Matan Dessaur
Matan DessaurBuilder by day. Curious the rest of the time.

I learn, I create, I share, and I live a little

I develop experiences, mostly on the web, with AI woven through everything: studied, sharpened against, embedded. I have an eye for UI and UX and I take it seriously, and I trust the user enough to hand them something unique, the way a cook trusts a touch of umami to change the whole dish. By day I lead a team of developers. The rest of the time I collect what sharpens me: ideas, visions, perspectives, and the tools I swear by. That collection became Tooolbox.

Mindsteps

From anxious thoughts to calm next steps. A board sorts what you take on now, later, or have already done, and a Calm tab of breathing, grounding and focus exercises is there for when starting feels like too much.

Aléoresto

A restaurant roulette for wherever you are: one tap picks somewhere open right now, as far as you feel like walking, biking or driving. Roll for two sends a friend a link and lands on a place you both want, and a dinner reminder asks before you default to the usual.

Product — in the making

Cadence

Every AI agent you use, in one room, sharing one brain. A Mind that never forgets a decision. Local models thinking in the background. A voice that answers when you talk. Nothing ships until it is proven. It plans, designs, builds, debugs and presents.

Featured challenge

10 sites in 10 days

Ten complete websites, shipped in ten days. I built an AI-powered workflow that combines intelligent agents, context building, and automation to develop exactly the way I would: code standardization, full content generation, Sanity CMS, and Next.js best practices, every time. Each site is a plug-and-play solution. It is like having my own development team working at lightning speed. Every site is live, so open them and click around; the content in them is placeholder.

I like being on top of the wave. And when I fall, I fall like a snowboarder: controlled, up fast, back on the snow.

Past experiments

Retired, remembered

Not everything I build stays online, and that is the point. Each of these was a question I wanted to answer. They are offline now, but every one of them left something behind in how I work.

  1. 2024One Good ThingA daily gratitude PWA: one good thing a day, nothing more. Taught me how far a single well-made interaction can carry an app.
  2. 2024IOUBill splitting and expense tracking gamified with Gemini. Proof that money apps do not have to feel like spreadsheets.
  3. 2023Simpl AIA deliberately tiny GPT chatbot, built when the API was brand new. The exercise was restraint.
  4. 2023//DoubleSlashNote-taking for developers: syntax highlighting, autosave, search. The notes app I wanted while learning.
  5. 2023Gym SchedulerA fitness management system for trainers: clients, notes, communication. School project that outgrew its brief.
  6. 2023MatchingCoffeesA dating app matching people on coffee preferences. Silly premise, serious full-stack build.
  7. 2022Essmei BandanasAn e-commerce storefront for handmade bandanas. Early lessons in catalog, cart and checkout flows.
  8. 2022whatsaround.meA local exploration companion suggesting spots tailored to your taste. Its restaurant corner later grew into Aléoresto.
  9. 2022webcity.dev → ontheweb.agencyAn agency built with a friend. When his life got too busy, it grew into my solo practice, ontheweb.agency: websites, web experiences, internal tools, and more.

Photography, cooking, life.

Open Instagram

I trained as a photographer before I wrote software for a living, and it still shows in how I build. When I am not shipping, I am behind a camera chasing light, at the stove testing a recipe on people I love, or on a mountain somewhere waiting for the snow to come back. That side of life, the unfiltered one, lives on Instagram.
