improving developer experience. This includes migrating legacy Express applications to Next.js and reducing Interaction to Next Paint (INP) to under 200ms in production environments.
Beyond writing code, I care deeply about sustainable engineering practices. I’ve helped teams establish coding standards, built reusable component libraries, and mentored developers to improve code quality across projects. Recently, I’ve also been exploring AI-assisted development and how modern AI tools can enhance software engineering workflows.
