Defining modernization patterns across a distributed .NET estate

Application architecture and platform modernization across mobile, web, internal platforms, external applications, .NET APIs, monolith decomposition, Azure, and CI/CD.

  • .NET and cloud modernization
  • Monolith decomposition
  • Strangler-pattern modernization

Context

Engagement under TEKsystems supporting modernization across a distributed .NET estate for a logistics organization.

Challenge

Modernize a multi-platform estate while improving boundaries, delivery systems, and implementation patterns without stopping product delivery.

Scope

  • approximately 20 repositories
  • approximately 20 components
  • approximately 200 endpoints
  • approximately 340 services
  • two teams

My role

Application architecture and platform modernization across client platforms and services.

Approach

  • iOS, Android, web, and internal platform architecture support.
  • External customer-facing application work.
  • CI/CD architecture improvements.
  • Legacy .NET API modernization.
  • Greenfield application delivery.
  • Monolithic API decomposition.
  • Lift-and-shift migrations.
  • Strangler-pattern modernization.
  • Infrastructure and CI/CD improvements.
  • Application-boundary definition.
  • Implementation patterns.
  • AI/ML experimentation for data analysis and chatbots.

Outcome

  • Defined modernization patterns across a distributed estate.
  • Improved application boundaries and delivery practices.
  • Supported concurrent modernization and feature delivery approaches.

What I learned

  • Strangler patterns enable incremental modernization without a big-bang rewrite.
  • Boundary definition is a prerequisite for safe decomposition.

Open questions for refinement

  • Which modernization outcomes are strongest to highlight publicly vs. interviews only?
