Experience

Designed and built the React Native wrapper around Flutter/Dart plugins using a Flutter-as-a-Module approach, exposing a clean JS bridge via Kotlin and Obj-C translation layers.

Implemented the JNI/Swift bridge for secure enclave access and BLE key-transfer operations, achieving sub-3ms round-trip latency for cryptographic handshakes.

Made targeted changes at the hardware/firmware level in C (Segger Embedded Studio) — tuning connection interval, MTU, and Data Length Extension parameters. A focused MTU configuration change on the mobile SDK side improved firmware-over-the-air transfer throughput from ~1.5–2 KB/s to ~7.5 KB/s.

Engineered the complete GitLab CI → JFrog Artifactory release pipeline: semantic versioning, changelog automation, multi-platform artifact publishing, and OEM partner integration.

Led code reviews enforcing Clean Architecture and SOLID principles across the SDK. Authored integration test suites for BLE connectivity and key lifecycle flows.

Collaborated with teammates in Figma to improve the Keystone app's user experience — working through typography, color systems, shapes, and component consistency using Material Design guidelines, then implementing the designs pixel-accurately in Flutter.

Built responsive web dashboards in React and mobile screens in Flutter, applying Material Design principles for typography, color, and layout to ensure a consistent, accessible experience across platforms.

Worked from Figma mockups to implement UI components faithfully, maintaining visual consistency between design and production code.

Integrated RESTful APIs and real-time data feeds for live match statistics and recruitment analytics.

Conducted weekly office hours and lab sessions covering data structures, algorithms, and OOP fundamentals.

Graded programming assignments and provided detailed feedback to reinforce core engineering concepts.

Worked daily alongside an in-house graphic designer in Figma — contributing to app wireframes, Material Design–based color palettes and typography scales, component systems, icon sets, and shape language, then owning the engineering implementation.

Social recipe-sharing and events apps built with Flutter + Python Flask. Implemented HLS adaptive video streaming via FFMPEG transcoding workers; Hing peaked at 10K+ MAU.

IoT controller app using Bluetooth Classic (RFCOMM) for real-time LED display board programming. Custom frame-transfer protocol and animation sequencer.

Native Android (Kotlin) apps for news aggregation and retail inventory management with barcode scanning and offline-first SQLite storage.

Barcode-based employee attendance system with a FastAPI backend, offline sync, and admin reporting dashboard.
