I'm a Senior Software Engineer with over a decade of experience building and maintaining web-based platforms, including membership systems, customer portals, and analytics dashboards. I’m comfortable working across the full stack — PHP, JavaScript, React, MySQL, and cloud infrastructure — with a focus on keeping production systems stable, secure, and practical to support over time. I’m accustomed to remote collaboration with distributed teams and non-technical stakeholders. I value pragmatic design, thorough testing, and clear communication. I work across the stack—from backend PHP/Node.js to frontend React—designing scalable systems, implementing CI/CD, and helping teams move from legacy to modern technologies. I enjoy collaborating with product managers, QA, and client teams to deliver reliable software and document deployment and troubleshooting steps so others can handle routine maintenance without engineering involvement.
