Full Stack Web3 Dev | Specializing In Smart Contracts & D Apps On Solana & Evm

Senior Web3 engineer with 10+ years of software engineering experience, including 8+ years building smart contracts, dApps, and high-performance backend systems across EVM chains and Solana. Deep expertise in Solidity, Rust, and Golang, with a track record spanning DeFi lending, AMM/DEX design, NFT marketplaces, prediction markets (InfoFi), and AI agent-driven trading systems. Designed and shipped production protocols securing $13M+ in TVL and $14M+ in treasury assets, built trading infrastructure that boosted throughput by 1,800 TPS while cutting transaction latency by 22%, and led security programs that reduced vulnerabilities by 58% through audits, fuzz testing, and formal verification. Comfortable owning systems end to end — from tokenomics and contract architecture through backend execution engines, data pipelines, and frontend wallet integrations — while mentoring engineers and collaborating closely with product, quant, and security teams in fast-moving remote environments.

Experience

Senior Web3 Engineer
&Milo
2023 - 2026
• Delivered the full smart contract suite for an AI agent trading and prediction market platform — market creation, outcome resolution, escrow, and settlement — in Solidity (EVM) and Rust/Anchor (Solana), running in production with zero critical incidents since launch. • Improved trade execution speed by 35% by building AI trading agents that combine LLM-driven signal generation (GPT- 4/Claude) with on-chain execution through the Jupiter aggregator and Uniswap V3, enabling fully autonomous strategy deployment. • Boosted system throughput by 1,800 TPS and cut transaction latency by 22% by engineering a high-frequency execution engine in Rust and Go, using Jito bundles for MEV protection and priority-fee optimization during network congestion. • Eliminated manual market resolution by designing sports betting and event markets settled automatically from Chainlink and Pyth oracle feeds, backed by optimistic resolution with dispute windows. • Classified 100K+ wallets at 98% accuracy by engineering a behavioral wallet-labeling system that powers real-time copytrading of top-performing traders. • Cut data delivery latency to ~30ms while processing 2TB+ of on-chain and market data daily by architecting a real-time pipeline on Google Cloud Pub/Sub that feeds AI models, risk engines, and live dashboards. • Removed manual intervention from token launches by deploying proxy-upgradeable bonding curve contracts that migrate liquidity to Uniswap and Raydium automatically on threshold triggers. • Protected $14M+ in treasury assets and $8M+ in keeper bot transaction value by implementing Squads/Safe multi-signature governance with KMS-backed key management. • Reduced vulnerabilities by 58% and passed three external audits with zero critical findings by leading the security program — Slither static analysis, Echidna fuzz testing, and formal verification with external auditors. • Lowered operational and gas costs by 25% through calldata packing, storage layout optimization, transaction batching, and efficient backend resource management.
Smart Contract Engineer
Prime Numbers Labs
2021 - 2023
• Managed $5M+ in TVL safely through volatile markets by developing and securing core lending/borrowing contracts in Solidity with Chainlink price oracles, OpenZeppelin libraries, and tuned liquidation and interest-rate models. • Cut gas costs by 15% by designing a custom rebasing ERC-20 token using EIP-1559 mechanics and storage packing while preserving full DeFi composability. • Secured $8M+ in TVL on Polygon by engineering staking, vesting, and bonding contracts, and improved gas efficiency by 98% with a Uniswap V2 fork customized for protocol token swaps. • Increased community proposal participation by architecting a Snapshot-integrated governance module that enables onchain treasury execution. • Enabled analytics dashboards and third-party integrations by indexing protocol data with The Graph subgraphs and GraphQL APIs. • Kept liquidations reliable through high-volatility market periods by building 24/7 keeper bots in Rust and TypeScript that monitor loan health factors. • Designed protocol tokenomics and emission schedules — vesting cliffs, buyback-and-burn mechanics, and fair-launch distribution — for the token generation event. • Reduced reported issues by 20% release-over-release by driving external security audits, formal verification, and invariant testing in Foundry. • Raised the team's code quality score by 25% by mentoring junior developers through code reviews, pairing, and technical training.
Blockchain Engineer
Novus Team
2018 - 2020
• Reduced API latency by 15% by architecting a high-performance Go backend with optimized data serialization and caching strategies. • Gave creators automatic royalties on secondary sales by implementing ERC-721/ERC-1155 minting, burning, and EIP-2981 royalty contracts with off-chain metadata on IPFS/Arweave. • Boosted user engagement by 25% by designing and shipping a scalable auction engine and category system across the marketplace. • Increased deployment frequency by 40% by building a Dockerized backend with Jenkins CI/CD pipelines across staging and production. • Cut failed-checkout rates and support tickets by integrating MetaMask and WalletConnect wallet flows into the React frontend. • Delivered live bids, offers, and auction updates by developing GraphQL and REST APIs with WebSocket push for web andmobile clients. • Reduced server costs by 20% by optimizing PostgreSQL queries and database schemas in the Go backend for efficient resource utilization.
