À propos de moi
Senior Full-Stack Engineer with 12+ years building production web apps in Laravel, PHP, Vue.js, Node.js, React and Next.js. I've shipped high-load B2B/B2C products in fintech, Web3 and SaaS: crypto payment and WalletConnect integrations, monoliths split into microservices on Docker/Kubernetes, an admin panel taken from 60s to 1s. You get a clear scope and a fixed price before we start, clean documented code, honest deadlines and fast replies. If your idea needs a different approach, I'll tell you instead of taking the order and disappointing you. Message me with what you're building.... Plus d’infos
