I am pleased to recommend Jeffry Hermanto, my coworker and friend, through this testimony letter. I have known Jeffry for more than eight years. I have found Jeffry to be hard-working, diligent and of high moral and ethical standards. He has also demonstrated an ability to handle sensitive and confidential matters with mature discretion. I have worked with Jeffry in several projects; either business and social works. I can testify that he is a person who does his works with passion, fully dedicated, focused and sets a high standard in everything he does.

Having supervised Jeffry Hermanto for the last few months, I have witnessed his concerted efforts to improve the daily performance of his tasks, and I have observed his desire to meet the demands and expectations of his co-workers and environment. Given the integrity and strength of commitment demonstrated by his past performance, I would like to recommend Jeffry Hermanto as a suitable candidate for the position of Mobile Engineer at your company.

Marcelo Milhomem

I was working with Jeffry in the new Loadsmile Driver App that built using Flutter. His Flutter skill is great and he very cares about the details, especially the one that related to the UI/UX implementation. On top of that, Jeffry also encourages himself to be better every day by learning any best practices in the community. Having that said, I would recommend Jeffry without reservation for your Flutter Engineer and I believe any team would be lucky to have him on board.

Harits Fahreza Christyonotoputra

Head of Engineering Loadsmile

I have worked with Jeffry on two complex projects and in both cases, the work was done on time, on budget, and with a high degree of professionalism. Across the board, everyone enjoyed working with Jeffry. Jeffry not only did exceptional work based on the specs we gave him for each project, but he also gave input on how to make the end product even better and cared about how users would engage with the builds. I will be using Jeffry again in the future and would highly recommend his services to anyone.

I rarely come across real talents who stand out like Jeffry. I had the pleasure of working with Jeffry for 1 years at Sprout Digital Labs, collaborating on several project teams. Jeffry's ability to handle multiple projects was unlike any I’ve seen before and made a dramatic increase in the productivity level of our company. No matter how tense a meeting, Jeffry made sure everyone left with a smile. As a team member or a leader, Jeffry earns my highest recommendation.

client

Sari Harasti

Jeffry's talent and experience proved immensely valuable for our latest web project. He was involved from the very beginning, providing advice and guidance even before we signed the proposal. The work we received from him was top-notch, thoroughly documented, and full of touches that show his commitment to quality. I can’t recommend him highly enough.

client

Not many people can implement ideas as Jeffry can. He was solution-oriented and surprisingly he comes up with a Nutrix web application that I did previously on paper (Analisis Kebutuhan Nutrisi). He is also very kind and easy to deal with. What a great professional to have!
