Levi Smith

The Situation

Tasked with standing up AI/ML capabilities inside a payments infrastructure company with zero prior ML footprint. Had to build team processes, tooling, and delivery culture from scratch.

What I Did

• Led a cross-functional AI team delivering LLM-based and classical ML solutions for tokenization, fraud detection, and internal productivity
• Stood up MLOps practices: model versioning, experiment tracking, CI/CD for model deployment
• Partnered with product and compliance to scope AI features that met PCI-DSS and SOC 2 constraints
• Coached engineers transitioning from backend development into ML engineering

The Result

Delivered production AI features on a platform processing billions of transactions annually — with auditability, compliance, and engineering rigor baked in from day one.

The Situation

Inherited a legacy MVC front-end powering a $20M+ ARR SaaS product. Performance was degrading, feature velocity was slowing, and the team was burning out on spaghetti jQuery code.

What I Did

• Designed and led migration from legacy MVC to React SPA with component library
• Introduced sprint ceremonies, code review standards, and CI/CD pipelines
• Managed multi-tenant front-end delivery across enterprise customers with divergent requirements
• Mentored 4 engineers; 2 promoted to senior roles during this period

The Result

Cut front-end build times by 60%, reduced production UI bugs by 40%, and restored team morale — all while shipping features on a live platform with zero downtime migration.

The Situation

Led digital ad operations and web platform management for a global B2B events company. The ad stack was manual, error-prone, and couldn’t scale with the business.

What I Did

• Built and managed a team delivering 1,000+ ad campaigns/month across hundreds of advertisers
• Architected automated ad trafficking workflows that eliminated manual insertion orders
• Managed 30+ revenue-generating websites (10k+ pages) with a combined $30M annual revenue footprint
• Introduced analytics dashboards that gave sales teams real-time visibility into campaign performance

The Result

Transformed a reactive ad ops function into a scalable, metrics-driven operation — reducing campaign setup time by 70% and increasing ad revenue attribution accuracy.
