Legacy System Modernization

Create agile, secure, and scalable platforms from legacy systems to future-proof your business. We modernize mission-critical applications so you can innovate without old code, brittle architecture, or hidden operational costs at Cogent Devs.

So why modernize?

Legacy apps are often stifling. We fix common issues:

1. Maintenance and operations are expensive
2. Poor scalability and time-to-market
3. Security and compliance issues
4. Modern API and tool incompatibility
5. Poor usability and slow performance

Modernization boosts business value with faster releases, better security, lower TCO, and integration with modern apps and ecosystems.

Our pragmatic approach — not “lift & shift”

1. Evaluation and Approach

   We map your business objectives, technical debt, and architecture before developing a prioritized modernization roadmap that includes long-term re-architecture, migration lanes, and quick wins.

2. Microservices and Re-architecture

   We divide monoliths into modular, independently deployable services when necessary to increase resilience and spur innovation.

3. Refactoring and optimizing code

   In order to decrease errors, enhance maintainability, and boost developer efficiency, we clean, simplify, and test important code paths.

4. Enabling and Integrating APIs

   We make it possible for you to integrate with new platforms, partners, and micro-frontends by exposing legacy functionality through reliable, documented APIs.

5. Cloud Migration & Readiness

   IaaS, PaaS, containers, or serverless—we move you where it makes sense with cloud-native patterns, automated deployments, and elastic infrastructure.

6. Modernization of UI/UX

   Improved workflows combined with modern interfaces make users happier.  We revamp front-ends to increase conversion, speed, and accessibility.

7. Compliance & Security

   Modernization involves adhering to industry standards and regulations for threat modeling, secure design, encryption, and audits.

8. Automation, Continuous Improvement, and Monitoring

   Automated testing, CI/CD, and observability keep your modern platform robust and evolving over time.
