💫 About Me

🔭 Currently building a real-time ETL pipeline (Kafka · Spark · Airflow · star-schema warehouse) and AI/data-engineering backends.
👯 Open to collaborating on data pipelines, RAG systems, and Django/DRF backends.
🌱 Going deep on Apache Spark, distributed data processing, and data warehouse design.
💬 Ask me about Django REST Framework, RAG (pgvector, multilingual embeddings), Kafka, ETL, and AWS.
⚡ Fun fact: I reached production-level Django proficiency in a short time through intensive hands-on projects.
