02 — Things I build
Nights and weekends, I design, build and ship my own products end to end — a baby log, a name finder, a household watchlist, our family operating system, the course scheduler I started in college, and a tracker-comparison lab.

Miara
Know what your baby needs next.
A calm baby tracker that shows the next bottle and the next nap before you need them. Log in one tap or by voice, and everyone who looks after your baby sees the same log. Free, with no ads and nothing to buy.
Next nap, next bottle
From the last 10 days of the log, Miara works out when the next nap is likely and when the next feed usually comes, and shows the window beside what’s typical for the age. A heads-up lands on the Lock Screen 15 minutes ahead.
One tap, or just say it
Diapers take one tap. A bottle starts at your usual amount and the current time, so you only change what’s different. Or tell Siri, Claude, ChatGPT or Gemini, which can answer from the log too.
Everyone in sync at handoff
Invite a partner, grandparent or nanny. Whoever has the baby logs it, and everyone else sees it right away, with who added or changed each entry.
The patterns you’re too tired to notice
Miara reads the whole log, so nights that ran 35 minutes shorter after a late last nap show up without anyone remembering last Tuesday. Each finding comes with what the AAP and CDC say is typical.
First foods, growth and the doctor
Count toward 100 first foods with the nine allergens in view, and a flag when a symptom keeps following one food. Weigh-ins land on WHO growth charts beside medicines and questions for the doctor.
A book for every month
Say what happened in a line and add a photo. Each month, Miara gathers the memories and first tastes into a book. This one is real, from our own family.

NameWise
Baby names, picked for you. Chosen together.
An AI naming assistant for expecting couples. It learns your style, roots and must-haves, deals name cards that explain why they fit, and sharpens with every swipe. Match on a first name, then find the middle that flows.
It asks before it suggests
A few short questions on style, roots, meaning and popularity, plus the names you already love. Must-haves, like a starting letter, are rules, not hints.
Every card makes its case
Each name comes with a match score, its meaning and a line on why it fits you. Love, like, pass or add a note, and the next batch gets sharper.
Swipe apart, match together
You each swipe privately. When you both love a name, it's a match, and your partner gets a push. Every like lands in your library with notes and matches.
Then, the middle name
Lock in a first name and NameWise suggests middles scored on how the full name sounds with your surname. Swipe them the same way, together.

WeWatch
What to watch, together.
A shared watchlist for two. Each partner picks favorites and describes their taste; Claude blends both into fresh picks every week, says why you'll like each one, and shows where it's streaming.
For you, tonight
Each of you picks favorites and writes what you love. Claude blends both into tonight’s picks, each with IMDb and Rotten Tomatoes scores, and one sentence reshuffles the lot when you want something lighter.
One list, in your order
Everything you both want to watch lives in one ranked list, shared across iPhone (SwiftUI with Liquid Glass), Android and the web; press and hold to reorder. Coming Soon puts new seasons of the shows you love on a calendar, so nothing slips past.
Remember what you loved
Rate what you finish as Loved, Liked or Meh. Every rating sharpens the next round of picks, and the shelf becomes a record of everything you’ve watched together.

PreslerOS
Our family, handled.
Our family operating system: to-dos, groceries, trips and holidays, and a Mac at home that actually does them. Hand it a to-do and it comes back with a plan, then books the table, fills the carts or watches the flights, asking again before it pays, books or sends anything. Talk to it, or just chat. Built for one household, ours.
The day, drawn
Today opens on our street under today's sky, with one line on what matters: fog till 10, Paris tonight. Below it, only what's left, and the few things that need us.
Hand it a to-do, get a plan
Hand the agent a to-do and it comes back with a plan. After Go, it works in that to-do's own chat, asks when it needs a choice, and shows the booking once more before it confirms.
Two carts, one Approve
One shared grocery list. The Mac fills a Costco cart and a Safeway cart, each item where we usually buy it based on a year of order history, then waits for one Approve.
Trips that run themselves
Booking emails from Gmail file themselves into trips, family visits included. On the day, the Lock Screen counts down to when to leave, and flight changes arrive as a push.
Birthdays and holidays, handled
Birthdays, anniversaries and holidays count down with who's on them and what's already bought. The agent suggests gifts, and a gift for one of us stays hidden on their phone.

Fitbit Dual-Wear Compare
Two trackers. Know which to trust.
For anyone wearing two or three trackers at once. Connect Fitbit, Strava, Polar or Oura accounts, pick a day, and heart rate, steps, sleep and workouts line up on one timeline, with the disagreements flagged and scored.
Every beat, overlaid
Minute-by-minute heart rate from each device on one chart. Red bands mark where they split, and PE10 scores how often they land more than 10 bpm apart.
Sleep, stage by stage
Each device’s night stacked as a hypnogram. The agreement rate shows how often both called the same stage; the duration delta is the gap in total sleep.
Run against run
Pick a workout from each device to see distance, calories, elevation and route error side by side, with heart rate overlaid. Pair a Polar strap and it becomes ground truth.
