Systems that run in code and steel.

I am a Swedish systems architect, robotics engineer and founder operating between Sweden and Shenzhen. I build high-reliability Rust infrastructure, industrial digital twins (Twinton), and physical hardware execution pipelines (ce-net) connecting European engineering with vetted Shenzhen manufacturing floors.

What is built, deployed and running

Digital twin of a factory floor
Twinton Industrial Digital TwinsReal-time 3D operational and physics twins for factories, warehouses, fleets and production lines. twinton.ai
Two CNC cuts side by side at 1x and 8x feed
Pre-Cut CNC VerificationSame G-code simulated at two feed rates before machining. 1x: 10:30, 0 lost steps. 8x: 5:15, scrap caught before metal is cut.

Physics & Operations

Three-dimensional simulation on real-world telemetry

Terrain, weather and factory lines in typed RustReal-world terrain, atmospheric telemetry, and multi-station manufacturing lines simulated in deterministic Rust cells with live WebGL inspection.
Rheo (Acquired by Redpine)Enterprise multi-channel inventory and automated distribution platform. 500,000+ lines of production Rust and React Native with comprehensive automated test coverage. Deployed commercially across a 20-site automotive recycling network in Sweden before the codebase was acquired by AI company Redpine.
TwintonIndustrial digital twin and pre-cut manufacturing simulation platform for factories, warehouses and production lines. Catches CNC scrap, station bottlenecks and tolerance collisions before physical execution. twinton.ai

Executive Summary

Background, governance & how we work

Who is Leif Adamec Rydenfalk: A Swedish systems architect, robotics engineer and founder from Umeå, Sweden, dividing his time between Sweden and Huaqiangbei, Shenzhen. Over the past decade he has architected large-scale Rust backends, zero-copy RPC protocols, industrial digital twins, and physical hardware supply chains.

Why teams hire and partner with us: European and US hardware, robotics and industrial companies use our team in Shenzhen and Sweden to bridge the gap between CAD/software and physical manufacturing. Before a single piece of metal is cut or a PCB batch is run, we verify tolerances in Twinton, audit the Shenzhen suppliers in person, and deliver inspected hardware with a live digital twin.

Trust, IP & commercial governance: Proven through the commercial acquisition of the 500,000-line Rheo codebase by Redpine, multi-site enterprise rollouts in Sweden, and long-term 6-month+ engineering partnerships with hardware sponsors and semiconductor/storage clients in Shenzhen. Client IP is protected under strict bilateral NDAs and Swedish/EU or Hong Kong (HKIAC) commercial law.

Equity & financial foundation: Backed by proceeds from the Redpine code acquisition and active engineering partnerships, Leif holds controlling founder equity across Twinton, the ce-net infrastructure stack, and our Shenzhen robotics and hardware IP.
