Software Services

Custom Software Development

Enterprise-grade software built by the person you actually talk to. 15+ years of .NET, formerly Senior Software Engineering Lead at Valtech — now working directly with businesses of any size.

The stack

C# / .NET

ASP.NET Core, MVC, and 15+ years of enterprise .NET — from greenfield services to modernizing decade-old codebases.

RESTful APIs

APIs designed for the people who have to consume them: predictable, documented, versioned sanely.

Python

Automation, data work, integrations, and services where Python is the right-sized tool.

SQL Server & PostgreSQL

Schema design, query performance, and migrations on both engines — data layers that hold up under load.

Optimizely platform

Deep CMS & Commerce specialization — covered in detail on its own page.

AI integration

LLM features, agent tooling, and MCP servers wired into existing software — see AI Business Transformation.

Ways to engage

Project delivery

A defined build with a defined finish line — scoped, priced, delivered, documented.

Fractional principal engineer

Senior architecture and hands-on development for teams that need principal-level judgment without a principal-level hire.

Rescue & modernization

Inherited codebase, departed contractor, framework three versions behind — assessed honestly, then fixed methodically.

The common thread: you work directly with the engineer responsible for the outcome. Estimates are honest, tradeoffs are explained in plain language, and "done" includes documentation your team can pick up.

Have a build, a rescue, or a hard technical question?

Describe it in a paragraph. You'll get an engineer's answer, not a sales sequence.
