About Me
I'm a product-oriented Frontend Developer with over 10 years of experience crafting user-centric, performant web applications. My background includes working across industries, leading teams, and collaborating closely with design and product to deliver meaningful user experiences. I specialize in building interfaces with React and Next.js, and I'm always focused on shipping products that not only work — but feel great to use. As the tech landscape shifts, I'm embracing tools like generative AI to enhance my workflow, speed up prototyping, and explore new ways to build smarter, more adaptive frontends.
What I bring to the table:
- •Strong UX instincts and product thinking
- •Clean, maintainable code with performance in mind
- •Leadership experience in cross-functional teams
- •Curiosity and adaptability to keep up with change
- •Looking to join a team where quality, ownership, and real-world impact matter
