Wymagania
Strong Java and Spring Boot expertise - clean API design, domain modeling, sound architectural trade-offs. You think in terms of service boundaries, data flow, and maintainability, not just making it work
Solid grasp of software design principles - object-oriented programming, SOLID, clean architecture, separation of concerns. You write code that the next person can read, extend, and trust. You know when a pattern helps and when its ceremony
Working proficiency in React and TypeScript - you can pick up frontend tasks, build components, and integrate with backend APIs independently
Proven experience integrating AI coding tools (Claude Code, Cursor, or equivalent) into daily development workflow - including prompt design for code generation, output validation, and actively preventing AI-generated technical debt. You can describe concrete examples of where AI accelerated your delivery and where you chose to override it
Testing as a professional discipline, not a checkbox - you write unit, integration, and API tests as part of delivery, own the test pyramid decisions, and treat untested code as unfinished code
PostgreSQL - schema design, query optimization, migrations in a production context
AWS experience - youve deployed and operated production workloads on AWS (ECS/EKS, RDS, Lambda, S3) and can make informed infrastructure decisions
Comfort working in ambiguous, greenfield settings - you define scope with stakeholders rather than waiting for pre-scoped tickets
Nice-to-Have: Infrastructure as Code (Terraform).Healthcare, diagnostics, or regulated-environment experience, Security hardening practice - threat modeling, dependency scanning, secure defaults, Observability tooling (CloudWatch, Prometheus, Grafana), CI/CD pipeline design (GitHub Actions or similar)
