Built by engineers who ship.

MelDev AB is an automation and product-engineering shop. We design control systems that run factories, write the software that ties them together, and build the hardware when nothing off-the-shelf will do.

Industrial control

PLC and DCS integration with Siemens, Honeywell, Emerson. Greenfield commissioning, rewrites, retrofits.

Custom electronics

From schematic to assembled PCB. Signal conditioning, peak-and-hold drivers, embedded firmware.

Software, end-to-end

C# / Java backends, iOS & Android apps, OPC / Modbus / Profibus servers, dashboards, databases.

Two decades on the panel.

MelDev is led by Robin Melin — process & control engineer at Honeywell from 2006 to 2018, where he worked as a Lead Engineer on pulp & paper, refinery and quality-control projects across Europe. He left in 2018 to run MelDev AB full-time.

Robin Melin Founder · Lead engineer

Started on the floor as an instrument technician at Selek AB, Hitab AB, and as process engineer at StoraEnso Fors — while finishing ABB Industrial HighSchool on the industrial-process track with extra programming courses A through E and a heavy process-control load.

Joined Honeywell AB in 2006 as Design Engineer in Falun, moved to Mölndal in 2008 as System Engineer working on Experion DCS and Experion MX (formerly DaVinci) QCS, then took the Lead Engineer chair in 2015. National and international rollouts until 2018 — pulp & paper, refining, quality control.

MelDev AB was founded in 2018. Since then: 40+ rollouts in pulp & paper and refining across Europe, plus the bench hardware, automotive electronics, motion VR rigs, and the games and apps that came out of them.

MelDEV Power Boat Racing

Rebuilt from the hull up.
In Unreal Engine 5.

Built in-house and on Steam since 2020, now completely rebuilt in Unreal Engine 5 as version 3.0 for Windows, Mac and iOS. Every boat floats, planes, jumps and slams on water simulated from the hull up. Race on lakes, in harbours and on the open sea, design and paint your own boat, then take it online to Lake Havasu.

Local-first AI, since the day we could.

We’ve been running open-weight language models on local hardware since they entered the public domain — long before “private LLM” was a marketing bullet. No cloud exfiltration. No per-token bills. Your data, your iron.

On-prem inference

Models that live behind your firewall

Llama, Mistral, Qwen, Gemma — quantised, served, and tuned to fit the GPU you already own. Air-gapped deployments included.

Fine-tuning

Tuned to your domain

Maintenance manuals, ladder logic, your CAD library, your incident history. We curate the dataset, run the LoRA, ship the weights.

RAG & pipelines

Retrieval that respects boundaries

Vector stores hosted alongside your data. Document ingestion, chunking, citations — accountable answers with traceable sources.

A short brief is enough to start a conversation. We answer all messages within two business days, usually the same day.
