Hey, I am Vishmayraj. I am a backend engineer and a B.E. Computer Engineering student at Gujarat Technological University in Ahmedabad, India (2024 to 2028). I like building things where the data does not just sit still: ETL pipelines, geospatial infrastructure, real-time APIs, the kind of systems that have to keep working while stuff is actively happening to them. This year I got selected for GSoC 2026 with OSGeo, as a second year student, which still feels a little surreal to say out loud. I built a metadata connector that bridges the OGC SensorThings API to STAC and DCAT-AP 3.0, so sensor data stops being stuck inside one system and becomes something geospatial browsers and EU open data portals can actually find and use. Right now I am writing up the connector as a research paper. After that, I want to build a portfolio site in Phaser, mostly because it sounds fun. |

Final product and full writeup
This is the one I am most proud of. I built a FastAPI service that pulls metadata out of istSOS4 through the OGC SensorThings API and turns it into STAC 1.0 and DCAT-AP 3.0 catalogs, so sensor observation data stops being stuck in one silo and becomes something geospatial catalog browsers and EU open data portals can actually pick up and use. Implementation is complete: 37 out of 37 connector tests passing, output validated against the official STAC and DCAT-AP 3.0 SHACL shapes, and stress tested against a 5,600-Thing dataset. Submitted upstream as four pull requests, currently under review.
