Cloudflare optimization for WordPress site
Excellent work. Facundo fixed our WordPress site and made it noticeably faster by optimizing our Cloudflare settings. Fast, professional, and highly recommended. He is now part of our team.
About Facundo
Full-Stack Web3 & Next.js Engineer | EVM, Product-Grade Frontend
Montevideo, Uruguay - 6:55 am local time
I'm a full-stack engineer specialized in Web3 integrations and high-performance
frontend — the intersection where EVM meets great UX. I work with founders and
product teams who care about what they're building, not just who's cheapest.
What I bring to the table:
→ NFT marketplace development (ERC-721/1155, minting, migrations, royalties)
→ Wallet authentication & Web3 integrations (wagmi, ethers.js, viem, WalletConnect)
→ Next.js & TypeScript at scale — clean architecture, fast load times, real DX
→ Smartcontract Development — transparent and secure for your business
→ Backend fluency in NestJS — I can own the full stack when the project calls for it
I've shipped platforms that handle real users and real money. I understand that
smart contract logic is only half the work — the wallet UX, error states, and
gas feedback are where trust is built or lost.
I also build product outside of client work. Cadetería Punto Centro is a
logistics SaaS I designed and built from scratch: QR-based package tracking
(à la MercadoLibre), AI-optimized routing, client-level P&L dashboards, and
a full admin panel. It runs a real business in production.
I'm selective about what I take on — not because I'm difficult, but because
I only commit to work I can do exceptionally.
If you're building something that matters and need an engineer who thinks like
a product person: let's talk.
