@himanshurai4

SDE-1 (AI/ML) at Adda247, building Gemini-powered audit systems that raised call-audit accuracy from 65% to 95%+.

At Adda247, I built Antrik, an AI call-intelligence platform processing sales and support calls, and engineered its Gemini audit architecture, improving accuracy from 65% to 95%+ while reducing per-audit cost by 58%.

I also architected Karma, an analytics and performance-management platform, and built LLM class-audit and campaign-generation systems. Earlier, as an AI Intern at Adda247, I built a template-intelligence platform and automated Telegram content distribution.
