Project Impact
This project demonstrates my ability to handle complex system requirements, implement scalable architecture, and deliver high-performance solutions with refined frontend user experiences.
What I Learned
I mastered the management of extensive race conditions and pessimistic database locking to guarantee atomic ledger integrity during concurrent wallet transactions. Additionally, I gained deep experience implementing API idempotency keys to eliminate double-spend and duplicate charge scenarios under high-concurrency bidding environments.
