01 / What I bring
A builder’s mindset.
An architect’s perspective.
From the system you already depend on to the product you’re ready to build.
Build the product.
Bring together APIs, interfaces, databases, payments, and AI workflows into a coherent SaaS product that can evolve beyond its first release.
SAAS · AI INTEGRATION · FULL STACK
Connect the moving parts.
Make software work across desktop apps, mobile devices, cameras, robots, and external services. The interesting work often lives between systems.

02 / Selected experience
Beyond the happy path.
A selection of client work and independent product development. Illustrations represent the systems, not product screenshots.
Client work / Technical leadership
From legacy to Blazor.
Led a five-developer team migrating a legacy system to Blazor for a US client, combining hands-on development with technical direction.
Inside the work
Bringing existing business behavior into a modern application means understanding what is already there, coordinating implementation, and making architecture decisions the team can carry forward.
Systems integration / Sports & automation
Software meets the physical world.
Built scoring and display applications and worked on robot control and camera capture workflows, connecting WPF interfaces, network messages, and device integrations.
Inside the work
The ecosystem spans an umpire scoring interface, a large-screen display, host controls, and camera capture triggers. Integrations include APIs and Google Sheets logging.
Independent product / AI Book Studio
From an idea to a book plan.
Developed an AI-assisted book creation product with a guided flow for idea analysis, direction selection, strategy, and titles, using a .NET backend and React frontend.
Inside the work
A layered backend separates domain logic, application workflows, and infrastructure. The frontend turns a multi-step creative process into a structured review-and-edit experience.
Client work / Production maintenance
Keep critical systems moving.
Worked on existing event and tournament applications, tracing database and application issues and improving bracket displays, forms, and payment summaries.
Inside the work
Hands-on troubleshooting across application logic, stored procedures, ODBC configuration, and hosting. A practical understanding of older systems helps make targeted changes with care.
03 / The person behind the code
I like problems
that need more
than another library.
My strongest work starts with understanding the system: what the business needs, where the friction is, and what will actually make it better.
I’m a senior C# developer with a master’s degree in computer science and 13+ years of production experience. My work spans enterprise applications, desktop software, web products, and hardware integrations.
I’ve spent three years working on-site in France and four years working remotely with French companies, alongside experience with US clients. I’m comfortable getting into the code, leading a team, and discussing trade-offs directly.
01 / UNDERSTANDGet the context before choosing the solution.
02 / OWNFollow the problem across system boundaries.
03 / SIMPLIFYKeep the architecture useful and maintainable.
04 / DELIVERTurn decisions into working software.
