Read the modernization case studyOn Sorrell Consulting’s engagement at Citadel
Joshua is one of the strongest engineers I’ve worked with. At Citadel, he had a rare ability to understand the business as deeply as the technology, and he became the go-to person for one of our most complex and critical fund accounting platforms. He could debug, optimize, and build on highly complex systems with a level of confidence and reliability that few engineers could match.
When to bring Sorrell Consulting in
Processing delays are holding up other work.
A batch window, computation, or dependency leaves people and downstream systems waiting.
The system needs to change, but too much depends on it.
The team needs a migration path that accounts for existing behavior, dependencies, and operational constraints.
Failures take too long to diagnose and recover from.
The system needs clearer visibility and recovery behavior so operators can understand and resolve incomplete work.
The modernization path isn't clear enough to commit to.
The team needs an experienced engineer to evaluate options and carry the chosen approach through implementation.
