Jonas M.

👋 Hi! I'm Jonas. I’m a Backend Developer from Eastern Europe with 10+ years of experience in web and software development, currently focused on building scalable backend systems using Java 17, Spring Boot, and microservices. I specialize in building robust REST APIs and cloud-native deployments using Docker, Kubernetes, and CI/CD workflows. ✉️ Feel free to reach out — I’m always happy to discuss your goals and share advice before we begin working together. 🔧 CORE SKILLS: • Spring Boot, Spring Security, Spring Cloud • REST APIs, Hibernate, JPA • Microservices and system design • SQL/NoSQL databases • Docker, Kubernetes, CI/CD workflows, Terraform, Bicep (Azure) • Custom ETL systems for data synchronization and transformation • Secure API integrations (OAuth2) • Unit, integration, and contract testing (JUnit, Mockito, PowerMock) • Occasional frontend support (ReactJS) • Supporting and improving legacy systems when needed (e.g. based on Java EE) ☁️ I have hands-on experience with cloud platforms like Microsoft Azure and Azure DevOps, and I’m familiar with modern development workflows (CI/CD, Docker, Kubernetes, etc.). I’ve also worked with Infrastructure as Code tools like Terraform and Bicep. I follow industry best practices and write code that’s clear, reliable, and easy to maintain. 🗣️ Fluent in English and available for part-time work (5–20h/week). I work independently, communicate clearly, and deliver production-grade code.
