Our Featured Back-End Case Study

We partnered with a leading player in the digital transformation and sales engagement industry and helped enhance their capabilities by implementing an advanced analytics subsystem. This subsystem aimed to enable the system to collect, store, and analyze extensive volumes of data, empowering them to make data-driven decisions and provide better services to their clients.

Complexity of Data Management

One of the primary challenges was the complexity of managing and processing large datasets. Our partner needed to plan meticulously and implement a solution capable of handling the substantial data influx efficiently. They transitioned from using SQL-based storage (MySQL DB) to a big data solution (Amazon Redshift) to ensure higher performance and more streamlined data processing.

Integration with Existing Systems

Integrating the new analytics subsystem with the existing systems and applications posed another significant challenge. Careful consideration was required to ensure a seamless transition that would not disrupt ongoing operations. To address this, the development team followed the CORS pattern and built an asynchronous analytics processing system based on a message bus and container-based handlers, enabling efficient analytics processing.

The collaboration with our team resulted in the successful implementation of these solutions, enhancing their data capabilities and positioning them for greater success in the digital transformation and sales engagement industry.


With ClearSlide, uptime was crucial because it was really important that the product worked, was fully available to our customer, and kept a service-level agreement. Techstack was able to keep our uptime and our customers happy, and we were able to make sure that our product was always functioning and working for our customers.
