Ivan Arias Resume — Geologist · Subsurface Data & GIS

I’m Ivan Arias, a geological engineer with more than 14 years of experience in sedimentology, stratigraphy, and subsurface analysis in the energy sector. Throughout that time I used ArcGIS to build geodatabases, join attribute tables, and produce thematic maps supporting my geological work. I’m currently based in the Netherlands, rebuilding hands-on QGIS experience and exploring Python applied to geospatial data.

🪨 Core expertise: Sedimentology, Stratigraphy, ArcGIS (geodatabases, table joins, thematic mapping), QGIS (in progress). 🐍 Supporting tools: Python, SQL, Leaflet, GeoJSON — junior level, verified through bootcamp projects completed without AI assistance.

Open to Geo-data / GIS Technician roles, positions adjacent to geotechnical or subsurface survey work, and entry-level GIS roles in the Netherlands. Spanish citizen — no visa sponsorship required for EU work.

💻 Projects

🛢️ Oil & Gas GIS Web App

App	Web GIS · React + Flask + GeoJSON

• Interactive spatial queries across boreholes, pipelines, and license boundaries.
• Transparency note: specified and directed by me, built with AI coding assistance. I can explain the intended functionality and architecture, but cannot currently debug or modify the code independently without that assistance.

🗺️ Leaflet Vanilla JS Web Map

App	Web GIS · Pure JavaScript

• Lightweight web map built with Leaflet.
• Same transparency note as above: built with AI assistance, not fully independently.

📊 Student Performance Dashboard

App

Blog

Python · Flask · Dash · Plotly

• Interactive dashboard for student grades and performance trends. Bootcamp project, built without AI assistance.

✅ Audits Tool

App

Blog

React · Firebase

• Application for managing audit data, with reporting and export.

🛒 E-Commerce Platform (Flatiron Capstone)

App	React · Flask · Full-Stack

• SPA with authentication, cart, and product management. Bootcamp project (2023), built without AI assistance — the most reliable evidence of my actual independent coding level.

🗄️ Database Tool CLI

Demo	Python · SQLAlchemy · SQLite3 · Click

• CLI for managing geographic entity data. Bootcamp project, built without AI assistance.

Geologist — Sedimentologist & Stratigrapher – PDVSA | Venezuela and Ecuador
2005 – 2019

• 🛰️ 14 years of sedimentology, stratigraphy, and subsurface spatial analysis, using ArcGIS, Petrel, and OpenWorks as supporting tools — not as a GIS analyst function.
• 🧪 Integrated well logs and core data into reservoir characterization models, using seismic sections as reference context rather than performing seismic interpretation myself.
• 🗺️ Built geodatabases and thematic maps in ArcGIS, used by engineering, drilling, and planning teams.
• 🌎 International rotation to PDVSA Ecuador (2013–2015): high-resolution stratigraphic correlations in the Santa Elena Fold Belt and Progreso Basin.
