What other says

Eduardo Stuart
Senior Software Engineer
"He is in the top tier of developers I've worked with. He is excellent in all aspects as a software developer should have with great communication skills, excellent ability to design solutions, code skills, and troubleshooting problems. It was a pleasure working with him and I sincerely hope to work with Jecan again."

Alessio Evangelista
Tech Lead
"I had the pleasure to work together with Jecan to build a new platform from scratch. From a more technical point of
view, his coding skills are awesome. Clean, robust and very mantainable code is what Jecan delivers the most. His skills
about setting up the architecture of the application was also something we all could rely on."
"From more personal and
social point of view, I was amazed on how we could work together in a very unexpected syntony from day 1 and this led to
an enjoyable and fun way to write many lines of solid and reliable code in very short amount of time. I hope to have the
chance to work with him again very soon."

Marjon Siero
Product Designer
"Jecan played a key role in the company. Without hesitation he is always willing to help and advice colleagues with their tasks and is not afraid of a good challenge. Besides delivering what he is tasked with, Jecan always goes a step further, making sure the users get the best experience."

Denis Mysenko
CTO
"Jecan worked in our backend engineering team and I can vouch that he writes clean, modern Laravel code. He is very punctual as well, always attending any meetings on time. If you are building a Laravel product, Jecan can be a great asset for your company!"

Oleksander Dyriavin
Lead Software Engineer
"Jecan isn’t just a technically exceptional software developer; he’s also a standout leader. He joined the team recently
coming into a fast-paced and, at times, the chaotic environment where deadlines were often tight. Not only were his
technical skills robust, but he also shined when it came to accuracy."
"When Jecan was working on a project, our
error-correction needs were always reduced by half or more thanks to his outstanding diligence and attention to detail.
Plus, Jecan never shied away from sharing his knowledge with others and often took the reigns when others weren’t sure
how to proceed. Calling him an asset seems like such an understatement. As he works to take the next steps in his
career, I wholeheartedly recommend him to any company looking for a reliable, accountable, and highly skilled software
developer."

Khendi Lee
Head of UX
"He is someone that would open for challenges and solve problems as a team-player."
