Hi, I’m Rahul Dev 👋

I’m a Full stack developer currently working on RPC, Solana validator internals, and async Rust.

Current Focus

  • Studying Agave (Solana validator) internals
  • Building an RPC sidecar MVP to reduce validator contention
  • Exploring:
    • mmap & shared-memory IPC
    • lock-free / wait-free data paths
    • async Rust (Tokio)
    • jsonrpsee-based RPC servers
    • safety boundaries in unsafe Rust

Projects

🔹 Solana RPC Sidecar (WIP)

Goal: Decouple read-heavy RPC traffic from the validator replay loop

Tech: Rust · mmap · shared memory · lock-free queues · jsonrpsee

Highlights

  • Validator publishes read-only state observations
  • Sidecar serves RPC without blocking consensus or replay
  • Explicit safety invariants around shared memory
  • Benchmarks comparing in-process vs sidecar RPC

📂 Repo: https://github.com/rahuldev7583/agave-sidecar-ipc

🔹 Solana Client Apps & Anchor Programs

  • Built multiple Solana client-side applications
  • Experience with Anchor programs and account models
  • understanding of Solana runtime from a dApp perspective

✍️ Writing

I write technical deep dives on Solana & Rust infrastructure:

  • RPC request flow inside Agave
