About

I build AI systems that talk, think, and ship to production. Over the past 4+ years, I've gone from writing mobile apps to architecting full AI-powered products, an IVR voice agent that handles 200+ real phone calls a day, a no-code platform where enterprises build their own AI agents, and a live streaming pipeline that gets camera feeds to mobile screens in 16 seconds flat. I care about systems that are modular, scalable, and actually work under load.

Architected an enterprise AI Agent Platform (no-code) — designed microservices backend with RAG pipelines, multi-provider LLM orchestration, MCP-based tool execution, async document ingestion, and real-time streaming chat layer.
Built an IVR Voice Agent from scratch in Go — pipelining Deepgram STT, LLM inference, and TTS over concurrent WebSocket streams with goroutine-based turn management. Handles 200+ live calls/day with sub-second latency.
Designed a zero-downtime live streaming pipeline using AWS MediaConnect + MediaLive — auto-provisioning dedicated infra per stream, converting raw camera feeds to mobile-optimized 9:16 format in 16 seconds.
Earlier role focused on building cross-platform mobile apps with Flutter and Dart, contributing to multiple client-shipped products.
