.NET Software Architect & Technical Consultant (Independent)
Danilo Ruziska Tech
Helping CTOs and Engineering Leads eliminate technical debt, rescue delayed projects, and build scalable .NET architectures.
With 20 years of hands-on experience in the .NET ecosystem, I provide high-level technical support to companies that need senior expertise without the cost of a full-time hire. My background includes working as a Visma .NET Ninja, a Microsoft Student Partner, a Consultant working on behalf of Microsoft, and an intern at the Microsoft Innovation Center.
How I add value to your project:
- Architecture & Code Audits: In-depth analysis of C#, ASP.NET, and SQL Server/Oracle/NoSQL structures to identify critical risks and scalability bottlenecks.
- Technical Debt Resolution: Strategic refactoring and troubleshooting of complex legacy systems to restore development speed.
- Modernization Roadmap: Leading the transition from legacy frameworks to modern .NET Core and React-based architectures.
- Technical Leadership & Mentoring: Applying high-standard engineering practices such as SOLID, TDD, and Extreme Programming while fostering an agile culture as a Certified Scrum Master since 2011.
As an individual with Autism Support Level 1 (Asperger Syndrome), I have a strong ability to focus deeply and recognize patterns. I use this strength to spot logical inconsistencies and architectural flaws that often go unnoticed, ensuring precise code quality and system reliability.

Summary
38 years old, autistic support level 1 (also called Asperger Syndrome)
Passionate about technology since I was 5 years old, when my father brought my first computer with Windows 3.1 home, I turned my hobby into a profession, and since 2005, I have worked as a software developer.
My specialty is the .NET platform. I create applications for a wide range of market segments, including web and Windows applications, APIs, and frameworks. I mainly use C#, SQL Server, Oracle, and some NoSQL databases (mainly MongoDB), as well as frameworks and frontend languages such as JavaScript, CSS, HTML, React, and ASP.NET MVC.
A programmer by profession and a software engineer in my daily work, I am passionate about studying and constantly learning how to improve software quality. I make this my daily task: writing software in the best possible way, with a focus on ease of maintenance and, especially, testing. Whenever the project I'm working on allows it, I try to apply Extreme Programming, TDD, and SOLID practices. I also have knowledge and experience in BDD, Azure, TFS, and Git.
I also have a passion for processes, especially agile methods. I have been a Certified Scrum Master with the Scrum Alliance since 2011 and have worked both as a Scrum Master and as part of a development team.
My goal is to work on challenging projects where I can apply the experience I have gained over the years, always in the best way possible.
