Clarity is a form of care

I've spent nearly 20 years building for the web, the last ten at Alkami. I spent about seven of those on the architecture team, which we called Vanguard, building the platform's frontend and the Iris Design System. Now I lead the Admin Platform team, which took me from frontend into full stack work: .NET services, Kubernetes, and a healthy amount of legacy ASP.NET Framework. Most of my days are about making big systems easier to live in, and holding the line on accessibility and localization so the banking software we ship works for everyone who uses it.

Lately that also means bringing AI into how my team works. I use BMAD-method agent workflows for spec-driven delivery, and I build agent skills that write code documentation and encode our architecture standards.

I chaired Alkami's Synergy DEI committee through June 2025, and I'm part of SheTO, a community of women and non-binary engineering leaders.

Work

Admin Platform Modernization

Alkami Technology · Technical Lead, full stack · 2023–present

Leading the Admin Platform team meant moving from frontend into full stack: .NET services, Kubernetes, and the legacy ASP.NET Framework application itself. We're migrating those legacy features to microfrontends. Along the way we rolled out Cloudflare caching that cut static asset transfer costs about 8%, and brought AI-assisted, spec-driven agent workflows into how the team delivers. I also represent web frontend architecture on Alkami's Technical Architecture Committee.

Frontend Architecture

Alkami Technology · Vanguard architecture team · 2016–2023

On Vanguard, I set frontend architecture direction for the Alkami Platform with Architecture, Product, and Security. I designed a CDN delivery layer for platform assets on AWS (S3, Lambda, CloudFront) and owned frontend build tooling, bundling, and caching decisions.

Iris Design System

Alkami Technology · Vanguard architecture team

Built the Iris Design System component library in TypeScript, adopted across Alkami products, and led the platform's accessibility work from WCAG 2.0 to 2.1.

AWE App Management Portal

Bottle Rocket · Lead Front End Developer · 2013–2016

Led frontend on AMP, the CMS behind the AWE video platform for NBC Universal. I also architected the AWE Apple TV app and the Chromecast receiver used for HGTV.

Texas Instruments · Web Developer · 2010–2013

Led a developer team on TI Education's website redesign, moving it from a table-driven TeamSite layout to a fully tableless HTML5 site on Sitecore.

Open Source

Most of this started as "I wish my house could do that." All of it lives on GitHub.

Book

Finding Jensen: A Path to Empathy Through Understanding

My memoir about empathy and inclusion. The idea at its center is the same one I bring to engineering: clarity is a form of care. Whether it's an API, a design system, or a hard conversation, I want the other person to be able to actually receive what's being said.

I built the pipeline that turns it into print, eBook, and web editions, and narrated and produced the audiobook myself. A sequel, Seeing Jensen, is in progress.

Contact

If you're working on design systems, accessibility, or thoughtful ways to put AI to work, I'd love to talk. Or if you just want to chat about home automation, I'm always up for that too. Email or LinkedIn is the best way to reach me. 🌱☕️
