My OSS Journey
Contributing to open source has shaped how I write software, think about APIs, and collaborate at scale. Here's the story — with live numbers straight from GitHub.

Journey
- Jan 2026
Cut my first PyTorch Lightning release
Owned a release of the core framework end to end — Lightning v2.6.1.
PyTorch Lightning v2.6.1 release notes - Dec 2025
50th commit to PyTorch Lightning
Hit 50 commits to PyTorch Lightning itself — the framework that started it all for me.
- Oct 2025
100th commit to LitData
Crossed 100 commits to LitData — by now my home base in the ecosystem, from streaming datasets to releases.
- Feb 2025
Became a Tier 2 OSS Contributor at Lightning AI
Recognized as a Tier 2 OSS Contributor — the result of a year of steady work across LitData, LitServe, and the wider ecosystem.

Joined the LitData core team
Invited onto the core team after a few months of contributions — a small group of maintainers shaping where the library goes next.
“I want to welcome Bhimraj Yadav to the LitData core-team. He made some splendid contributions to LitData in the past months and we are quite eager to see what comes next 😉”

First PR to LitData
Started with just a one-line change — the beginning of what became my most active corner of the ecosystem.
LitData #169 - May 2024
First PR to the Lightning ecosystem — LitServe
My first contribution to a Lightning AI repo. It merged a couple of days later, with a few words from the founders that I still keep around.
LitServe #113“Let's goo! Merged 🚀”
“congrats @bhimrazy! solid contribution”
- Mar 2024
Published my first Lightning Studio
My first public artifact in the Lightning AI ecosystem — and the spark that pulled me toward contributing upstream.
View the announcement - Mar 2024
Joined the Lightning AI Studios Publisher Program
Invited into the Publisher Program to collaborate with the team and build Studios — my first foothold in the Lightning AI ecosystem.
“We're excited for you to collaborate with us and build some great Studios.”
