I'm a Full-Stack Software Engineer and AI-assisted product builder, currently pursuing a B.E. in Information Technology at Thakur College of Engineering and Technology (CGPA 9.3/10). I design and ship systems end-to-end — from relational/NoSQL data modeling and transactional backend logic to responsive, motion-driven frontends.
My engineering focus centers on three pillars:
- 🏗️ Full-Stack Product Engineering — building complete systems (auth, data layer, real-time events, deployment) rather than isolated features.
- 🤖 AI-Integrated Systems — structured, validated LLM output pipelines (Groq/Llama, Gemini) powering resume intelligence, interview analysis, and conversational advisory tools.
- ⚙️ Concurrent & Consistent Systems — atomic transactions, race-condition-safe reservations, and TTL-based state management under real concurrent load.
I care about code that survives contact with real users — not just code that works in a demo.

🎭 SeatSync — Event Seat Booking Platform
Production-minded MERN booking system built as a full-stack hiring assignment. Manages live seat inventory across events with ten-minute temporary reservations, atomic double-booking prevention via MongoDB transactions, and automated concurrency testing.
| Aspect | Detail |
|---|---|
| Stack | React 19 · Vite · Node.js · Express 5 · MongoDB Atlas · Mongoose · JWT |
| Scale | 300 seats managed across 3 concurrent live events |
| Performance | Server-driven countdown via expiresAt; TTL index + lazy seat cleanup for stale-state prevention |
| Security | JWT auth, bcrypt hashing, Helmet, CORS allowlisting, rate-limited auth routes |
| Impact | Concurrent reservation attempts resolve to exactly one success and one 409 Conflict — verified via automated integration tests |
| Repository | github.com/aryancodes12-bit/sortmyscene-booking-system |
Built around a MongoDB transaction that conditionally updates seats only while status: "available", using modifiedCount validation to guarantee no partial multi-seat reservation is ever persisted — the core consistency guarantee of the system.
🎯 PlacementOS — AI Placement Preparation Platform
A domain-oriented modular-monolith unifying DSA tracking, resume intelligence, interview replay, and a cross-domain readiness engine into a single preparation workflow for engineering students.
| Aspect | Detail |
|---|---|
| Stack | React 19 · TypeScript · Vite · Node.js · Express · PostgreSQL · Prisma · Firebase Admin · Groq SDK |

| Impact | 81 passing automated tests · 0 high/critical audit vulnerabilities · privacy-first browser-side audio extraction (no raw video upload) |
| Repository | github.com/aryancodes12-bit/PlacementOS |
Includes a structured AI output contract for interview analysis — scores, strengths/weaknesses, missed concepts, and root-cause diagnostics — parsed and range-checked before persistence, with retry/backoff logic for provider failures.
