Application Modernization
Breathe new life into your legacy applications. We modernize outdated systems using cloud-native architectures, microservices, and modern UI frameworks — reducing technical debt, improving performance, and enabling rapid feature development while preserving your business logic.
What is Application Modernization?
Application modernization transforms legacy software into modern, cloud-native solutions using microservices architectures and contemporary UI frameworks. It reduces technical debt, improves performance, and enables rapid feature development while preserving existing business logic through containerization and API-first redesign.
Engineering Targets
Figures below are the benchmarks we design and test against on this type of build. They are targets, not a warranty — what your platform actually achieves depends on your data, scale and integration surface, and we agree the numbers that matter with you before work starts.
Why This Matters
Legacy systems rarely fail outright. They get slower to change, harder to staff and more expensive to run, until a small feature takes months. Modernisation is not a rewrite for its own sake. It is restoring the ability to change safely, done in stages so the business keeps operating throughout.
What You Get
Capabilities
Legacy Assessment and Dependency Mapping
We trace what the existing system actually does, including undocumented jobs and hidden integrations, before anyone proposes a target architecture or a rewrite.
Incremental Strangler Migration
New services take over one capability at a time behind a routing layer, so the legacy system keeps running while it is progressively replaced.
Data Migration and Reconciliation
Schema redesign, backfill and dual-write periods with reconciliation reports, so you can prove old and new systems agree before any cutover date is fixed.
Monolith to Service Decomposition
We split large codebases along business boundaries rather than technical layers, so teams can deploy independently without coordinating every release across the whole platform.
Cloud Re-Platforming
Moving workloads onto managed services, containers and infrastructure as code, replacing manual server builds with environments that can be rebuilt from a repository.
Test Harness Before Change
Characterisation tests capture current behaviour first, giving a safety net that shows whether a refactor preserved the rules buried in decades-old code.
Our Approach
How We Deliver
System Archaeology
We document current behaviour, integrations and data flows before proposing any change.
Target Architecture
An agreed end state with sequencing, so each stage delivers value alone.
Staged Migration
Capabilities move across one at a time, with rollback available at every step.
Decommission
Old components retired only once traffic, data and reporting are verified on the new platform.

Common Questions
Frequently Asked Questions
What is the difference between custom and off-the-shelf software?
Custom software is built specifically for your business processes and scales with you. Off-the-shelf is faster to deploy but requires workarounds. Masarrati builds custom solutions when your needs outgrow generic tools.
How do you handle application modernization?
Masarrati uses a phased approach: assess the current architecture, identify technical debt, create a modernization roadmap, then migrate incrementally — re-platforming, re-architecting, or rebuilding as needed.
Do you build cross-platform mobile applications?
Yes. Masarrati builds native iOS/Android apps and cross-platform apps using React Native and Flutter. The choice depends on performance requirements, budget, and target platforms.
What is your approach to application integration?
Masarrati uses APIs, webhooks, message queues, and ETL pipelines to connect disparate systems. We support REST, GraphQL, gRPC, and enterprise middleware like MuleSoft and Apache Kafka.
How do you ensure application performance at scale?
Through load testing, auto-scaling infrastructure, CDN deployment, database optimization, caching strategies, and continuous performance monitoring with tools like Datadog and New Relic.
