Tuan Nguyen Email & Phone Number

Hi, I'm Tuan and I'm a person who works in the software industry, specifically, telecommunication software for end-users like Call Centers and PBX.I have been working in this industry since June 2019, it's almost 3 years by the time I write this, the first 2 years are for me to get to know Linux and VoIP Systems, understand the customer's perspective, and what they expect from a software provider, from then on I am using or trying to use DevOps tools to improve the lives of many VoIP Engineers / System Admins in my team. Right now, I am learning more and more about infrastructure and architecture every day to build a scalable and sustainable infrastructure using DevOps tools to fully automate it via IaC.I have many experiences with Linux OS, Services run on Linux OS (Apache2, Nginx, MariaDB, PostgreSQL, HAProxy, Corosync, Pacemaker, Zabbix, ...), and VoIP Service / VoIP Systems (Asterisk - FreePBX, FreeSWITCH - FusionPBX, Kamailio / OpenSIPs, Homer, GOautodial, SIPP). I also have some experience and knowledge with some DevOps tools such as Jenkins, Ansible, Docker, Kubernetes, Vagrant, and Terraform to help me automate many aspects of a system admin and more, such as deployment, monitoring, migrate data, backup / restore, load test / stress test, scale up / scale down based on user volume, ...By the time I write this, March 2022, I can build a VoIP infrastructure using OpenSIPs - FreeSWITCH - PostgreSQL - Nginx - HAProxy load test with 5000 users & 1200 concurrent calls using SIP continuously for many days, fully deploy via Jenkins - Ansible.My final goal is to create a scalable and sustainable infrastructure that can withhold up to hundreds of million users and be known as the person behind that system. I once heard; musicians don't retire, they stop when there's no more music in them; and I still have a lot of music to offer. So please, contact me if you have any interesting projects or problems to offer.
