What I'm looking for

I’m looking to build end-to-end AI-enabled products—trusted ML workflows, governance-minded systems, and voice/retrieval experiences—where I can own production engineering, observability, and CI/CD, and collaborate closely with security and platform teams.

I’m an AI and full-stack software engineer with 8+ years of experience building production software platforms spanning AI applications, ML platforms, network intelligence, cloud infrastructure, and research-driven computer vision. At Comcast, I built AI-enabled internal engineering and security applications around Project GuardRail, including intake-to-approval workflows, audit trails, and risk assessment using React, Next.js, FastAPI, GraphQL, and PostgreSQL/Redis.

I also integrated Azure OpenAI GPT-4o for summarization, classification, and structured extraction with JSON schema validation and fallback handling, and I built an internal AI voice agent using Twilio Voice, Deepgram STT, Azure Speech TTS, FastAPI, WebSockets, and OpenSearch for retrieval-grounded, conversational answers and escalation flows. Previously, I led AMP’s ML platform work, orchestrating model training and batch inference with Airflow/Spark/Kafka and tracking experiments with MLflow—backed by strong observability, RBAC, PII-safe logging, and CI/CD ownership.
