$about

System Architecture

The engineering mindset behind the systems.

$cat about.md

I'm a developer and data analytics enthusiast pursuing a BS-MS dual degree at IISER Kolkata, with deep interests in mathematics, quantitative finance, and AI-driven systems.

I work on analytics projects, backend systems, and automation tools with a growing interest in quantitative finance and data-driven decision making.

I approach every problem as a systems problem — identifying inputs, outputs, constraints, and optimal workflows. Whether it's building a RAG document intelligence engine or a quantitative backtesting framework, the goal is always the same: create reliable, scalable infrastructure that works.

>Passionate about solving real-world problems through technology and data-driven thinking.
