What I'm looking for

I'm seeking a Backend-focused Full Stack Software Engineer position where I can apply my experience with Node.js, NestJS, PostgreSQL, Redis, Docker, GCP, and RESTful API development. I want to build scalable, reliable applications while expanding my skills in React, Vue.js, cloud technologies, and modern full-stack development.

At Realtech Company Limited, I built and maintained NestJS services and REST API endpoints supporting web and mobile applications.

I improved database efficiency with indexing and query optimization, and added Redis caching that reduced repeated database queries and improved response times by approximately 20–30%.

I also integrated third-party payment gateways and implemented GitLab CI/CD pipelines that reduced manual deployment steps by approximately 50%. I added Jest tests and supported Vue.js interface updates connected to backend APIs.

Earlier, as a Web Developer Intern at Bangkok Web Solution, I delivered feature updates and bug fixes for a PHP web application and worked with designers and backend developers on responsive client sites.
