Full CV
I am a full-stack web developer with 16 years of experience. I can supervise the technical design as well as the implementation of an entire web application. I would like to help your company reach its goals using my skills as a full-stack consultant. My strengths include Java/Kotlin Spring Boot (backend), Terraform, and Ansible (DevOps), but I also know my way around frontend (Vue.js, React). In the past, I have primarily worked on short-term projects; currently, I am looking for long-term collaborations.
