Migrating your application from Ext JS, a licensed framework, to an open-source platform offers several advantages. Firstly, it reduces ongoing costs, allowing you to allocate resources more efficiently. Additionally, this migration enables your business to grow and expand by upgrading its systems, resulting in improved data security for your legacy system. It also enhances data acquisition, data analytics, and scalability of analytical reports. Modern systems are known to be more productive and effective, providing a boost to overall performance. Switching to an open-source platform is more affordable compared to Ext JS, and migration simplifies the integration of the newest IT technologies with your existing systems. Moreover, the migration process helps in developing stable, dependable, and trustworthy solutions. By constantly updating your systems to reflect the latest developments, the risk of becoming outdated is significantly reduced.

We offer the option to onboard experts in areas such as Ext JS Framework Architect, QA/Test Automation, Security/Compliance, Cloud, and TechOps (Microservices/Docker/Kubernetes). They seamlessly integrate within your team, filling specific skill gaps for short-term or long-term engagements.
