First Tech Federal Credit Union

Senior Technical Product Manager · October 2023 – Present. Internal platforms and integrations across Fiserv, Mastercard, Alkami, Velera, and OSG.

API Strategy Versioning

Decoupling legacy APIs

Led decoupling of legacy APIs serving both member-facing and employee-facing use cases. Identified which capabilities were safe to expose externally (read-only account data) versus internal-only (account closure, sensitive write actions), then set the versioning and rollout sequence so internal tools could ship independently of member-facing surfaces.

Tool Architecture Business Case

20,000 hours of internal time recovered

Traced the loss to how the customer-service tools were built: manual handoffs, redundant approvals, and missing integrations. Quantified the cost, built the business case, and now lead the redesign as a top organizational priority — automating handoffs, connecting card processing and core banking directly, and simplifying the screens reps work in.

Performance APIs

API performance remediation

Alongside the tooling redesign, investigated why core internal APIs were slow — over-fetching, redundant calls, sequential requests, unoptimized database queries. Quantified the impact and secured leadership prioritization for the fixes.

Write APIs Vendor Orchestration

Member-servicing write APIs

Defined requirements for the write APIs employees use to act on a member's behalf — closing accounts, issuing cards, handling disputes, resetting passwords and lockouts, retrieving documents — across Fiserv, Alkami, Velera, Mastercard, and OSG. Coordinated delivery across onshore, offshore low-code, and vendor engineering teams. Security is layered: trusted-source IP allowlisting, token-based authentication, and rate limiting.

AI · Agents Build vs Buy

Internal AI agent, 1,000+ daily questions

Product vision and rollout for an internal AI agent (Pega Knowledge Buddy) handling 1,000+ daily questions from customer service reps. Built the business case, made the build-vs-buy recommendation, and ran the adoption push. Saves roughly 1,200 hours a year.

Delivery Enterprise Priority

Simplification — 51 features in 2025

Led Simplification, a top enterprise priority communicated regularly by the CEO. Delivered 51 features across the year — matching the total output of the rest of the PM department combined.

Operations On-call

Production incident response

On-call experience firefighting production incidents at the layer where outages can mean a member can't access their funds.

Prior roles

Fintech operations, integration work, and customer-facing roles before product.

GreenFi (formerly Aspiration Financial)
Technical Program Manager
Led integration with Galileo's core banking APIs to automate card replacement — now processing tens of thousands of cards per year. Shipped 14 features across internal operations and customer-facing tools; the most recent beat its projected efficiency gains by 55%. Negotiated a standing 15% engineering allocation for technical debt in a regulated fintech environment.

Oct 2023
GreenFi
Customer Engagement Manager
Led an operations team of up to 40 through a cash-flow crunch: new headcount wasn't approvable and tooling investments wouldn't pay off in time, so the ask was more work, faster, on overtime alone. Per-agent output rose 68% through targeted coaching and product gaps fed back into the roadmap. Also caught two fraud attacks before the dedicated fraud team did — a retrospective estimated millions in prevented losses.
