Modernize the systems your operations depend on.
Remove processing bottlenecks and make complex software easier to change, with careful validation at each step. Sorrell Consulting connects assessment and architecture with hands-on implementation.
Engineering for commercial organizations and government programs.
Selected results
From Sorrell Consulting’s commercial engagements.
Required upstream processing typically completed within minutes of the daily cutoff, with data ready when scheduled downstream workflows began.

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.
Engineering capabilities
Architecture and modernization
Understand what needs to change and carry a practical migration plan through implementation.
Explore architectureCloud and distributed systems
Build and improve services and processing platforms that teams can operate, diagnose, and recover.
Explore distributed systemsData engineering and computational software
Make data available when it is needed, reconcile conflicting inputs, and improve demanding processing workloads.
Explore computational softwareEngineering reference
Amends
Keeping derived results correct when historical records change.
A correction to an earlier business record can invalidate results that have already been published. Amends is an open-source reference implementation demonstrating how to repair affected results, withdraw obsolete outputs, recover from interruptions, and independently verify the outcome.
Founder background
Senior engineering judgment, carried through delivery.
Joshua Sorrell, founder and principal engineer, leads the work. His background spans commercial software, defense research, and Army mission support.
