Professional Experience
LeaseLockMay 2015-Jan 2025
Senior Director of Architecture and Solutions
As the Senior Director of Architecture and Solutions, I led the
design and implementation of an insurance management system to
provide security deposit alternative insurance for property
management companies, focusing on delivering scalable,
maintainable, and high-performance solutions. I collaborated
closely with key stakeholders, including the Chief Financial
Officer, Vice President of Insurance, property management
partners, and team leaders from various departments, to ensure
that the solutions aligned with the company’s overall business
objectives.
In this role, I managed and guided cross-functional teams,
including engineering, product, and business teams, ensuring
effective communication and coordination throughout the project
lifecycle. I was responsible for overseeing the technical
direction, managing resources, and aligning multiple teams to
ensure timely delivery of complex features and functionalities.
Additionally, I provided strategic oversight for the architecture
of the solution, ensuring it was both adaptable and scalable to
meet future demands. Through strong collaboration and leadership,
I drove the successful execution of projects, maintaining a
balance between technical excellence and alignment with business
goals. My leadership enabled the system to meet both business and
regulatory requirements while supporting business growth and
enhancing operational efficiency.
Staples, Inc.Jan 2015-Mar 2021
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.
Wal-Mart Stores, Inc.May 2001-Dec 2014
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.
