What we do

Take the whole project or just one slice of it — design only, build only, whatever you need. Tell us where you want to start.

Application software development

Internal business systems your team uses every day, and customer-facing web services. Often the work starts by moving a spreadsheet-and-paper process onto a screen.

What's included

  • Business management systems (intake, assignment, settlement, permissions)
  • Customer-facing web services and membership systems
  • Admin back-office, statistics and reporting screens
  • Legacy system renewal and data migration

Mobile app & game development

Mobile games in Unity and apps built on web technology — including store submission and post-launch updates.

What's included

  • Unity-based Android and iOS games
  • TWA and hybrid apps wrapping an existing web service
  • Store submission, review handling and build pipelines
  • Post-launch updates and metrics-driven improvement

E-commerce & commerce platforms

Not just listing products and taking orders — making the order, settlement and delivery flow actually fit together.

What's included

  • Own-brand storefronts with product and order management
  • Marketplace and brokerage commerce with split settlement
  • Payment, shipping and third-party API integration
  • Operating structures compliant with Korean e-commerce regulation

Technical consulting & maintenance

We also take on systems that are already running — reading code nobody handed over, and getting it back to a state you can change safely.

What's included

  • Taking over and maintaining existing systems
  • Incident response, performance tuning and security review
  • Advice on technology stack and architecture choices
  • Server and deployment setup (Docker, CI)

How a project runs

Every project follows the same steps, however small. Each one is signed off before the next begins.

  1. STEP 01

    Consultation & requirements

    We listen to what you need and how you work today. If it isn't defined yet, we define it together here.

  2. STEP 02

    Design & estimate

    We map the screens and the data model, lock the scope, and give you a schedule and a cost.

  3. STEP 03

    Development & check-ins

    We build feature by feature and show you working screens as we go, so course corrections happen early.

  4. STEP 04

    Acceptance & release

    We test with real data and deploy to production, with handover documentation and account setup included.

  5. STEP 05

    Operation & maintenance

    After release we stay on for incident response, new features and performance work.

Have something you want built?

A rough idea is enough to begin with. We can work out the shape of it together.
