Have you been a full-stack analyst, solving both business tasks and system skills?

Yes, the role of a full-stack analyst involves combining skills in both business analysis and technical aspects. This means that in addition to gathering and formalizing requirements, analyzing business processes, and interacting with clients, I also engaged in systems analysis: understanding system architecture, participating in design, sometimes writing technical documentation, and interacting with developers on a technical level. This approach allows for a better understanding of the relationship between business requirements and technical implementation, which improves the quality of solutions.
