01 / About

From requirements and data
to understandable systems.

My systems analysis experience is backed by hands-on production support: requirements, SQL, REST APIs, testing and incident investigation. This helps me understand a system both before release and when real users work with it.

My academic background is Applied Mathematics and Computer Science. In practice, I separate observed facts, hypotheses and conclusions so that problems are easier to reproduce, investigate and explain to the team.

I work with PostgreSQL, MariaDB, Microsoft SQL Server and SQLite, REST APIs, Python and diagnostic tooling. I also have experience modelling AS-IS / TO-BE processes, designing data structures and preparing technical documentation.

I have also studied advanced Python and SQL; my academic projects and thesis are available on GitHub ↗.

Analyst Intern · Business Application Support

I work with incidents and changes in corporate applications, from checking a user scenario to narrowing down the likely cause and providing developers with reproducible technical context.

  • Investigate incidents by reproducing scenarios, comparing API behaviour, logs and data, and narrowing down likely causes.
  • Validate data and system scenarios with SQL, Python, REST APIs and command-line tools.
  • Write and maintain regression tests for FastAPI APIs, including positive, negative and boundary scenarios.
  • Provide developers with reproducible technical context: steps, input data, logs, expected and observed results.
