Signal Intercepts

“I had the privilege of working with Julius on AWS technologies for SMRT. In my interactions with Julius, he has demonstrated his strong technical skills, business acumen and leadership. Julius is also a keen innovator whom is always on the lookout for the latest technologies and receptive to creative ideas that can improve the user experience of the Wink+ application. One of these ideas has even resulted in his team being one of the first few adopters of Amazon Nova (Generative AI, LLM). It has been a pleasure working with Julius and I do hope that I have the chance to collaborate with him in the future.”

“Despite holding the mighty title of Head of Technology, he never acted like a ‘big boss.’ Instead, he’s the kind of leader who feels more like a supportive teammate… or your friendly neighborhood uncle (the cool and wise kind who gives great career advice over kopi). Affectionately known on the team as ‘Mr. Sunshine,’ Julius has a magical way of lifting everyone’s mood just by walking into the room. As a junior developer when I first joined, Julius played a huge part in shaping my career. He patiently shared his industry experience, taught me best practices, and always made time to guide me—without ever making it feel like a top-down lecture.”

“When I first saw Julius at work, I immediately understood what the ideal CTO should be, and where the gaps have been for every other engineering leader I’d met previously. Julius is a walking masterclass in how servant leadership, when effectively combined with deep experience, raw intellect, and a knack for mentorship in a single person, can transform entire teams and companies. What I personally appreciate most about Julius is that there is a thoughtful candor to his words. If something isn’t quite working well or making sense, I can trust him to find time to collaborate on driving a solution; conversely, if my logic is missing a critical perspective, I can trust him to be honest and help me see things in a more complete way.”

“Working with Julius in ZilLearn has been an eye-opening and life-changing experience. He is an inspiring and understanding leader who often looks out for me and advises me whenever I need it. Julius has a vast knowledge across all domains and technical expertise that feels like a walking Google (or OpenAI). I find myself always walking away with new knowledge after every session with him. He is very strategic and is definitely one of the people with the best stakeholder management skills I have ever seen. There isn’t anyone that I know without an immense respect for him.”

“Julius belongs in the top 1% of Engineering Manager / Leaders. He has the complete balance between IQ and EQ, and uses that to excel in bringing value AND purpose to the company and everyone in it. While working with Julius, he made sure that my work was challenging, there was a purpose and future in my career and most especially cared that I was being acknowledged for my work. He does not use empty and pointless words as he spends a lot of time reading books and research papers to validate his point. There’s always something to learn from him. Out of all the people I’d like to work with again Julius is definitely number 1 on the list.”
