I build scalable Web2 and Web3 platforms, smart contracts, and reliable decentralized applications.

At Fileverse, I engineered and launched dDocs and dSheets, a decentralized productivity suite providing secure real-time collaboration over on-chain data with cryptographically verified storage. I also deployed ERC-4337 and ERC-2771 smart contracts, meta-transactions, gasless authentication, EIP-712 signing, and blockchain UX for transaction states and ENS identities.

Previously at Netacles Digital, I architected full-stack platforms for thousands of active users across e-commerce, B2B, and NGO sectors, migrated legacy PHP systems to React, TypeScript, and Node.js, and built a 99.9% accurate payments and invoicing system. I bring ownership to reliable, future-proof systems through design systems, automated testing, CI/CD, cloud infrastructure, and production-focused performance work.
