Mar 2025 – Jul 2026

Vice President, Business Analytics & Reporting

Mariner Finance — Nottingham, MD

Quality Assurance, .NET Applications, Business Intelligence, Data Warehousing

Responsibilities

• Promoted to Vice President of the Business Analytics & Reporting organization, succeeding the former VP upon his advancement to SVP / CTO and continuing to report to him.
• Assumed leadership of the organization’s four teams (Quality Assurance, .NET Applications, Business Intelligence, and Data Warehousing), broadening scope beyond data and reporting into application development and quality assurance.
• Directed strategy, priorities, and delivery across all four functions, working through each team’s leadership while continuing to mentor and develop leads.

Projects

• Python ETL Platform — Architected and built a Python framework to replace our SSIS stack. The goal was to get ETL out of opaque DTSX packages and into plain, testable code that AI coding tools can help write and maintain. The framework handles configuration, execution telemetry, checkpoint-based restarts, retry logic, schema and row validation, notifications, and slowly-changing dimensions. Jobs are organized by domain in a single registry-driven repository with scaffolding tools, unit tests, and documentation. Telemetry feeds into Lighthouse, so Python jobs get the same monitoring and alerting as the SSIS jobs they replace, with nothing losing visibility during the migration.
• Lighthouse — Solely designed and built the initial release of a SQL Server monitoring platform, then handed it to the .NET Applications team for ongoing development. Lighthouse gives us one operations dashboard across the database estate: SQL Agent job tracking with automatic failure detection, statistical identification of long-running jobs, SSRS/PBIRS subscription and Power BI refresh monitoring, and interactive job-flow visualizations with live status updates. It also tracks Matillion Data Productivity Cloud pipelines, unifying failure reporting across SQL Agent, SSIS, and DPC as the warehouse team migrates off Matillion ETL. Built on ASP.NET Core and Vue 3 with Active Directory role-based access. It grew out of the job-alerting tooling my team had built years earlier.

Apr 2021 – Mar 2025

Business Intelligence Manager / Assistant Vice President

Mariner Finance — Nottingham, MD

Business Intelligence

Responsibilities

• Led the Business Intelligence team through a period of significant expansion, with the role growing out of Team Lead as headcount and scope increased.

• Shifted emphasis from hands-on development toward management and mentoring, growing the team’s technical depth and autonomy.
• Personally absorbed the bulk of production support and escalations so the development team could stay focused on building and delivering.
• Received the President’s Club award for a second time.

Projects

• AWS Data Platform Build-Out — Initiated and led the company’s move onto AWS for data warehousing, built on Redshift with Matillion ETL. The initiative started inside Business Intelligence and eventually became a dedicated Data Warehouse development team with its own team lead, separate from BI.

Mar 2018 – Mar 2021

Team Lead

Mariner Finance — Nottingham, MD

Business Intelligence

Responsibilities

• Provide leadership for and manage the daily activity of the Advanced Analytics and Warehousing team.
• Database Administration, Modeling, and Planning in order to maintain a highly scalable platform.
• Participate in off-hours on-call support.
• Analyze existing SQL queries for performance improvements and re-engineering when necessary.

• SQL Job Alerting — Designed an alerting platform monitoring SQL Server Agent jobs and PBIRS subscriptions, generating proactive notifications for failed and long-running jobs so issues could be addressed before downstream reporting and data flows were affected.
• SSIS Documentation Tool — Built a tool that inventories every SSIS project deployed to the server, decomposes the DTSX package XML into a queryable database structure, and surfaces it through a web interface so the team can search deployed code and embedded queries without opening packages in Visual Studio. This became the foundation for multiple server and deployment decommissioning projects, completed with minimal to no issues.

Mar 2017 – Mar 2018

Engineer

Comcast Cable Communications — Nottingham, MD (Northeast Division)

XOC

Responsibilities

• Enhancing and bug-fixing applications based on JIRA intake tickets that are prioritized by company priorities and cost savings.
• Break/Fix solutions for existing applications and server infrastructure.
• Rewriting legacy applications with a modern design, theme, layout, and database structure.
• Managing SQL Server and Windows Server clusters used by divisional and national applications, as well as other departments and teams.

