— Approach

  • Delivery-first mindset Working software over comprehensive documentation. I ship, iterate, and improve.
  • Domain-driven design I model the business, not just the data. Deep domain knowledge drives better architecture.
  • Quality built in TDD, code review, and automated pipelines. Quality is not a phase — it's a practice.

Senior leadership,
deep technical roots

I'm Jim Ribi, founder of Vemish Technology Ltd — a Director-level technology leader and product manager with 15+ years architecting and delivering mission-critical platforms for tier-one investment banks.

My career spans several senior roles at Credit Suisse, UBS and CIBC; I've built, owned and scaled global RFQ platforms, pricing engines, and trade lifecycle systems across Equity Flow and Structured Derivatives.

I operate at the intersection of technology strategy and hands-on delivery — equally comfortable defining macro product and platform vision, as I am in the codebase solving specific and complex engineering challenges. I offer a combination of executive-level stakeholder management with genuine technical authority in C#/.NET and derivatives domain expertise.
