Juan Pablo Bacallao Castillo

• Designed and built from scratch a topological network model and rendering algorithm that separates every line sharing a street; city-scale networks render in seconds in the browser (Web Workers). • Senior member of a 6-developer team: specifications, architecture, code and design reviews. • Drove the team's adoption of AI-assisted, spec-driven development: sprint velocity rose ~50%. • Built an MCP server PoC (NestJS) to query and edit scenario data through AI agents.

• Built an indoor navigation module for the "Shopping Mall" mobile app, integrating third-party indoor maps and positioning (Lazarillo Maps SDK) to route users to destinations.

• Hands-on tech lead: production code, technical direction, reviews and mentoring. • Defined the microservices architecture for national healthcare systems during COVID-19, incl. clinical-trial management for the Abdala and Soberana vaccines. • Designed a low-code platform generating database, REST API, grids and forms from spatial models; cut delivery of new GIS apps to weeks. • Built Linear Referencing / dynamic segmentation for the Ministry of Transport road inventory.

• Developed Genesig, the in-house GIS application framework underpinning multiple geospatial products across the organization. • Built a data-driven thematic map module and a PDF report builder with embedded map content. • Contributed to a geospatial import/export module (GDAL/OGR) and a shared UI component library used by all Genesig-based applications.
