At Tronic Asia Group, I contributed to architectural decisions across the system and developed an XMPP-based SDK for messaging and real-time communication. I also integrated Asterisk-based audio and video calling with session management.
I implemented client-side end-to-end encryption for video conferencing, including a custom cryptographic key exchange protocol. I also built real-time speech transcription and live subtitles, and integrated noise suppression and virtual backgrounds.
I developed a reusable UI kit and internal libraries, introduced Module Federation, and established a monorepo development environment. I also built and maintained CI/CD pipelines and optimized performance through rendering improvements, code splitting, list virtualization, and caching.
