Syed Zayn Raza

AI Engineer with 3+ years shipping production AI systems end to end, spanning LLM & RAG applications, multi-agent orchestration (LangGraph, MCP), and model fine-tuning (LoRA/QLoRA), built on robust Python backends and cloud infrastructure.

Equally strong across the stack: designing FastAPI/Django microservices, engineering retrieval and agent pipelines, and deploying scalable, observable services on AWS with Docker. I turn ambiguous product ideas into reliable, production-grade AI, from prototype to scale.

AI Engineer - AiDX Solutions - Onsite, Lahore

(2025-02)

• Architected RAG-based AI applications and MCP servers on a multi-tenant enterprise platform using LangChain and hybrid vector + BM25 search (Elasticsearch/Infinity), deployed via Docker on AWS (EC2/S3), owning features end-to-end from data model to API.
• Fine-tuned Mistral 7B using QLoRA to adapt the model to the healthcare domain, improving domain-specific relevance over the base model for production use.
• Built and deployed a stateful multi-agent system to production using LangGraph, with conditional routing, tool execution, and human-in-the-loop escalation across coordinated LLM agents.
• Designed a Model Context Protocol (MCP) server exposing ~68 LLM-invokable tools, secured with OAuth2/Auth0 and schema-validated I/O.

Software Engineer - Awesomeree - Remote, Malaysia

(2023-07 - 2025-02)

• Architected and scaled backend systems across two products from a Django/PostgreSQL foundation to FastAPI microservices handling 50K+ daily requests, driving a 45–50% reduction in API response times through Redis caching, query optimization, and database indexing.
• Shipped a production AI voice assistant (OpenAI Whisper) achieving 92% transcription accuracy across 5+ languages, with real-time WebSocket streaming at sub-200ms latency using async Python, integrated end-to-end within a cross-functional remote Agile team.
• Containerized services on Docker + AWS EC2 and built CI/CD pipelines that reduced deploy time from 2 hours to 15 minutes; established team-wide coding standards, API documentation, and deployment procedures maintaining 99%+ uptime across 8+ feature releases.
