B.Tech CSE (AI & Data Science), Class of 2026. Looking for my first full-time Software Engineer role — backend, full-stack, or AI. Based in India, open to relocation.

I like the unglamorous parts of software: idempotent webhooks, retries with jitter, race conditions, token budgets. The work nobody notices until it's missing.

1. My software is in production. PaperCheck AI grades handwritten CA/CS answer sheets and is used daily by coaching faculty — ₹15–21 per paper against the ₹100–190 human evaluators charge, in minutes instead of 2–3 days.
2. Google merged my code. PR #26884 in google-gemini/gemini-cli, approved by a Google maintainer — picked up from a help-wanted issue.
3. TCS CodeVita Season 13: global rank 2028 out of 100,000+ participants — top ~2%.

Grades batches of handwritten CA/CS answer sheets in parallel — one streaming AI worker per student — and returns annotated, examiner-style PDFs. In active daily use.

• Layered reliability: 10-step jittered exponential backoff, zero-output-gated stream restarts (no paper graded twice), bounded auto-resume for paused long runs
• Browser-direct streaming, so multi-minute model runs never hit serverless timeouts
• SHA-256-keyed prompt cache (6 h TTL), 50 MB signed-token PDF uploads, strict token budgeting on Gemini Flash

An all-in-one learning platform for CA students: AI tutoring over chat, voice, and TTS, a notes library, a social feed with DMs and stories, study rooms, leaderboards.

• ~85K lines of TypeScript — Next.js + React 19, 29+ API routes, 26+ dashboard pages
• Security enforced at the database: 34 tables, 85 row-level-security policies, 18 SECURITY DEFINER RPCs on Supabase Postgres
• Three-model Gemini fallback cascade (a degraded answer beats downtime), SSE streaming chat, per-IP sliding-window rate limits with Retry-After

Event-driven admissions automation on the official WhatsApp Cloud API: FAQs, demo booking, payments, doubt triage to faculty, and a daily MCQ engine.

• HMAC-SHA256-verified webhooks with constant-time compare; fast ACK, async processing
• Message-id idempotency absorbs Meta's webhook redeliveries; full-jitter retries with transient-vs-permanent error classification
• WhatsApp's 24-hour messaging rule enforced at a single outbound choke point; 16-entity Prisma/PostgreSQL schema; runs credential-free in stub mode

A role-based academic portal, and a 15-endpoint complaint system built in a three-person team through PRs and code review. Database-level race-condition fix proven by a concurrency test, Hibernate N+1 fix with a regression guard, Spring Security, Docker with MySQL health checks, CI via GitHub Actions and Jenkins.
