About
Software engineering with hands-on infrastructure experience.
I work across the full production lifecycle—from application architecture and backend development to server operations, networking, security and incident recovery.
Technical Focus
Production systems that need to be secure, maintainable and reliable under real-world operational pressure.

SMS Platforms
I began working with computers at an early age and developed that interest into professional work across software engineering, telecom platforms, hosting infrastructure and network operations.
I have worked with multiple international and Chinese SMS platform companies on development, integrations and platform operations where API connectivity, traffic handling, reliability and uptime are critical.
Today, I work with Delivery My Motor, a UK-based vehicle delivery service, while also running Hexazn, a hosting and cloud services company. I also support multiple businesses through freelance development, technical consulting and infrastructure work.
Running production hosting infrastructure has given me practical experience with server hardening, malware remediation, firewall management, network administration, cyberattack mitigation, backups, service recovery and incident response. That operational perspective directly influences how I design and build software.
