Product-focused engineering means choosing architecture appropriate to the problem, not the trend. I prioritize maintainability, reliability, and clear domain modeling — whether that is local-first persistence on Android, transactional backup and restore, or pragmatic AI integration behind an API.
Recommendations
Perspectives from an engineering peer, a founder, and a client who have worked directly with me.
I’ve worked with Herry across Lakuyo and Alocare. On Lakuyo he owns our Android and desktop surfaces (Kotlin Multiplatform / Compose); on Alocare he contributes end-to-end across mobile, backend, web, and applied AI. He thinks like a product engineer, clear architecture, pragmatic trade-offs, and a strong bias toward shipping reliable systems. He’s dependable with ownership, easy to collaborate with across the stack, and consistently raises the quality of what we build. I’d recommend him without hesitation for any team that needs a full-stack engineer who can drive work from design through release.
Herry has been an important part of building AloCare, contributing not only as a software developer but also as a product engineer. He has taken ownership across the Android application, product experience, and UI/UX, while also supporting our AI backend development.
What I appreciate most is his ability to look beyond the code and think about the product as a whole—how it should work, how users will experience it, and how the technology should support the business. He is proactive, dependable, and able to turn ideas into practical, working solutions.
I’m very satisfied with his contribution to AloCare and value the breadth of skills and ownership he brings to the product.
Herry has helped D2S develop our mobile application while also continuously improving our existing website, including race results, administrative tools, and other features that support our running events and operations.
What makes Herry unique is that he understands our world beyond software development. As an avid runner who is actively involved in running events, he understands the needs of runners, organizers, and the community firsthand. He also brings experience in content creation, videography, and video editing, which gives him a broader perspective when thinking about our digital products.
I’m very satisfied with his work and appreciate having someone who can combine technical skills, creativity, and a genuine understanding of the running industry.
For hiring managers, collaborators, and teams needing practical full-stack and applied AI engineering with real product ownership.
