I build high-performance SaaS and web products with React, TypeScript, PHP, and AI-augmented engineering.
VietnamWhat I'm looking for
I turn complex SaaS designs and business requirements into production-ready web applications. At Dela Security, I transformed a security product from raw concepts into a high-performance live application while integrating frontend architecture with backend services.
I use Claude Code, OpenCode, spec-driven development, and advanced prompting to accelerate delivery and strengthen code quality. I’ve applied these AI-augmented engineering practices to reduce time-to-market for complex product features.
At Del-Qui and DATAFLUCT International, I delivered frontend and backend features across diverse client architectures and helped take an in-house product from design through production release.
My background also includes PHP, WordPress, e-commerce, SEM, and web infrastructure. I’ve built digital sales channels, internal tools, marketing landing pages, and automated data workflows from setup through deployment.
