About Me
I am a Full Stack Software Engineer with 9+ years of experience building and scaling web systems. I founded and scaled my own multi-tenant SaaS to 10,000+ paying recurring users at 99.9% uptime (owning product, PHP/Laravel + MySQL engineering, and Linux/Cloudflare infrastructure in production as a one-person tech team). Today I deliver software for B2B clients: marketplaces, operations SaaS, dashboards, CRM automation, AI agents and security audits. Mostly in TypeScript, React/Next.js and Node.js, with production work in .NET, PHP and Python.

What clients say
Real reviews from clients. Nothing edited, nothing staged.
“Fellipe is very professional and keeps communication constant: patient, collaborative, and always available to clear up questions. Commitment to the deliverables, flexibility to adjust the scope to the project's reality, and a great attitude throughout. He delivered an important part of the operational structure, stabilizing processes and implementing relevant integrations. A few features were left for a next phase, but I'll definitely rehire him to keep evolving it.”
“The problem took some work to solve, but he did exactly what needed to be done, in a much better and more stable way. I thought I wouldn't manage it, but he went ahead and exceeded what I was expecting. He may take a little while to reply, since he works on other projects (after all, the guy is good), but once he takes it on, he listens carefully to what you want to build.”
“Highly recommend. Fast and very professional. You can hire him with your eyes closed, very professional.”
“A high level of professionalism, knowledge, proactivity, and ethical conduct.”
“Highly specialized, committed to the result and to the deadlines.”
“Fellipe was very quick to grasp what needed to be done and delivered it with great quality.”

“Very attentive to detail.”
“Great work and great service.”
“Attentive to detail.”

Before you hire
The questions people ask me before we start.
It depends on scope, but most projects run in 2–6 week sprints with something usable at the end of each one. You get a realistic estimate up front, and if the deadline moves, you see it in your portal, not after the fact.
