Senior full-stack blockchain developer & lead. Production smart contracts on mainnet for Lukso, Lumia, Flare, Humanity & Wirex Pay. I build the whole stack — Solidity contracts, Go/Node backends, dApps, bots and integrations. Blockchain Lead at Gateway.fm, where I run a team of 5 shipping production systems for DeFi, oracle, L2, identity and payments clients — where transaction correctness, reliability and security are non-negotiable. I take technical ownership end to end: architecture → smart contracts → backend services → frontend → deploy, verify and support. What I can build for you: • Smart contracts — DeFi protocols, RWA / security-token & tokenization systems, NFT + staking, ERC-20/721/1155, governance, vesting; written with 100% test coverage. • Smart-contract review & audit — manual review + Slither/Foundry, threat models, gas optimization. • Backend & automation — Go and Node/TypeScript services, REST/gRPC/WebSocket APIs, indexers, oracles, event-driven pipelines, exchange & third-party API integrations, trading/Telegram bots. • Full dApps — Next.js / React front ends with wallet integration (ethers/viem), wired to your contracts and backend. What makes me different: most "blockchain developers" are Solidity-only. I ship the contracts AND the production backend AND the dApp on top. I've architected three production oracles (Haust, Lukso, Flare), the universal multi-chain indexer at Gateway, and led blockchain + backend for Wirex Pay on Polygon zkEVM. An MBA + finance background means I can also talk to non-technical founders about DeFi, payments and RWA in their own language. How I work: short consultation to pin down scope → written technical spec → build with tests → deploy and verify → support. I take small, well-scoped fixed-price jobs (a contract deployment, an audit, a bot, an API integration, a dApp fix) as well as larger architecture engagements and retainers. Proof of work you can inspect today: Lighthouse Oracle — a full pull-based multi-asset price oracle I built end to end (Chainlink-compatible Solidity contracts + 4 Go microservices + a Next.js dashboard), deployed and verified on testnet. Source + live demo are in my portfolio below.
