Experience

Development Manager - Summit Professional Education

Dec 2021 – Present

Senior-most engineer for a platform serving 533K accounts and 3.5M+ enrollments across all 50 states. Full-time through Aug 2026, retained since as an independent architecture advisor.

• Understands complex systems deeply enough to steer projects around broken assumptions and prevent expensive rework.
• Remodeled data to drop page loads from over 10 minutes to under 1, so the sales team now demos it for customers.
• Turned a one-line directive to switch marketing platforms into an actual specification, cutting a weekly per-user export from 115 fields to 24.
• Owned the subscription flow from a SaaS platform through webhooks into a near-real-time access-grant cache fed by 60K+ annual paid invoices.
• Recovered revenue from a week of failed payment processing by scripting batch retry and overcoming a broken vendor library.
• Orchestrated business-critical data and event processing pipelines through 140+ AWS Lambdas and SQS messaging at near-100% measured availability.
• Eliminated complex table joins behind near-minute search times with zero frontend changes, implementing a denormalized table and daily caching.
• Implemented new AWS Personalize, AWS CloudSearch, and Pipedrive integrations, and maintained and evolved the platform's broader integration surface spanning Recurly, Iterable, ON24, HubSpot, and Podbean.
• Recovered organic search from ~30th to a consistent top 10 after an SSR regression, directing a specialist's fixes across ~300 server errors and 600+ Core Web Vitals issues.
• Executed Vue 2→3 upgrade and UniVerse system retirement, one feature at a time, without additional funding.
• Built a structured context system the team's AI assistants read, moving cross-system knowledge out of my head and into the repo.
• Wrote the architecture and frontend standards the team's AI tools and engineers build against, after years of enforcing them only in review.
• Walked an engineer through a nine-month Vue 2 to 3 migration by asking questions instead of answering them.
• Mentored a bootcamp-trained developer into a full-stack engineer who owns website direction and decides what ships in each release.
• Translate system realities into decisions a non-technical CTO can act on, holding the technical half of that partnership.
• Split ownership of projects, applications, and release planning among three engineers while providing a safety net through every code review.

Software Engineer - Juice Plus

Jun 2020 – Dec 2021

• Took sole ownership of an undocumented, business-critical Java ETL and traced it from the source to become the team's subject-matter expert.
• Prototyped a bridging API unifying five disparate databases behind a single business-entity interface (Hapi, TypeScript, Prisma), learning the full stack from scratch to build it.
• Evaluated Go for the next-generation platform and recommended against adoption despite its technical fit, citing the org-wide rollover cost for an all-Java team.

Software Engineer - Atos / Syntel (Client: Fedex)

Sep 2014 – May 2020

• Operated a Tier 1 XML document storage application, holding 60TB of mission-critical system data in two data centers.
• Analyzed root cause of client system problems beyond the application I owned during solo 24/7/365 support.
• Built the runtime-configurable data layer behind an internal InfoSec risk-scoring system, a field model returning confidence scores on signals like IP, location, and domain.
