Back to original languageAbout Ivan
Are you looking for an experienced frontend architect who not only writes code but also strategically develops your architecture? Then I am the right contact person.
As a Lead Frontend Architect with over 15 years of experience in business-critical projects – from the Deutsche Bundesbank and BaFin to DZ BANK – I combine technical depth with strategic foresight and the ability to communicate architectures clearly.
My current focus is on modern Angular (Zoneless, NgRx Signals, OnPush), monorepo architectures, and the design of scalable component libraries. At DZ BANK, I am responsible for the frontend architecture of a blockchain-based securities platform: monorepo migration of two independent frontends, role-based authorization concepts, and state machine modeling of complex business processes.
What makes me special: I bridge the gap between business departments and development. I model processes using swimlane diagrams and state machines, provide technical leadership to external and internal developers, and distill architectures to their essence – for developers and stakeholders alike.
I can support you with:
- Angular architectures (Standalone, Zoneless, Signals, OnPush, Monorepo)
- Role-based authorization concepts and complex UI flows
- Technical leadership, code reviews, and mentoring
- Blockchain frontends (Ripple, Ethereum, Solana)
Backend integration (Spring Boot, Kubernetes, Microservices)
- Certified as iSAQB Software Architect, Scrum Master, and Product Owner.
Do you have an ambitious Angular project or a challenging architectural decision? I look forward to your inquiry.
