Infrastructure

Hospital voice and network projects

Problem
Hospital projects needed new phone systems and network wiring, with PBX vendors, carriers, IT staff and field technicians all involved.
What we did
We coordinated the project end to end, managing the phone-system and cabling vendors alongside the hospital IT team and on-site technicians.
Result
One accountable point of contact across every vendor, from planning to working phones.
Infrastructure

Hosted PBX onboarding at scale

Problem
Many businesses moving to a hosted PBX platform needed onboarding, and call problems slowed them down.
What we did
We led VoIP implementation and onboarding, and diagnosed registration, trunk and call-quality issues with SIP traces and Wireshark.
Result
150+ business clients onboarded, with faster issue resolution.
Infrastructure

Multi-site hospitality Wi-Fi and monitoring

Problem
A multi-site hospitality operation needed reliable guest Wi-Fi and 24/7 network support.
What we did
We ran predictive Wi-Fi surveys and on-site walkthroughs with Ekahau, and deployed Zabbix monitoring on Ubuntu.
Result
Coverage planned from data instead of guesswork, and problems visible before guests complained.
Technology

Carrier cutovers without surprise visits

Problem
Internet and phone cutovers depended on field technicians arriving with the right information and parts.
What we did
We prepared a written port map (ISP → firewall → switch → PBX/gateway), quotes and parts lists before each technician visit, and traced SIP and RTP failures with carriers and site IT.
Result
Technicians arrived with a plan, and voice issues were traced to the right party.
Software

Automation for a support team

Problem
A cloud engineering team was spending time on repeat troubleshooting that needed senior escalation.
What we did
We automated repeat troubleshooting steps, wrote runbooks and trained the team on change control.
Result
Front-line engineers closed more issues on their own, and delivery efficiency went up.
Security

Operating 200+ enterprise systems securely

Problem
A large environment needed to stay scalable, secure and running, with clear escalation to voice and technical vendors.
What we did
We oversaw 200+ enterprise systems with security monitoring protocols and monitoring and alert workflows.
Result
Operational continuity, with security issues detected and escalated through defined workflows.
