SOFTWARE ENGINEERING · CHRISTCHURCH, NEW ZEALAND
Pawel Firsowicz
Software Engineer | Backend Systems, APIs & Systems Integration
I develop backend systems, APIs and integrations that connect applications and data. Alongside my professional work, I build independent software products focused on practical problems and real-world workflows.
01 / ABOUT
Engineering useful software
My interests span backend development, system integration, full-stack applications and deployment operations. I value maintainable architectures, reliable data handling, automation and software that remains useful beyond the initial release.
02 / SELECTED WORK
Independent projects
Public engineering demonstrations built with synthetic data. These are separate from private production applications.
01 / WATER ALLOWANCE
Water Allowance Tracker
Explore meter-reading workflows, allowance calculations and consumption reporting in a synthetic browser-local demo. The repository also contains a separate Node.js, Express and MySQL application demonstrating API design, validation, database integration and automated tests.
