Backend Engineer @Lumber \| Building the payroll infra nobody notices

## About

Backend engineer at Lumber, building the event\-driven systems behind construction payroll\. Java · Spring Boot · Kafka · Redis · PostgreSQL · AWS/EKS I own our Kafka infrastructure pipelines that move millions in payroll for thousands of construction workers every week\. Payroll doesn't get a maintenance window, so the job is as much operating the system as building it: delivery and durability guarantees, event lineage, a custom debouncing layer, back\-pressure so it degrades instead of dying\. Also Redis\-based distributed locking and caching, and scheduling with Quartz\. Before Kafka, I built our earning\-rate computation engine: taxes, reciprocities, prevailing wages\. Still the most complex piece in our system\. Two years ago I was writing basic Node\. Now I debug Java at the framework level, and I spend more time on "should we build this" than "how\." Currently going deeper on distributed systems and software architecture\.