Projects

• Server Architecture — Comprised a plan to reduce SQL Server cluster from 12 servers down to 6, as well as redistribute and maximize resource throughput of these servers. This plan is being implemented throughout Fiscal 2018 and saves the company a few hundred thousand dollars as well as minimizes necessary maintenance times while ensuring resources are properly utilized.
• Subcounts — Analyzed an aged and outdated application written in classic ASP, and rewrote it to use MVC, Razor, and jQuery. Database backend had to be completely re-engineered as there was little to no documentation or scripts that existed for the old platform. Application regularly processes over 800M records in under 2 minutes per execution depending on parameters used. This application interfaces with a ticketing platform to allow writing the output results into various tickets for customers, service incident reports, service maintenance logs, etc.
• OAUTH2 Rollout — Wrote an OAUTH2 wrapper that I used to bolt on to all existing and new applications to interface with external API’s. I then utilized this system to rewrite all applications to utilize this OAUTH2 system where appropriate.

Apr 2009 – Mar 2017

Lead Analyst

Comcast Cable Communications — Nottingham, MD (Beltway Region)

Collections, Revenue Operations, Finance, Business Intelligence

Responsibilities

• Reporting and Application Development for the Beltway Region of Comcast. Originally developed in Reporting Services, many reports were redesigned, revamped, and pushed into Tableau for Senior Leadership to consume.
• Managed local SQL Server cluster, including database modeling and indexing. This consisted of 8 SQL Servers, with 4 of these being dedicated to various operational data stores branched by department. This cluster would process several TB of data daily and needed to have high availability due to being used to drive critical business decisions.
• Hosted various training classes on SQL Query development in SQL Server and Composite Information Server. This empowered 41 employees to get into basic SQL Query development and to look at enhancing their skills. Follow-up support was provided over email with “Tips and Tricks” sent regularly, as well as individual query debugging with employees.

Projects

• Beltway OrderPath — Pulled in all orders made in the billing system to audit for previous bad debt or unreturned equipment. Application interfaced with credit bureaus and public records companies to obtain necessary information. Fuzzy matching was used to match non-standard addresses and recursively search through the billing system, checking for over 16 different data-point matches. This tool reduced a manual process from 30 minutes per account down to 2 minutes per account in an easy to use web interface for documentation, and reduced bad debt by over $2M in the first year of launch and handled over 100,000 orders a month.
• Beltway Friends and Family — An application that was used to generate one-time use coupons for employees to provide to their friends and family for special promotional deals.
• Customer Experience Portal — Every business wants to answer that question: “Would you recommend us?”, and this application was an answer to that customer lens. The application is a combination of data processing and data entry from leadership teams to provide employees a way to see what drives the customers experience with our business.
• Customer Notification Platform — Wrote an automated process that audited the billing system and looked for any equipment that had been returned. A detailed email would be generated and sent to the customer listing the individual devices returned and when, providing the customer a digital transaction receipt.
• Data Warehouse — Assisted in building a regional data warehouse. This warehouse was used to feed other departments, Reporting Services reports, as well as Tableau reports. Around 600gb of records were processed daily.
• QuickCoach — From techs in the field, to agents in the call center, a necessity exists to notify either side when there are issues with accounts or work orders that may have been overlooked or were unnecessary. This application allowed notifications to be sent to individual managers to improve our customers experience, as well as increase our team’s awareness.
• Service Authorization — Automated scripting process to generate a list of accounts and devices that are receiving services illegally, receiving less service than the customer is paying for, or receiving more service than the customer is paying for. This was then provided to MIS for auditing and processing, to correct the issues. This lead to a huge increase in internet subscribers as theft of service was very common. Process was extensible so that it could be used for any necessary customer notification.
