Joao
Bosco

Full Stack Web3 Engineer | TypeScript & Python Specialist I am a specialized developer focused on Blockchain architecture and Process Automation. I build secure, type-safe decentralized applications and efficient automated systems designed for stability and performance. My Core Expertise: 1. Advanced Web3 Development (Full TypeScript) I build robust dApps using a strict TypeScript stack to ensure bug-free code and maintainability. DeFi Projects: Developed a complete Decentralized Exchange (DEX) entirely in TypeScript, featuring Liquidity Pools, Staking, Faucets, and Lottery systems. Smart Contracts: Proficient in writing, testing, and deploying secure contracts using Solidity. 2. Strategic Backend Architecture (Python vs. TypeScript) I choose the right tool for the job: Heavy Computation (Python): I use Python for backends requiring complex calculations, data analysis, and AI integration. High Stability (TypeScript): For scalable, lightweight, and bug-resistant
