Swiss tax pricing varies by canton, civil status, income type, and a long list of possible deductions, making it hard to give individuals an honest price before any work starts.

Built a rules-based calculator that turns a short questionnaire into a guaranteed, itemised quote across three service tiers, in minutes and without creating an account.

Tax filing means moving sensitive personal and financial documents between clients, advisors, and administrators without exposing them.

Built encrypted, role-based document storage with a ticket-based messaging system, backed by dedicated web and security audits using Suricata and ModSecurity.

A single tax return passes through several hands (client, advisor, administrator), and status needed to stay visible to everyone without a flood of manual emails.

Built a status-tracked workflow covering file preparation through submission and objection handling, with automatic email updates at each step and a super-user console for advisors to manage their caseload.

The platform needed to hold up under the traffic spikes that come with tax season, not just everyday use.

Built with server-side rendering and a fully responsive front end engineered to handle over 100,000 requests per minute.
