"I don't just learn technologies. I build systems to understand them."
A Computer Applications student and software developer interested in understanding systems across multiple layers — web applications, developer tools, cybersecurity, AI-assisted systems, embedded systems, human-computer interaction, and systems engineering in general.

An evidence-first, reproducible investigation system — ingests evidence, keeps it immutable and content-addressed, and represents findings as explicit, structurally-linked claims rather than bare conclusions, so a case can be exported and independently reproduced.
Python SQLite CLI
A full-stack civic technology platform: turns a citizen's free-text complaint into a structured, trackable civic report, routes it through the right jurisdiction, and follows it to resolution — with an AI-assisted understanding layer and a governed workflow underneath it.
React FastAPI Gemini SQLite
A full-stack news aggregation and analysis application. Pulls live articles from an external news source, generates AI-assisted summaries, and lets signed-in users save and revisit them from a personal dashboard.
React Node.js Express MongoDB JWT Gemini
A Smart India Hackathon 2026 project, built with Team Ekadanta: a bionic wheelchair steered through eye movement and jaw-clench detection, communicating over Bluetooth to a separate motor/obstacle-detection unit. My contribution covers the signal-acquisition and control layer — reading the input signals, the master↔slave communication link, and the embedded motor/obstacle-detection integration. Private repository, built as a team.

Technologies I've worked with — not a claim of expertise in all of them.
Bachelor of Computer Applications (BCA) — currently pursuing
Current focus is on strengthening the fundamentals underneath the frameworks: Data Structures & Algorithms, Operating Systems, Computer Networks, Database Systems, Object-Oriented Programming, Software Engineering, Computer Architecture, Cybersecurity fundamentals, and Mathematics for Computer Science.
Understand the fundamentals, not just the frameworks built on top of them.

Not every project here is a finished product — some are working applications, some are experiments, some are research-oriented explorations of an idea. The point in each case is learning through building it, not just reading about it.
- Stronger computer science fundamentals
- Better software engineering practice
- Systems and security
- AI/ML
- Embedded systems
(This is a direction, not a measured proficiency chart — no progress bars here.)
I don't want my GitHub to be a collection of tutorial clones.
