open for work

Hi, I'm Jayakrishna

you can call me JK

Solana · Rust · Infra & Tooling

systems-focused developer from India building on Solana. i work primarily in Rust and TypeScript, writing protocol-level programs, async backend services, and infrastructure tooling.

i'm drawn to the lower layers, async runtimes, QUIC internals, gossip protocols, and how distributed systems coordinate under real constraints. i read source, trace execution paths, and study runtime behavior until i understand things end-to-end.

i've shipped production Anchor programs, contributed to open-source across the Solana ecosystem, and built infra projects like on-chain indexers and gossip network explorers. currently building s0nar.online.

I mostly work with these
