Why Re-Engineering Can’t Wait
$1 billion invested in digital resilience
Global organizations collectively invest over $1 billion in digital resilience, revamping applications to withstand disruption, boost security, and improve scalability. Application re-engineering is key to enabling modern, cloud-native architectures like microservices.
68% of companies advance multi-skilled teams
68% of companies are re-engineering their development practices by building multi-skilled DevOps and Agile teams. This shift improves software delivery, flexibility, and collaboration, making modernized application environments more efficient and resilient.
78% of companies plan to operate across multiple sites
As 78% of enterprises adopt multi-location models, applications must be re-engineered for distributed operations. Scalable, cloud-ready systems support seamless workflows across geographies, ensuring performance and reliability in hybrid setups.
$1.6 billion lost to inefficiencies
Inefficient systems could cost businesses up to $1.6 billion in lost revenue. Re-engineering helps remove bottlenecks, streamline workflows, and optimize UX, unlocking new value, improving performance, and accelerating competitiveness.
70% of IT budgets are tied to legacy systems
Nearly 70% of IT budgets still go toward maintaining outdated systems. Application re-engineering reduces this burden by replacing legacy code with scalable, efficient solutions, freeing resources for innovation and growth.
30% of companies struggle with cloud overspending
30% of organizations face post-migration inefficiencies in cloud spend. Re-engineering cloud applications helps optimize architecture, align usage with business needs, and cut operational costs, ensuring cloud investments pay off.

Emerline is an important part of our strategic team!

Emerline provides high quality work, so much so that our platform's reliability and accuracy has been mentioned by our largest customer's internal vendor survey repeatedly.

My experience with Emerline has been great
The team was hired to design and develop the Echospectra mobile and web applications, as well as to integrate them with a variety of cloud services. A critical requirement was to rapidly develop the apps in an agile manner, quickly implementing important stakeholder and user feedback as it came along, and fixing any outstanding bugs. The team managed to accommodate this kind of agile, change-driven process successfully. Thanks to their rapid development approach, we've been able to build the initial app versions and then continuously iterate on them to refine our product offering and make sure it meets and exceeds customer expectations. I highly recommend them to anyone looking for a reliable partner who delivers on time and on budget.
