Architecture reviews and evolution
I review dependencies, component boundaries, and quality attributes to identify risks and compare alternatives before major changes.

Software architecture for systems that need to evolve.
I help teams review software architectures, modernize .NET applications, and design integrations, with business and operational needs in mind.
When a system needs to evolve, the challenge is not always choosing the right technology. It is deciding what to change, what to keep, and which risks are worth taking. Those are the questions I start with when working with a team.

Areas of expertise
How I can help your team.
Whether your team needs an architecture review, a path to modernize an existing application, or help designing an integration, I can contribute to a focused assessment or a phase of a larger project. Depending on the agreed scope, the work may include prioritized recommendations and documented decisions.
.NET application modernization
I assess existing applications and dependencies to identify practical paths for incremental modernization, taking maintenance, operations, and business needs into account.
APIs and distributed systems
I help design and review APIs, integrations, and asynchronous workflows, with attention to contracts, failure handling, resilience, and observability.
Technical decision support
I work with teams to assess patterns, organize code, and document architectural decisions, connecting technical design with implementation.
Approach
Understand the system before proposing changes.
A technical decision can solve one problem while creating another. That is why I look at the current system and project constraints before comparing possible approaches.
Understand the context
I identify goals, key dependencies, business constraints, and risks in the existing system.
Make trade-offs explicit
I compare approaches and discuss their impact on maintenance, operations, costs, and the system's ability to evolve.
Define next steps
I organize recommendations and next steps, with priorities and evaluation criteria suited to the agreed scope.
Professional background
Experience with independent projects.
Alongside my work in engineering teams, I have contributed to independent projects involving the development, maintenance, and evolution of enterprise applications. These experiences broadened my understanding of business processes and different corporate environments.
