I've built high-scale backend and AI systems at Bolster AI, Convonest, Zee5, Cisco Webex, and Reliance Retail. At Bolster AI, I automate phishing takedown workflows and replaced GPT-based email classification with an in-house DeBERTa v3 model.

I’ve delivered Flink pipelines handling 300K+ events per second, ad decisioning for 8M+ monthly users, and an AI SaaS platform with 93% email-classification accuracy. I also lead engineers, mentor junior developers, support technical hiring, and advise on acquisition due diligence.
