What I'm looking for

I’m looking to build real-time, agentic AI and backend systems—shipping scalable APIs and voice/event-driven pipelines with LLMs and multimodal capabilities. I want ownership, fast iteration, and production-quality deployments with strong observability.

I’m an AI and Backend Developer with a background in ECE, specializing in building real-time, agentic systems. I focus on production-ready architectures—scalable APIs, hybrid memory designs, and event-driven AI pipelines—so models actually work in the real world.

In recent roles, I shipped production AI voice agents handling 500–600 calls/day for a single client, covering inbound qualification, outbound follow-ups, call transfers, and human handoff logic across SIP/Asterisk/FreePBX stacks. I also engineered large-scale call-log pipelines (over 1M records) with Whisper transcription, PII sanitization, and multi-agent performance analysis, and built real-time outbound voice agents orchestrated through custom FastAPI control planes.

I enjoy tackling hard infrastructure gaps—like SIP trunking integration and low-latency non-English turn detection for voice agents—by designing robust telephony middleware and deployment workflows. I’m equally motivated by building multi-agent products (from cafe analytics to pitch-deck generation) with strong observability, async performance, and structured output validation.
