DocuDune | Engineered by WholeBit Solutions

We have successfully finalized the active development and public release of DocuDune, our proprietary document-conversion platform. Engineered for maximum resilience, the system has transitioned into a mature, self-sustaining cloud ecosystem. It now operates autonomously with rock-solid stability, delivering seamless production performance with zero manual operational overhead.

My Services

Consultancy

Project analysis and risk management form the basis of my consultancy work. Together with stakeholders, I review requirements, technical constraints, and delivery risks.

From evaluating project viability to planning implementation, I help teams assess options and mitigate risks around business priorities.

Architecture

.NET systems and integrations are central to my architecture work. Design patterns and SOLID principles guide how I address business requirements and support maintenance.

Alongside the team, I define system boundaries, assess technology choices, and plan implementation with scalability and existing systems in mind.

Technical Leadership

Within small and mid-sized teams, I coordinate technical work, mentor developers, and help connect implementation decisions with business priorities.

From initial design through implementation, my work with the team covers planning, agile delivery, and development practices.

Web Development

Backend services are the focus of my web development work, particularly ASP.NET Core APIs and microservices. This includes business logic, data access, authentication, and communication between services.

From service design through implementation and maintenance, I work on system integrations, messaging, and cloud deployment. React and Angular interfaces complement these services when needed.

Desktop Development

For .NET desktop applications, I use WinForms, WPF, and MAUI with C#, XAML, and XSLT across development and maintenance.

Client requirements and the platforms in use shape my work on application behavior, performance, and interface design.

Database Design

I design and develop databases using SQL Server, MySQL, and PostgreSQL, and work on query performance, data retrieval, and application integration. This also includes NoSQL data stores such as Redis and MongoDB.

In collaboration with application teams, I translate business requirements into data models and database operations. For analytics, my work also includes unified data platforms such as Azure Databricks and reporting with Power BI.
