Dependency Injection in Python with Protocol and dependency-injector

I’m a backend-focused web engineer with a strong interest in system design, domain modeling, and data-driven architecture. I primarily work with Scala (ZIO, functional patterns) and TypeScript, and I enjoy building reliable APIs, CQRS-based systems, and well-structured monorepos. Beyond coding, I’m interested in finance, optimization, and using technology (including AI) to improve decision-making and productivity. I write about software architecture, engineering workflows, and practical problem-solving.
