À propos de Ramona
Having worked in start-ups (scale-ups) and small-sized companies, I have a strong understanding of business expectations and user demands, as well as a product mindset on software architecture.
Full-stack engineer with strong backend expertise in Java and Kotlin, experienced in scalable production systems, mainly in healthcare and e-commerce. I help teams ship reliable APIs, untangle complex business rules, and deliver features end-to-end with a product mindset and pragmatic, ethical use of AI tools.
I work independently and take ownership of features from the initial discussion through delivery and maintenance.

- Building Mytherion Backend, a Kotlin + Spring Boot service for a world building app; implemented PostgreSQL + Flyway schema migrations and environment-based config using Docker.

- Developing Narratopia Frontend (React + Vite + Tailwind): early UI and test setup (Cypress), planned integration with a backend API.
- Created and applied repeatable GenAI-assisted workflows for software tasks (function-level coding, implementation, refactor pass, test plan, edge cases), using reusable prompts + verification checklists with GPT/Claude, to reduce rework.

- Extended internal admin tooling (Backoffice): implemented backend changes and contributed React/TypeScript UI components to support mental-health booking operations.
- Implemented a patient intake form integration in the booking flow, coordinating data exchange across services and keeping a consistent state through multi-step booking.
