and SaaS products — from security monitoring platforms to mobile apps
and cloud POS systems.
WHAT I DO BEST:
• Backend: Java, Spring Boot 3, Vert.x, REST API, MongoDB, Elasticsearch
• Frontend: React, Vue.js, Flutter (iOS/Android)
• DevOps: AWS (S3, CloudFront, EC2), Docker, GitHub Actions CI/CD
• Integrations: PayPal, Firebase, OAuth2, WebSocket real-time
RECENT WORK:
• Built a live SaaS POS system (React + Spring Boot + MongoDB) — deployed
on AWS with CI/CD, billing, multi-branch support
• Fullstack developer on a digital business card & HR platform (Flutter +
Spring Boot + React) with payment integration
• 4+ years on an enterprise SIEM/security monitoring platform (Java/Vert.x,
Elasticsearch, Vue.js) with 15+ micro-modules
I recently launched my own SaaS product solo, using AI-assisted development
to move fast without sacrificing quality. I understand the full product
lifecycle — from architecture to deployment to user-facing features.
My latest work is a live cloud POS SaaS (“Sổ thu chi”) — built solo from architecture to AWS deployment, with billing, multi-branch, and i18n.
