I met Waqas while working with another firm. We did a bake-off and his squad demolished the the other team. Unfortunately his team was not selected to do the project, it has been 7 months and the project is still not done! Well, their loss was my gain. Every since, I have been working with Waqas and his group and it has been amazing. A true partner to the point that I view him as a key partner in everything that I do. Highly skilled and patience even when I get super busy and sometimes not as responsive due to workload. I would recommend him without a doubt. Brilliant mind!

I help you design and implement production-ready AI systems using OpenAI, LangChain, and full-stack architecture.
Most teams I work with are dealing with disconnected tools, manual processes, or early-stage AI ideas that don’t translate into usable products. I turn those into structured, scalable systems with clean architecture and reliable outputs.
