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.

Work experience

Software Engineer at Lumber, Jul 2024 - Present · 2 yrs 2 mos, Bengaluru, Karnataka, India, -> Own Kafka infrastructure end-to-end re-architected payroll processing onto an event-driven pipeline (~7x throughput), and built a custom debouncing + backpressure layer after Kafka Streams fell short. Running in production since. -> Designed the event-lineage and reliability layer: interceptor-based observability, at-least-once delivery via manual offset management, idempotent handlers, durability tuning across environments. -> Built the earning-rate computation engine: taxes, reciprocities, prevailing wages the most complex domain logic in the system. -> Optimized PostgreSQL migrations to avoid table locks (fast-path ADD COLUMN, NOT VALID constraints, CREATE INDEX CONCURRENTLY) for zero-downtime schema changes. -> Diagnosed and fixed production incidents: a JPA fetch-graph OOM (~1,085 entities/request) and pod crashes traced to RDS autovacuum IO saturation exhausting the Tomcat thread pool. -> Added Redis caching and distributed locking; built scheduled jobs with Quartz.
