About
I am a B.Tech Computer Science Engineering student at Lovely Professional University. My focus right now is depth over noise — problem solving, core CS fundamentals and shipping software I would be comfortable defending line by line.
I would rather understand one algorithm completely than half-remember ten. That is the standard I am holding myself to through the degree: fundamentals that hold up under questioning, and software that actually runs.

Work
Two builds I am actively working on. Status is stated plainly — nothing is called finished before it is built, and links appear only when the repositories are public.
01
AlgoVisualizer
In progress
Interactive DSA visualization tool for understanding sorting and searching algorithms through step-by-step animations.
Seeing an algorithm move is the fastest way to understand why it works.
- React
- JavaScript
- Tailwind CSS
Links published once the repository is live

02
DSA Tracker
In progress
Developer productivity and DSA progress tracker for organizing coding practice, study goals and learning progress.
Structured practice beats scattered problem solving.
- React
- JavaScript
- Tailwind CSS
- LocalStorage

Problem Solving
Where I actually am with data structures and algorithms — described qualitatively, with no invented counts, ratings or contest results.
Method
- 01C++ as the primary language — STL, complexity analysis and clean implementation.
- 02Pattern-first practice: understand the technique before grinding volume.
- 03Every solved problem gets re-derived from scratch during revision.
- 04Live counts come from my LeetCode profile below, never from a hardcoded number.

Core CS
The subjects I am building depth in, and why each one matters to the engineer I am trying to become.
01
Operating Systems
Processes, threads, scheduling and memory — the vocabulary behind every performance discussion.
02
Computer Networks
TCP/IP, HTTP and latency budgets, the layer every distributed system is built on.
03
DBMS
Indexing, transactions and normalisation, where most backend bugs actually live.
04
OOP
Abstraction and design principles that keep large codebases changeable.
05
System Design
Trade-offs between consistency, latency and cost when a service has to scale.
06
Computer Architecture
Caches, memory hierarchy and pipelines — why the same algorithm can be 10x faster.
07
Mathematics
Discrete maths, probability and complexity analysis behind algorithm design.
08
