Gazprombank Business Online — corporate banking portal
A complete redesign of the corporate banking platform — 80,000+ active business clients moved to the new system without a service window.

Surface
What users see. Identity, motion, UI craft, copy.
Information-dense, but readable. The dashboard prioritises "what changed since you last logged in" — not "what is your total balance". Bulk-payment flow handles 10k rows in CSV without a sweat.

What holds it up. Architecture, contracts, infra, latency.
A microservice mesh inside the bank perimeter, with the public portal as a thin BFF. RBAC down to the field level. Every payment is signed by a hardware token bound to a session.
