RÉSUMÉ · YANETH CASTILLO, GISP

The chronology
behind the work.

GIS Analyst working across spatial research, cartography, Web GIS, configuration, documentation, and the systems that keep published work dependable.

PROFILE

I make complicated spatial work understandable & dependable.

My work began in geoscience and spatial analysis, then moved through GIS production, legal-description research, cartographic communication, Web GIS publishing, and configuration-driven applications. My focus is on dependable GIS applications, data integrity, and scalable systems that serve technical, client, and public audiences.

EXPERIENCE

Work in layers.

01

GIS Analyst

LJA Engineering · Dallas, Texas

  • Deliver GIS solutions across transportation, utilities, land development, municipal planning, and regulatory projects, translating complex spatial requirements into reliable datasets, interactive applications, and client-facing deliverables.
  • Reconstruct and validate complex legal boundaries from survey documentation, including a 224.109-acre tract defined by 109 metes-and-bounds courses, identifying a 0.65-acre discrepancy in reference data.
  • Configure and enhance a public-facing Web GIS platform supporting 133 spatial layers, maintaining separate aerial and street-map configurations with structured layer hierarchies, interactive legends, and visibility controls.
  • Develop and maintain ArcGIS Online and Experience Builder applications, incorporating hosted feature services, vector tile layers, Arcade expressions, and access controls to support internal and public-facing workflows.
  • Integrate and troubleshoot municipal infrastructure datasets within enterprise GIS environments, resolving schema incompatibilities, field mapping requirements, coded-value domains, and versioned geodatabase constraints.
02

GIS Analyst

Landpoint · Fort Worth, Texas

  • Developed and improved processes for data collection, integration, quality control, and database updates across GIS production workflows.
  • Worked with GIS users to define needs, assess project requirements, develop conceptual designs, and plan application implementation.
  • Produced spatial analyses, geospatial data, cartographic deliverables, metadata, workflow documentation, and data-conversion specifications.
03

GIS Analyst Intern

Halff · Richardson, Texas

  • Created geospatial data, static maps, and published web maps using spatial analysis, LiDAR, and terrain datasets.
  • Applied data-mining techniques to support machine-learning model training and assisted with data reporting, review, and technical documentation.
04

Geosciences Intern

Fort Hays State University · Hays, Kansas

  • Used GPS and ArcGIS methods for landfill volumetric analysis and supported research into salt dissolution, subsidence, and seismic-reflection patterns.
