Cloud Architecture
Practical Azure and AWS architectures for real production systems.
DevOps & CI/CD
Deployment pipelines, infrastructure automation, observability, and engineering workflows.
.NET Engineering
Modern .NET architecture, migrations, performance, APIs, and maintainable application design.
Data Engineering
Data pipelines, warehouses, analytics platforms, Databricks, Snowflake, and modern data architecture.
Software Architecture
Architecture patterns and engineering decisions for systems that need to survive real-world complexity.

Legacy application modernization
Your legacy application may not need a rewrite.
Plenty of businesses still run on systems built in Visual FoxPro, VB6, Classic ASP, or early ASP.NET. They are often slow to change and hard to hire for, but they also contain years of working business logic. Throwing that away is the riskiest option on the table.
A better approach usually starts with understanding what the system actually does, then modernizing it in increments: stabilize, extract, migrate, and retire, with production running the whole time.
Systems we see most often
- Visual FoxPro
- VB6
- Classic ASP
- ASP.NET Web Forms
- .NET Framework 4.x
- SQL Server 2008–2016
- Access front ends
- Tightly coupled monoliths
Assessment
Inventory code, data, integrations, and the business rules nobody documented.
Incremental modernization
Replace the system in slices that can each be deployed and verified.
API extraction
Put stable interfaces in front of legacy logic so new code can depend on it.
Database modernization
Normalize, migrate, and version schemas without stopping the business.
UI replacement
Move users to a web front end while the back end keeps working.
.NET migration
Port or rebuild services on modern .NET with tests around existing behavior.
Cloud migration
Rehost, replatform, or refactor into Azure or AWS based on actual constraints.
Phased rewrites
When a rewrite is justified, sequence it so value ships before the end.
Engineering philosophy
Practical engineering, not architecture astronautics.
CloudCrafterLabs focuses on approaches that work under real constraints: existing systems, production users, limited budgets, technical debt, deployment risk, and teams that still need to ship.
Preserve what works
Working business logic is an asset. Replace it only when there is a reason to.
Ship in increments
Every step should be deployable, observable, and reversible.
Decide with evidence
Measure the system before redesigning it. Write down why.
