Over the past 10 years, I've worked with travel startups, OTA operators, and agencies to turn complex booking operations into fast, reliable, and scalable software. Whether it's a booking engine, B2B agent portal, or a full travel management system, I build solutions that are simple to run and built to handle real transaction volume: end-to-end- as a solo full-stack developer who owns the project from architecture to deployment.
