Services - Legacy Code Porting & C#/.net Development
I'm an entreprenuer and software developer, SaaS founder, and computer book author with over 30 years of experience building and modernizing software systems. I specialize in porting and modernizing legacy codebases to robust, maintainable, and scalable modern platforms, with a focus on .NET and contemporary cloud-native architectures. As founder of Bluedog Cyber Security, I also bring a deep understanding of secure coding practices, ensuring that modernization projects are designed and built with security baked in from the ground up.
What I offer
Legacy assessment & strategy:
System inventory, dependencies mapping, and risk assessment
Technical debt measurement and modernization roadmap
Stakeholder alignment, secure requirements, and technical documentation.
Code porting & modernization:
Porting VB/VBA/ASP code to modern C#/.NET patterns
Refactoring to clean architecture, modular components, and testable code
Migration of business rules, workflows, and integrations to modern services
Secure coding review and threat modeling integrated into the porting process.
Modern architecture design:
Cloud-native architecture on .NET, microservices, or monolith-to-service transitions
API-first design, event-driven patterns, and scalable data access
Security hardening, CI/CD pipelines, automated testing, and security audits.
Data strategy & integration:
Migrating data stores to modern databases and data access layers
Seamless integration with cloud services, queues, and external APIs
Data migration planning, rollback strategies, and validation.
Delivery & enablement:
Hands-on hands-off blends: I can work as an expert consultant or as an embedded teammate
Technical leadership, code reviews, and mentoring
Comprehensive documentation and knowledge transfer to your team
Security-focused enablement: training and documentation to sustain secure practices.
Why work with me
Deep legacy understanding: 30+ years in the industry means I’ve seen and repaired countless
anti-patterns, architectural drift, and fragile integrations.
I don’t just rewrite code; I capture the intent, constraints, and business rules that drive your system.
Proven modernization pathway: I guide you from assessment through to deployment, with a clear,
low-risk plan that minimizes downtime and preserves business value.
Expertise across stacks: From VB, VBA, and classic ASP to modern .NET, C#, and cloud services, I translate
old concepts into current best practices without losing the original functionality.
Security by design: As founder of Bluedog Cyber Security, I embed secure coding practices, threat modeling,
and secure deployment patterns into every project, reducing risk and building resilience.
SaaS and entrepreneurship perspective: Having founded and run software-as-a-service businesses,
I design systems that scale, are secure, and align with commercial goals.
Author’s insight: My published books with O’Reilly give me a unique ability to document, teach, and
communicate complex modernization tasks clearly for technical and non-technical stakeholders.
