Maven → GradleArchitecture, trade-offs and measurable outcomes — the engineering story behind the metrics.
How a config-driven integration layer onboarded 20+ insurers inside a 15-day government deadline without writing new integration code for each insurer.
A real-time calculation pipeline designed for throughput and latency, using Kafka-driven async processing to power revenue-critical flows.
Standardized quarterly settlements with idempotency, auditability and validation to eliminate repeat-processing errors and reduce reconciliation effort.
Moved PDF generation away from synchronous request paths into an asynchronous pipeline with dead-letter handling while meeting a sub-3-minute SLA.
Full-stack products demonstrating API design, authentication, state management and data modeling.
Social platform with posts, image uploads, likes and threaded comments with protected REST APIs.
Video streaming app with Google OAuth 2.0, JWT session management and protected React routes.
E-commerce application covering catalogue, cart, order flow and JWT-secured accounts.
