Description
ECOS is a Bitcoin mining ecosystem where users can start cloud mining, rent or buy ASIC hardware, track profitability, manage balances, and withdraw funds without maintaining mining infrastructure themselves. The platform includes a user dashboard, financial workflows, ASIC marketplace, payment integrations, and internal admin tools.
Task
The API had performance bottlenecks under load because of heavy synchronous operations, limited caching, and inefficient database queries. Critical workflows needed stronger idempotency, validation, rate limiting, and auditability. Financial transactions, mining reward updates, contract statuses, and marketplace deals required more reliable processing to prevent duplicates, race conditions, and manual admin errors.
Solution
Reworked backend flows around transactions, queues, and background jobs. Optimized database queries, added indexes, introduced caching, and moved heavy operations into asynchronous processing. Strengthened API security with stricter input validation, role-based access control, rate limiting, audit logs, and idempotent financial operations. Improved internal monitoring and admin workflows for handling edge cases and production incidents.
Results
The platform became more stable under growing traffic, API responses improved across user and admin scenarios, and financial workflows became safer and more predictable. Manual intervention decreased, duplicate operations and inconsistent statuses were reduced, and the team gained clearer production diagnostics.
