Enterprise B2B & GovTech Workspace

Audit & Matching EngineSoll/Ist Schedule Builder

7-Step Wizard~~Multi-criteria matching~~

Deviation Audit~~100% State compliance~~

Token Architecture~~Light/Dark & Status tokens~~

Multi-criteria matching engine evaluates availability, skills, and geography dynamically.

Automated Soll/Ist (planned vs. actual) deviation audit ensures 100% state compliance.

3-tier paperless audit signature workflow with mobile canvas integration for field staff.

Outcome

100% Audit Accuracy · 50% Review Time Reduction

Architecting a 5-sided GovTech ERP platform for German social care coordination required mapping strict regulatory constraints into scalable UI patterns. The primary challenge was replacing manual paper-based scheduling and time-tracking with an automated, state-compliant digital workflow while supporting multi-tenant role privileges.

I built a tokenized multi-theme design system in Figma (Auto-Layout, status tokens, light/dark modes) that unified the enterprise ERP with a confidential AI No-Code SaaS platform. We automated planned vs. actual (Soll/Ist) deviation auditing, eliminating compliance risk for state sponsors.

Unping Collaborative Workspace

Active Rooms4 Workspaces & Huddles

Huddle Room A~~12 members active~~

Guest Lobby~~4 pending handshakes~~

Floating Mode Widget~~Always-on-top dock~~

Responsive room layouts calculate cell sizes and focus states dynamically.

Spontaneous audio/video huddles launch instantly without calendar constraints.

Lobby queues separate guest handshakes from secure internal huddle zones.

Unping is a collaborative virtual workplace for distributed engineering squads. Standard video calls triggered calendar fatigue and administrative overhead. People wanted spontaneous huddles that felt like turning around in a physical office. The brief was to architect a friction-free spatial environment.

Usability tests confirmed that remote teams did not want infinite canvas maps where they had to manually drag avatars around. They wanted structured room slots with deterministic connection states. We designed an always-on-top desktop widget ("Floating Mode") and mapped WebRTC handshaking queues into deterministic grid cards.
