Solana Blockchain Engineer
Hi, I'm a software Engineer with experience leading backend architecture, distributed systems, blockchain development, and user-facing interface delivery. I've built a multi-backend Solana RPC service supporting millions of daily requests, reducing p95 latency by about 60% and outage windows by about 95%. I've experience designing governance-focused Solana smart contracts and ZK-proof-based on-chain and off-chain systems, while delivering reliable end-user products. Recently, I've shipped one of its kind GDPR compliant privacy swap and transfer pool on Solana from scratch.
I bring strong expertise in Rust, C++, MERN & T3 stack, cloud infrastructure, and low-latency system design to build robust and scalable products and improve performance of existing systems and user outcomes.

Solana Blockchain Engineer
GoQuant 2025 - 2026
I currently work as a Software Engineer at GoQuant, as a member of their 0->1 founding team, I have led their backend architecture, designed and built all their governance-critical Solana contracts and led their internal security audit cycles. Here, I have built an RPC service that handles millions of requests a day, cut p95 latency by ~60%, and reduced outage windows by ~95%. Here, I've worked across the stacks from building scalable, robust backend systems to production-grade user-interfaces to leading reliable RPC infrastructure.
