Sensimity & the AI-lert Box
The whole chain, sensor to insight. The AI-lert Box fuses radar, camera, air quality and a beacon mesh on one Raspberry Pi board — and warns people before the accident happens.
Apps, websites, webshops and electronics — led by a product owner who prompts, checks and decides. AI does the typing; every call on what gets built, and when it’s right, stays human.
AI writes production code. It can’t decide what should exist, why, or what “right” looks like. That’s the product owner’s job — and at 2code4 it never gets delegated.
Most software fails at the concept, not the code. Every project starts with the real need — who uses it, where, and what has to change.
Flows, screens, priorities and what to leave out — prototyped with AI under close direction, and clicked through before any production code exists.
The product owner writes the brief; Claude Code writes the code — apps, sites, webshops, firmware and dashboards, from one seat.
Vibecoding without steering is just vibes. Every output is reviewed — architecture, edge cases, fit with the concept. AI proposes; the product owner decides what ships.
A product goes live early and keeps evolving. Each iteration is a short, agile sprint through the same loop — concept, prompt, check, decide — driven by what real users do.
Every product below was built this way — from sensor boards and firmware to App Store apps and live webshops.

The whole chain, sensor to insight. The AI-lert Box fuses radar, camera, air quality and a beacon mesh on one Raspberry Pi board — and warns people before the accident happens.

The most comprehensive pisco catalogue available — bodegas publish their bottles; drinkers search, scan labels, rate and keep a personal cellar. The newest and largest build in the portfolio.

Time tracking apps and the website to go with them — being built right now, the same way.
| Aspect | A traditional team | 2code4 |
|---|---|---|
| Who decides | Spread across roles, meetings and tickets | The product owner. AI proposes, a human decides |
| Who holds the idea | Passed from brief to analyst to designer to developer | One person, from first conversation to launch |
| First working version | After specs, estimates and a few sprints | Clickable while the concept is still being discussed |
| Changing your mind | A change request and a new estimate | A conversation and a new build |
| Range | A specialist per layer | Apps, web, firmware and dashboards from one seat |
| What you pay for | Hours of typing | Decisions, and the judgement to check them |
AI does the typing. I do the thinking: I prompt, I check, I decide. That’s what building software looks like now.
Bring the idea — an app, a site, a shop, a device. Working out what it should be is where we start.
