Hi I’m Robin.

I’m a Software Developer with around 4 years of experience in designing and building scalable backend APIs, efficient SQL databases, seamless UIs and more recently, real-time communication systems where uptime, availability and performance are extremely critical.

I lead the tech team at FreJun, one of the fastest growing cloud communications firms in India (currently doing 500k+ business calls/day). My day-to-day responsibilities include product discussions, system design, development, documentation and team management.

Being an obsessive learner and problem-solver, I believe my skills are not tied to any specific set of technologies and that using the right tool for the job is the way to go.

I’m always on the lookout for exciting problems to work on. Please feel free to get in touch with me at [email protected]
