Summary

AI deployment engineer candidate, Codex power user, and senior-level enterprise software engineer with 8+ years shipping customer-facing systems at Equitable. I use Codex and Claude Code/Opus daily, build AI-assisted products in public, and bring the customer-facing enablement background to help engineering teams adopt AI coding tools across their SDLC. Recent work includes Vibe Storefront, Gridiron Rumble, Postede, PortDeck, and AI workflow explainers.

Experience

Senior Software Engineer July 2017 — Present

Equitable · Syracuse, NY

Use Codex and Claude Code/Opus as part of my daily engineering workflow to accelerate planning, implementation, debugging, and legacy modernization while keeping enterprise security, SDLC, and compliance constraints in view
Rapidly prototyped the PCR Rates page in days when business stakeholders were stuck in abstract requirements discussions, then led the production redesign that now drives thousands of daily views and generated hundreds of thousands of dollars in business impact
Used AI-assisted modernization to migrate RIG, a 10+ year-old Angular 1 retirement-planning app with outdated dependencies and security vulnerabilities, into a modern AEM component while preserving the core calculator behavior in ~3 weeks
Migrated 150 pages from Sitecore to Adobe AEM with zero downtime, collaborating with vendor teams to compress an originally 9-month migration plan into roughly 3 months
Drove the enterprise CMS through 3 major version upgrades (Sitecore 9.1 → 9.3 → 10.2 → 10.3), organizing data migration processes, issue tracking, and cutover readiness
Led chatbot development with Microsoft Bot Framework on Azure, serving as lead engineer and managing the project backlog from prototype through MVP
Served as lead engineer across major customer-facing web initiatives, taking projects from requirements and stakeholder alignment through implementation, production launch, and post-launch reliability
