Initial problem
Customer and operational data lived in Bexio and Atera and had to be maintained separately in both systems. This created duplicate work, inconsistent data, and repeated follow-up questions. Customers also had no direct overview of their contracts, invoices, devices, or reports and had to request this information from the team each time.
Implementation
I conceived and built the cockpit from the ground up, including its product structure, login, tenant isolation, roles and permissions, and the internal and customer-facing workspaces. A React and TypeScript frontend and a Go and PostgreSQL API provide one place for the team to manage customers, products, contracts, invoices, devices, reports, and reconciliations, while customers receive direct access to their own information. Bexio and Atera synchronization, WorkOS authentication, audit logs, background jobs, and permission-scoped AI assistants connect the workflows end to end.

Impact
Verifiable outcomes
Published products, measurements, and before-and-after comparisons make the impact tangible.
123 → 55 KB
Code splitting and lazy loading reduced the gzip-compressed initial bundle by more than half.
5 → 1 request
Customer, members, contacts, onboarding, and team data now load through one aggregated endpoint.
2 workspaces
One login routes users to either internal operations or the customer workspace based on permissions.
What mattered
Separate internal operations and customer self-service workspaces
Customer, product, contract, invoice, device, and report workflows in one system
Bexio and Atera synchronization with explicit reconciliation and conflict states
WorkOS-based authentication, organization isolation, roles, and permissions
Audited background jobs for imports, synchronization, and recurring billing
Permission-scoped AI assistants for internal staff and customers
Insights
The internal operations dashboard with all live customer and personal data anonymized
The permission-scoped internal assistant for customer, device, billing, report, and audit workflows
Technical frame
The technical frame sits at the end on purpose: it shows the engineering substance behind the solution.
