Experience
Blockchain Developer
Blocsys 2025 - 2026
Architected and deployed a prediction market platform on BSC — built a real-time order book engine processing 100,000+ trades and $5M+ in trading volume with sub-second trade matching via WebSockets + Redis pub/sub. ● Wrote and deployed Solidity smart contracts for prediction market settlement, token vaults, and RWA tokenization on EVM chains, handling 1,000+ on-chain tokenization transactions with secure escrow logic. ● Built a DeFi vault system on Solana using Rust/Anchor — integrated Jupiter DEX aggregation for automated portfolio rebalancing, processing 5,000+ on-chain transactions at 99.5% success rate. ● Designed fiat-to-crypto payment infrastructure integrating MoonPay ($500K+ processed) and Thirdweb Wallet (2,000+ wallet connections), enabling seamless onboarding for non-crypto-native users. ● Engineered backend microservices (Node.js/NestJS) supporting 3,000+ concurrent users — implemented Redis caching and query optimization, reducing API latency by 45% and blockchain data read latency by 70%. ● Architected 50+ production-grade APIs with RBAC, JWT authentication, and rate limiting, processing 50,000+ daily transactions with fault tolerance and 99.9% uptime on AWS (EC2, Nginx, PM2). ● Implemented real-time portfolio tracking and blockchain event monitoring dashboards using Socket.io, Redis caching, and Web3 event listeners for on-chain data feeds. ● Designed and developed an AI Agent API and Policy Engine for DeFi vault management — enabling autonomous AI driven rebalancing, DTF creation, and fee claims within immutable, tamper-proof policy guardrails on Solana.
