Senior Software Engineer, Visa Jun 2022 – Aug 2025

Engineered and optimized high-throughput Java (Spring Boot + Micronaut) microservices for the Visa Advanced Authorization (VAA) fraud detection platform, reducing transaction latency by 35% and improving fraud scoring turnaround to under 120ms.

Refactored critical scoring pipelines leveraging Kafka Streams for asynchronous event processing, boosting throughput from 15K to 30K TPS.

Implemented caching strategies with Redis Cluster and Hazelcast, reducing redundant DB lookups and cutting compute costs by 22%.

Integrated AI-driven anomaly detection models via TensorFlow Serving and OpenAI API embeddings, improving fraud catch-rate by 8%.

Re-architected RESTful APIs to gRPC for inter-service communication, improving payload efficiency by ~40%.

Deployed infrastructure using Terraform + AWS EKS, ensuring auto scaling and multi-region fault tolerance.

Configured CI/CD pipelines with Jenkins and ArgoCD, reducing deployment time from 40 to 10 minutes.

Implemented observability stack (Prometheus, Grafana, ELK) with automated alerting for performance regression detection.

Collaborated with data science and risk teams to integrate new machine-learning features into production fraud scoring.

Mentored 6 engineers on JVM performance tuning, distributed tracing, and asynchronous messaging patterns.

Contributed to Visa’s internal blockchain experiment for cross-border payment integrity using Hyperledger Fabric for audit tracking. Software Engineer, CareBridge Jan 2018 – Jun 2022

Developed and maintained scalable Python (FastAPI) and Java Spring Boot microservices integrating with Epic, Cerner, and Allscripts EHR systems.

Architected secure, HIPAA-compliant REST APIs for clinical data exchange; improved average response time from 850ms to 320ms.

Led AWS migration of 30+ services to ECS + RDS + Lambda, achieving 99.9% uptime and automated scaling under load.

Automated infrastructure provisioning with Terraform and implemented secrets rotation using AWS Secrets Manager.

Integrated AWS Comprehend Medical for NLP-based entity extraction to enhance patient data analytics.

Implemented event-driven messaging using Kafka + S3 to asynchronously process EHR sync jobs, reducing queue delays by 50%.

Built CI/CD pipelines using GitHub Actions + AWS CodeBuild, cutting release time by 65%.

Designed monitoring dashboards (Grafana + CloudWatch) to visualize API and ETL pipeline performance.

Collaborated with security teams to achieve SOC2 Type II and HIPAA compliance through code audit automation.

Containerized legacy Python monoliths with Docker, cutting deployment footprint by 40%.

Contributed to pilot project integrating AI triage assistant using OpenAI’s GPT API to improve call center response accuracy. Software Engineer, TechNova Consulting Aug 2015 – Dec 2017

Developed full-stack Java (Spring Boot, Hibernate) and Angular applications for financial client portals handling millions in transactions.

Migrated Java EE monoliths to Spring Boot microservices, enabling parallel team deployments and reducing downtime by 60%.

Implemented CI/CD pipelines using Jenkins + Docker + Nexus, automating builds, tests, and versioning.

Built internal invoice tracking and delivery system for a retail logistics client using Java + Kafka + React, improving SLA adherence by 25%.
