How I work

Engineering focus

The strengths I bring to a software team are grounded in practical implementation, security awareness, and a willingness to keep learning.

Backend foundations

I work across C#, Python, PHP, and JavaScript ecosystems, using REST, MVC, DTOs, and clear separation of responsibilities as practical design tools.

My goal is straightforward: code that another engineer can understand, extend, and debug without unnecessary friction.

Security and reliability

I think about performance through concrete mechanisms: caching, rate limiting, efficient data access, and predictable request flows.

In AI-backed services, I also pay attention to prompt-injection risk, server-side secrets, and the boundaries between user input and provider access.

Data and AI curiosity

I use data analysis and machine learning to ask better questions, test assumptions, and communicate patterns clearly.

SteamScope combines pandas, scikit-learn, CatBoost, XGBoost, and Jupyter with an experiment-driven approach to classification.

Full-picture thinking

Computer engineering training helps me reason beyond a single endpoint: from data models and service layers to browser workflows and real-time communication.

I am comfortable learning through Linux environments, Docker-based workflows, debugging, and the practical constraints around delivery.

Clear collaboration

My current role and previous internship taught me to make progress visible, ask precise questions, and keep technical decisions understandable to the people around me.

I work comfortably in English and value feedback loops that improve both the product and the way the team builds it.

Open to opportunities

Let's build something reliable

I am open to full-stack and backend software engineering roles where I can contribute to APIs, real-time workflows, data systems, and AI-enabled products.
