Expert PHP & MySQL Programmer / Linux Administrator

As an IT expert with 25 years of experience, my primary goal is to deliver optimal technical solutions to each client, ranging from simple consultations to fully optimized products and services. Passionate about software architecture, code refactoring, adapting PHP scripts from lower PHP versions (5.6, 7.X) to the latest (8.X), and updating and fixing running sites to newer software/framework versions. I adhere to K.I.S.S. principles (keep it stupid simple) and specialize in customized optimized APIs, hundreds of different API integrations. I mostly work in Linux server optimizations for specific hardware (Kernel optimizations) and the customized configuration of services (without cPanel) such as Apache/Nginx, SSL certificates, PHP add-ons compilation, MySQL/MariaDB/Galera optimizations, security hardening, mail server (comply with all rules to deliver at inbox), VPNs, DNS, and custom logging. I also provide customized services and setups for FreeSwitch PBX, including special solutions like cold IVR message delivery and multi-tenant routing. With extensive experience in networks, I am proficient in load balancing, network security, and VPN setups. I work independently or as part of a team using agile methodologies (Scrum certified), with a strong focus on details and communication. I am flexible with communication channels and will provide my email address, Skype, or phone number as needed to ensure effective collaboration. Most of my work has been done under NDA contracts, so I cannot provide public references.
