Hendri Antonius

I’m a Frontend Engineer with 3+ years of experience building scalable SaaS platforms and real-time web applications. I focus on frontend architecture, performance optimization, and turning complex operational workflows into maintainable user-facing experiences.

At McEasy, I quickly adapted to a production Vue 2 codebase and helped deliver features across multiple teams and operational systems. I contributed to migrating Live View from legacy Vue 2 to Vue 3, improving maintainability and performance while keeping real-time fleet monitoring stable. I also reduced Google Maps API cost by 20% through a migration to a newer optimized implementation.

I’ve shipped production-ready, real-time experiences using WebSocket-based monitoring for CDM with live camera, door, and sensor visibility for incident handling. I build features with clear state management and efficient data updates—like Quick Assignment with autosave that optimized PATCH requests to persist only changed fields. I also analyze cross-feature dependencies before implementation to reduce regression risk, and I handle debugging, log analysis, and cross-team issue resolution across the full SDLC.

Beyond frontend engineering, I bring strong product and mentoring energy from my work as a coding mentor and my iOS development experience using SwiftUI/UIKit, plus full-stack work with PHP (Laravel). I enjoy communicating technical ideas clearly, learning fast in unfamiliar codebases, and delivering reliable results in fast-moving environments.
