"The successful build, customer success and subsequent acquisition of Kormoon would not have been possible without the diligence, care and skill of Henry. His world class skills would be a vital asset to the technology scene."
"Henry is a dedicated, skilled, and innovative professional. He led the modernization of our frontend - upgrading from Vue2 to Vue3, migrating to Pinia, and raising test coverage to 56%. I wholeheartedly recommend him."
"Henry took on a team leadership role quickly after starting, becoming a trusted member of the team. He was always communicative and proactive. I would jump at the chance to bring him onto any software team."
"Henry contributed to several mobile and web applications for global clients. He initiated and grew our community of engineers in Rwanda and led technology engagements with speakers from all over the globe."
"I worked with Henry in a mentor-mentee capacity where we collaborated on different projects. He excelled at both tasks by delivering high quality, working code in a timely manner and under specific time constraints. He was also a very effective communicator. I would strongly and without hesitation recommend Henry to any company considering him."
"I personally mentored Henry to coding. He came onboard with absolutely no knowledge of computer science, but since then has acquired a lot of valuable skills. I have been mentoring students on web development since 2013, but Henry is one of the most outstanding students I have seen over time because he came from an entirely different background of Banking/Accounting, and persisted to shifting it through."
