Asterisk, FreeSwitch, OpenSIPS, WebRTC Specialist | VoIP Systems That Scale | Backend & Infra Pro
With over 20 years of experience in VoIP, backend systems, and real-time communications, I specialize in designing, developing, and managing scalable and secure solutions using Asterisk, FreeSWITCH, OpenSIPS, WebRTC, and custom backend architectures.
I’ve worked with startups and enterprise teams across the globe—leading cross-functional developers (iOS, Android, web, backend), acting as a Technical Product Owner, and launching innovative platforms in telecom, healthcare, and unified communications.
I deliver complete solutions, from SIP infrastructure and call routing to cloud APIs and user-facing features. I'm highly proficient in Linux systems, database design (MySQL, Redis), scripting (Bash, Perl), and modern DevOps workflows (Docker, Git, CI/CD).
If you're looking for a hands-on VoIP engineer, a backend systems architect, or a technical consultant who can lead and deliver complex systems, let’s work together. I take pride in clear communication, performance optimization, and results that scale.
