Senior software engineer delivering secure, high-availability Java and cloud systems for healthcare, defense, and financial platforms.
United StatesWhat I'm looking for
I’m a Senior Software Engineer with 7+ years delivering secure, high-availability solutions across healthcare, defense, and financial systems, including CJIS-aligned implementations and cleared-environment work with an active Secret clearance.
At JPMorgan Chase, I designed and implemented a CJIS-compliant backend service with Java, Spring Boot, and PostgreSQL, cutting query latency by 47% across 12 endpoints. I engineered CI/CD pipelines with Jenkins, Docker, and Kubernetes to reduce deployment time from 2 hours to 18 minutes, and I strengthened compliance by integrating LDAP SSO and OAuth with audit logging that passed a customer compliance review with zero findings.
I also modernized data ingestion and APIs at Flatiron Health—boosting throughput by 220% with Java, Spring Boot, and Kafka, reducing processing lag from 6 hours to 45 minutes, and improving response times by 61% across 15 endpoints. I advanced reliability by diagnosing memory leaks via JVM profiling and tuning GC to reduce out-of-memory incidents by 78%, while raising pipeline pass rates to 94% through TDD and integration testing.
Earlier, at Raytheon Technologies and as a Google intern, I built embedded telemetry components and distributed data pipelines, then optimized performance through low-level debugging, query tuning, and containerized tooling. I care deeply about secure coding, observability, and mentorship—leading teams to faster delivery, fewer defects, and stronger operational outcomes.
Experience
Work history, roles, and key accomplishments
Designed and implemented a CJIS-compliant backend service with Java, Spring Boot, and PostgreSQL, reducing query latency by 47% across 12 endpoints. Built CI/CD with Jenkins, Docker, and Kubernetes (2 hours to 18 minutes for 6 microservices), improved transaction throughput by 33%, and enabled LDAP SSO/OAuth with audit logging supporting a compliance review with zero findings.
Revamped oncology data ingestion services using Java, Spring Boot, and Kafka, increasing throughput by 220% and reducing processing lag from 6 hours to 45 minutes. Modernized REST APIs and PostgreSQL performance (61% faster across 15 endpoints), implemented tenant-aware audit logging, and automated releases to eliminate 95% of manual deployments while reducing OOM incidents by 78%.
Developed embedded telemetry components in C++ and Java on Linux for aerospace subsystems, increasing data capture fidelity by 29% across flight tests. Built backend aggregation services with Spring Boot and PostgreSQL (ingesting 1.2M daily sensor records), reduced release cycles from 3 weeks to 9 days, and resolved 92% of critical defects prior to system integration through low-level debugging an
Contributed to a distributed data pipeline in Java and Kafka, validating designs that processed 50,000 events per minute under peak load. Improved quality and performance by rewriting SQL (nightly ETL runtime down 72%), increasing test coverage by 38%, reducing environment setup time by 85%, and decreasing staging crash rate by 67%.
