01 / CONNECT
Scattered information. One connected flow.
From the interface people see to the APIs and data behind it. I connect information where it belongs in geospatial and business systems.

02 / BUILD
Connected ideas become working services.
I build interfaces around real workflows, verify features, and improve what operations reveal. Company projects and personal services carry that process forward.

03 / ARCHIVE
Keep the process. Build on the experience.
I document solved problems and the reasons behind technical choices. Projects and notes grow into a record, while recurring patterns are refined from examples into templates.

SELECTED WORK
Engineering experience through projects
My work spans Web GIS, business systems, legacy maintenance, and personal-service design and operations. Each record explains my scope, technical decisions, and implementation evidence.
Small Public Facility Management System
A Web GIS project connecting facility lookup, inspections, maintenance, compensation, and administrative documents. I developed the Vue/OpenLayers UI and Spring Boot business APIs.
Role · Development Team 2 · Full-stack development: Web GIS, business APIs, and document generation

Internal Integrated System Management
I extended institution/server management, maps, and statistics in an existing React/Spring MVC system, tracing state and data relationships before adding features and fixing operational errors.
Role · Development Team 2 · Frontend/backend feature extension and maintenance of an existing system

Dev Knowledge Base
Shared guidance lives in a Markdown wiki; project status and public descriptions live in the archive database. One MCP connection provides scoped reading, editing, and requested service checks.
- In active personal use for reading shared development guidance and project material through one MCP connection.
- Authorized tokens can edit the wiki and archive with conflict checks, backups, revision history, and auditing.

QGIS repetitive-task automation
Turns QGIS steps you repeat by hand into re-runnable scripts and processing models.
- The same editing, conversion, and export steps are repeated by hand every week
- Results differ by operator, so checking them takes longer than the work itself
QGIS plugin development
Turns repeated work into a dedicated tool inside QGIS so staff can run it without knowing scripting.
- The work is already scripted, but the people who need it cannot run scripts
- Several people have to use the same tool in the same way
