Backend-leaning full-stack engineer. I build distributed systems that stay boring under load — event pipelines, APIs, and the infrastructure that keeps them honest. Currently scaling payments at a Series C fintech.

About
I started writing code to automate my college attendance spreadsheet and never really stopped automating things. Over eight years I've moved from scrappy startup monoliths to designing systems that process millions of transactions a day. I care most about observability, clear failure modes, and APIs that are a pleasure to integrate against. When a system is well-designed, on-call gets quiet — that quiet is the goal.

Words
“Arjun is the engineer other engineers escalate to. He left our payments stack more reliable and far easier to reason about.”
“His PRs to our OSS project were the cleanest we've reviewed — tests, docs, and a design note every time.”
