Most of my work comes down to making systems that can change without breaking. Building a multi-tenant SaaS platform properly from the start. Making a codebase that's become hard to modify modular again. Adding features to a mature system without disturbing what already works. Or putting AI into a product that already exists, without turning the rest of it into an experiment. My main backend stack is .NET and C#, with Node.js alongside it. Frontend is Angular, React or Next.js, on Azure or AWS. I've also picked up Python and Go when a client's microservices needed it, because "that's not my stack" isn't a useful answer to someone with a problem. Your requirements will change, and you shouldn't have to pay twice for that. This is why I care about SOLID, design patterns and modularity, not because they look good on architecture diagrams. On an enterprise AI product, keeping model providers behind a clear abstraction meant switching between Claude and OpenAI stayed localised instead of spreading provider-specific code through the application. On a multi-tenant insurance platform, Clean Architecture kept the domain and application layers independent of the database underneath them. If your system is past the easy CRUD stage, that's where I'm most useful. Multi-tenant architecture, complex business workflows, third-party integrations, background processing, authentication and RBAC, or an application that needs to evolve rather than be rewritten. With AI, the hard part isn't the model, it's everything around it. I've built RAG systems, document processing and structured extraction inside SaaS products that already existed. I use these tools daily in development too, which is how I know where they get dangerous. So I work in testable phases and watch authorisation, tenant isolation, data integrity and concurrency closely, because that's where code compiles perfectly and is still completely wrong. You'll also get honest answers. If an approach is unnecessarily complicated or risky, I'll tell you and explain why. Useful feedback now beats a comfortable answer followed by a production issue three weeks later. If you're building a SaaS product, adding AI to an existing one, or modernising something that's become hard to change, send me a message and tell me what you're working on.
