What I'm looking for

I'm targeting senior engineering roles with product companies in Mumbai, Navi Mumbai, Thane, Pune, or fully remote. I'm available for immediate joining and open to hybrid arrangements.

At Quantinsti, I developed APIs and data pipelines for the Quantra LMS, serving learners across more than 150 countries. I engineered Redis-based webhook processing that prevented data loss during peak traffic, and built enrollment flows that reduced processing errors by 90%.

I also integrated Claude and OpenAI endpoints into production features, reducing manual QA cycles by 40%. Earlier, at Chien Technologies, I shipped DoggieTheApp and Vetolution from zero to production, and at Justdial I developed financial reporting modules and Python automation.
