I've led technical systems and in-house application development at The Assam Tribune, supporting a 90-year-old English newspaper and its digital media operations.

Previously at PragNews, I oversaw IT infrastructure for the digital media team while developing web applications, web portals, e-paper systems, and digital media profiles. At KBG Software, I managed a team of 20 programmers and developed ERP, CMS, and SaaS products using PHP, MySQL, Python, React, and React Native.

My recent data engineering work includes a PySpark fraud analytics pipeline that achieved 91% ROC-AUC and processed features four times faster than single-node frameworks. I've also built real-time Kafka and Spark clickstream pipelines, large-scale ETL systems, continuous retraining workflows with Airflow, and distributed inference pipelines that reduced cloud costs by 68%.

I work across AWS, GCP, Databricks, Snowflake, MLOps, full-stack development, cloud infrastructure, and agile delivery, with a focus on turning data and technology into reliable production systems.
