Senior Go Backend Engineer at InnoTech, developing SIP-WebRTC conferencing systems and Go-based media services.

At InnoTech, I contribute to DION, an enterprise video conferencing platform connecting SIP systems with WebRTC conferencing. I developed SIP signaling functionality, built a custom SDP negotiation component in Go, and implemented BFCP floor control.

I also developed major parts of DION’s GStreamer transcoding layer, with dynamic pipelines for video and audio codecs. I improved media stability by refining RTP routing and integrating jitter handling, RTCP reports, and feedback mechanisms.

At ChangeHero, I designed the microservices architecture for FinchPay and guided its development through production launch. Earlier, I developed Go services and frontend components for fintech, marketing automation, and remote gaming projects.
