About
Muhammad Waleed Zia

AI systems engineering, end to end.

I'm a Senior Full Stack Developer and AI Engineer with 5+ years building web platforms and AI systems for startups and enterprises, having led 10+ products from conception to deployment. Most recently, I've been building LLM evaluation pipelines that route across multiple providers and content modalities in production.

I care about shipping systems that hold up in production: clean APIs, sane data models, and infrastructure that scales without drama. Based in Lahore, Pakistan, working remote with teams worldwide.

Operating Profile — one engineer across model, API, and interface

AI Systems & Evaluation

Architected an internal LLM evaluation platform running high-volume async evaluations, with a 2-stage pipeline pairing parallel primary evaluators against meta-evaluator aggregation. Built multi-modal RAG pipelines (text, documents, images, audio, video) with LangChain and LangGraph, routing and failing over across 4 LLM providers — OpenAI, Anthropic, Google, and Fireworks.

Full-Stack Engineering

10+ products shipped end to end: React/TypeScript front ends backed by Python and Node.js services — FastAPI, Express, Nest.js — on PostgreSQL, MongoDB, and Redis. Comfortable owning a feature from data model to deployed UI.

Infrastructure & Reliability

Real-time streaming over WebRTC/WebSockets with GCP Pub/Sub, containerized with Docker and Kubernetes, deployed via Helm and CI/CD. Consolidated region-by-region API scans into a single aggregated call to cut operational overhead.

Full Stack AI Engineer

  • Architected an internal LLM evaluation platform (FastAPI, Celery, Redis, MySQL) executing high-volume asynchronous evaluations, with a React/TypeScript operations dashboard for configuration, monitoring, and analytics.
  • Designed a 2-stage evaluation pipeline pairing parallel primary evaluators with meta-evaluator aggregation, deepening evaluation quality without sacrificing throughput.
  • Built RAG-enabled evaluation pipelines spanning 5 content modalities (text, documents, images, audio, video) with LangChain and LangGraph, with routing and failover across 4 LLM providers (OpenAI, Anthropic, Google, Fireworks).
  • Engineered real-time streaming (GCP Pub/Sub, WebRTC, WebSockets, Selkies/GStreamer, STUN/TURN) with VM-level authentication; cut VM-cleanup API overhead by consolidating region-by-region scans into a single aggregated Compute Engine API call, deployed via Helm.
