Where to start
Three common situations, each with a small, scoped way to begin. Every engagement ends with written outputs you can act on, whether or not we continue together.
For a new product or major capability, before serious development starts: clear system boundaries and an implementation direction.
Not included Full implementation, UI design and infrastructure provisioning.
Ask about system designFor a team with a running system, often on .NET, that is unsure about its structure or where to take it next: what to improve, what to keep, and where to start.
Not included Executing the full migration or refactoring, which can follow as a separate engagement.
Ask about a reviewFor slow responses, recurring errors or failing background processing, investigated before committing to a major rewrite.
Not included Ongoing production support or 24/7 on-call.
Ask about an assessmentScope, duration and pricing are agreed after a first conversation, once the problem is clear.
Founder experience
A platform designed and delivered from concept to V1, and an enterprise platform modernized subsystem by subsystem.
Independently architected and delivered a plugin management and licensing platform, connecting backend services, administrative interfaces, and customer-side runtime components.
Contributed to the development and modernization of an enterprise municipal software platform containing more than ten interconnected subsystems.
From my work before founding ArtaPattern. Client names and confidential details are left out, and diagrams are conceptual.
Working together
You work directly with me, from the first conversation to the final deliverable. Scope, timeline and terms are agreed in writing before work begins.
You describe the system and the problem; I ask questions until the decision in front of you is clear.
Usually System Design, an Architecture Review or a Backend Reliability Assessment, with agreed deliverables.
Follow-on work, such as implementation support or a staged migration, is planned from the findings.
Founder
ArtaPattern is my independent practice. I have spent 12+ years building C#/.NET systems: leading a municipal platform of 10+ subsystems and its move to .NET 7, and independently architecting a MetaTrader plugin management platform from concept to V1. I stay hands-on, close to the code that runs in production.
Start a conversation
Describe the system and the problem. I'll reply by email with questions or a suggested starting engagement.
