Kaung Khant Hein

I’m a self-driven software engineer with 1+ year of professional frontend experience and a rapidly expanding full-stack skill set. I specialize in React.js, React Native, and TypeScript, while growing hands-on expertise in Go (Golang) backend APIs and PostgreSQL schema design.

At DevelopX, I built core frontend architecture with React 18 and Vite, delivering optimized builds and fast rendering. I integrated Google Maps API and Leaflet.js for interactive, map-based discovery, implemented multi-language support (EN, JA, KO, ZH) with i18next, and developed smooth tab navigation using Framer Motion animations. I also built a favorites management system and worked with the backend team on API contracts, error handling, and performance optimization.

In my independent projects, I shipped production-grade experiences end to end using an AI-powered SDLC workflow. For Techzy, I designed a complete PostgreSQL schema via ERD modeling, built and tested a Medusa.js backend locally with Docker, coordinated AI agent sessions with MCP, and powered push notifications through Firebase Cloud Messaging using Firebase Admin SDK and Notifee. For NextBite, I implemented a Go REST API backend with multi-tenant architecture and paired it with a React Native Expo frontend featuring brand-specific theming and ordering flows.

I’m passionate about contributing to high-impact teams, learning fast, and building products that solve real problems. I enjoy turning business requirements into structured artifacts—like ERDs and UI components—and then shipping measurable improvements through thoughtful architecture and reliable testing.
