Engineering reliable software and data-driven systems

01. About

I am a B.Tech undergraduate at IIT Guwahati whose work connects software engineering, data and machine learning, and algorithmic problem solving. This combination enables me to design dependable applications, analyse data rigorously, and approach technical problems with strong computational fundamentals.

• Software Engineering

  Full-stack applications, backend APIs, real-time communication, and relational database architecture.

• Data / ML

  Data analysis, classical machine learning, deep learning, and evidence-grounded AI applications.

• Problem Solving

  Algorithms and data structures developed through consistent competitive programming practice.
