About

Pawan Danani out on the water
Stony Brook UniversityB.S. Computer ScienceB.S. Economics · 2021

Hi — I'm Pawan, a software engineer based in New York. I studied Computer Science and Economics at Stony Brook University, and I've spent the years since building software people lean on every day: retail point-of-sale platforms, geospatial analysis tools, internal AI assistants.

Outside of work I'm usually hunting down a new restaurant somewhere in New York (I've tried like a million). When I'm not eating my way through the city, I'm biking, hiking, catching up on the latest movies, or adding to an ever-growing keyboard collection.

Experience

  1. Software Engineer · M&C Saatchi World Services

    Dec 2025 — Present · New York, NY

    I build geospatial analysis and data tools here.

  2. Software Engineer · P.C. Richard & Son

    Aug 2023 — Dec 2025 · Long Island, NY

    I got to touch nearly every corner of retail tech here: modernizing a legacy IBM i point-of-sale into a React web app that 2,000+ employees use daily, building the Java companion app that turned tablets in 70 stores into tap-to-pay terminals, and shipping an internal AI assistant that cut IT and HR tickets by 15%. Along the way I replaced legacy manual late night deployment processes with modern Jenkins pipelines, hardened the middleware APIs, and kept the employee mobile app humming for 3,000+ users.

  3. Software Engineer · Envogue International (madeyn.com)

    Mar 2022 — Oct 2022 · New York, NY

    A proper startup sprint: I built the Explore, Profile, and Home pages of madeyn.com, a social e-commerce app, and wired up the AWS underneath it: Cognito auth, Lambda triggers syncing users into Postgres, and media compression that cut page weight by 60%.
