30 minute consultation
Umair delivered an exceptional Product Requirements Document (PRD) for our MVP project. His understanding of the technical architecture, feature scope, and multi-AI integration was spot on. I look forward to moving forward with him on the project.

Full stack developer - React / React Native / Node / AWS / Micro services
Umair has been very helpful in building our project. He is constantly proactive and understands the job very well. His technical expertise makes it easy for us to explain our requirements in simple language and see our expected results become true. I would surely work again with Umair, and in fact, I am at the moment!

$400K+ earned on Upwork · 100% Job Success · 14,000+ billable hours · Top Rated Plus (Top 3%)
Available in US Eastern business hours so your 9 AM meetings work perfectly.
✅ Production AI I've shipped:
1. RAG pipelines with vector retrieval, re-ranking, and eval harnesses
2. Multi-step AI agents using LangChain, LangGraph, and custom orchestration
3. OpenAI, Claude, and Gemini integrations with model-agnostic fallbacks
4. Voice AI with ElevenLabs, MCP servers, Google Agentspace, A2A
5. Token cost controls, prompt-injection guardrails, hallucination monitoring
✅ Best fit if you're thinking:
1. "My OpenAI bill is spiraling and I need it controlled without losing quality."
2. "My RAG retrieval returns irrelevant chunks. The answers are wrong."
3. "My AI agent loops, times out, or breaks on edge cases."
4. "I need to move from prototype to production but don't know how to scale LLM calls."
5. "I want to swap models (OpenAI, Claude, Gemini) without rewriting my stack."
6. "I need evals and monitoring, not vibes-based testing."
✅ Stack:
GenAI: LangChain, LangGraph, LlamaIndex, OpenAI, Anthropic, ElevenLabs, MCP, A2A, Google Agentspace
Backend: Python (FastAPI, Flask, Django), Node.js, .NET Core
Frontend: React, Next.js, Angular
Cloud: AWS (Lambda, API Gateway, ECS, Step Functions, RDS), Docker
Data: PostgreSQL, MongoDB, DynamoDB, Pinecone, Weaviate, PGVector
✅ SaaS products I've built or contributed to (10k+ active users):
C60 AI (LLM-driven product features), Pabau (full-stack plus AI features), Lingvano, OpenTherapy, NurseIO
✅ What working with me looks like:
1. Token cost and latency projections before we build
2. Evaluation harness for retrieval accuracy and response quality
3. Model-agnostic architecture so you can swap providers
4. Guardrails against prompt injection, hallucination, and runaway costs
5. Production monitoring (cost, latency, quality) from day one
