🙌 7+ Years of experience in full-stack web development 🏆 Top Rated Plus on Upwork | 100% Job Success Score | 7+ Years building for founders Hi, I'm Gabriel. For the past 7 years I've helped founders and teams turn ideas into real, working software, from MVPs that get to market fast to full SaaS platforms built to scale. These days, my focus is on full-stack development, AI integration, and SaaS. A lot of founders find me after a previous developer already burned through their time and budget and left them with nothing, almost always because of poor communication and the wrong expectations. With me, it's no micromanagement and complete transparency. You'll always know where things stand, what's done, what's next, and what's blocking. That's how I've helped dozens of founders launch their ideas and grow them. You can check out my case studies below to see for yourself, or read what some of my clients have said: Ben Furtado | Founder of Moonlitemoney - ⭐⭐⭐⭐⭐ "Gabriel is awesome. I was struggling to find the right developer to knock out my software MVP. I tried a lot of people who were over complicating the project and taking forever. Gabe came in and rebuilt the whole ring from scratch and did it 10x better in 1/10th the time. He understands the vision and knows how to bring it to life. I really can’t recommend him highly enough. Thank you Gabe!" Seth Carstens | Web Development Lead Nextiva - ⭐⭐⭐⭐⭐ "Gabriel was a valuable member of our web development team. He always delivered high-quality work and was willing to go above and beyond with extra hours on the nights and weekends to get the project across the finish line." Cristian Sava | CEO at Compire LLC - ⭐⭐⭐⭐⭐ "Gabriel is an exceptional engineer, truly one of the best I've worked with. His expertise and willingness to go above and beyond ensure top-notch delivery on every project. Beyond his technical skills, Gabriel stands out for his excellent communication, a rare find on Upwork. He's also highly reliable; I can trust him to complete any assigned task on time and with outstanding quality." I love working with ambitious founders and teams who want their website to stand out and perform. If that sounds like you, let’s connect.

Pula, Croatia
I’m a web developer with solid experience working on real production projects. I build, support, and improve web applications that are actually used by people, not just demo solutions. Most of my work is focused on maintaining and evolving existing systems as well as developing new functionality when needed. I regularly work with JavaScript, TypeScript (React & NestJS), Node.js, PHP, SQL, and modern CSS frameworks like Tailwind CSS. I care a lot about clean structure, predictable behavior, and code that can be understood and maintained over time. I often work with content heavy and business oriented platforms where stability and consistency matter more than trends. When WordPress is part of the stack, I’m comfortable working not only with themes and plugins but also with its core logic when deeper changes are required. At the same time, I have no problem working outside of CMS solutions on more custom setups. I’m used to joining ongoing projects, reading existing code, and contributing without breaking established workflows. I pay attention to details that affect performance, usability, and technical quality, especially on live systems that require long term support. Clear communication is important to me. Before starting work, I make sure the task and priorities are well understood, and during the process I keep things transparent and organized so there are no surprises on either side. Alongside client work, I’ve built and continue to maintain my own web platform from scratch, which gave me strong experience in ownership, long-term support, and working with live products. I’m open to long term collaboration as well as focused tasks and improvements. If you’re looking for a developer who works with modern tools, understands existing systems, and delivers reliable results, I’d be glad to talk.
