Testimonials
Richard is a brilliant and gifted software developer who joined my team as a backend developer intern. During his internship, he has not only shown his great technical skills, but also has brought a lot of positive energies to the team. He is a fast learner, a challenge seeker, very proactive, self-motivated, and goal-oriented. Richard was able to contribute to a new feature after three weeks of joining the team, this is very impressive. When he approached the implementation of the new feature, he also thoroughly investigated the related code areas and fixed bugs as discovered. When investigation tasks are assigned to him, Richard can come up with PoCs and great presentations in a timely manner, and share the knowledge with the rest of the team. Overall, Richard is a great developer to work with and I wish him all the best in his future!
