Senior software engineer specializing in secure legacy modernization, microservices, and DevSecOps automation.
IrelandWhat I'm looking for
I’m a Senior Software Engineer with 25+ years of experience specializing in secure application architecture, high-availability systems, and legacy modernization. I treat PHP, Python, and Go as tools to solve complex business problems—prioritizing architecture, security, and scalability over syntax.
I combine deep Linux infrastructure experience (20+ years) with recent certifications in Ethical Hacking & Cybersecurity, so I can turn fragile systems into robust, secure Microservices and Laravel architectures without operational downtime. In my recent work, I’ve led enterprise-scale refactoring to strict Laravel 12 architecture and added centralized policy/permission authorization to reduce the attack surface.
I’m a hands-on technical leader who standardizes DevSecOps workflows, automates testing cycles, and integrates AI-driven solutions to reduce technical debt and accelerate delivery. From building autonomous AI agent tooling (Vibe Coding) to modernizing legacy codebases and improving reliability, performance, and developer experience, I consistently focus on secure engineering practices, spec-driven development, and operational excellence.
