Dear [Hiring manager's name],
At Meridian Trust Financial I own 14 Spring Boot microservices on our core payments platform, clearing 3.2 million transactions a day at 99.99% availability, and I'm applying for your Java Developer role because that combination of real scale and a strict reliability bar is exactly where I do my best engineering work.
I reduced p99 latency on our funds-transfer API from 840 milliseconds to 190 by tuning G1 garbage collection, eliminating N+1 Hibernate queries and adding read-through Redis caching. I also led our Java 8 to Java 21 migration for 4 monolith modules serving 900,000 customers, sequencing every cutover carefully behind feature flags with zero release-day incidents anywhere.
I designed an outbox-pattern event pipeline on Kafka that ended a whole class of dropped-settlement defects, cutting reconciliation exceptions from 120 down to under 5 a month. I mentor 3 mid-level developers through structured, regular code review, and 2 of them earned real promotions within 18 months of working closely with me.
I'd welcome a longer conversation about where [Company name]'s Java services could use that same latency and reliability focus. I'm glad to walk through the Kafka outbox design or the Java 21 migration in more detail. Thank you for your time.
Sincerely,
Blake Chen
