About us
Engineers who have run the operations they build software for
GuneSys is a small software and engineering company with offices in the United States and Türkiye, serving logistics and e-commerce businesses in four countries.
GuneSys Corp was founded in 2023 in Pennsauken, New Jersey, by engineers who had spent years building and operating e-commerce and warehouse systems. The company started with e-commerce activities and software services and grew into a provider of managed systems for third-party logistics companies.
In 2026 we established a company in Türkiye and opened an engineering office in Ankara. Services are rendered from Türkiye and the US to clients in the United States, Canada, Japan and Türkiye, under written agreements with fixed monthly fees for managed services.
We stay deliberately small. Every client works directly with the engineers responsible for their system, and every system we run is one we would be comfortable running for ourselves.

How we think
Three principles behind every engagement
Write it down
Scope, price, responsibilities and what is out of scope are agreed in writing before work starts. Surprises are a sign of a bad scope, not a bad client.
Run what you build
We operate the systems we deliver. Monitoring, updates and support are part of the service, because software that nobody watches decays.
Keep it boring
Proven technology, small releases, automated tests and plain-language reports. Excitement belongs in your business, not in your infrastructure.
