Over mij
I'm a Technical Analyst with nearly 5 years of experience in fintech, payment systems, SQL, and REST API integrations. I turn technical requirements into clear, usable deliverables: SQL queries, API documentation, user stories, acceptance criteria, ER diagrams, and database schemas.
I work with SQL Server, Postman, Swagger/OpenAPI, and structured requirements documentation. My focus is on well-defined, one-time projects with accurate, practical outputs and clear scope. I'm also pursuing an MSc in Data Science at TU Wien.
