Lucas Freitas

Senior Software Engineer building scalable systems and solving complex problems for startups and established companies.

About

I'm a Senior Full-Stack Engineer passionate about building scalable systems, clean architectures, and intuitive user experiences. Over the years, I've worked on projects that connect technology and business, from B2B marketplaces to educational platforms and enterprise integrations, always aiming to deliver solutions that are both technically solid and strategically impactful. I currently focus on high-performance backends using Go, Node.js/NestJS, and TypeScript, alongside modern front-end frameworks like React and Next.js. I also explore AI-driven development and automation to streamline workflows, reduce friction, and elevate engineering productivity. Beyond code, I value clarity, ownership, and adaptability, the traits that allow me to move fast, learn faster, and consistently drive real results.

Recommendations

Lucas Garcia

PSM I • PSPO I | Project Manager | Product Management | MBA USP (in progress) | Digital Strategy • Tech • Content Leadership

"I had the pleasure of working directly with Lucas Freitas at Grupo CCR/Motiva, where he was responsible for implementing digital content for websites on the AEM platform. He is the kind of rare professional who quickly understands requirements without the need for extensive explanations. His logical thinking is outstanding, and he often surprises with creative and innovative solutions. In addition, he automated several processes in an extremely efficient way, significantly increasing our team’s productivity. I must also highlight that he was the fastest content implementer I worked with within the group, which I consider a true differentiator. His collaborative and positive personality made the work environment much more pleasant and productive. Without a doubt, I strongly recommend Lucas Freitas for any project or challenge that requires dynamism, creativity, and operational efficiency."
