πŸš€ About Me

  • πŸ›‘οΈ Currently breaking smart contracts as a Rust Security Auditor within the Rektoff <> Solana Foundation Apprenticeship (Selected top 3% from 4000+ applicants).
  • ⚑ Obsessed with Low-Latency Systems: Diving deep into hardware-level Rust by building lock-free data structures (MPMC & SPSC queues), custom spinlocks, and mastering CPU cache coherence, memory barriers, and the MESI protocol.
  • πŸŒͺ️ Turbin3 Builders Alumni, specializing in complex decentralized state machines and DeFi composability.
  • πŸ¦€ Building secure, low-latency infrastructure on Solana using Rust, Anchor, and the SVM.
  • πŸŒ‰ Building highly concurrent, async Rust backends to power trustless Web3 execution.
  • πŸ† Actively shipping in the Solana ecosystemβ€”most recently architecting StrikeBiller (a decentralized subscription engine) and PulseRaise.

πŸ“¦ Featured Proof of Work

Repository / Project Description Stack
StrikeBiller Decentralized subscription billing engine reframing Solana as a backend state-machine. Replaces Web2 cron jobs with trustless PDAs, Escrow Vaults, and an off-chain lazy-execution Cranker bot. Solana, Anchor, Next.js, Node.js
bounded-mpmc-queue A high-performance, lock-free Multi-Producer Multi-Consumer queue sustaining 63M+ ops/sec. Built to completely bypass standard OS scheduling overhead. Rust, Atomics
low-latency-rust A suite of hardware-optimized synchronization tools built from scratch. Includes a wait-free SPSC Ring Buffer and a custom Spinlock utilizing UnsafeCell, raw Atomics, and TTAS. Rust, Hardware Intrinsics
PulseRaise Decentralized crowdfunding dApp featuring dynamic platform fees and idle-capital yield generation via CPIs to Liquid Staking pools. Solana, Anchor, Next.js
PaytmNext Wallet High-throughput P2P wallet clone proving backend rigor: bank on-ramps, webhooks, and atomic financial transactions via PostgreSQL row-locking. Next.js, Express, Prisma, Docker
rust-anchor A comprehensive library of core Solana contracts. Demonstrates low-level SVM mechanics including native cross-program invocations (CPIs), complex PDA derivations, and manual account state management. Rust, Anchor, Native Solana
