I build apps people
actually want to use.
I work with founders and small brands in wellness, education, and parenting — from first idea to launched product, with focus and care.
StoryLoom
weave immersive fictional worlds
Writers, artists, game designers, and filmmakers often know the feeling they want to create before they know the story. StoryLoom turns that feeling into a complete fictional world — characters and their archetypes, setting, central mystery, aesthetic layer, soundscape with a curated Spotify playlist, an opening paragraph, and a full story outline. Six atmospheric genres, ten unique worlds each. The complete storyworld downloads as a formatted PDF writing companion.

Sense & Letters
a Jane Austen correspondence generator
What if Darcy wrote to Miss Bates? What if Anne Elliot corresponded with Emma Woodhouse? Sense & Letters pairs any two characters across Austen's four major novels and generates a five-letter exchange — each voice distinct, each situation drawn from the Regency world. The full correspondence downloads as a styled PDF keepsake.

Tuck Me In Stories
personalized bedtime stories for little ones
Parents build their child's story the way a child would tell it — filling in names, ages, and favorite things in a Mad Libs-style wizard that gets more specific with every screen. The result is a unique AI-generated story narrated by a warm voice, accompanied by gentle classical piano. Intimate, unhurried, and designed to send little ones drifting off.
Almost ready. Email me for early access.
America Through the Ages
a history notebook for curious students
Most history apps present information. This one asks students to build it themselves. America Through the Ages lets middle schoolers construct their own American history timeline from scratch — drilling down from era to century to decade to individual event — adding notes, key moments, and custom fields as they learn. Color-coded by era, fully responsive, and designed to feel like a personal notebook rather than a database.
The student's own voice and organization sit at the center of the historical record.

Tend.
a daily wellbeing app for dementia caregivers
Caregivers spend all day making decisions for someone else. Tend asks nothing of them — just a gentle daily checklist, a journal prompt, and a moment to breathe. No advice, no noise, no overwhelming resources. A few minutes each day that belong entirely to them.
Almost ready. Email me to join the founding member waitlist.

One project. One launched product.
I work on one project at a time, start to finish. You bring the idea. I handle the product thinking, UX, design, and build. You get my complete focus and a launched product on the other side.
— Step 1
Scope, structure, and design. We align on exactly what we're building and why before a single screen is built.
— Step 2
Build, refine, and launch. Full working product, deployed and ready for users.
— Investment
Starting at $5,000. Fast turnaround is my default — most projects land in two to four weeks depending on scope.
