IT Services

For companies without IT staff, we handle assessment, build and operations as one job.

Our own service

Enter a lot number and it runs from site analysis for land development review through layout of land uses, roads and buildings, a rendering and feasibility review.

In beta operation

SEMOEvery message in the world

Academy teachers write one line in a table after class, SEMO sends it to parents through KakaoTalk notification messages, and the records become a draft monthly report. The service is in Korean.

KakaoTalk notification integration · queue-based bulk sending · recurring billing

Open semotalk.net

Core technology

Refined in our own services and applied as is to client work.

Data encryption

Open it and it still cannot be read

Names and phone numbers are encrypted field by field. The database alone reveals nothing, and values are decrypted only at the moment they are needed.

Field-level AES encryption · decryption at time of use

Data isolation

A customer’s data, for that customer only

Whose data it is gets decided from login credentials alone. An automatic check finds any gap across the whole codebase.

Multi-tenant design · credential-based identification · automatic gap detection

Automated quality verification

Wrong data does not go out

New data is built in full on the side, and if it misses even one check it is not swapped in. After a swap it can be rolled back at once.

Blocking checks · full swap · previous version kept

Public data processing

Scattered data, one structure

Formats that differ by agency are fitted into one. Terms of use are checked source by source, and data we may not use is filtered out.

PostgreSQL · PostGIS · per-source automatic collection

AX (AI transformation)

Rules decide, AI explains

Calculation and decisions are left to rules, and AI writes explanations and drafts. Every number AI writes is checked against the calculated result.

LLM integration · rule engine · figure cross-checks

Source tracing

Every number has a source

The reference date is kept with it and originals are stored as received. What we do not know, we say we do not know.

Original snapshots · source and date per item

IT Total Care

We become the IT team for companies that have no IT staff, from assessment to build to operations.

How it goes

We design and build websites, apps, AI and internal systems.
