20+ years across product engineering, frontend systems, and full-stack delivery.

Selected impact

• Apply production engineering judgment across varied code, architecture, debugging, and documentation tasks.
• Identify weak assumptions, hidden failure modes, and gaps between plausible output and sound engineering.

Selected impact

• Migrated Create React App and Heroku to Next.js and Vercel with no downtime and zero known launch defects.
• Reduced migration risk by mapping dependencies across the React application, Django services, AWS infrastructure, deployment environments, and external integrations; established staging, production-like rehearsal, backup, rollback, and monitoring procedures.
• Improved delivery velocity by approximately 30%, onboarded an additional engineer, and coordinated delivery across Product, Design, Infrastructure, QA, and Customer Success.
• Used evidence-based coaching to surface engineers’ strengths and ownership; an underestimated engineer later earned a promotion after my tenure.

Selected impact

• Rebuilt team capacity during a leadership transition, helping grow the engineering group from two to four contributors while maintaining delivery for an established public platform.
• Strengthened testing and regression-prevention practices, contributing to a 50% reduction in regression volume during the first three months.
• Delivered new administrative capabilities in under two months while advancing Section 508 accessibility and reusable frontend standards.

Selected impact

• Grew the team from three to six engineers and supported three promotions within 18 months.
• Stabilized DisputeFlow 2 and led its evolution into DisputeFlow 2.1 with configurable custom fields, reusable content snippets, flexible templates, reporting, document generation, and rule-driven workflows.
• Partnered with Operations and Product to replace a spreadsheet-dependent workflow with a React and Node.js platform delivered in approximately two to three weeks, saving roughly 295 hours of manual entry per month.
• Designed and built most of a standalone Node.js ingestion service that collected daily files through secure SFTP, normalized incompatible schemas, validated records, handled failures, and delivered data through the existing platform API.

Selected impact

• Designed and built a production Node.js controller for a globally deployed Bitcoin ATM bill recycler, using finite-state-machine architecture to translate a timing-sensitive binary serial protocol into safe cash-management workflows.
• Delivered 39 REST endpoints, operational recovery controls, and integration across hardware behavior, external APIs, transaction state, and physical cash movement.
• Produced approximately 95 pages of technical documentation so the system could be operated, maintained, and extended safely.

Selected impact

• Built leadership and delivery capacity across multiple, primarily offshore project teams while remaining involved in architecture and hands-on product work.
• Took a custom casino operations platform from stakeholder conversations and paper models through architecture, full-stack implementation, third-party integration, testing, remote deployment, staff training, and production launch in approximately nine months as the sole developer of the initial release.
• Independently reverse-engineered ten legacy C++ and DirectX slot titles and built a reusable HTML5 and CreateJS engine separating shared game state, weighted outcomes, wager and credit flow, paylines, payouts, assets, animation, and events from title-specific rules.

Selected impact

• Redesigned a fragmented association-website delivery process into a reusable, parallel model that reduced the first full discovery-to-launch lifecycle from approximately 22 months to two to three months.
• Supported at least eight website launches through the model while enabling two engineers to independently lead association sites in parallel.
• Built reusable Kentico, JavaScript, HTML, and CSS foundations and transferred the process through pairing and documentation.
