Backend & web developer

I build web applications, REST APIs and data pipelines. At GISTDA, Thailand’s space agency, I shipped a search app over more than a million satellite scenes.

About

I am a backend and web developer with 9 months of hands-on experience at GISTDA, building web applications, REST APIs, databases and automated data pipelines with Python and JavaScript.

My work has ranged from a Node.js/Express search app and a Flask back end with Google OAuth and Docker to debugging satellite-image processing pipelines. I also work productively with AI-assisted development tools such as Claude Code.

Experience

  1. Programmer · GISTDA

    May 2026 – Aug 2026

    Calibration/Validation and Surface Reflectance Analysis Ready Data (SR-ARD) Project

    • Built a full-stack STAC search web app over 1M+ THEOS scenes in the National Space Data Center, with filtering by area, date, processing level and cloud cover.
    • Debugged and extended a Python SR-ARD pipeline with Kasetsart University: added a 3-tier fallback for atmospheric inputs, integrated Copernicus CAMS data and recovered 5–10 previously unusable images.
    • Automated metadata correction to CEOS-ARD specifications across 100+ images, saving 100+ hours of manual editing.
    • Designed logging, email-alert and input-folder specifications for the Cal/Val system; tested 6 modules and benchmarked SR-ARD processing time.
    • Automated Sentinel-2 basemap downloads and mosaicking, and tuned geometric correction to an RMSE below 7.5 m.
    • Created a parallel TIFF-to-PNG batch converter for Earth Gallery that exports 300-DPI images with previews under 5 MB.

  2. Programmer Intern · GISTDA

    Nov 2025 – Mar 2026

    Cal/Val Team

    • Built the back end of iDAR, a satellite pointing-accuracy web app, in a 2-person team: modular Flask, Google OAuth, and a SQLAlchemy/SQLite schema.
    • Wrote parsers that reduced storage by 99.5%, from 2.78 GB to 13.1 MB.
    • Automated dashboards, Plotly maps and .docx reports, cutting reporting from about 30 minutes to 10–15, and containerized the app with Docker.
    • Ran daily THEOS-2 pointing-accuracy checks and wrote the operations manual.

Freelance work

I take on small to medium projects in the areas I already work in:

  • Web apps & REST APIs

    Back ends and internal tools with Flask or Node.js, including login and databases.

  • Workflow automation

    Scripts that replace repetitive work such as file conversion, data cleaning and report generation.

  • Dashboards & reports

    Interactive dashboards and automated reports with Plotly, Chart.js or Power BI.

  • Map & geospatial apps

    Map interfaces and data search with Leaflet.js, QGIS and STAC.
