WHO I AM

ABOUT ME

I'm a full-stack software engineer with over 7 years of experience building scalable, user-centric software primarily in fintech and financial data products. I combine engineering best practices, product thinking and design sensibility in every project I work on.

With a background in graphic design and UI/UX, I'm able to take a product from concept to implementation without losing the user experience along the way. My foundation in business economics means I understand not just the code, but the business context behind every feature.

Most recently I've served as the sole technical decision-maker for a production platform with more than 2000 users, collaborating directly with C-suite to define product roadmap and translate business needs into reliable, high-quality software.
