Senior Software Engineer | Legacy Code Remediation Specialist

Based in Richmond Hill, Ontario, I bring over 20 years of experience in modernizing legacy architectures towards API-centric ecosystems. I specialize in turning chaotic, aging software systems into reliable, scalable platforms.

Currently, I work as a Senior Full Stack Developer at RBC and run CodeJanitor, a consultancy for distressed PHP/Laravel codebases.

I don't just write code; I solve structural problems. My career has been defined by taking "LAMP stack" monoliths and transforming them into scalable microservices on Azure and Kubernetes.

• Complex Migrations: Expert in moving legacy infrastructure to modern cloud environments without downtime.
• High Performance: Proven track record optimizing systems handling 500,000+ daily transactions.
• Security First: Deep expertise in PCI-DSS compliance and banking security standards.

Detailed metrics from my career at RBC, Midtown Capital, and Anyda:

• High-Volume Optimization: Architected MySQL databases processing 500,000+ daily transactions, improving query performance by 30% at Midtown Capital.
• Payment Systems: Built PCI-DSS compliant payment architectures handling $8M+ USD annually with a 99.8% transactional success rate.
• Availability: Engineered scalable platforms serving 200,000+ monthly users while guaranteeing 99.95% uptime.

• Cloud Architecture: Designing enterprise Laravel applications for RBC PayEdge, deploying workloads to Microsoft Azure using Docker and Kubernetes.
• Latency Reduction: Reduced API response latencies by 75% through strategic Redis implementation and microservice integration (Java/Node.js/Kafka).
• Efficiency: Led Agile teams to reduce delivery cycles by 40%, ensuring rapid deployment without breaking production.
