Crixus is led by Jermaine Rattray, a software engineer, architect, and technical lead with approximately two decades of experience.
That experience spans banking, healthcare, industrial technology, and long-lived business platforms. It brings a practical understanding of what it takes to build software—and remain accountable as it evolves.
Founded in 2021, Crixus brings that perspective to every engagement: understand the business, make the right technical decisions, and stay close to the implementation.
Explore your goals, constraints, existing systems, and the workflows that matter. Start with context before choosing tools.
Define the approach, implement the critical pieces, and keep decisions connected to the business need.
Document the system, support handover, and establish a foundation that can evolve with your operation.
