— things that run without me babysitting them —
AI exam-grading platform — 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 by coaching faculty.
- 💸 ~85% cheaper than human evaluation — ₹15–21/paper vs the ₹100–190 evaluators charge, in minutes instead of 2–3 days
- 🧠 Two prompt-caching layers — SHA-256-keyed explicit cache (6 h TTL) +
cache_controlprefix reuse to hold cost down - 🛡️ 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 — multi-minute model runs never hit serverless timeouts
24/7 admissions automation — FAQs, demo booking, payments, doubt triage to faculty, and a daily MCQ engine.
- 🔐 HMAC-SHA256-verified webhooks (constant-time compare) · fast ACK + async processing
- ♻️ Message-id idempotency absorbs Meta's webhook redeliveries · exponential backoff + full-jitter retries with transient-vs-permanent error classification
- 🚦 WhatsApp's 24-hour policy enforced at a single outbound choke point with graceful degradation — policy limits never crash the service
- 🗄️ 16-entity Prisma/PostgreSQL schema · timezone-aware cron jobs · runs fully credential-free in stub mode
