At Slaab AI, I architected and built BotSlaab, an AI-powered voice and chat agent platform. I developed real-time WebRTC and WebSocket voice pipelines and built agent workflows for context-aware conversations and knowledge retrieval.

I also built USRI, a production-grade AI outbound calling platform for sales and appointment automation, with campaign management, call analysis, calendar booking, and multi-tenant access controls. Earlier, I developed and maintained a Flutter e-commerce app at OneKnotOne Technologies.
