Full Stack Blockchain Developer

I’m a backend-first engineer with 5+ years of hands-on experience — 3+ years in Web3 and 2 years in full-stack development Rust(async services, performance, safety). I love building secure, scalable backends and dApps, and making on-chain logic feel seamless for end users. Most of my work has been around Solana (Rust/Anchor) and Ethereum (Solidity), where I delivered DeFi products, boosted backend performance, and even built tools to make smart-contract audits faster and safer.

I enjoy owning projects end-to-end — from smart contracts and protocol design to APIs, CI/CD, and production ops. I care about shipping things that are not just technically solid but also useful for the business. Hackathons and research keep me sharp, and I’m always curious to explore new tech and bring it into real-world products.

For me, the best teams are those where people take initiative, share knowledge freely, and push each other to grow. That’s the kind of environment I thrive in.

2023 - 2025

Noders | Full-Stack Blockchain Developer October 2023 – Now (1.5 years) Improved audit workflows: built a bytecode-to-source decoder for EVM (Rust + Solidity-like IR), which helped auditors spot vulnerabilities faster and reduced external review expenses. Boosted cross-chain engagement: designed a quest validation engine for Solana & Ethereum (Anchor + Solidity + Chainlink Automation), making onboarding smoother and increasing daily active users by ~15%. Delivered a DeFi questing platform: shipped a full-featured app with swaps, staking, lending, and bridging plus wallet authentication (Next.js + wagmi). The platform hit 10k+ transactions in its first month. Enhanced throughput: migrated heavy backend services from Java/Spring to async Rust, cutting response latency by ~30% under load and making system performance more predictable. Expanded dApp capabilities: integrated Uniswap v3 SDKs and multicall so users could execute complex swaps in a single click without multiple approvals.
