Outsourcing software development,
Entrust your project to a development company that truly understands your work.

From equipment integration and ERP customization to digitizing manual tasks and rebuilding legacy systems, we have been designing and developing operational software for public institutions·manufacturers·research institutions since 2000, across desktop·web·mobile·embedded platforms.

Starting from “There is no software that fits the way we work” We begin.

We identify and resolve the root causes of real-world operational problems that off-the-shelf software cannot solve.

Digitizing manual workflows

Your workflows rely on Excel and paper

When several people circulate their own Excel files, versions get mixed up and totals have to be compiled manually every time. We digitize the process with screens designed around your actual workflow.

Equipment integration

Unable to extract data from equipment·measuring instruments

We connect directly to manufacturer-specific interfaces such as serial·TCP·PLC·proprietary SDKs, bringing data collection·monitoring·reporting together in one system.

ERP customization

The ERP we adopted does not fit our processes

Instead of replacing the entire system, we develop only the additional modules you need or build a separate administration system that connects to your existing ERP.

Legacy system redevelopment

A program built 10 years ago, with no one available to maintain it

We analyze systems whose original developer is no longer in business or whose source code is disorganized, then take over maintenance or rebuild them while preserving the data.

App development

You need a mobile app for use in the field

We design for sites with unreliable connectivity, including offline operation·synchronization. We support both native Android/iOS apps and hybrid apps.

Idea validation

You want to check feasibility first

Before building the full system, we first implement the core features on a small scale to assess technical feasibility and the likely cost.

Frequently asked questions

Common questions before contacting us

Is there a charge for a quote consultation?
Consultations and estimates are free of charge. Documenting the requirements is part of the contracted scope, and charges apply only after the contract is signed.
What should I prepare before contacting you?
You do not need a formal project brief. Just tell us three things: ① how you currently do the work, ② what is causing difficulties, and ③ your approximate budget·preferred timeline. We will work through the rest together during the consultation. If you have screenshots of existing screens or Excel templates, please attach them.
Who owns the source code?
The details are agreed upon in the contract. As a rule, we hand over all source code to the client. We also provide documentation so your in-house developers can take over maintenance.
Do you also take over systems built by other companies?
Yes. If the source code is available, we can review it and take over maintenance. If the code is missing or can no longer be maintained, we recommend rebuilding the system while preserving your data. We begin by assessing the current situation.
Can you also deploy in an isolated network with no internet access?
Yes. We have extensive project experience with public institutions·research institutions and are familiar with on-premises installation, deployment in segregated network environments, and security review procedures.
Can you sign an NDA (non-disclosure agreement)?
Yes. If you request it during the consultation, we will sign an NDA before discussing the details.
What happens if a problem arises after delivery?
We address defects free of charge during the defect correction period specified in the contract. After that, you can choose an annual maintenance contract or support on a case-by-case basis.
