Chi sono
I’m a full‑stack web developer helping businesses turn ideas into fast, secure, and scalable web applications. I build responsive frontends, robust backends, and clean REST APIs using modern technologies, integrate relational and NoSQL databases, and connect third‑party services like payment gateways and email providers. I focus on performance, security, and SEO‑friendly structure, follow clean code standards, and use Git for version control. You’ll get reliable communication, clear documentation, and on‑time delivery tailored to your goals.

Esperienza lavorativa
Full Stack Next JS / React JS Developer
SaaSflow • Freelance
Apr 2024 - Jan 2026 • 1 yr 9 mos
For the past few years, I’ve been working as a full stack Next JS / React JS developer, helping clients build SaaS MVPs, startup platforms, and custom business web applications. I specialize in turning ideas into production-ready products that are fast, scalable, and easy to maintain. My work typically includes planning the architecture, structuring the frontend and backend, and implementing clean, reusable components using React JS, Next JS, and Tailwind CSS. I build responsive interfaces, connect secure APIs, integrate databases, and set up authentication and protected routes so your app is ready for real users, not just demos. I’ve delivered projects such as SaaS dashboards, internal tools, multi-page business websites, and high-converting landing pages for founders and small teams. On each project, I focus on performance, SEO basics, and a clear codebase so future changes are smooth and safe. Beyond coding, I’m used to working directly with non-technical founders. I help clarify requirements, suggest better flows or structures, and communicate progress in simple language. I regularly work with tools like Supabase, REST APIs, Stripe or other payment providers, and deploy most projects to platforms like Vercel. Even though I’m an independent developer, I treat every project like a long-term product, not a one-off website. My goal is to be the “go-to” Next JS / React JS developer you can rely on as your startup grows and your app needs new features, integrations, or optimizations. Would you like a second shorter “experience” entry focused specifically on SaaS MVPs, so your profile shows more depth without inventing a traditional job?
