WHY ORGANIZATIONS CHOOSE US
Toptal in Action
Discover the cutting-edge benefits our clients enjoy from the global Toptal network.
Toptal reduces project implementation costs by 15% while driving strategic modernization for INVISTA.
Challenge: INVISTA needed to migrate a proprietary business-critical application but had no in-house expertise in the outdated FORTRAN codebase. Failure to migrate the database to a modern language meant risking production efficiency.
Solution: INVISTA turned to Toptal to fully manage the back-end migration in close coordination with INVISTA’s front-end team. Toptal conducted extensive discovery to decipher the “black-box” system and formulate a strategic project plan for immediate execution.
Outcome: Toptal developed a sophisticated automated testing suite to validate the precision of the migrated system, giving INVISTA a high level of confidence in the accuracy of the end code. Additionally, by implementing a custom FORTRAN-to-Python transpiler, Toptal reduced project costs by 15%, enabling INVISTA to reinvest in enhanced functionality.
Toptal was an excellent partner in helping us modernize a key platform that enables us to build digital twins of existing and future Nylon 6,6 assets. The legacy FORTRAN codebase limited our ability to make changes. The integrated team that Toptal brought together delivered a great result—on time and under spend forecast—that we are now using to create value for our customers.

Microservices are one of the latest trends in software design. In a microservices architecture, the classic monolithic back-end is substituted by a suite of distributed services. This design allows better separation of responsibilities, easier maintenance, greater flexibility in the choice of technologies for each service, and easier scalability and fault tolerance.
In this article, Toptal Freelance Software Engineer Francisco Temudo guides us in a step-by-step tutorial on how to build a microservices suite using Ruby.
