A multi-tenant POS and F&B management platform connecting restaurant ordering, reservations, kitchen operations, billing, and payments.
Role and ownership
Worked as a Full-stack Engineer at Dan Solutions in a five-person team, extending the existing web app across frontend screens and backend APIs. Owned receipt printing, takeaway ordering, advance reservations, and payment modules.
Verified outcomes
Implemented 13 API endpoints and four React/TypeScript screens: receipt printing, reservation forms, reservation lists, and payments. Delivered these features into the existing production application.
Built multi-tenant reservation forms with sessions bound to restaurant domains, allowing the same form flow to serve multiple restaurants. Connected booking submissions to backend services and administrative reservation lists, and extended takeaway ordering, bill splitting, payments, and kitchen-screen workflows.
Supported a senior engineer on tenant-aware permissions and tenant switching in a PostgreSQL architecture with separate databases and schemas, connecting users to their authorized restaurant environments.
Refactored reservation and receipt forms from development into main through code review, contributed CI configuration updates, and resolved production bugs reported by Czech restaurant customers.
The challenge
Extend a live restaurant platform where bookings, orders, kitchen screens, and billing need to work together, while preserving permissions and tenant context across separate restaurant environments.
The approach
Delivered the assigned modules across the React administration app and backend APIs. The reservation form used sessions tied to restaurant domains, allowing reuse across tenants while booking submissions fed the administrative reservation list. Receipt, split-bill, payment, and kitchen changes connected operational workflows. Tenant permissions and switching were implemented alongside a senior engineer, with code review and customer bug fixes supporting release.
