About Me

Building scalable solutions with modern technology

I am a Software Engineer at Polestar Analytics, where I am developing 1Platform, an ETL automation tool designed for building efficient ingestion and transformation pipelines. I leverage cutting-edge technologies and modern engineering practices to enhance the performance, reliability, and scalability of the system, delivering tangible value to B2B clients. Before joining Polestar Analytics, I worked as a Software Developer at the Ministry of Education’s Innovation Cell (MIC–AICTE), where I contributed to the KAPILA and SIC portals. I successfully revamped the KAPILA Portal, upgrading its backend from PHP 7.4.1 to PHP 8.1.25, significantly improving performance and maintainability.
