Hi, I'm Jesther

Mobile App Developer · AI-Assisted Development · Flutter & Dart

I build high-quality apps with an AI-first development workflow — Claude Code, Gemini, and automation at every step.

Building apps smarter
with AI-first development

I'm a developer based in the Philippines who ships polished cross-platform apps using an AI-first workflow. Over the past four years, I've worked with clients across the globe — shipping apps that serve thousands of users on both iOS and Android.

Claude Code is my daily development environment — I use it for architecture decisions, implementation, debugging, and code review. Combined with Gemini and n8n + MCP automations, AI tools are integrated into every stage of my workflow, from planning to deployment.

Beyond mobile, I bring full-stack capabilities including Rust systems programming, Laravel/PHP backends, Firebase integrations, and workflow automation with n8n. I care deeply about clean architecture, smooth UX, and writing code that other developers actually enjoy reading.
