Software engineer evolving into a data scientist, combining product engineering with machine learning and Generative AI.

I am a software engineer with experience building Angular applications, Java and Node.js services, RESTful APIs, and database-backed business workflows. I am currently pursuing an MSc in Data Science in London, strengthening my ability to turn complex data into reliable models, clear insights, and useful intelligent products.

My data science and GenAI studies span Python, R, statistics, exploratory analysis, machine learning, deep learning, NLP, computer vision, transformers, RAG, vector databases, LangChain, and Streamlit. This blend allows me to approach problems across the full lifecycle—from data and modelling to APIs, interfaces, and production-minded delivery.
