Hi, I'm Varit, a Senior Frontend Developer passionate about technology, leadership, and people. I started coding 12 years ago simply because I loved solving problems. I still love it, but I’ve learned something important along the way: technology is about people first. Today, as a Senior Frontend Developer at Kalido, I lead two agile teams, helping engineers craft robust, reusable frontend solutions using JavaScript, VueJS, React, Angular, NodeJS, and GoLang. By collaborating closely with product managers and designers, I've realized the real satisfaction lies in building teams that genuinely care about what they create. Beyond work, mentoring junior developers through ADPList and engaging with the broader developer community on Stack Overflow keep me inspired. Sharing knowledge, I've discovered, is just as fulfilling as acquiring it. I’m always up for conversations around frontend tech, team-building strategies, or simply exchanging ideas about navigating life as a developer. Feel free to connect :)
