me in a park in Boston

Hi! I’m Aldrin, an engineer living in Manhattan. I build and work with AI agents.

What I do

I work at Athena Intelligence, an AI company in Manhattan. We build AI agents that do real analyst work inside big companies: pulling data together, running the analysis, writing it up. I joined in mid-2024, when it was just our CEO and two other people. My title is Forward Deployed Engineer, which in practice means two things. I build a lot of the product (most things you see in our app, I’ve probably touched), and then I go make it work for the people actually using it, sometimes on-site with customers in New York and London.

Before Athena, I was on the GenAI team at Thoughtworks in India and worked on the AI side of Voicenotes, a YC startup. I studied computer science at Model Engineering College in Kerala and graduated with Honours in Machine Learning.

Some things I’m proud of

More on the Highlights page, and the things I’ve built are under Projects.

Outside work

I’m into music. I’ve played guitar since high school, mostly for myself, working out songs and melodies by ear. In college I played in our college bands at arts festivals, and I whistle too. A few recordings I like are on the Music page.

I also did drama in college, and one Easter in New York I played Jesus in a Living Stations of the Cross performance at St. Paul the Apostle Church, which is not something I expected to ever write on a website.

I dance salsa too, something I picked up after moving to New York.

I also travel whenever I can. Some favorites so far: Yosemite, the Grand Canyon, New Orleans, Vegas, a winter trip through Amsterdam, Berlin, Barcelona, Rome and Venice, and London and Edinburgh. I write some of those up under Travel.

And I still like tinkering. Small weekend things like NYCGuessr or teaching myself chords with a $64 MIDI keyboard.

Say hi

  1. MIDI Piano Playground — teaching myself chords with a $64 keyboard and Claude Code

    A $64 Casio, a MIDI cable, and a weekend of coding: a Swift CoreMIDI recorder, a key-detection analyzer (Krumhansl-Schmuckler + Viterbi), a browser practice app that grades my left-hand chords live over Web MIDI, and an ffmpeg + Demucs pipeline that turns the real song into a play-along backing track.
  2. A solo weekend in New Orleans

    Three days alone in New Orleans — the French Quarter and its tangled French-Spanish-American history, a swamp full of alligators, Preservation Hall jazz, a streetcar to the Garden District, and the National WWII Museum, which turned out to be the best thing I did all weekend. Plus all the food, and practical notes for anyone planning their own trip.
