MelPump
NetShow's own platform that monitors and automatically controls heat pumps from several manufacturers, for homeowners and installers. It runs each one around electricity prices, sunshine and the weather, so households pay less, up to hundreds of pounds a year in the UK.
NetShow runs all of it: the device firmware, the cloud platform, the apps and customer support.melpump.com
Besides its own products, NetShow engineers inside platforms built by others. On both engagements below, its founder Artur Rychcik did the work himself, as part of the client's team.
GatherUp helps businesses collect customer feedback and manage their online reviews. NetShow's work ranges from the most complex features, including HIPAA-related ones, to architecture across the platform.
INFRAPORT connects acoustic leak sensors on water pipe networks to one platform that shows leaks on live maps. NetShow joined while the platform of around 30 services was already running and engineered services and data pipelines that process its sensor data.
NetShow Systems is a Polish company owned and run by Artur Rychcik, systems architect and creator of MelPump. He designs the systems and writes the code himself; on larger projects he has employed and worked with other engineers.
I worked with Artur at GatherUp for 4 years when I was CEO. He is a high performing lead engineer and often headed up the development of our most complex features for our platform with over 25,000 users.
Artur was just such an engineer who delivered time and again sophisticated, easy to use features that worked. He was instrumental to our success and ultimate sale.

Work starts from the outcome a client needs: lower running costs, fewer losses, a platform ready for its next stage. The design, the build and the years of looking after it in production follow from that.
Projects are not priced from a list: two nearly identical systems can differ widely in cost because of one important detail. So every quote starts with a careful look at your scope and its risks.
Conversation
The outcome you need, the system you have today and the constraints around it.
Scope and proposal
Scope, risks, stages and cost reviewed and returned as a written proposal. Estimates are free of charge.
First working version
An early version in real use, then development in stages you can see working.
Maintenance for years
Monitoring, fixes and further development, with response times for critical incidents set in the contract.
A system to build, a system to take over and maintain, or operations to automate. Artur Rychcik replies personally.
