Full-Stack Software Developer & Data Analyst.
I build high-performance web applications, scalable distributed backends, and data intelligence systems with modern stacks including MERN, Next.js, TypeScript, Python, PostgreSQL, SQL, and Google BigQuery.
NOT JUST CODE.
I LIKE SOLVING THE PROBLEM BEHIND IT.
I’m a full-stack software developer and data analyst focused on building practical, high-performance web applications and data-driven systems. My work bridges the gap between scalable full-stack architectures (MERN, Next.js, TypeScript) and high-volume data warehousing (SQL, Google BigQuery).

Bridging Application Logic & Data Intelligence.
My passion is building software that solves genuine operational and business bottlenecks. With deep expertise across full-stack web engineering, distributed microservices, and large-scale data warehousing, I architect solutions that are both technically sound and user-centric.
As a Data Analyst at Owy Technosys, I contribute to the core analytics and reporting infrastructure for Petpooja POS — authoring optimized SQL and Google BigQuery data pipelines that power business intelligence and revenue metrics for thousands of enterprise restaurant locations.
On the software engineering side, I build production platforms with modern stacks like Next.js 15, TypeScript, MERN (MongoDB, Express, React, Node.js), Docker sandboxing, and real-time WebSockets — including AI workflow engines like NexusAI and collaborative workspaces like PulseSync.
