QsrSoft · Lombard, IL (remote)

• Designed an agentic development pipeline in Claude Code now used by six engineers across three repositories, cutting two-to-three-day ticket turnaround to same-day close.
• Serves as front-end subject matter expert for a live platform used by close to a million people: sets technical direction, and is the team's go-to on component architecture, interaction standards and code quality.
• Serves as SME for charting and data visualization (Highcharts), owning the presentation layer for data-heavy operational dashboards: the screens customers run their business from.
• Builds reusable component libraries against a shared design system, applying WCAG accessibility, responsive layouts and cross-browser compatibility while building rather than as a later pass.
• Helped plan and drive a Vue 2 to Vue 3 migration across 60+ engineers, alongside a monorepo-to-microservices move, writing shared components and repeatable patterns for other teams, teaching Vue 3 and simplifying the process to shorten the learning curve. Finished in about a year, with no disruption to customers.
• Advocates surrounding AI-written code with tests that check for explicit behavior, built into the pipeline, where tests are written against behavior a developer has verified.
• Partners with product owners, designers and leadership to scope ambiguous requests into deliverable work; mentors junior and mid-level engineers through pairing and review.

• Led brainstorming sessions with engineering teams to drive new ideas and reduce technical debt.

Dogtopia · Phoenix, AZ

• Built enterprise React.js applications and managed enterprise microservices on Node.js, Azure, MySQL and MongoDB, contributing to over $100M in revenue.
• Achieved a 60% average decrease in load times through code splitting, lazy loading and efficient state management.
• Designed reusable React component patterns integrated with design systems, improving development efficiency by 25%.
• Implemented Google Cloud functions that improved customer retention and reduced bounce rate and run time.
• Ran system audits and feature-feasibility discussions with third-party vendors, franchisees and stakeholders.

Jimmy John's · Orem, UT

• Ran the location with full operational authority whenever the general manager was away: roughly 25 direct reports, 2 to 20 staff on shift.
• Owned the full people lifecycle: hiring, termination, training, scheduling and day-to-day performance management, plus inventory and ordering.
• Stepped back from the manager role in 2020 to retrain as a software engineer through Lambda School, and moved into engineering full-time in 2021.

• Commercial CRM for mobile auto detailers: a React Native app, a Vue 3 owner dashboard, public booking sites and a Node/Postgres backend. Designed, built and shipped alone in under three months.
• Camera-based plate recognition, route optimization with Mapbox, a QR pay page for Cash App, Venmo, PayPal and Zelle (no card processing, by design), barcode inventory, and multi-tenant scoped permissions over customer financial data.
• Anthropic API integration that ingests a business's advertising flyer and generates a claimable booking page carrying their real prices and services.

Prototype for a small FBO (anonymized) · read the case study →

• Turned a one-workbook-per-month Google Sheets process into a working prototype in a couple of days. Each sheet became its own report with data entry, laid out the way staff already track it, plus filters and comparison across months.
• Anthropic API natural-language questions over the operator's own numbers, with the known gaps in their records written into the prompt so the model never reasons from books it doesn't know are incomplete.
• In-place editing of the public site: fuel prices, wording, and which third-party detailers and mechanics are listed. Demoed to the owner and his successor; not adopted yet.

Lambda School (now BloomTech)

• Intensive full-stack program covering JavaScript, React, Node.js, relational databases and full-stack application development.
• Certifications: Full-Stack Web Development · Technical Interviewing.
