Hello! I'm Sagar,
I'm a senior web developer with 5+ years of experience in building secure, high-performance, and scalable applications that consistently improve product reliability, speed, and business growth. Currently based in the Amsterdam Area, I work at the AMOLF Institute (Science Park), where I collaborate closely with researchers to develop software tools that support scientific research. In every project, my goal is to deliver code that's clean, efficient, and built to last.
