Creative writing

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.

Creative writing / Literature

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.

Family / Early childhood

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.

Education / Music

Coda

master music history, one era at a time

Most quiz apps test memorization. Coda teaches understanding. Students preparing for AP and college music history exams quiz themselves across five centuries, from the Renaissance through the Contemporary period, with every question paired with a detailed explanation that turns each answer into a short lesson. Built on a Supabase backend with a subject-agnostic architecture — the same engine could be repurposed for any subject simply by swapping the underlying data. Features include era-based study paths, progress tracking with streaks and accuracy scoring, missed question review, and a favorites system, in both light and dark mode.

Wellness / Caregiving

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.

How it works

One project. One launched product.

I take on a limited number of projects, so each one gets my full attention. You bring the idea, together we shape the direction, look, and feel, and then I build it.

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.

Let's build something.

I'd love to hear about your project.
