I hold Upwork’s Expert-Vetted badge, placing me among the top 1% of blockchain engineers on the platform, recognized for deep technical expertise, reliability, and consistent delivery. I am a senior Blockchain Engineer with 6+ years of hands-on experience designing and delivering production-grade smart contracts, DeFi protocols, token launch infrastructure, and staking systems across Ethereum, BSC, Solana, TRON, and EVM-compatible chains. I specialize in: - Token launch & fundraising contracts (presale logic, vesting, allocations) - Staking & rewards systems (APR logic, emissions, compounding) - DeFi protocols (lending, liquidity, yield mechanisms) - Secure, gas-optimized Solidity smart contracts - Smart contract integrations with existing platforms and backends I’ve contributed to 300+ blockchain projects, including live exchanges and large-scale on-chain systems, giving me a full lifecycle understanding — from protocol design and architecture to deployment, testing, and post-launch support. Security, scalability, and long-term maintainability are always first-class concerns in my work. While I have experience with NFTs, my current focus is on real utility blockchain systems — DeFi, staking, token economics, and secure on-chain infrastructure that supports sustainable products. ⭐ 99%+ of my client reviews are 5-star, reflecting clear communication, on-time delivery, and dependable execution. If you’re looking for a senior blockchain engineer who can take ownership of complex smart contract systems and deliver with confidence, I’d be happy to discuss your project and help you move forward efficiently.
