WHERE I DELIVER Working as a Full Stack Developer React Node, I built a multi-tenant B2B SaaS platform with React, Next.js, and Node.js — OWASP-compliant authentication, role-based access control, custom workflow logic, and full Stripe billing (Subscriptions and Connect), backed by PostgreSQL via Prisma with REST and GraphQL APIs on AWS. Building as a React Developer with the OpenAI and Anthropic APIs, I developed an AI-powered SaaS product with React, Next.js, Node.js, and Supabase — RAG pipelines, embeddings, semantic search, real-time streaming, Stripe Checkout billing, and an offline-ready PWA on Vercel.

Complex features like authentication flows, payment processing, real-time data, and third-party integrations fall under my Front End Developer work. Deep App Router, Server Components, SSR, SSG, and ISR experience comes from my time as a React Next.js Developer and Node.js Developer, plus API routes and middleware.

TECH STACK On the frontend, I build with React, Next.js, and TypeScript, styling with Tailwind CSS and Shadcn/ui and handling state with Redux or Zustand — whatever keeps the codebase easy to hand off. The backend runs on Node.js, usually via Express or NestJS, talking to PostgreSQL through Prisma, or to Supabase and Firebase when a project needs managed auth and real-time out of the box, exposed through REST or GraphQL APIs. I deploy to AWS or Vercel with GitHub Actions running CI/CD, so every push ships cleanly. When a project calls for OAuth, webhooks, transactional email via SendGrid, or automation through Zapier, that comes built into the stack, not bolted on later. MIXED-STACK SUPPORT Python, PHP, Laravel, MySQL, MongoDB, Redis, WordPress, Java, FastAPI, jQuery, and Web3 round out a broader Python Developer, Wordpress Developer, and React Web Developer skill set — and as a Mobile App Developer, I pick up inherited code and mixed stacks quickly.

👋 Hi, I'm Mario I've been building websites for 15+ years, and what sets me apart is pretty simple: I have a Master's in Marketing, so I don't just build sites that work technically – I build sites that work for your business. Code and strategy together, not one or the other. ✅ What I Do Best: I specialize in WordPress (custom themes, Gutenberg, plugins) and Webflow (Client-First, complex CMS builds), but I'm equally comfortable with Next.js, headless setups with Directus, or migrating legacy sites to modern platforms without losing SEO. I've built everything from 20,000+ page database systems with custom search functionality to multilingual e-commerce sites for international clients across Switzerland, Mexico, USA, and Australia. Performance is non-negotiable for me. I consistently hit 100/100 Core Web Vitals scores, achieve #1 Google rankings through technical SEO, and optimize sites that actually convert – like the one generating 60 leads/day and €1-2K in daily revenue. ✅ My Background: Master's in Marketing from Portugal. My dissertation was on consumer behavior and purchase decisions, which directly shapes how I think about website structure, content hierarchy, and conversion optimization. I'm not just executing designs – I'm thinking about whether this actually serves your business goals. I've worked with clients like Xtensio (LA-based SaaS) for 3 years, growing their organic traffic to 2,500+ daily clicks. I've led major migrations (2,000+ URLs from Drupal to WordPress preserving all SEO), built custom platforms, and helped businesses scale their digital presence strategically. ✅ How I Work: I don't just take orders. I ask questions. Does this content hierarchy make sense? Will this convert or just look pretty? Is there a better way to structure this? That proactive, strategic thinking is why clients stick with me for years, not just one-off projects. Clear communication, no hand-holding needed, and I work remotely with clients across time zones (US, Canada, Europe, Australia). You'll always know where things stand. ✅ Tech I Work With: WordPress (Gutenberg, Elementor, Kadence, custom development), Webflow (Client-First), Next.js, React, Directus, Shopify, Squarespace. SEO tools like Rank Math Pro, Ahrefs, Semrush. Automation with Zapier and Make. API integrations, payment gateways, CRMs, analytics. Figma for design when needed. ✅ Looking For: Long-term partnerships with clients who value strategic thinking, not just technical execution. Custom WordPress builds, Webflow projects, platform migrations, performance optimization, technical SEO – if it involves building something that drives real business results, I'm interested.
