Senior AI Full-Stack Engineer
Tousif Ahmed
I build AI-powered products and automation systems that actually ship. Currently leading engineering at Retreat, where we're automating the hotel RFP process for corporate teams. I also take on select freelance work for teams that need to move fast.
About
I'm a full-stack engineer specializing in AI-powered products, LLM integrations, and workflow automation. I've spent the last few years building systems that replace manual processes with intelligent automation, from hotel RFP matching engines to RAG-powered chatbots.
I care about shipping fast, writing clean code, and building things that solve real problems for real users. I've been doing this professionally for 6+ years, working remotely with US-based teams from Dhaka, Bangladesh. Currently leading engineering at a San Francisco startup.
When I'm not shipping code, I'm probably debugging my cat Isabella's latest escape attempt.
