I've designed backend architectures and scalable REST APIs at Lomax Media, covering authentication, authorization, data access, and business-critical workflows.
I optimized MySQL solutions through indexing and query improvements, increasing database performance by up to 40%. I also built RBAC, administrative platforms, Android integrations, and secure production workflows.
At CSD Head Office, I enhanced enterprise retail modules used across 200+ outlets and built reliable billing and credit transaction workflows. My performance improvements increased system performance by approximately 45% while contributing to 99.9% uptime.
Across fintech, logistics, education, and enterprise applications, I've delivered Laravel, CodeIgniter, PHP, and Node.js backends. I focus on maintainable architecture, reliable transactions, and resolving bottlenecks across application, database, API, and mobile layers.
