Application Modernization & Integration

Modernize legacy applications, frameworks, databases, and infrastructure without discarding the business logic that already works.

ModernizationEnterprise IntegrationCloud Transformation

Move critical systems forward

Capability aligned to the work.

We assess legacy estates, isolate risk, and modernize applications in controlled stages across Microsoft, Java, web, mobile, data, and cloud ecosystems. Integration work spans APIs, events, enterprise applications, identity, data, and partner platforms, with compatibility, security, and operational continuity treated as first-class requirements.

What this service is for

Where application modernization & integration creates practical value.

The service can be delivered as a focused intervention or as part of a broader transformation program. These are common starting points, not the limits of the engagement.

01

Legacy framework modernization

Move .NET Framework, Java EE, older JavaScript frameworks, PHP, Python, and other aging estates to supported architectures.

02

Monolith decomposition

Separate tightly coupled domains and deployment units in controlled stages without losing proven business behavior.

03

Cloud and database migration

Modernize runtime, data, identity, deployment, and observability while maintaining reconciliation and rollback controls.

04

Enterprise and partner integration

Connect ERP, CRM, Microsoft 365, identity, payments, data platforms, APIs, queues, and external business networks.

Delivery context

Built around the operating environment, not a generic delivery template.

This capability is shaped for Financial Services, Insurance, Manufacturing, Government, Healthcare and the teams responsible for Information Technology, Application Development, Operations, Data Management. The engagement connects the right engineering disciplines, controls, and technology choices to the target business outcome.

Industries

Domain-aware delivery

Architecture, workflow design, controls, and delivery priorities are adapted to the regulatory, operational, and customer realities of these sectors.

Financial Services 路 Insurance 路 Manufacturing 路 Government 路 Healthcare

Teams

Aligned with accountable owners

We work with the leaders and practitioners who own the system, its data, its operational outcome, and its continued performance after launch.

Information Technology 路 Application Development 路 Operations 路 Data Management

Solution fit

Connected across capabilities

The work can stand alone or connect with adjacent Levmetrics capabilities, allowing strategy, implementation, integration, and operation to move as one program.

Technology ecosystem

Technology selected for fit, continuity, and long-term ownership.

We work across established enterprise platforms and modern engineering ecosystems. The final stack follows the customer environment, delivery constraints, security requirements, and target architecture rather than a fixed vendor preference.

AI-first delivery

AI-augmented engineering with accountable human control.

We apply AI where it improves the speed, depth, or consistency of application modernization & integration. Agentic AI is used for bounded, traceable workflows; experienced people remain responsible for architecture, quality, security, and production outcomes.

AI-assisted estate discovery

Analyze source code, dependencies, interfaces, schemas, and documentation to accelerate system understanding and migration planning.

AI-augmented code transformation

Support refactoring, test generation, documentation, and compatibility analysis under senior engineering review.

Agentic migration assurance

Automate repeatable evidence collection, parity checks, defect triage, and migration reporting across staged releases.

Capabilities

What we deliver

  • Architecture and technical-debt assessment
  • .NET Framework, ASP.NET, Web Forms, MVC, WCF, and Windows-service modernization to current .NET and ASP.NET Core
  • Legacy Java, Java EE, and J2EE modernization to current Java, Spring, and Spring Boot
  • AngularJS, jQuery, and legacy React, Angular, and Vue application modernization
  • Node.js, Python, PHP, and other backend runtime and framework upgrades
  • Legacy native and hybrid mobile application modernization
  • Monolith decomposition, modularization, and service-based architecture migration
  • REST, GraphQL, gRPC, messaging, and event-driven integration
  • SQL Server, Oracle, PostgreSQL, MySQL, and legacy database modernization
  • Data migration, reconciliation, archival, and retention planning
  • On-premises and hosted application migration to Azure, AWS, and Google Cloud
  • Identity, access, SSO, and authorization modernization
  • Microsoft 365, Microsoft Graph, ERP, CRM, and partner-system connectivity
  • Containerization, CI/CD, infrastructure as code, and observability enablement
  • Accessibility, responsive-interface, and design-system modernization
  • Regression automation, performance benchmarking, security validation, and controlled cutover

Outcomes

Why it matters

  • Reduce operational risk in aging systems
  • Unlock data and workflows for new products
  • Move to supported runtimes, frameworks, and infrastructure
  • Modernize incrementally without a disruptive rewrite
  • Preserve business rules, integrations, and data integrity throughout migration

Approach

How it works

  1. 01Inventory applications, runtimes, dependencies, integrations, data, and business criticality
  2. 02Define target architecture, migration stages, compatibility contracts, and rollback controls
  3. 03Modernize code, interfaces, data, infrastructure, security, and delivery pipelines
  4. 04Verify functional parity, performance, resilience, security, and operational readiness
  5. 05Cut over in controlled stages, transfer knowledge, and retire superseded components

The team behind the work

Quality resources, governed delivery, and production accountability.

The application modernization & integration engagement is staffed around the required technology, domain, risk, and operating model. We combine role-specific screening, senior oversight, secure delivery practices, and measurable quality gates rather than treating staffing as a volume exercise.

Qualified, project-fit talent

Delivery teams are selected for the actual domain and stack. CCAT-verified talent is assessed for problem solving and learning agility before joining project work.

Senior engineering and quality oversight

Architecture, implementation, test strategy, release readiness, and operational handover are reviewed by experienced engineering and quality leaders.

Security expertise where it matters

Security-sensitive work can draw on KLCP-certified expertise, secure engineering practices, least-privilege access, and evidence-based delivery controls.

Cloud and platform breadth

We work across AWS, Microsoft Azure, Google Cloud, containers, serverless, Kubernetes, infrastructure as code, CI/CD, observability, and hybrid estates.

Ways to engage

Start with the scope that matches the decision in front of you.

Engagements can begin with a short assessment, a defined implementation, or ongoing product and platform ownership. The commercial and delivery model follows the outcome, risk, and level of continuity required.

01

Assessment and roadmap

A focused engagement to establish current state, business priorities, risks, target architecture, delivery stages, measures, and investment choices.

02

Project delivery

An accountable team delivers a defined outcome through discovery, architecture, implementation, quality engineering, deployment, and handover.

03

Dedicated engineering team

A stable, cross-functional team works against an agreed roadmap with transparent cadence, governance, technical ownership, and capacity.

04

Managed evolution and support

Continuing ownership for reliability, releases, enhancement, security, modernization, observability, and operating-cost improvement.

Start with the outcome

Bring us the operational constraint.We will shape the delivery around it.

Share the current system, constraint, and target outcome. We will map a practical path forward.
