About

I have a technical background in software development and currently focus on data analysis, data systems, automation, and geospatial applications.

My earlier work gave me experience with application development, databases, APIs, and structured software workflows. Over time, my focus shifted increasingly toward data: how it is collected, structured, validated, analysed, and turned into reliable outputs.

My studies in environmental data have added another dimension to that work. They introduced me to statistical analysis, spatial data, GIS-related problems, and the use of data for understanding real-world systems.

Today, I bring those areas together through projects that combine analytics with stronger technical foundations: SQL data models, automated workflows, data-quality checks, reproducible analysis, and geospatial processing.

Current Focus

Data Analysis

Turning raw datasets into meaningful metrics, comparisons, and decision-ready reporting.

Data Systems

Structuring data flows, models, transformations, and reusable analytical layers.

Automation & Reliability

Reducing manual work through repeatable workflows, validation, testing, and monitoring.

Geospatial Applications

Using spatial data and GIS techniques for accessibility, infrastructure, and environmental patterns.

How I Work

  1. Source
  2. Validate
  3. Model
  4. Analyse
  5. Deliver

I prefer projects where analysis is part of a complete data workflow rather than an isolated notebook or dashboard.

That usually means understanding the source data, validating its quality, modelling it appropriately, analysing the problem, and producing an output that can be reproduced and explained.

I also try to make limitations explicit. A useful analysis should show not only what the data supports, but also where the evidence stops.

What I'm Looking For

I'm interested in roles where I can work with data while continuing to deepen the technical side of analytics — particularly data systems, automation, operational analytics, and geospatial data.

My portfolio focuses on practical projects that demonstrate those capabilities through working systems, analytical models, and documented case studies.
