Co-founded and scaled a Telegram-native bot ecosystem to 1.7 million users — built for high-volume, real-time transaction processing across multiple concurrent services. Designed and deployed on-chain smart contract reward infrastructure integrated into a raid bot, handling automated ERC-20 token distributions triggered by user participation events with strict fund safety guarantees. Deployed Solana Token-2022 transfer hook programs to mainnet implementing whitelist-based transfer restrictions, role-based access patterns, and admin bypass logic — production contracts with real fund exposure. Architected a PostgreSQL-backed game engine across 18+ tables supporting a high-concurrency distributed system — covering player state, transaction ledgers, inventory, leaderboards, and treasury management.

Joined as a community moderator and advanced to one of the top decision-making roles, outperforming a team of six across technical and operational responsibilities. Designed and deployed Solidity smart contracts for an EVM token launchpad on Ethereum and L2s — with rigorous security reviews, gas optimization, and automated test coverage prior to every deployment. Delivered ERC-20 and ERC-721 contract solutions for DeFi protocols, NFT projects, and token launches — prioritizing fund safety, reentrancy protection, and access control best practices. Provided technical consulting to crypto projects on EVM architecture, on-chain security, and smart contract design.
