Senior Full-Stack Web Software Engineer
Farhan is a highly reliable full-stack engineer with strong product judgment. He consistently delivers clean, production-ready work and takes real ownership of what he builds. He communicates clearly, flags issues early, and handles ambiguity well. I trust him with core parts of the product and would happily work with him again on complex, long-term projects.

React Application refactor
We had a very positive experience working with Muhammad. He headed up the complete redevelopment from the ground up of our 5 year old React application. From putting in place all of the structure, to migrating the legacy code base and then adding the additional new testing framework to build from.

What I actually build:
→ RAG pipelines with vector search (Pinecone, pgvector), custom embeddings, chunking strategies, and hybrid retrieval
→ Autonomous AI agents, tool-calling, multi-step workflows, LangChain/LangGraph orchestration
→ LLM-powered features using OpenAI, Claude, and Gemini, structured outputs, streaming, prompt engineering
→ Voice AI systems, real-time speech processing, conversational agents, automated operations
→ Full-stack product development: Next.js, React Native, Node.js, Python, PostgreSQL, AWS
Recent work that shows the range:
Aura Health: Built an AI health companion with LLM orchestration across mobile, desktop, and ChatGPT. 8M+ active users.
Sonea.ai: Voice AI agents for logistics. Real-time speech processing, autonomous order management, invoice generation. Zero manual intervention.
Navero : AI-driven recruitment platform. Automated screening, interview scheduling, candidate analytics. Cut hiring cycles from months to weeks.
Keller Williams: Modernized a legacy real estate platform across 35 countries. $4.5B in transaction volume.
TryHackMe: Rebuilt core architecture for scale. Went from 2M to 6M users with zero performance degradation.
Good fit if:
- You're building an AI product, chatbot, RAG system, AI agent, LLM features and need it production-ready.
- You have an existing app and want to add AI capabilities (intelligent search, document Q&A, workflow automation).
- You need an MVP shipped fast by someone who understands product, not just code
- You want clear communication, daily updates, and no surprises.
I work US timezone hours. Async updates via Loom + daily standups. Clean code, tested, documented.
Message me with your project details. I typically respond in a few hours and scope most projects within a day.
