Code, ship,
break, repeat —
the loop never
exits.
Priyan Rajarajan — CS undergrad at SRMIST. I build full-stack tools, backend systems, and the occasional Windows utility. Comfortable on either side of the API.

I build across the stack — and I like the messy parts.
CS undergrad at SRMIST. I spend most of my time shipping web apps, working with databases, building browser extensions, and occasionally tinkering with Windows tools when the mood hits.
Lately I've been into scheduling problems, making sure things don't fall apart when they get busy, and figuring out where AI actually helps — and where it just gets in the way.
Off the keyboard: hackathons, research on air quality, and helping run IEEE CS at SRMIST.

Selected releases
13 entriesCampusClean
Student-first campus issue reporting for SRMIST. Students submit waterlogging, elevator, escalator, washroom, and other campus problems with photos, fixed campus locations, and floor details; coordinators verify, progress, resolve, reject, export, and download report PDFs from a focused queue. Role-aware Auth.js flows, OTP setup, hashed passwords, Prisma + PostgreSQL, reward points for useful reports, status timelines, Recharts analytics, and photo uploads via Cloudinary or local fallback.
QueryCraft
Learn databases by doing, not reading slides. QueryCraft is an all-in-one practice studio — run SQL in-browser with sql.js, build ER diagrams, walk through normalization, explore relational algebra and tuple calculus, and spin up synthetic tables on demand. Client-first with Zustand-persisted state; lightweight API routes only for seed datasets and health checks.
Full-stack scheduling platform for SRMIST with role-based workflows for Faculty, HODs, Admins. Priority-driven scheduling engine with conflict resolution + concurrency-safe slot allocation via PostgreSQL row locking and Redis. Google Calendar, push notifications, NextAuth + WebAuthn.
Not another manual CGPA calculator — GradeSnap is the first image-based OCR tool built for SRM students. Upload a screenshot of your portal results page and it extracts every subject, credit, and grade locally in the browser, then calculates SGPA or CGPA for you. No typing rows by hand. Review, edit if needed, and you're done.
