What I'm looking for

I’m looking to build scalable, fault-tolerant backend and data platforms where correctness matters—especially event-driven pipelines and compliance-heavy payments. I want ownership, fast iteration, and a team that values mentorship and reliable engineering.

I build financial-grade, event-driven systems that prioritize correctness, resilience, and scale. At Real-Time Data Platform, I architected an Auth & Settlement pipeline with Kafka and Spring Boot to process millions of transactions/month, delivering cross-DC resilience and deduplication guarantees.

I also modernize legacy workflows into compliant, high-throughput processors—rebuilding 15K+ lines of SQL into an FDA-compliant data processor and cutting creation latency from 3 days to near real-time. I design fault-tolerant architectures with circuit-breaker logic and DLQ-driven zero data loss, and I ship full-stack reconciliation tooling (React, Java, MySQL) plus accessibility improvements aligned to WCAG 2.2.
