Message

I've built Python backend services and data pipelines for Publicis Sapient, Programming.com, Trantor, Nettechnocrats, and Onextel Media.

At Publicis Sapient, I modernized Capital Group's legacy AutoSys pipelines to Apache Airflow and Databricks. I developed ingestion, transformation, validation, and processing workflows using Python, Amazon S3, REST APIs, AWS Lambda, PostgreSQL, and Harness.

At Programming.com and Trantor, I developed REST APIs and microservices with Python, Django, Flask, and MySQL. I also automated ETL pipelines with Redshift Spectrum, AWS Lambda, Jenkins, S3, and SNS, and supported ML model integration and data preprocessing.

Earlier, I built Django applications for Ramp Rewards and Ektaseb and enhanced high-volume SMS processing for an SMPP project. I bring experience across backend development, workflow orchestration, cloud data processing, CI/CD, and production application maintenance.
