AI workforce platform

Scaling an AI-driven workforce platform past $1M ARR with 95% retention.

The brief. Build the product, customer success and integration strategy for an AI platform connecting learners, education institutions, employers and workforce agencies. Make it work at the scale of public funding — where uptime, accuracy and auditability matter as much as features.

The work. Defined and streamlined a human-in-the-loop AI process using multiple LLMs so the team could scale operations without trading away quality. Managed the due-diligence, acquisition and post-merger integration of an outcomes-tracking product in the education market. Oversaw integrations across Stripe (payments), Salesforce (CRM) and Ellucian (ERP), pushing and pulling data via REST APIs to match client requirements.

First-wave online banking

Launch the very first online banking system in the world.

The brief. Build and support the systems that would let Wells Fargo customers access their accounts over the internet — at a moment in the mid-90s when most banks were still arguing about whether the web mattered.

The work. Built and supported the systems that made online customer-account access real, working through the unfamiliar trade-offs of an entirely new channel: security model, customer authentication, integration with the bank's core, operational handoffs, and the support patterns required to run something the rest of the industry didn't yet know how to run. The resulting platform became one of the foundational pieces of Wells Fargo's online presence — and reduced ongoing maintenance costs by more than a quarter.

Semiconductor manufacturing data systems

Building the data-collection backbone for IBM's Advanced Semiconductor Technology Center.

The brief. Stand up the on-site engagement at IBM's ASTC: design, build and support the data-collection systems that captured information from the semiconductor manufacturing lines — where accuracy and reliability were not negotiable, and where downstream yield and quality decisions depended on the data being right.

The work. Managed an on-site team of six engineers designing, testing and developing applications running on top of IBM's micro-kernel product. Owned resourcing, delivery and the day-to-day client relationships across IBM and EDS. Designed and developed the data-collection systems that ran against the manufacturing lines themselves, feeding the analytics that informed yield, quality and throughput decisions at one of the most demanding manufacturing environments in the world.
