About Me 🔗

Hi 👋

I am Haseeb Annadamban. I am a software engineer from Kerala, India.

Currently, I am a freelance Rails developer. I have spent a fair amount of time building Rails apps since 2016. I have successfully delivered numerous projects, ranging from MVPs to complex systems serving millions of users. My specialization includes performance tuning, AI integrations, and product leadership. I am known for being self-driven and easy to manage. My clients are mostly from USA. But I had clients from Australia and India too.
