Humanoids.
Web. Apps.

I train humanoid robots and build the software that makes them, and your business, actually work.

First, the robot wakes up.

Data collection, retargeting and training. I build the chain that gives a humanoid its first movements.

Simulation & RL in Isaac Lab with domain randomization
GR00T and LeRobot fine-tuned on your own data
Measured, not guessed — policies scored with repeatable probes against the robot's own model

Trained in simulation. Running in reality.

And all the software around it.

Web, apps, CRM, integrations and AI. One person, the whole chain.

More than code. One person who covers the whole chain, from the robot's policy to the app your customers use.

Four things I do really well.

I step in where the expertise is missing and deliver what has to work in production.

Three stacked ceramic slabs, the top one edged in coral

Web development

Fast, considered websites and web apps

Booking, CRM and customer portals that replace spreadsheets

React, TypeScript, Node and Postgres

Two ceramic smartphones, the upright one with a coral face

App development

iOS and Android from one codebase with React Native and Expo

Camera, sensors and ARKit when the app needs to see and measure

Published on the App Store, Google Play, and as a signed desktop app for macOS and Windows

Digital solutions

Automation and AI integration in existing systems

ANPR, IoT and camera pipelines connected to the business

Integrations with Fortnox and other APIs

From demonstration to a policy in production.

This is what a humanoid training pipeline looks like when I build it. Every step is something I have set up, debugged and run for real.

  1. 01

    Data collection

    Motion capture with ARKit, teleoperation and simulated episodes. Known measurements and calibrated rigs.

  2. 02

    Datasets

    Episodes normalised to LeRobot v3 and versioned on Hugging Face, with every file validated.

  3. 03

    Retargeting

    Human motion mapped to the robot's kinematics. Joint order and reach verified against the URDF.

  4. 04

    Simulation & RL

    Locomotion and manipulation environments in Isaac Lab. Reinforcement learning with domain randomization.

  5. 05

    Foundation models

    Fine-tuning NVIDIA GR00T N1.7 and LeRobot policies (ACT, diffusion, SmolVLA, pi0) on your own data, with checksummed, versioned artefacts.

  6. 06

    Deployment

    A staged rollout pipeline: simulation validation, shadow and supervised stages, approval gates and rollback, with telemetry in Rerun.

Robotics · Platform · App

Humanoid training stack

A platform for humanoid data collection and control: an iOS mocap app on ARKit, retargeting to a 31-DoF humanoid, LeRobot datasets, simulation and live visualisation. All the way from human motion to robot.

Portrait of Alexander Wiman

Alexander Wiman. Engineer, builder, consultant.

I have built digital products for more than ten years: SaaS platforms, mobile apps and systems for the public sector. In recent years my focus has been humanoid robots and how to teach them to work, from data collection to a policy in production.

What I offer is simple: one person who covers the whole chain, writes code that runs in production, and tells you what is realistic before the project starts.

Engagements. Hourly, retainer or fixed price per project.

Roles. Robotics engineer, tech lead, full-stack, app developer, advisor.

Location. Stockholm and remote. Travel across Europe.

Got a robot, an idea or a system that has to get done?

Tell me briefly about the project. I usually reply within 24 hours.
