What I'm looking for

I seek roles that leverage mathematics, data science, and cybersecurity—collaborative teams focused on impactful ML, secure systems, and continuous learning.

I am a mathematician and data scientist with a strong foundation in applied mathematics, programming, and cybersecurity. I combine analytical rigor with practical programming skills to build data-driven solutions and secure systems.

My work spans data science, machine learning, database management, and cryptography, with projects including encrypted network traffic classification, post-quantum cryptography visualization, and anomaly detection in time series. I have hands-on experience with PyTorch, TensorFlow, PySpark, and multiple database technologies.

I bring classroom and instructional experience at the high-school and university level, having taught statistics, calculus, physics, and other STEM courses, and served as a teaching assistant for multiple math courses. I emphasize clear communication, responsible work habits, and continuous learning.

I am eager to contribute to teams focused on data science, AI, cybersecurity, and database systems where my mathematical background, programming skills, and security tooling experience can deliver measurable impact.
