DevOps · CI/CD Pipelines · Ethereum Infrastructure
SiddarthKumar.
I build and maintain the infrastructure behind decentralized software: CI/CD pipelines, multi-platform build systems, and Ethereum validator nodes. Currently at IFT, previously shipping across mobile, desktop, and blockchain.
The work,
plainly
stated.
"Get it working first. Make it good later. Momentum matters more than perfection."
Toolchain
At IFT, I look after production deployments and on-call for Ethereum light client infrastructure. Nix derivations, nftables firewall migrations, benchmarking nimbus-eth1, keeping CI green when Apple ships a new Xcode. The kind of work that's invisible when it runs well and very visible when it doesn't.
Before this I was at Status, where I took on the React Native 0.63 to 0.73 upgrade that nobody wanted to touch. I also owned the build systems across iOS, Android, macOS, Linux, and Windows. Jenkins pipelines, reproducible Docker environments, Nix for dependencies, Fastlane for releases.
I started out as the first engineer at a small consultancy and ended up running it as CTO. Grew the team to 30, shipped Laravel sites and React Native apps, set up our first CI pipelines. I believe in reproducible builds, open-source tooling, and doing things properly rather than quickly.

Notes on build systems, Ethereum infrastructure, and the occasional debugging rabbit hole. Written when something is worth writing down.

is limited.
I'm currently heads-down on a few things. Book a slot and I'll review it. No guarantees, but I do read every request.

If something I've built or written saved you time, you can keep the lights on.
