What I'm looking for

I'm looking to build scalable backend applications while growing in cloud services, DevOps, CI/CD, and open-source development.

I'm building scalable backend services at Betopia Group using Node.js, NestJS, PostgreSQL, and Prisma ORM. I containerize applications with Docker and manage deployments across AWS and VPS environments.

Previously at QUPS, I performed manual and automated testing, created test cases and defect reports, and worked with backend developers to validate APIs and system workflows.

I've built an e-commerce backend with multi-role access, JWT authentication, Stripe payments, Firebase notifications, and RESTful APIs. I'm also developing a collaborative project management application with NestJS, PostgreSQL, Socket.IO, and Redis for real-time updates.

I enjoy competitive programming, algorithmic problem solving, scalable application development, cloud services, DevOps, CI/CD, and contributing to open-source and personal projects.
