Shaikh Zaid
Full-Stack AI Systems Engineer
Summary
Full-Stack AI Systems Engineer focused on RAG pipelines, LLM agents, and cloud-native architecture — designing systems that move beyond demos into production. I've shipped TradeAgent AI (a LangGraph + Twilio + Deepgram voice agent for tradespeople), AgentAudit OS (LLM compliance observability with hash-chain audit logs spanning EU AI Act, NIST AI RMF, ISO 42001, SR 11-7 and HIPAA), and MedScribe AI (HIPAA-aware clinical SOAP notes on Deepgram + Gemini), alongside production SaaS work at Upstrapp Inc. I favour explicit state machines over open-ended LLM loops, ship production AI + SaaS for global clients, and measure work in outcomes — latency, reliability, audit trails — rather than prompt cleverness.
Experience
- Architected and shipped 5+ production features across React/Next.js front-ends.
- Built REST and GraphQL APIs with NestJS and Strapi (headless CMS), integrated with MongoDB.
- Implemented secure authentication with JWT, OAuth, and role-based access control.
- Optimized MongoDB aggregation pipelines and indexing — reduced average query response from 400ms to under 100ms.
- Containerized services with Docker and managed AWS deployments (EC2, S3, CloudFront).
- Set up CI/CD pipelines with GitHub Actions for automated testing and zero-downtime deploys.
- Collaborate in Agile sprints with daily standups and code reviews.

- Built TradeAgent AI — a LangGraph-based voice agent for tradespeople using Twilio + Deepgram, with an explicit state-graph design so every transition is logged and replayable.
- Shipped AgentAudit OS — an LLM compliance observability platform with hash-chain audit logs mapping to EU AI Act, NIST AI RMF, ISO 42001, SR 11-7, and HIPAA.
- Delivered MedScribe AI — a HIPAA-aware clinical SOAP-note generator on Deepgram + Gemini, deployed to production for healthcare clients.
- Shipped four POS variants — offline-first, subscription billing, hyper-local marketplace, and social-commerce — plus SAP-integrated invoice automation for back-office workflows.
- Productionised the freelance stack end-to-end: Next.js + FastAPI services on Docker/AWS, Stripe billing, Postgres/Redis, and observability before launch.
