VOIP ENGINEER
Kyiv Call Center (Hybrid)
2021 - 2023

Joined an early-stage VoIP startup as a junior engineer and, over
2.5 years, grew into a leadership role where I defined tasks,
managed priorities, and coordinated technical decisions.
Worked with Asterisk (CLI), SIP protocols, and Linux-based VoIP
infrastructure to ensure 24/7 system uptime for call centers and
private clients
Built custom call flow logic, managed server health and logs,
handled scaling issues, and contributed to new feature rollouts.
Led automation initiatives to reduce manual operations,
implemented tools for uptime monitoring and issue alerts.
Frequently dealt with stressful production incidents (power
outages, SIP attacks, service interruptions) and developed a strong
sense of calm under pressure and fast decision-making.
Experience included network debugging, log analysis, firewall
and NAT configuration, and Twilio integration for fallback
communication.
This experience gave me a deep understanding of telecom
reliability, problem ownership, and how to lead through real-world
operational chaos.
