Flagship Case Study: Deep Dive
Overview & Problem Solved
Consolidates fragmented online savings into a single interface. Automates affiliate verification and coupon discovery through direct API integrations and push notifications, ensuring users instantly capture maximum cashback value.
Key Features
Features double-entry wallet bookkeeping, multi-level fraud-resistant referrals, real-time push deal suggestions, and automated transaction reconciliation to prevent reward attribution leaks.
Technical Architecture
Asynchronous Flutter client (Dart) connected to high-throughput FastAPI server. Integrates PostgreSQL database with query index optimization, Firebase for JWT Auth, and auto-scaled AWS cloud nodes.
Challenges Solved
Prevented referral gaming and ensured data consistency under high concurrent load by implementing double-entry PostgreSQL transaction ledgers with JWT verification and non-blocking background workers.
Production Highlights
Successfully deployed high-performance REST APIs integrated with Razorpay gateway for automated withdrawals. Inspected with automated security controls and verified test pipelines.
Future Roadmap
Integrating a local-first offline offer cache, purchase history-based AI recommendations, and OCR-powered receipt scanning for offline merchant cashback validation.
Software Engineering Excellence
How Kashandaz is engineered under-the-hood to ensure security, performance, and long-term maintainability.
⚙ Architecture
Clean architecture using separation of concerns. Flutter frontend utilizes Bloc/Provider patterns, keeping business logic distinct from rendering interfaces.
🔌 Backend APIs
Built with asynchronous FastAPI endpoints utilizing Pydantic for request validation, achieving fast request-response cycles and robust documentation.
🔐 Authentication
Integrated Firebase Authentication for passwordless/OAuth social logins coupled with secure server-side JWT verification for API access controls.
🗄 Database Design
Relational database models in PostgreSQL with transaction isolation levels, strict foreign keys, and indexes on lookup tables to guarantee data integrity.
⚡ Performance & Scalability
Heavy utilization of caching, database pool pooling (e.g. asyncpg), and optimized JSON payloads to minimize processing latencies and cloud infrastructure overhead.
🚨 Error Handling & Monitoring
Global exceptions middleware, standardized error contracts, centralized logs, and active crash reporting filters to detect and patch issues proactively.
