My Profile

    • Hi, I’m David. I am a Backend Engineer, problem solver, and tech enthusiast focused on building efficient, scalable systems. I currently work at PT. Cakra Radha Mustika (a subsidiary of Kalbe Group), where I design and deploy robust backend architectures, microservices, and database systems.

      What I Do

      • Backend & Cloud Architecture: I specialize in Go and PostgreSQL, utilizing Docker, Linux, and Google Cloud Platform to build reliable APIs and backend infrastructure.

      • AI Integration & Automation: I actively leverage AI models (like Gemini 2.0/2.5) to solve complex data challenges, including building automated OCR receipt parsing systems and custom retail product mapping logic.

      • Product Development: I am the developer behind side projects like Gunndalla and Warbis, utilizing the Meta Graph API and SendPulse to create automated chatbot and digital notification platforms.

      Beyond the Screen Tech is my profession, but I'm just as passionate about my offline projects:

      • Automotive Customization: I spend my weekends maintaining and modifying my campervan interior conversions.

      • Photography & Vlogging: I love testing and optimizing mobile camera setups, gimbals, and action cameras to document life and travel.

      • Travel & Exploring: Whether I'm mapping out child-friendly itineraries across Japan's autumn foliage for my wife and son or reviewing local spots as a Level 6 Google Local Guide, I love exploring new places and sharing those experiences.
