🚀 About Me

I'm a Data Engineer with over 3 years of experience in building and optimizing cloud-native, scalable data pipelines using modern data stacks. My journey has focused on crafting high-performance ETL/ELT workflows, automating cloud infrastructure, and enabling real-time data access that supports analytics and ML use cases.

I have hands-on experience designing robust systems using:

• AWS Services like Glue, Lambda, Step Functions, DMS, Kinesis, S3, Redshift, CloudWatch
• Big Data technologies like Apache Kafka, PySpark, Delta Lake, Airflow, and Ab Initio
• Languages & Frameworks: Python, SQL, Flask, Shell, LangChain, PyTorch

I am also passionate about AI/ML and LLMs, and actively explore ways to integrate them into data engineering workflows.
