Leonidas Peligrineli

"I had the opportunity to work with Leonidas at Auren, and I can confidently say he is a standout Front-end developer. He combines advanced technical knowledge with an excellent ability to explain, guide, and unblock the team in a didactic way, always maintaining a collaborative attitude. Moreover, he is very proactive: he doesn't just execute tasks but also suggests improvements, anticipates risks, and contributes with solutions that enhance both product and engineering. The level of quality, organization, and consistency in his deliveries was impeccable. I recommend him without hesitation."

"I had the privilege of working with Leonidas Peligrineli during the last semester on a project for Auren Energia, and I can confidently say he is a highly skilled professional who conveys his seniority and experience in discussions even about everyday topics. He is a professional who encapsulates and demonstrates interdisciplinary mastery in the areas I believe are most important for a developer. He has an incredible technical mastery, from understanding application layers from data to presenter in the Front (including discussions about the application's own UI), combined with an ability to understand and solve features as problems, high scalability and tooling vision, and finally, the ability to put complex ideas and theories into simple words to guide planning and refinements. Beyond all this, he is still capable of continuing to adapt and understands very well the role of a Senior in delivering while helping junior developers in the team. Working with him as a Junior Developer allowed me to grasp more complex concepts from paper and learn new things, not just by replication but by understanding why each decision was made in the code, which usually leads to long searches and looking at other use cases. He was always willing to answer my questions, give good feedbacks, and reject my PRs 🤣 . Thanks to him, I was able to learn modern techniques and apply them with guidance on a real project, so much so that I absorbed them for myself and could explain and replicate them in other projects like modern MVVM architecture that will be part of my personal portfolio. The fact is that wherever he goes, he is a professional capable of exponentially adding value technically while generating engagement and individual improvement in every team member while delivering high-quality products. If needed, I'm available to talk more about our team collaboration experience."

"Working with Leonidas was a guarantee of high-level technical delivery. He took on one of the most critical challenges in the project: developing dozens of complex charts in React, with dynamic rules, multiple data sources, and high business impact... and he handled everything with mastery. He delivered highly performant, well-structured, and fully reusable components, raising both the visual and technical standard of the product. Leonidas has deep knowledge of frontend architecture, makes mature technical decisions, and quickly unblocks complex issues. He communicates clearly, collaborates effectively, and also mentors less experienced developers. I strongly recommend Leônidas to any team looking for a Senior Frontend Engineer capable of leading complex challenges and delivering with excellence."
