I have 15+ years turning dense, high-stakes software into products people can actually use. I own design end to end, build and scale design systems, shape AI-powered experiences, and build working prototypes myself.

An AI-powered threat-intelligence platform I designed and built. It turns a flood of security data from 20+ sources into clear, prioritized, explainable signals, keeping analysts in control of automated decisions, with review, override, and trust built into the interface.

A booking and dispatch platform I designed and built end to end across client, driver, and owner roles. Complex multi-step workflows and real-world edge cases, with business rules as configurable settings. Built with AI as a design and development partner.

An app I designed and built for my own kids: a virtual puppy they care for every day for six months before getting a real dog. Real walks, a streak that never pauses, real prices and vet guidance, and a parent dashboard, all simple enough for a 9-year-old to use on their own.

Public library books delivered to senior communities. Designed for readers in their 70s to 90s, with large type, voice search and read aloud, plus apps for facility staff, drivers and the owner, and privacy built in: every book is tracked, but nobody's reading is.

An app I designed and built for my own kids: they scan the cans they collect, a parent confirms what the machine accepted, and Connecticut's 10¢ deposit splits into saving, investing and giving. One family bag shared fairly, pickup places with a give-back share, and honest impact numbers.

A trading analytics platform. I designed real-time market heatmaps, complex filtering, and dense data tables into a clear, scannable interface, and built a scalable design system so the product stays consistent as it grows.
View case studyI am a senior product designer who owns problems end to end, from discovery and research to a shipped, high-quality product. I work across complex B2B, fintech, and enterprise domains, build and maintain design systems, and partner closely with product and engineering so design decisions survive real constraints.
I learn new domains quickly, communicate clearly, and hold a high bar for craft and detail. I am reliable to work with: I do what I say, meet my deadlines, and care about the outcome, not just the deliverable.
I began a cybersecurity pivot in early 2026 and have been contributing real work since — detection rules in production rulesets, independent threat analysis, and tools I build when a question needs one.
I write and contribute detection rules to Sublime Security and SigmaHQ production rulesets, focused on email threats and macOS techniques, each one cross-checked against reviewer feedback so it adds real coverage without overlapping what already exists.
Alongside the rules I built ArgusX, a threat-intelligence platform, and I am preparing for the CompTIA Security+ exam.
When a question needs a tool, I build one. Each is a working prototype you can try.
I am looking for a senior product design role where complex problems are the point, ideally in security, AI, fintech, or another technical domain.
