Work Experience
Senior Java DeveloperJanuary 2024 – PresentHudson Clearing Technologies, Jersey City, NJ
- Cut the nightly settlement batch from 5 hours to 70 minutes by rewriting the Spring Batch job to partition by clearing member and replacing row-by-row JDBC updates with bulk upserts.
- Own four Spring Boot microservices for payment settlement and reconciliation that process about 3.5 million transactions a day at p99 latency under 120 ms.
- Leading the split of a shared Oracle schema into service-owned PostgreSQL databases, migrating 11 of 19 tables so far with Flyway and dual writes and no customer-facing downtime.
- Eliminated duplicate payment events by adding idempotency keys and a transactional outbox between the settlement service and Apache Kafka, ending a recurring manual reconciliation task.
- Raised test coverage on settlement services from 48% to 82% by introducing JUnit 5 and Testcontainers suites that run against real PostgreSQL and Kafka in the Jenkins pipeline.
- Designed the REST and OpenAPI contracts for a real-time balance API used by three internal teams and two bank partners, versioned so existing clients never broke.
- Review pull requests for a team of six, wrote the team’s Spring Boot service template and mentor two junior developers through their first on-call rotations.
Java DeveloperJune 2021 – December 2023Passaic Valley Insurance Group, Parsippany, NJ
- Built five Spring Boot REST services for policy quoting and endorsements, replacing a monolithic Java EE application module by module over 18 months.
- Cut quote API response time from 1.8 seconds to 400 ms by adding Redis caching for rating tables and rewriting three N+1 Hibernate queries.
- Moved 14 services from Ant to Maven with a shared parent POM, standardizing dependency versions and ending build failures caused by library conflicts.
- Integrated the policy platform with two third-party rating vendors over SOAP and REST, adding Resilience4j circuit breakers so vendor outages no longer stalled quoting.
- Fixed 40+ SonarQube critical issues and three Spring Security findings from a penetration test before the annual security audit.
Associate Software EngineerJuly 2019 – May 2021Brookhaven Logistics Software, Edison, NJ
- Developed Java and Spring features for a warehouse management system used by 70 distribution centers, including a wave-picking API and two carrier label integrations.
- Wrote 300+ JUnit and Mockito tests for the order allocation module, which had no coverage, ahead of a refactor that shipped with no regressions.
- Tuned slow Oracle SQL reports using execution plans and new indexes, bringing the daily inventory report from 12 minutes to under 2.
- Fixed production defects in a two-week Scrum cadence as part of the support rotation, closing 85 tickets in the first year.

Tailor my resumeWhy This Resume Works
- The summary gives the stack and the scale together (Java and Spring Boot, 3.5 million transactions a day, p99 under 120 ms), which is the first thing an enterprise Java hiring manager checks.
- Bullets lead with the result and then name the engineering mechanism ("Cut the nightly settlement batch from 5 hours to 70 minutes by rewriting the Spring Batch job to partition by clearing member"), giving an interviewer something concrete to probe.
- Keywords from Java postings (Spring Boot, Spring Batch, Maven, REST, SQL, microservices) appear inside bullets as well as in the Technical Skills section, so an ATS match is backed by evidence of use.
- Reliability and quality work is shown with specifics: idempotency keys and a transactional outbox for Kafka, and test coverage raised from 48% to 82% with Testcontainers.
- The progression from associate to developer to senior is visible in ownership: features in one module, then five services, then four production services, a schema migration and two mentees.
Common Resume Mistakes
- Listing only Java version or framework without outcome.
- Missing Spring, SQL, or build keywords.
- No scale or performance metrics.
