Solution Architect | .NET | Distributed Systems | Cloud
I am a .NET architect and developer. I design business systems using DDD, modularity and clear responsibility boundaries, so they can evolve without adding unnecessary complexity.
I am currently focused on practical Generative AI workflows in software delivery: from knowledge gathering and specification to implementation, review and technical decision support.
How I think about architecture
Technology should serve business, not the other way around
I match solution complexity to the actual problem
I use advanced architectural patterns only when they bring real value
I design systems with long-term evolution and maintainability in mind
I make conscious trade-offs instead of aiming for theoretical perfection
How I work
Understanding the problem
I start by understanding the business process and context. Before proposing solutions, I make sure we are solving the right problem.Architectural decisions
I design solutions based on real constraints, requirements and scale. I adapt the approach to the problem, not the other way around.Simplifying systems
I reduce unnecessary complexity, define clear responsibilities and focus on consistency. The goal is a system that can evolve, not just be delivered.Collaboration and delivering solutions
I work closely with teams and stakeholders. I support implementation, ensure quality and help bring solutions to production.What I do
System architecture
I design backend system architectures — from modular monoliths to distributed systems. I focus on clear boundaries, consistency and long-term evolution.Working with business
I collaborate with business stakeholders and end users to understand real needs. I help translate them into technical solutions and identify opportunities for improvement..NET and Cloud
I build solutions using .NET and Azure, focusing on scalability, reliability and maintainability in production environments.Integrations and APIs
I design and develop APIs and system integrations. I ensure contract consistency, stability and the ability to evolve without frequent breaking changes.Fullstack
When needed, I deliver end-to-end solutions — from backend and APIs to user interfaces. My primary focus remains on architecture and backend.Responsibilities
- •Designing backend system architectures
- •Driving architectural decisions and system evolution
- •Translating business needs into technical solutions
- •Ensuring architectural consistency and implementation quality
- •Supporting teams through mentoring and knowledge sharing

Legacy System Transformation
Sente IT Systems
Legacy system based on database logic and Firebird, with scalability issues and increasing operational risk.Approach
- •Migration using the strangler pattern.
- •Gradual decomposition of the monolith into microservices.
- •Moving parts of the processing to real-time.
- •Introducing DDD as the foundation for domain modeling.
Impact
- •Reduced risks related to stability and scalability.
- •Enabled continued development of the system and teams.
- •More coherent architectural foundation across multiple modules.
Sales and Order Management Domain Redesign
CSHARK
System with fragmented business logic, inconsistent APIs, and growing integration needs.Approach
- •Domain-driven modularization and clarification of responsibilities.
- •API redesign focused on consistency and external integrations.
- •Separation of logic between backend, frontend, and source systems.
- •Alignment of technical decisions across teams.
Impact
- •Easier development of further processes without rewriting the whole.
- •More stable API for internal and external integrations.
- •Reduced maintenance complexity.
