I worked directly with Oscar at Klook. Oscar managed our business automation tasks. The key quality that stands out for Oscar is the positive attitude and the willingness to take up rather complex problems and deep dive to find solutions. He learns fast and never afraid of hard tasks. He has the attitude to be the great professional.
Lionel Lau
Product Analytics Lead at Zuellig Pharma, SG
Oscar has done a great job in helping the Competitor Intelligence and Business Automation projects at Klook as a junior Data Analyst. During his work experience at Klook, he has demonstrated an extensive range of responsibilities including business communication, workflow management, data mining, expanding the company's data by incorporating external sources, improving data collection techniques, data visualisation, and doing ad-hoc analyses. He is also very responsible and detail-oriented, qualities that make him stand out.
Benjamin Kramer
Senior Business Intelligence Manager - Operations at Drizly, Boston
Oscar is a thoughtful, hard working analyst who is passionate about data, solving problems and communicating insights - as I had the opportunity to manage him, I would give him a strong recommendation as he is both technically skilled and a natural fit within a team. With challenging projects, Oscar came up with innovative solutions to problems that were previously unknown, made sure that his stakeholders understood what he had done, and was eager to learn new skills that would enable him to work more efficiently and effectively. He really has a positive attitude for helping others, and doesn't stop at just 'good enough'. Oscar was a pleasure to manage as he would constantly have new ideas to try while meeting the challenging standards placed upon him all the same. I also observed him communicating well with other teams in cross-functional projects - a skill not everyone has and can really be crucial when it comes to measuring productivity and success. I would personally recommend Oscar - he not only has the drive to continually learn and improve himself, but he has that effect on others around him as well.
