Application modernization services we offer:
Legacy application assessment & consulting
We start by deeply analyzing your legacy systems — evaluating code quality, architecture, dependencies, and integration touchpoints. Our experts help you uncover hidden risks, identify quick wins, and define a modernization roadmap aligned with your business objectives, regulatory requirements, and future scalability needs.
Application rehosting (Lift & Shift)
Ideal for businesses seeking a quick and cost-effective modernization approach, our rehosting service migrates your existing applications to cloud infrastructure (AWS, Azure, GCP) with minimal or no code changes. This reduces operating costs, eliminates hardware dependencies, and sets the stage for further modernization—without disrupting ongoing operations.
Application reengineering & rebuilding
When legacy systems are too outdated to deliver modern capabilities, we help you rebuild them from the ground up using cloud-native technologies, modern frameworks (like .NET Core, Spring Boot, or Node.js), and modular, future-ready architectures with our application modernization services. The result? Better performance, scalability, and a longer lifecycle with less technical debt.
Mainframe application modernization
Our application modernization services help transform your legacy mainframe applications, improving their functionality, efficiency and integration with modern technologies. This allows for streamlined operations, improved data management and enhanced user experiences.
Application replatforming
We help you move legacy applications to a modern runtime environment—optimizing databases, updating middleware, or transitioning to managed cloud services. Our replatforming services retain your core functionality while boosting performance, resilience, and compatibility with newer tools and frameworks.
Application refactoring & re-architecting
For enterprises seeking long-term agility, we deconstruct monolithic architectures into loosely coupled microservices, implement API-first strategies, and embed DevOps pipelines. Our refactoring services enable faster deployments, improves maintainability, and unlocks the ability to scale components independently based on demand.
Application containerization
We leverage cutting-edge containerization technologies to boost the portability, scalability and manageability of your applications, promoting efficiency and flexibility across your IT infrastructure.
Data migration services
We ensure a secure, seamless migration of your data during the modernization process, preserving its integrity and accessibility. Our data migration services prioritize data security, accuracy and minimal downtime.
SaaS modernization
We transform your legacy application into a multi-tenant, subscription-based SaaS product that is secure, highly available, and cloud-optimized. This includes implementing tenant isolation, role-based access, usage metering, and integrations with payment gateways—helping you unlock recurring revenue models and a broader customer base.
Cloud application modernization
Our team enables seamless cloud-native transformation—leveraging containers (Docker, Kubernetes), serverless computing, and CI/CD to boost delivery speed, fault tolerance, and operational efficiency. Whether it’s lift-and-shift, re-architecting, or hybrid cloud adoption, we tailor cloud modernization strategies to your business goals.
Middleware & database modernization
We help you modernize outdated middleware platforms and legacy databases—migrating to scalable, cloud-compatible alternatives like PostgreSQL, MongoDB, or Amazon RDS. This ensures better data accessibility, faster query performance, tighter integrations, and reduced maintenance overhead.
UI/UX modernization
Modern customers expect sleek, intuitive interfaces. We help you redesign your legacy user interfaces using responsive frameworks (React, Angular, Vue) with a focus on accessibility, usability, and brand alignment. Our team of UI/UX specialists conduct user journey mapping and A/B testing to create experiences that delight and convert.
