I’m an experienced Technical Support and VoIP specialist with over 15 years in IT systems, troubleshooting, and telecom environments. My background includes working with Asterisk, FreePBX, Vicidial, and cloud-based telephony platforms, where I’ve handled SIP issues, call routing failures, messaging delivery problems, and carrier-related errors. I’m skilled in diagnosing complex technical issues using logs, system reports, and vendor documentation, and I focus not just on fixing problems but on identifying root causes to prevent recurrence. I’ve also worked with call center environments, DID reputation issues, and messaging/call compliance-related challenges. I’m comfortable working independently, documenting technical processes clearly, and collaborating with vendors and internal teams to resolve issues efficiently.
Experience: 2 - 5 years
I have hands-on experience in Linux system administration, server optimization, and supporting VoIP and contact center platforms like Asterisk, FreePBX, and VICIdial. On a day-to-day basis, I work on performance tuning, service monitoring, log analysis, security hardening, and troubleshooting system issues to keep everything running smoothly. I’m also comfortable with SSH, shell scripting (bash), and cron automation, and I regularly handle network and application-level issues in Linux environments. My main focus is keeping systems stable and reliable, and making sure problems are properly fixed at the root, not just patched temporarily.
I have deployed and supported 100+ VICIdial and Asterisk systems worldwide, building call center infrastructures across the US, UK, Australia, and Asia. I’ve helped manage and optimize call center operations across both inbound and outbound campaigns. My strengths include campaign setup, dialing strategies, and lead management, all aimed at improving contact rates and increasing agent productivity. I’ve also been actively involved in overseeing call center teams and daily operations to ensure smooth and efficient performance. On the technical side, I handle advanced troubleshooting such as resolving SIP and RTP issues, managing carrier integrations, and fine-tuning system performance to maintain a stable, high-performing environment. I also have experience mitigating “Scam Likely”/“Spam Likely” labeling and ensuring compliance with STIR/SHAKEN standards to support call deliverability and caller ID reputation.
I’m a DevOps IT professional with experience in both Linux and Windows system administration, server optimization, and managing production environments. I focus on automation, monitoring, and troubleshooting to keep systems running efficiently, securely, and with minimal downtime. My experience spans cloud and on-premise infrastructures, CI/CD pipelines (including Docker, Ansible, and related tools), shell scripting, and day-to-day operations such as performance tuning, log analysis, and security hardening. I’m also skilled at quickly diagnosing and resolving both infrastructure and application-level issues.
I have solid experience working with MySQL in Linux-based environments, primarily in support of VoIP and call center systems like Vicidial, Asterisk and FreePBX. I handle database troubleshooting, query optimization, performance tuning, backups, and log analysis to ensure reliable system performance. I’m comfortable using SQL for data extraction, reporting, and debugging system issues, as well as maintaining database integrity in production environments. My focus is on keeping databases optimized, stable, and responsive to support critical applications.
