Agustinus Nathaniel

👋 Hi, how are you?

I’m Nathan, a Software Engineer with a focus on frontend development for web and mobile. My interest in technology started early, where I enjoyed exploring operating systems, applications, and user experience design. This curiosity led me to pursue a career in tech, where I now work on building user-centered products that solve real-world problems.

With years of experience, I blend technical skills and a practical approach to create solutions that are both functional and aligned with business needs. I’ve collaborated with various teams to improve processes, foster growth, and focus on delivering effective and user-friendly products.

    Your leadership has been very strong — you’ve provided clear direction, managed priorities well, and created a supportive environment that helps the team stay productive and motivated. You also encourage collaboration and give room for others to contribute their ideas, which I really value.

    I think you communicate with the team very effectively, your directions are clear, and you make sure everyone understands their priorities. You’re also approachable, which makes it easy to raise questions or concerns.

    Nathan is a very organized and intelligent engineer, always think more about optimization, and try to look from multiple point of views regarding a product. Over the course of his career in pinhome, he has standardized our workflow in Ares squad, made a lot of documentation to help other fellow engineers. He also discussed alot with the products to confirm and ensure there is no mistake when delivering a product. A good role model for any other engineers.
