What I'm looking for

I'm looking to keep building secure blockchain products and scalable backend systems, with opportunities to solve complex Web3 problems, strengthen security, learn continuously, and lead or mentor engineering teams.

I'm building the on-chain and backend systems for Friend Space (Alfa Club), a Base social-token platform where creators tokenize shares and users trade, stake, chat, bridge funds, and access DeFi integrations.

I designed its ERC-1155 bonding-curve tokens, staking, cross-chain fund management, and upgradeable contract architecture, supported by Foundry tests, Slither analysis, CI, and a third-party AstraSec audit. On the backend, I built Hono and Node.js services for real-time chat and trading, indexing, bridging, gas sponsorship, and Hyperliquid and Polymarket integrations.

Previously at BlockPixels, I owned system design, smart contracts, and backend work for NFT, marketplace, crypto social, and analytics products. I deployed ERC-20 tokens across seven EVM chains with CREATE3, built an indexer handling 7 TB of blockchain data, and shipped cross-chain bridges, NFT minting, and marketplace functionality.

Across Sotatek, Headway, Agiletech, freelance work, and personal projects, I've led teams, mentored Web3 developers, and built products spanning DEXs, wallets, IDO platforms, CRM systems, automation tools, and launchpads. I'm always learning, with a focus on blockchain development and security.
