The client

SASR Workforce Solutions is a recruiting and staffing platform designed to enable professionals to assist with rapidly changing working environments. The SASR Workforce mission is to connect great people with great companies to positively impact the workforce nationwide.

Working with the Tizbi dedicated dev team, SASR Workforce enhanced and modernized the existing legacy system platform and integrated new microservices into its software. Beyond legacy system modernization, our clients aimed to automate as many internal processes as possible, improve efficiency, and reduce manual workloads for system users.


The challenge

Legacy system modernization and microservices integration

Legacy systems always present many challenges, from the clashing of new and old software components to the complex knowledge transfer process.

The existing platform required updates to effectively integrate with modern tools and frameworks. Our dedicated dev team took time to understand the pre-existing architecture to successfully update the system without disrupting ongoing operations.

Integrating new microservices required careful planning for similar reasons tied to the legacy system. The new microservices were built with a modern tech stack. Our dedicated dev team ensured compatibility between the new and old components despite the difficulties posed by working with a legacy system

Another challenge faced by the development team revolved around the knowledge transfer process. This process was made more difficult due to the legacy system's size, complexity, and specialized terminology.

Managing technical debt and third-party payroll systems

Additional problems involved the substantial accumulation of technical debt due to the legacy system. This debt made implementing updates and maintaining the system more challenging, as older solutions often conflicted with modern development practices.

Lastly, the client faced challenges related to third-party payroll systems. The payroll systems created roadblocks for the development team, forcing them to work around constraints and address inconsistencies.

Tizbi Solution

The knowledge transfer process

Despite the difficulties, our team of dedicated developers handled every hurdle and successfully implemented the software goals of SASR Workforce.

First, Tizbi's developers invested additional time in working closely with the client's previous team to address the knowledge transfer issue. It was a necessary step due to the size and complexity of the legacy system.

By conducting regular sync-up meetings between teams, this collaboration created comprehensive documentation and ensured the transition went as smoothly as possible. Peaceful collaboration minimized gaps in understanding and enabled a more efficient onboarding process for the Tizbi team.

Legacy system modernization

Tizbi software developers designed a microservices-based architecture to enhance the system's scalability and efficiency. The improvements enabled a smooth integration of new functionalities and fortified the platform's adaptability to future updates.

Our development team provided 24/7 support to ensure uninterrupted operations and efficient implementations of the software updates. This round-the-clock support ensured that issues arising during the transition phase of the legacy system modernization process were resolved immediately

To address the technical debt, we systematically prioritized and resolved issues, ultimately stabilizing the legacy system. This approach ensured that the most critical problems were tackled first, minimizing disruptions and improving the platform's overall reliability.
