About

Who I am as a professional

A fast-learning engineer who can move between SQL queries, dashboards, code and cloud configuration – with a strong emphasis on clarity, documentation and reliability.

I started with core Computer Science fundamentals and gradually moved into building real systems: data projects, dashboards, web apps and domain-based email infrastructure. I like understanding the full flow – from how data is stored and processed to how it is visualized and finally delivered to users.

  • Clear communication: I translate business or team requirements into technical tasks, then explain results back in simple, outcome-focused language.
  • Process-driven: Familiar with SDLC/STLC, I design test cases, log bugs, and iterate until features are stable.
  • Hands-on learner: I prefer implementing real setups – like DNS, SPF/DKIM/DMARC and cloud hosting – to understand how systems behave in production.

How I work

I take ownership of my tasks, ask for feedback at the right time and keep my work documented so that others can easily understand and extend it.

Current focus

Strengthening SQL, DAX and Power BI while deepening my understanding of deployment, DNS and email systems used in real projects.

Beyond code

I enjoy content writing and email marketing, which helps me present technical work in a clear and engaging way.
