  Senior Software Architect
As a Senior Software Architect, I led the development of a comprehensive solution to address the SEO business team's needs for managing and improving SEO rankings. By collaborating with the SEO team and various application teams, I designed and built a multi-tier application suite, featuring a Node.js back-end integrated with an ETL process. This process leveraged an Enterprise Service Bus (ESB) with Kafka for seamless data transmission to the Master Data Management system and individual application teams. I also architected the front-end using HTML5, Angular, jQuery, and Twitter Bootstrap, creating an intuitive interface that empowered the SEO team to drive significant improvements in rankings for over 2 million web pages. The solution enabled the SEO team to manage over 500,000 products and over 2 million individual pages, resulting in an organic revenue in excess of $400 million annually.

  Technical Expert
As a Technical Expert, I played a key role in the implementation of various business tools to streamline the prompt routing and payment of invoicing and financial documents throughout the company. Over the course of my career, I contributed to a project managed using a hybrid incremental and waterfall lifecycle methodology, leading and co-leading team of up to 30 developers. Each project was successfully delivered on time and within budget. The systems were built using Service-Oriented Architecture, handling millions of transactions daily to process large volumes of document requests, demonstrating their scalability and reliability. These systems supported invoicing for up to $2 billion per day, facilitated seamless integration with banks and financial institutions across multiple countries, and ensured robust performance and compliance across diverse global markets.
Selected Projects
  Property Insurance and Finance Platform Redesign LeaseLock
I led the redesign of a core system using TypeScript on Node.js with a PostgreSQL database on AWS, incorporating insights from past projects to enhance performance and reliability. Managing a team of five engineers, I prioritized data integrity through database-driven controls and ensured SOC2 and SOX compliance for financial and insurance reporting.
Collaborating with senior leadership, I strengthened the QA department to identify complex issues and partnered with cross-functional teams to redesign the invoice and insurance reporting system, addressing inconsistencies and financial inaccuracies. Within an 8-week timeline, we developed a reliable, repeatable process that resolved issues at the source, significantly reducing report generation time from weeks to hours while maintaining system integrity and performance.
  Search Engine Optimization Staples
I collaborated with the SEO and application teams to develop a comprehensive solution for improving SEO rankings. I designed and built a multi-tier application using Node.js, with an ETL process connected to an ESB utilizing Kafka to transmit data to the Master Data Management system and application teams. The front end, developed with HTML5, Angular, jQuery, and Bootstrap, provided an intuitive interface, enabling the SEO team to enhance rankings for over 2 million web pages.
I conducted extensive research into legacy systems to understand existing data and crafted an optimal solution. I implemented a Data Access Layer (DAL) with RESTful web services connected to MongoDB and Couchbase, and created an ETL process for SEO data documents. A security layer using TLS, AES encryption, and Active Directory ensured robust protection.
Additionally, I established coding standards, enforced GIT and NPM versioning practices, and mentored 15 developers, contributing to the success of the project and multiple successful implementations.
  Financial Solutions Management Tool Walmart
This project focused on implementing a business process management tool to streamline the routing of financial documents for approval or rejection, with approved documents directed to data entry teams. Managed over three years with multiple software releases, the project utilized a hybrid incremental and waterfall lifecycle methodology, involving a team of 30 developers. Each project phase was delivered on time and within budget, resulting in a Service-Oriented Architecture (SOA) system that processes 2 million transactions daily and handles 125,000 new document requests, demonstrating scalability and reliability.
Additionally, the project aimed to enhance the SAP Travel and Expense application by developing a more user-friendly, mobile-optimized front-end interface. The original SAPUI5-based application was rewritten in HTML5 with jQuery and JavaScript to address performance issues. A responsive design, powered by cascading stylesheets and JavaScript, ensured optimal performance across devices. The interface was integrated with SAP systems via AJAX, connecting to RESTful web services to guarantee robust and reliable performance, improving both development efficiency and speed to market.
