Dmitrii

I take websites, apps and AI tools all the way to a working link.

I help venue owners and small teams get a website that takes orders, check a technical release, or build a practical tool. Below is only what you can open and verify yourself.

Selected work

Six projects that show best what I do. Each has a live page or a release, and the status is stated plainly.

Trinity projects

The t27.ai home page: “Trinity S³AI”, with “Open the map” and “How to play” buttons

Ternary compute stackIn development

Trinity (t27.ai)

Team project

The problem
A verifiable path from specification to silicon for ternary arithmetic and AI.
My role
Business co-founder: capital, partnerships, market entry. Dmitrii Vasilev is the engineering co-founder and the author of the t27 compiler. I also contribute code: per GitHub, 243 of my pull requests had been merged into public repositories as of 7 October 2026.
Outcome
A public site with a map of tasks and .t27 specifications, open repositories and CI. The project is under development; hardware and frequency data are not given here.

Trinity Check screenshot: GGUF file check with verdicts from four runtimes

Web tool and pilot serviceWorking

Trinity Check

My project

The problem
People who pick or publish local language models need to know quickly whether popular runtimes can read a file. Downloading a multi-gigabyte file just to find out takes too long.
My role
Author of the project: problem definition, a public site in six languages, open source code (Apache-2.0), the pilot “Model Release Audit” service. The format is parsed by a t27 parser from my Trinity Memory repository; the t27 compiler was written by Dmitrii Vasilev.
Outcome
The free check runs in the browser: it reads only the start of the file (up to 256 MiB), uploads nothing and shows a verdict for llama.cpp, PrismML, bitnet.cpp and mortar.cpp. A copy runs on Hugging Face Spaces. The manual release audit is a pilot, free until 4 November 2026.

Open research codeResearch

Trinity Memory

My project

The problem
Ternary model weights are stored in different formats. We need to know exactly whether different programs read them the same way.
My role
Author of the repository and releases; I run the checks and findings. The work builds on the t27 language and compiler by Dmitrii Vasilev.
Outcome
Releases v0.2.0–v0.5.0 (September 2026) with CI and verified builds. A finding about the official Ternary Bonsai files was confirmed by independent replay and reported to the publisher through a Hugging Face discussion on 27 September 2026. On an ALINX AX7203 board the attention-layer results were checked against a reference calculation (3 October 2026). This is research, not a finished product.

Other projects

Three mobile sites from the studio portfolio: Barba Drinks, Cafeteria Dalla Cruz, Bom Bordo

Websites for venuesWorking

Atalaia Studio

My project

The problem
A café, bar or restaurant needs a website where guests pick dishes and place the order themselves, and the team sees it on a kitchen screen.
My role
Founder of the studio: I build the sites, ordering from the phone, the order panel and QR codes for each venue.
Outcome
The studio page shows eight sites: seven in Florianópolis and one for home-food delivery in Egypt. Menus with photos, ordering from a table or the beach, an order panel. These are working examples; I do not publish data on paid orders.

DiskBloom window: ring map of used disk space and a list of folders by size

macOS appReleased

DiskBloom

My project

The problem
A Mac disk is full, it is unclear with what, and deleting blindly is scary.
My role
Author of the app: idea, native development, tests, release publishing.
Outcome
Shows a map of used space, removes apps together with their leftovers, finds exact duplicates (size, SHA-256, byte-by-byte check) in read-only mode. Only confirmed items go to the Trash. Releases 1.3.0 (7 September 2026) and 1.4.0 (24 September) are published with DMG, ZIP and checksums. The build is not notarized by Apple; a Mac App Store edition is prepared but not published.

Floripa Hiking PRO home screen: a mountain above the ocean, large title and today's conditions summary

Website and chat for hikersWorking

Floripa Hiking PRO

My project

The problem
A hiker on Santa Catarina island needs to quickly decide which trail to take today: weather, wind, sea and route difficulty live in different places.
My role
Author: rebuilt the earlier guide into a new site, with a trail scoring model, a map, a sea section and a server-side chat.
Outcome
The site shows live weather, a 10-day forecast, waves and tides (Open-Meteo), a conditions score for 20 trails with the reasons behind each reduction, a map, checklists and a hikers' chat that rejects links and ads. The scores are informational and do not replace official warnings.

Two KAST Visa Infinite cards on a dark background

On the road

A traveller's card: KAST

KAST is a money app built on stablecoins: virtual accounts, a card, savings and instant transfers (this is how the service describes itself on its official page). On the road it helps in a few ways.

  • One stable balanceYour money sits in stablecoins instead of cash from several countries. You keep one reserve in one place and pay by card wherever it is accepted.
  • A Visa card for everyday spendingCafés, hotels, transport, tickets and online services: anywhere Visa is accepted.
  • Fast transfersInstant transfers make it easy to split a rental or pay back a travel companion without hunting for an ATM or waiting for bank days.
  • A backup on the roadIf your main card fails or gets blocked, a separate card and an account in the app are a useful fallback.

How I can help

Five offers. Each one comes from work you can look at.

  1. A venue website with ordering from the phone

    Situation

    You run a café, bar or shop, and orders are taken by hand in messengers.

    What you get

    A multilingual site with a menu and photos, ordering from a table, the beach or for delivery, an order panel and printable QR codes. First you try a working demo on your own phone, then you decide.

    BasisAtalaia Studio

  2. Model release check (GGUF)

    Situation

    You publish local model files and want to know whether popular runtimes will read them.

    What you get

    A manual review of agreed public files: header findings with JSON evidence and one recheck after your fixes. Answer quality, security and speed are not assessed. The pilot is free until 4 November 2026.

    BasisTrinity Check

  3. AI tools and workflow automation

    Situation

    You already work with AI assistants, but every session starts from zero and there is no way to verify the output.

    What you get

    Shared memory for agents modelled on my Brain: rules, handoff notes between sessions, checking results against sources. Tailoring it to your process starts with analysing the task.

    BasisBrain in the catalogue

  4. A small app or utility

    Situation

    You need a compact program for one specific job, without a heavyweight platform.

    What you get

    A native macOS app with a clear interface, automated checks and a build you can download and verify by checksum.

    BasisDiskBloom

  5. Explainer videos about complex technology

    Situation

    Your technology is hard to explain to clients or partners in plain words.

    What you get

    A series of short videos in several languages: script, voice and editing with AI tools, claims checked against primary sources.

Results and about me

I am a co-founder of Trinity, a project on ternary computing for AI. In our team of two I run the business side: capital, partnerships, market entry. Engineering leadership and the t27 compiler are the work of Dmitrii Vasilev.

Alongside that I build my own products: a Mac app, websites for venues and model-checking tools. I live in Florianópolis, Brazil.

How I work

  • A working link firstYou see the product in action before deciding or paying anything.
  • Every claim has a sourceEvery number and status on this page leads to a release, a repository or a live page. What I have not verified, I do not claim; I do not call a prototype a product.
  • AI agents, accountability mineI work with AI agents (Claude Code, Codex) and keep a shared memory of decisions so work is not lost between sessions. I accept results by verification, not by feel.

What is done and verified

  1. DiskBloom 1.3.0 published on GitHub: ready DMG and ZIP builds and a checksum file.

    Source

  2. DiskBloom 1.4.0: English interface and documentation, Mac App Store preparation.
