I'm a Senior JavaScript Engineer with 10+ years of experience building scalable, user-friendly web applications.

Throughout my career, I've worked in diverse environments — from launching MVPs in small start-ups to modernizing legacy codebases in companies with over 1,000 employees. I enjoy mentoring and have helped over 10 junior developers grow into their roles, while also contributing to hiring processes and team building.
