What I'm looking for

I’m looking for a role where I can build and operate GIS solutions end-to-end—spatial validation, server/web mapping, and Python/PostGIS automation—while collaborating across teams to deliver reliable geospatial insights.

I’m a Geographic Information System (GIS) Analyst with hands-on experience validating, updating, and correcting geospatial datasets to support Water Resources Data management and spatial decision-making across directorates.

In my recent work, I architected an independent GIS Server using PostGIS, GeoServer, and Python (Flask), earning 2nd Place in the Geospatial Innovation Competition (Pusdatin - Ministry of Public Works). I also integrated spaCy for natural-language-to-spatial query conversion, including CQL Filter generation and multi-theme layer management.

I’ve repeatedly led field-to-data workflows, including river geometry correction, adding new river networks according to Ministry standards, and coordinating with stakeholders to provide spatial insights on locations, infrastructure assets, and their correlations.

Beyond GIS analysis, I’ve coordinated and led execution as a Team Leader and Coordinator, overseeing budget management, official reports, field issue logs, and UAV-based aerial photography compliance. Earlier, I worked as a Surveyor performing GNSS point surveys for LIDAR calibration, GCPs, and PPK basepoints, ensuring strong ground-truth and data quality.
