About Me

I'm a Computer Science and Engineering graduate focused on Python backend development, AI/ML, and Generative AI.

I enjoy building practical applications that combine language models, information retrieval, APIs, and secure software engineering.

  • Building Python applications and REST APIs with FastAPI.
  • Exploring LLMs, embeddings, semantic search, and RAG.
  • Working with machine learning workflows and model evaluation.
  • Applying application security and secure code review practices.

Career goal: Build reliable, useful AI applications with strong software engineering foundations.
