Backend Engineer

Dear hiring team,
I understand that the central requirement for this Backend Engineer role is designing dependable APIs, data models, transactions, and asynchronous workflows with explicit failure behavior. I am motivated by backend work where clear contracts and observable failure behavior let the rest of the product move safely.
I performed this work as Backend Engineer. I implemented schema validation in a Node.js ingestion API before publishing to Kafka. I used PostgreSQL reconciliation to detect acknowledged but unpersisted events. I moved acknowledgment after durable enqueue and eliminated the loss in timeout replay tests.
In that same role, I also owned the following work. I improved distributed systems reliability by testing retry storms and delayed consumers. I used Redis expiry bounds and a dead-letter queue to isolate poison messages. I verified that valid customer events continued processing during recovery.
I would welcome the opportunity to discuss the decisions and delivery I owned, and how I could apply that experience in this role.
Sincerely,
J. Lee
