Hi there 👋🏻 I'm Raihan, a generative AI engineer in Kolkata.
By day I'm a Member of Technical Staff at Graphify Labs (YC S26), where we turn codebases into a knowledge graph that AI coding assistants can query, trace and cite. On nights and weekends I'm building ColdVisit, an agent that opens a real browser and tests your critical user journeys on every pull request.
I like the part of the job where an ambitious idea turns into something people can actually use: a scrappy MVP this week, a real AI product the next. Before Graphify I was a GenAI developer consultant at eSynergy, shipping for clients like HSBC, Defra, AWS and Marsh McLennan, and an AI protocol engineer at Layer-E, where I built Polygon Copilot and Mantle Buddy.
I'm also the lead organiser of diversion.tech, the largest hackathon in Eastern India, and I write now and then on Substack. I co-wrote a paper on security threats in agentic AI systems.
Away from the keyboard, I'm usually traveling and turning moments into short cinematic clips. The passport on this site is where those trips live, and you can turn any of my photos into a postcard for me that lives on my website forever.
Let's build something transformative.
