What I'm looking for

I'm looking to lead architecture and delivery of secure, scalable cloud-native Java platforms, contribute to AI evaluation workflows, mentor teams, and solve high-impact enterprise integration, data, and real-time messaging challenges.

I've led the design of secure, cloud-native enterprise applications at Tavant, including client onboarding and transaction-management workflows built with Java, Spring Boot, Kafka, AWS, Kubernetes, and Terraform.

At NEC Corporation, I led development for multi-modal biometric and identity-management platforms supporting fingerprint, palm, face, and iris workflows. I contributed to architecture, API-driven integrations, authentication and authorization, quality reviews, mentoring, and production support.

At Epsilon, I built scalable backend systems, real-time messaging capabilities, and centralized data workflows using Kafka, Apache NiFi, Kylo, SnapLogic, AWS, MongoDB, DynamoDB, and Snowflake.

Across 14+ years of Java development, I've delivered enterprise applications spanning utilities, content management, gaming, workflow automation, and gateway platforms. I also contribute to AI model evaluation through coding-task validation, rubric-based scoring, trajectory analysis, and deterministic output verification.
