Software Engineer
Software Developer
Professional Master's in Software Architecture
Five-year work-study program in software engineering and application architecture.
Frontend
Primarily Next.js and TypeScript, aiming for interfaces that are simple to maintain, performant, and accessible before adding complexity.
Backend
Designing robust APIs in .NET, with architecture that stays clear and scalable — monolithic or microservices depending on what the project actually needs.
Databases
Mostly MongoDB and PostgreSQL, with growing attention to data modelling and query optimization.
DevOps
Docker and CI/CD are part of daily work, both in development and in production. Kubernetes when the project scale justifies it.
