I'm an IT professional with 14+ years in system administration, PL/SQL, and L2/L3 support (Oracle, Linux, Docker). I also have project management experience – leading teams, end‑to‑end delivery, budgets, and automation.

My technical background helps me assess risks, set timelines, and talk to developers. As a PM (2025‑2026) and in prior roles, I cut manual work via Python, managed distributed teams, and reduced cost per lead.

Key achievements: promoted to PM in 2 years, supported 20+ servers, implemented Oracle GoldenGate.

Good day,
I have extensive experience in IT, ranging from system administration and technical support to development and team/project management. I quickly adapt to new technologies and software, which is reflected in my track record — in every new company, I mastered new tools or even entirely new domains (such as marketing). I am results-driven and focused on both personal growth and the overall growth of the company. For example, in my previous role, I analyzed marketing department processes and became a Project Manager. Prior to that, I joined as a regular employee and, within two years, progressed to leading the implementation and support department.

Strengths: organization, responsibility, results-oriented mindset.

Areas for improvement: I tend to strictly follow regulations, which may not always be appreciated by some colleagues. However, in the long run, this approach helps establish structure and efficiency—especially when I am involved in creating those processes.
