    Flavio, you are an extremely creative, fast, adaptable and aggregating professional, an incredible architect. He has an impressive ability to look beyond and predict trends, based on his vast experience and observation of the whole. The way you create solutions is disruptive, and as outcomes you deliver extremely simple and relevant scenarios based on complex problems. You have fun working and the more complex the problem, the greater your engagement and level of delivery. In addition to being self-taught, he is very good at teaching and mobilizing people. Another differentiator is its solid knowledge in secure development. Thank you for your continued partnership, it is a great privilege to learn from you every day! :)

  • José Canal, SRE, Liber Capital

    I've been working under Flávio's management for about a year and it has been an amazing experience. His ability to deal with problems and come up with new ways to achieve results is a continuous inspiration. He is always open to discuss new ideas with the team and knows how to bring the best out of each person. Flávio is a kind person and looks at the human side of the team, which, in conjunction with his broad knowledge, makes him an outstanding mentor. As a team member or a leader, Flávio earns my highest recommendation. I'm very grateful for having crossed professional paths with him.

    I started my career with Flávio as one of the company's leadership figures. Flávio is a professional who is fully involved in all the projects he participates in, seeking to understand the role of the people involved and jointly develop the best solution to problems (both in technological and human terms - he understands and makes clear his concern with physical and mental health of professionals involved in the projects). Flávio provides leadership with technical excellence, and always tries to make the work environment efficient, but also pleasant.

  • Marcelo Lipienski, Backend Developer, Liber Capital

    I had the pleasure of meeting Flávio in our adolescence, when we both began our learning in systems development. At that time he already demonstrated immense dedication and curiosity. Over the years I followed his career and always sought to be inspired by his various professional achievements. About a year ago I had the pleasure of working directly with him under his leadership, and I can confidently say that Flávio is a leader who is very loved and respected by his team. He is always looking for new knowledge and faces all the challenges in front of him head on. Flávio is an intelligent, extremely competent and persistent professional :)

  • Rafael Mello Campanari, Lead Frontend Developer, Veridu Ltd

    Working with Flávio was inspiring! Backed by his knowledge of Unix, Severs, and PHP Flávio was key to build fast and reliable software delivered in time. Beyond his tech skills, Flávio is great in communicating and creating that "sense of team" that we had at the time. I would greatly recommend Flávio to a company that needs someone to rely upon in tech and management aspects.

  • Rasmus Groth, Co-founder and CEO of Veridu Ltd

    Flavio and I founded Veridu together in Copenhagen and have worked closely since. Without Flavio there would have been no Veridu. Not only is Flavio an outstanding software architect and full stack developer, but he is also one of the best collaborators I have met in my life. He has an uncanny ability to listen enthusiastically and he was able to recruit a great team and command their complete loyalty. Competent, loyal and creative - Flavio is a good friend and a great guy to have on your team.

  • Cássio Pereira, Head of Machine Learning, Veridu Ltd

    Flávio is an extremely dedicated software architect. He has 15+ years of experience under his belt designing and implementing Web-based software solutions. As a CTO that managed a diverse group of developers, one of his main philosophies was "don't just talk the talk, but walk the walk". Supporting and motivating the team while working very hard is his daily MO. If you need a very experienced software architect with excellent people-managing skills, he is your guy.

  • Vinícius Campitelli, Co-founder of AppDeck

    Flavio is an amazing entrepreneur and very dedicated to his job. Besides advanced programming skills, he has great abilities at planning and designing solutions in web applications for the customers at our company, and is someone that will not stop improving a software until he is completely satisfied with it. I am pleased to say that I have the opportunity to work with someone as talented as him.

  • Eduardo Alberice, Co-founder and Development Director of W1Host.com

    Flavio was the creator of the company and the person who knew everything to start the business. After starting the activities, Flavio got responsibility on managing our server and did it very well. Many of the good ideas came from him, one of them was the strategy that gave us a big number of clients in a few months.

  • Cícero Neto, Media and Technology Analyst, Kingo Labs

    It was a pleasure to work with Flávio Heleno in such a short period at Kingo Labs and I could see that he is a very intelligent, decisive and determined person. I learned about your passion to join Kingo and leave an excellent job during your time there. Keep it up and you'll go far.

  • Maria Carolina Cintra, Co-founder and CEO of Kingo Labs

    I had the privilege of having Flávio on my team for a short time, but he left his mark and became the best developer to have ever worked at Kingo Labs. Creative, responsible and extremely intelligent, he knows how few others can deliver clean and functional work. Unfortunately, Flavio worked in a company in crisis and did not have the opportunity to have a calm environment to work in, but he still overcame himself, showing professionalism until the end. Flavio is an excellent option for any development team, with a great advantage: he knows how to work remotely, with quality and commitment. I'm sure he will be a great entrepreneur, as there is no shortage of ideas and capacity for achievement here.
