Work with backend technologies such as Python (Flask/FastAPI) and/or Java/Spring Boot.
Manage integrations with relational and NoSQL databases such as PostgreSQL, MySQL, and MongoDB.
Contribute to testing, debugging, code reviews, and performance optimization.
Support deployments through CI/CD pipelines, Docker, and cloud/platform environments such as Azure, AWS, GCP, Kubernetes, or OpenShift.
Collaborate effectively within Agile delivery team.

Required qualifications to be successful in this role

Strong hands-on experience in full stack development.
Proficiency in JavaScript/TypeScript, HTML5 or CSS3.
Experience with React or Angular.
Experience with REST APIs, backend services, and microservices.
Experience with Python and/or Java/Spring Boot.
Strong knowledge of SQL databases; familiarity with MongoDB or other NoSQL databases.
Experience with Git, CI/CD, and containerization tools such as Docker.
Familiarity with cloud or platform environments.

Nice to Have:

Redux, Context API, NgRx
Jest, React Testing Library, JUnit, Mockito
Spring Data JPA, Hibernate, Flyway
OAuth, JWT
Additional front-end exposure such as Vue.js or jQuery
