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.

A simplified public version of an existing privately operated beekeeping application. Explore colony inspections, follow-ups and traceable relocations using synthetic browser-local data. The separate local Node.js/SQLite API demonstrates transactional writes and automated tests.
