Describe the scope of work in detail. Please include a summary of key deliverables.
Techstack’s team started by conducting a full audit of the system, which immediately highlighted critical flaws that were causing instability. From there, they rebuilt the subsystem step by step. They fixed logging issues, redesigned the backend logic, and introduced a more efficient microservices architecture. They also migrated us to a modern big data infrastructure with Amazon Redshift, ensuring we could handle parallel processing at scale. On top of that, their team integrated our platform seamlessly with AWS and set up synchronization with third-party CRMs like Salesforce and MS Dynamics.
RESULTS & FEEDBACK

System performance improved dramatically, dataset retrieval times were reduced, and analytics processing became faster and more reliable. The user experience was also completely reworked, making it easier for our team to engage with the data and draw meaningful insights. These changes not only helped us serve existing clients better but also positioned the platform to attract more users and remain competitive in a very demanding market.
