01/About

I build end-to-end data systems on Databricks, Snowflake, and AWS. Before that, I was building full-stack apps — and that experience still shapes how I think about data. For me, it's not just about pipelines, but how the data flows all the way to the end user.

The Journey

'19

Intern

atAntStack

Started the journey — barely knew React, eager to learn everything.

'20

Web Developer

atAntStack

Full-stack development with Hasura, Azure Functions, Next.js. Built ecommerce platforms and internal tools.

'23

Solutions Architect

atAntStack

Shifted to data engineering while keeping full-stack roots. AWS CDK, AppSync, and first Databricks projects.

Recent

Principal Architect

atAntStack

Leading data engineering initiatives. Databricks, PySpark, building pipelines that process millions of records.

05/Beyond Code

Books

Books

96 books on Goodreads and counting. Brandon Sanderson's Cosmere universe has most of my attention — intricate magic systems, interconnected worlds, the kind of world-building that rewards re-reads. Stormlight Archive is my happy place, for all its chaos. Robert Jordan's Wheel of Time is up there too (Mat Cauthon is the best character, fight me). Also: Harry Potter (always), Dan Brown's thrillers, and whatever catches my eye next.

Goodreads Profile
Music

Music

My Spotify is a mess in the best way — Malayalam film soundtracks, country music, Romanian pop, Lana Del Rey, Avicii, Irish folk, and whatever else I stumbled into that week. Yes, country. Luke Bryan, Johnny Cash, the whole Forever My Girl soundtrack. Songs across languages I don't even speak. I follow the music, not the genre.

Spotify Profile
Cooking

Cooking

Experimental. Whatever catches my eye on Instagram gets tried. No cuisine loyalty, no meal prep discipline — just curiosity and a reasonably stocked kitchen.

Long Walks

Long Walks

Usually with an audiobook or music. Sometimes a podcast. The walking part isn't a cameo — it's how I think through problems or stop thinking about them entirely.

Curiosity

Curiosity

StarTalk Radio is my background noise of choice. Astrophysics, AI, black holes, the occasional argument about time travel. Neil deGrasse Tyson makes it all surprisingly easy to get going down the rabbit hole.

StarTalk
Linux

Linux

Seven-plus years of daily driving Linux — Manjaro first, now CachyOS. Work, personal, everything. There's something satisfying about an OS that lets you break things and fix them on your own terms.

06/What's Next?

Let's build something together.

I'm always up for conversations about data engineering, distributed systems, or building things that work at scale. Also happy to talk about Sanderson theories, music recommendations, or whatever else.
