SUMMARY
Junior full-stack developer (smart contract developer) with 1 year of commercial experience at Boosty Labs. I
ship dApps end-to-end: Next.js frontends, TypeScript APIs, event indexers and Solidity contracts. I love
learning by building — every project below is how I learned its stack. Looking for a team where I can own
work that goes to production.

• Built a batch settlement layer on Tron: 3 contracts with Merkle-proof checks, timelock and on-chain fees.
• Adapted a Safe-style multisig to Tron and wrote JavaScript test suites for client contracts.
Smart Contract Developer Intern — Boosty Labs Sep – Oct 2025
• Built a decentralized file storage protocol with EIP-712 signed storage attestations.
