Backend & Web3 Developer
I build and operate the backends behind NFT games, DeFi, lotteries, and emerging-market fintech — across Algorand and EVM.
4+ years shipping and operating production systems for international clients — smart contracts, real-time and REST APIs, custodial ledgers, queue workers, on-chain settlement, and the on-call that comes with it. Most of it is private client work, so these case studies walk through the architecture, the hard calls, and the numbers.

What I build
I build and operate the backends that move real value on-chain — with a specialty in blockchain integration for games: wiring NFT ownership, token rewards, provably-fair draws, and on-chain settlement into live games so players can earn, trade, and own without the game client ever touching a wallet. Around that sits the rest of the stack — smart contracts on Algorand and EVM, real-time APIs, custodial double-entry ledgers, multi-DEX DeFi, NFT minting, anti-cheat, and the queue workers and cron that keep settlement correct under load. Most of it is private client work, so these case studies walk through the architecture and the hard calls.
