.NET backend architecture, the microservice-or-monolith decision, and a domain model that survives growth.
Software architecture is the design that decides how a system is split into parts, how those parts talk to each other, and which choices cannot be reversed later. GG Tech's Software Architecture & System Design service produces that design for .NET backends: the domain model, the service boundaries, the microservice-or-monolith decision, and the reasoning behind each technology choice — written down so your own team can carry the system without us.
| Typical team | 1 architect + 1 senior developer |
|---|---|
| Calendar band | 3–8 weeks |
| Phase split | 35% current-state analysis · 35% domain model & decisions · 20% prototype & validation · 10% handover |
What grows the budget
Signs of underbudgeting
These are GG Tech Teknoloji planning bands, not a quote — we do not publish prices. Every project is different, so the bands are deliberately wide; they assume a senior, focused team and typical scope, and your project is estimated individually.
Current-state analysis
We read the running code and the database rather than the documentation: what calls what, where each record actually lives, and which behavior nobody wrote down.
Domain model and boundaries
Entities, ownership, and transaction boundaries. This is where a service boundary is either drawn correctly or paid for later.
Architecture decisions on the record
Monolith or microservices, synchronous calls or queues, which store for which data — each decision written with the alternatives it beat and the cost it carries.
Incremental rollout
The design ships in slices that run in production. An architecture nobody has executed is a document, not a system.
What we deliver
.NET backend architecture, the microservice-or-monolith decision, and a domain model that survives growth.
Our team combines domain expertise, modern engineering, and research-driven design to build solutions that scale. We work in focused sprints with clear milestones and measurable outcomes.
