I am a senior Microsoft backend and cloud developer, U.S. citizen, and native English speaker living in the Netherlands and working as a freelancer for enterprise clients across the U.S. and Europe. My working day overlaps with U.S. east coast time from 7am to 2pm, with flexibility to adjust when needed. I specialize in Azure-based platforms, cloud migrations, backend API development, and DevOps automation, working hands-on daily in C#, .NET, and SQL. I am an expert with C#/.NET, [ASP.NET](http://asp.net/) (24+ years), SQL Server (28+ years), Azure (15+ years), and Azure DevOps (6+ years), and I frequently step into a tech lead role to help teams improve delivery, architecture, and platform stability, without stepping away from the code. With 30+ years of experience, including 25+ years in consulting and 20+ years leading development teams, I have delivered enterprise systems for the U.S. Air Force, AT&T, Kaiser Permanente, Dell, Rabobank, 3M, and more, in environments with high expectations around reliability, security, and pace of change. Recent work highlights include: * Migrating a complex ASP.NET/SQL Server application to Azure in 5 weeks, with all infrastructure-as-code built from scratch (CCi Global Technologies) * Cutting production deployment times from 2 days to 20 minutes by redesigning CI/CD pipelines (OpenPath) * Stabilizing a high-volume SaaS platform with Datadog observability and Polly resilience engineering after months of production failures (ListKit) Beyond technical work, I bring real leadership and business experience. I co-founded Volare Software 17 years ago and continue to lead it today, generating $8.5M in consulting revenue across 33 clients who have retained me multiple years and across multiple projects to stabilize, extend, and modernize their core platforms. I am currently seeking a 6-12+ month assignment as a senior developer or tech lead who codes most of the time. I would be happy to discuss how I could contribute to your team. Please get in touch!

AI Systems Architect, GTME, CSA, SRE, and Fractional CTO helping organizations leverage custom AI, autonomous agents, and cloud infrastructure to build products faster, automate operations, and scale efficiently. Expert in custom AI model development, fine-tuning, RAG implementations, multi-agent systems, AI-powered workflow automation, LLM integration, cloud architecture, cybersecurity, and high-availability SaaS operations. With decades of hands-on engineering experience and deep expertise in modern AI tooling, I bridge the gap between traditional software engineering and next-generation AI systems. I build production-ready AI solutions that deliver measurable business outcomes—not demos, prototypes, or hype. From custom AI platforms and autonomous agent ecosystems to cloud-native SaaS infrastructure and mission-critical production environments, I help organizations deploy secure, scalable systems that create immediate operational leverage. Extensive NDA obligations limit what I can publicly share, but my experience spans startups, growth-stage companies, enterprise organizations, and large-scale SaaS platforms operating under demanding uptime, privacy, and security requirements.

Experience with hundreds of other languages, platforms, and technologies, including Kubernetes, Argo, Git, HTML/CSS, SCSS, Vue.js, AngularJS, Oracle Database, and many more.

Professional Software Developer since 2005 (and been excited to build software since 1991). I specialize in web applications and backend services, although I also dabbled in frontend development, data science and signal processing. After working for small companies, I have learned to produce quick and efficient prototypes from not-exactly-clear requirements. After working for big companies (Google etc), I now have a passion for developing clear, reliable and highly maintanable solutions. I also excel at debugging and solving extremely complicated issues that arise in big production systems. I'm great with Python, Java, JavaScript and Go - and I'm also a quick learner, constantly adding new technologies to my tool belt.
