Engineering

Backend focused on .NET, microservices and AWS cloud, always owning systems in production. What I use, by area:

Backend · C# and .NET at the core

I build APIs and services in C# and .NET, both REST and real-time, and use Go when it makes sense.

Architecture · Systems that handle change

I keep the domain apart from databases and frameworks, split it into services and integrate through events.

Cloud · AWS every day

I use AWS managed services and describe infrastructure as code.

Data · Relational and NoSQL

I work with relational and NoSQL databases, caching and query optimization.

Quality · Tests as part of the process

Automated tests are part of the process, not the last step. I review code and keep an eye on metrics, logs and tracing.

Delivery · From commit to production

I standardize environments with containers and automate build, tests and deploy.

AI · AI-assisted engineering

I use AI agents in development, guided by specs, with skills and MCP servers configured in the harness.
