Additional information

I build end-to-end SaaS products - from idea and architecture to production and real customers.

I designed, developed, and launched Restiq, a multi-tenant restaurant SaaS platform with a virtual waiter, self-service administration, custom domains, and production deployments. I work across the full stack, from backend architecture and database design to responsive frontend development, testing, Dockerization, and cloud deployment.

My primary technical focus is Java and Spring Boot, with hands-on experience in REST APIs, Spring Data JPA, Hibernate, PostgreSQL, and Docker. I also build frontend interfaces using Thymeleaf, HTML, CSS, and vanilla JavaScript, and have practical experience with Nginx, SSL/TLS, Oracle Cloud, and production infrastructure.

I enjoy working on products where engineering decisions are closely connected to real user needs. I am comfortable working independently and in agile, cross-functional teams, and I am particularly interested in product-oriented Full-stack, Java, and SaaS engineering roles.

I actively use AI-assisted and agentic development tools such as Codex to accelerate implementation, testing, debugging, and product development.

Tech stack: Java 17, Spring Boot, Spring Data JPA, Hibernate, REST APIs, PostgreSQL, MySQL, Thymeleaf, JavaScript, HTML/CSS, Docker, Docker Compose, Nginx, Oracle Cloud, JUnit, Mockito, Git/GitHub
