Building High-Impact Digital Products
Full-stack & mobile developer shipping reliable web and app experiences.
About Me

Hi, I'm Zaldi Trenggono—an end-to-end web & mobile engineer who loves shipping polished products that actually get used. I build with Next.js, React Native, Node.js, and TypeScript to deliver fast, secure experiences that scale with user demand.
Recent highlights include launching an automated WiFi ticketing platform for Kanaya, boosting onboarding speed by 40%, and helping multiple early-stage teams validate ideas in weeks, not months. I focus on crisp UI, resilient architecture, and measurable results for every release.
