PROFILE
I have practical experience working in an IT department on a project focused on training neural
networks for computer vision tasks. I worked as a full-cycle data annotator: from dataset
preparation and technical documentation to reviewing colleagues' annotations and mentoring
new team members. I have a solid understanding of workflow organization, experience working in
a team using Agile methodologies, and closely collaborated with ML engineers and QA
specialists.
Currently, I am highly motivated to expand my knowledge in programming, aiming to deepen my
understanding of Java and related technologies, and to gain hands-on experience in software
development. I am looking to start my career as a Java developer in a team where I can grow as
an engineer, enhance my technical skills, and contribute to real-world projects.
