What this portfolio is
The portfolio is organised around 13 core GIS competencies. Each competency covers a practical area of GIS work and explains what the available evidence shows can be done.
Why an evidence-based portfolio
A list of software, courses or completed exercises doesn’t show, by itself, what a person can actually do.
That’s why the portfolio separates the professional-facing competency pages from the detailed technical evidence.
The competency pages explain the capability demonstrated. The technical evidence backs that up with supporting material, such as:
- GIS workflows
- commands and queries
- data inspection
- processing results
- maps and screenshots
- database results
- supporting HTML
- technical explanations
This way, the reader can see both the professional capability and the evidence behind it.
How the evidence is evaluated
Not every activity is treated as proof of professional competence.
A competency is either demonstrated by hands-on work in this portfolio or pending. Where the evidence only partly supports a capability, the page says so in its “Evidence boundaries” section.
Limitations, incomplete work, errors and gaps are stated openly instead of being hidden.
The goal is to keep the claims in the portfolio matched to the evidence available.
Progressive publication
The portfolio is developed and published step by step.
A competency is added to the public portfolio once its supporting work is complete and reviewed. This means the published portfolio reflects the capabilities demonstrated at that stage of development.
The 13-competency framework stays visible even while some competencies are still pending. That way, the portfolio can grow over time without changing its overall structure.
Portfolio structure
The portfolio has two main layers.
Competencies
The Competencies section is the professional-facing layer. It explains what has been demonstrated in each competency and what the available evidence supports.
Technical Evidence
The Technical Evidence section contains the detailed material that supports the competency pages.
This separation keeps the main portfolio focused on professional capability, while still allowing the technical work to be checked in detail.
Evidence boundaries
This portfolio doesn’t claim to demonstrate every GIS or software technology studied or used elsewhere. Claims about practical capability are based only on the evidence in this portfolio. Earlier experience gives context, but it isn’t evidence for a competency unless the work shows it directly. See the profile.
Intended use
This portfolio is meant to give recruiters and other professional readers a clear way to assess current GIS capabilities and the evidence behind them.
It’s a working professional record and will grow as more competencies are completed and verified.
