What I'm looking for

I’m interested in building high-performance, scalable applications, especially where Android development meets AI/ML. I’m also interested in tech leadership and mentoring.

At HCLTech, I built an LLM-powered automation pipeline for Medtronic’s Android 12-to-16 migration, using Langflow and OpenAI to identify deprecated APIs and generate review-ready code fixes. Previously, I developed DMAT, Verizon’s 5G/LTE field diagnostics app, and helped reduce recurring production defects by 40%.

At Infoicon Technologies, I owned and shipped three GIS Android apps for LE34, reaching 1,000+ active field users. Earlier, I helped scale Yego’s passenger apps to 1L+ downloads and a 4.7 Play Store rating. I’m expanding my AI and machine learning expertise through an MTech at BITS Pilani.
