01 — Profile

About me

I work at the intersection of business and engineering. As a System Analyst I gather requirements directly from customers and turn them into URS, SRS, and functional / non-functional specifications; as a developer I then build the system that satisfies them. That end-to-end view is what I enjoy most — understanding a process, designing the right data model and API, and shipping software people actually use.

My coursework and certifications cover cloud application development, cloud architecture, and big data & machine learning, so I am comfortable working with data pipelines, analytics, and AI-assisted features as well as classic web and mobile development. I study in an international program, so I document, present, and collaborate fluently in both English and Thai.

I care about doing things properly: version control and code review on GitHub, automated CI/CD, unit testing, and UX validated in Figma before a single line of production code is written.
