Job Description

At Dell Technologies, I architected and led the development of a comprehensive microservices ecosystem focused on global address management and rule validation systems. My primary achievement was the complete rewrite of a 10+ year legacy address system, transforming it into a modern, scalable solution supporting multiple countries with 24/7 availability.

Key Projects and Responsibilities

Global Address System Architecture: Designed and implemented a flexible, multi-country address validation system using Elasticsearch as the primary database. The system supported diverse data ingestion methods including CSV files, text files, and external APIs, with each country implementing custom business rules while maintaining a unified data interface.

Microservices Development: Built several microservices including rule engines, email validators, and phone number validators, all following a consistent architecture pattern with Oracle databases and Elasticsearch caching layers. Developed reusable NuGet packages that reduced code duplication by 40% across teams.

Legacy System Modernization: Successfully migrated a complex Japanese address processing system with intricate character validation rules, implementing incremental modernization strategies and comprehensive automated testing to ensure functionality preservation during the transition.

Infrastructure and DevOps: Led the migration from private cloud infrastructure to Kubernetes, collaborating closely with DevOps teams to establish robust CI/CD pipelines, monitoring solutions using ELK Stack, and ensuring high availability for global operations.

Technical Leadership: Provided mentorship to development teams, conducted architecture reviews, and established best practices for distributed systems design, focusing on maintainability, scalability, and operational excellence in a 24/7 global environment.
