Work with clear status, dated screenshots and sourced metrics. This page also explains how to verify the evidence yourself.
field record, evidence and compliance risk in one workflow
A field-entry, evidence and rule-checking pilot for Estonian farmers. The 36-rule check and offline use are under pilot validation.
find UX friction before your users do
A public website audit product for collecting observations and priorities. We verify important findings in the browser before implementation.
brand, design system and a new website
A Tallinn car studio that works on one car at a time: a design system from tokens to components, five print pieces and a new static nisbel.ee whose home page loads in 148 KB.
a free groovebox that brings traffic to the shop
An 8-track instrument in the browser for Keep It Underground: the whole beat lives in the link, every beat has a name that comes from its pattern, and sharing is built in so every shared beat leads back to the instrument and the shop.
a domain-neutral assistant kernel that carries two products
A kernel extracted from Mati (@leisson-labs/*) that runs a WhatsApp assistant with text, voice, images and documents; the same kernel will carry the iOS app and Operations OS.
a round-the-clock autonomous engineering swarm
A swarm of Claude Code and Codex CLI agents working on the AgroNutikas repos 24 hours at a time: token telemetry, cost attribution, quota circuit breakers and settings that change without a restart.
from prototype to a live shop
An underground brand that turned its March prototype into an open online shop on 2 October 2026: 22 products with original graphics, made on demand, checkout on Fourthwall, the same terminal aesthetic.
Completed work, prototypes and concepts, each with its own date. These are not live products today.
DJ sync and visualisation that stays phase-locked
Completed, 2025–2026
A sync platform for professional DJ setups: Pro DJ Link, MIDI Clock/MTC, Ableton Link, OSC and Art-Net DMX in one core, a WebGL visualiser and a booth-grade UI in two technologies.
garage operations on a deterministic scheduler kernel
Concept, 2025–2026
Not a calendar but a machine: a 12-stage deterministic tick, delay propagation across the whole board and a 32-fixture conformance suite that proves every scheduling decision by replay.
This is the Leisson Creative work list, covering agricultural compliance and data, UX audit SaaS, assistant products, real-time systems, an online shop, workshop logic and concepts. The list is complete rather than a selected highlight reel — what is a prototype or a concept appears here with the label it actually has.
| Evidence | Where to check it | What it proves |
|---|---|---|
| Live address | open the link in the case study header | the public address responds now; it does not by itself prove production maturity |
| Screenshot date | the caption under the image | the image is fresh, not a year-old marketing view |
| Metric source | a public link next to the metric, or a private source label shown on request | the number comes from the system, not from the copy |
| Status | the status table on the Lab page | the labels are defined rather than applied by feel |
| Machine-readable view | append .md to the address | the same content as plain text, without the marketing layer |
Because a link has to work. When a product's public address is down, or the product is private — for example a WhatsApp product whose Meta app is not public yet — the case study sits here without an external link and the status says so directly. A broken link in a portfolio is worse than a missing one.
Start with the case study closest to your situation and read its decisions section. If the same pattern fits, write and name that case study in your message — then the conversation starts at scope and deadline rather than at an introduction.
