About Me
Get to know me better
I'm a software engineer based in New York. I run Long Island City Web Solutions and work as a forward deployed engineer, building production web apps for clients with React, Next.js, and TypeScript. I graduated from Baruch College with a BBA in Computer Information Systems, and I like taking a messy idea and turning it into something people can actually use.
How I work: I care about clean code that does not fall apart after the first few features ship. I spend time on component structure, sensible data flow, and performance early so you are not fixing the foundation later. I use TypeScript, solid PR habits, and testing in the places where regressions hurt.
What I build: Most of my client work is full stack, with my strongest work on the front end. That means UI systems, accessibility, responsive layouts, and dashboards with real filters and admin workflows. Lately I have been wiring LLM features into apps for clients, chat flows, automation, that kind of thing, but only when the product needs it. I have also shipped civic tech (YourCongress won first place at a Columbia hackathon), C++ side projects, and this portfolio with a built in AI chat. Outside of client work I am usually refactoring something, learning lower level systems, or pushing one of my repos forward.

What people say about working with me
Tahmidur R.
Backend engineer at Adstradata
There was a point where we had to tighten up the way data was being passed between the interface and the backend, and Mahdi handled it with a strong mix of speed and care. He asked the right technical questions.
