Omie Holley

Full-stack engineer with 10+ years taking products through their entire life — from ambiguous beginnings to production systems people depend on. Starts wherever the problem starts: user research, UX, data modeling, frontend, backend, or cloud infrastructure. Comfortable inheriting an undocumented prototype or a legacy monolith, and just as comfortable with a blank page. Ships, then keeps it healthy — monitoring, observability, root-cause debugging. Works hands-on at every scale: independently, embedded in a team, or leading one.

   • Gave a multi-billion-dollar rental client natural-language answers to why customers call — architecting their first production AI system end-to-end as sole architect: an AWS pipeline ingesting ~1,400 calls/day (Nice API → Transcribe → Batch Inference classification → data lake) with version-controlled classification, QuickSight dashboards, and a Lex + Bedrock executive chatbot; re-architected it when AWS shipped Batch Inference.
   • Closed the full product loop: used the platform's own data to find ~30% of inbound calls were unconfirmed cancellations, then owned discovery, built the frontend self-service cancellation flow, and specced the backend changes — cutting total call volume ~30%.
   • Built a Webpack 5 module-federation runtime-override system + custom browser extension for a 60-micro-frontend, 4-team platform where no lower environment matched production — letting any developer test changes against real production data, users, and auth in seconds instead of hours; also built a one-click, dependency-aware deployment tool that prevents human error.
   • Root-caused elusive cross-team production bugs by tracing correlation IDs from Amplitude into Dynatrace to the failing service (e.g., hardwired client-ID logic flagged for replacement with a configurable request flag).
   • Hardened cross-app authentication (34% fewer auth failures via feature-flag-gated token routing) and drove accessibility, performance, and end-to-end testing across customer flows.

   • Founding engineer on a greenfield ad-tech platform, working directly with the CTO, CPO, and COO on technical strategy and product direction.
   • Built and owned the reusable component library and design-system foundations from scratch, establishing the frontend patterns and conventions the team built on.
   • Implemented the Google DV 360 integration for campaign creation and updates — working through a dense, complex API — and modeled state/synchronization for work-in-progress campaign data.

   • Sole owner of product, design, and engineering for a digital tech-pack SaaS — interviewed designers, built user personas, mapped features and roadmap, and designed the full UI/UX (no dedicated PM or designer).
   • Built 95%+ of the full-stack app from an undocumented proof-of-concept to a documented, maintainable platform — shipping continuously to designers who used it live, and turning their feedback into specs and pixel-perfect mockups for myself and other engineers.
   • Designed the entire database and information architecture (re-architected to 3NF; migrated via AWS DMS with zero data loss); automated infrastructure and CI/CD via AWS CDK and remediated cloud security vulnerabilities.

   • Sole developer of a greenfield admin dashboard (Angular + TailwindCSS) for an enterprise device-security platform — letting system administrators monitor registered devices and surface behavioral anomalies through drill-down charts that filter into refined views.
   • Led the multi-phase migration from a legacy Apache Wicket (Java) monolith to a modern Angular + Spring architecture, collaborating on a distributed backend (Java, Spring, Apache Kafka event streaming, Karaf OSGi / ServiceMix).
   • Held the UI/UX quality bar on the product, refining design handoffs to accessibility and design best practices.

   • Sole developer for 1+ year of a SaaS scheduling, fleet, and ordering product — designed the entire database and information architecture and built the client portal, vendor-management platform, and React Native field-worker mobile app, owning the data model, frontend, and UX end-to-end while iterating on real user feedback.
   • Drove product planning — roadmaps, sprints, epics, and feature mapping — wearing both architect and product hats.

   • Flagged unprompted that a 20-store RFID loss-prevention POC was billing ~$119K/month, analyzed the billing myself, and cut it ~99% to ~$1.3K/month (~$1.4M/year saved) by refining the false-positive flagging algorithm embedded in the on-prem RFID readers to shrink Pub/Sub event volume — while hardening the architecture from POC to production.
   • Built a user-facing loss-prevention dashboard surfacing likely-stolen items with timestamps of when each product left its aisle and the store, over a real-time GCP Pub/Sub + DataFlow pipeline.
   • Led development of systems integrating RFID asset tracking, video/camera analytics, and facial recognition with front-end applications and in-store hardware.

   • Diagnosed and fixed a critical validation/parsing defect in a logistics/shipping batch system that was silently corrupting data — preventing over $10M/day in losses.
   • Lead developer across multiple supply-chain applications on a team of eight; modernized the frontend from AngularJS to Angular for performance and maintainability.
