“Jefferson is one of the best developers I have worked with over the last 10 years. He is intelligent, a hard worker, extremely dependable, and has been a huge asset to our project over the last year.

Jefferson started out as a Frontend developer on our project, but quickly proved he could also take on Backend work. He was then promoted to a Full-Stack developer. Jefferson thrives in any developer role. He makes a point to understand the requirements at hand and always asks intelligent and relevant questions. He is an excellent communicator when it comes to providing explanations or statuses of tasks. When we first started working together his English was slightly lacking, but after only a few months his English drastically improved and is now really great. He is extremely dependable and goes above and beyond to ensure his work is completed correctly and on time. He often steps up to help other team members finish their work as well.

Working on an extremely fast paced and demanding project, Jefferson has continuously excelled and risen to the occasion. He tackles problems with a smile on his face and has always been a pleasure to work with. He is a true team player in every sense of the word and any team would benefit significantly with him on it.”

— Hayley Lerner, Senior Product Owner, CSPO Sweatworks.
