HOW WE WORK

From design to source code handover.

01 Design document

We first agree on what to build in a design document (SDD).

02 Working prototype

We build a prototype you can run yourself, based on the design document.

03 Automated tests and cross-checks

We run automated tests on the UI and server, and have another AI look for defects.

04 Delivery and handover

We hand over the source code and operating documents so you can run it yourself.

EDUCATION

We have released 3 courses and 2 books.

All courses and books are in Korean. Courses are available on Inflearn, and 2 more books are planned.

FAQ

Frequently asked questions

What happens after I contact you?

We review your message and get in touch. We define the scope together and agree on it in a design document, then proceed through prototype, testing, and delivery.

How is the cost determined?

We can give a quote once the scope and schedule are set. If you share your budget when you contact us, we will propose what can be done within it.

What formats does training come in?

We offer corporate on-site training for employees, online courses on Inflearn, and workshops. Each program is built around hands-on practice for its audience and level.

What kind of development can you take on?

We build web services, mobile apps (web apps and Android), servers, and workflow automation. The two cases above show the actual scope of what we have built.

What do we receive at the end?

We hand over the source code and operating documents. The goal is for you to be able to run it yourself.

Can you work remotely?

Development and automation run remotely through documents, screen sharing, and messaging. Corporate training takes place on site.
