SwissBorg

Turning a legal requirement for 700k+ users into a 2-tap check

Context

700K+ users needed to renew their KYC data or SwissBorg could face millions in fines. I designed a self-serve renewal experience and a reusable KYC system to handle compliance at scale.

Results

220k+ renewals in 2 months, zero UX complaints

and engineers no longer change user data by hand in the backend.

SwissBorg - KYC Dashboard

Cutting KYC 2 review time by 50-75% in two weeks, with no backend changes

Context

SwissBorg's compliance agents reviewed Proof of Residence applications in a fragmented, tab-heavy back office with no defined process. I redesigned it into a guided, single-screen review flow in 2 weeks, with no backend capacity.

Results

50-75% faster Proof of Residence reviews

Measured in the first week, with decisions standardised across all agents.

Tax Systems - Alphamap

An award-winning AI tool that cut tax mapping time by 80%
