A Toptal Case Study
Invista, a leading global manufacturer of polymers and fibers, needed to migrate a proprietary business-critical application built on an outdated FORTRAN codebase. Lacking internal expertise, the company faced risks to production efficiency. They turned to Toptal for a managed solution using Toptal’s Managed Delivery model to handle the backend migration.
Toptal assembled a specialized team, including FORTRAN and Python experts, who conducted extensive discovery and built a custom FORTRAN-to-Python transpiler. This approach, coupled with a sophisticated automated testing suite, reduced project implementation costs by 15%. The modernized system is now maintainable by Invista’s internal team, eliminating future outsourcing needs and reducing long-term operational risk.
