I build intelligent systems—and spend an unreasonable amount of time thinking about how to make them consume, process, and make sense of data.

By day, I’m usually somewhere between system architecture, AI, data, and figuring out why something that should work absolutely refuses to.

When I’m not building things, there’s a good chance I’m watching football. I’ve been a Mohun Bagan supporter for 19 years—long enough for the club to become less of a football team and more of a permanent emotional condition. Somewhere along the way, I also fell hopelessly in love with Arsenal, back when Arsène Wenger was pulling the strings and football still felt a little more romantic.

And then there’s Spotify.

My earphones are less of an accessory and more of a life-support system. There is a fairly high correlation between my productivity, sanity, and whether Spotify is currently playing something.

So, in short — I build intelligent systems, obsess over architecture, overthink football, and require a suspicious amount of music to function.

→ Welcome to my little corner of the internet.

A.P. Moller — Maersk

Bengaluru, IN · Proprietary

Associate Software Engineer

  • 30+ PySpark pipelines on Databricks Delta Lake move 12M+ shipping records a day out of 30+ terminals and into the tables freight analytics reads from. Reworking the ingestion path took end-to-end latency down by 70%.
  • Moved 40+ API credentials into MSS Vault across the CDT, PP, and Prod environments, and cleared the container-tracking data-quality defects that were feeding bad state downstream.

Software Engineer Intern

  • Three production REST APIs (OpenAPI 3.0.1) sit behind StarGate and Apigee for the Digital Maritime and PO Invoice teams — 50K+ requests a day at sub-100ms P95.
  • An event-driven PostgreSQL → Delta Lake sync keeps rate data current in real time, holding 99.7% consistency across the systems it spans.
