Case study

Loytag — a SaaS backend, end to end

A property-management and loyalty platform handling complex relational data and a stack of third-party integrations. The most complete system I’ve owned so far:

Schema
High-normalisation PostgreSQL design with partitioned tables for transaction logs.
Payments
Stripe Connect for multi-tenant subscription management and payouts.
Messaging
Twilio-powered SMS notifications and OTP verification.
Deployment
Dockerised services with CI/CD pipelines targeting Oracle Cloud.
Loytag platform — guest engagement dashboard

Performance work I’m proud of

450 ms → 120 ms

API response times

Query optimisation and payload compression across the hottest endpoints of the Loytag platform.

Multi-layer caching

Redis plus application-level LRU caches with deliberate eviction policies.

Queue-based async processing

Moved heavy work off the request path, keeping the event loop free.

Jaipur Engineering College (RTU) ↗
