About Me

Get to know me better

Who I am

Frontend Engineer building enterprise-grade web applications with a strong focus on scalable architectures and complex user interfaces.

What I do

I work with React and Angular on large, real-world systems, often in monorepo environments. My focus is on frontend architecture, state management, reusable UI components, and the integration of complex APIs.

How I work

I value clean, maintainable code and predictable systems. My background in legal and management roles influences my engineering mindset: structured thinking, responsibility, and long-term sustainability over quick wins.

What I care about

I’m passionate about digital transformation — replacing inefficient, fragmented processes with modern, maintainable software that delivers real business value.
