The challenge

Fortisphere ran 17 country cores on legacy mainframe and three regional ERPs, with 4-week change cycles and rising regulatory pressure across DORA, MAS, and OCC.

Our approach

  • Established a single global cloud landing zone on AWS with regional residency overlays.
  • Stood up a migration factory with parallel-run safety nets and automated cutover playbooks.
  • Re-platformed the digital core onto an event-driven architecture with Kafka and Snowflake.
  • Embedded SRE, FinOps, and DevSecOps practices with quarterly maturity uplift KPIs.

The solution

A global cloud foundation, a phased modernization of the digital core, and a managed SRE practice running on shared SLOs.

Parariya brought strategic clarity and execution precision. Their team felt like an extension of our leadership group.Elena Martinez, CIO, Fortisphere Bank

What this means for similar programs

The pattern beneath this engagement is one we apply repeatedly across financial services clients: a phased approach, embedded senior practitioners, and a measurement plan negotiated up front. The result is faster outcomes, fewer surprises, and an operating model your teams can run themselves.
