AI AGENTS / APPLIED AI / SYSTEMS Based in Indonesia

Connecting AI
to real work.

I'm Timotius, an Informatics undergraduate building practical systems across AI agents, computer vision, and IoT.

Currently developing TimePA, a personal AI assistant.

02 / HOW I WORK

Practical thinking.
Visible progress.

Useful AI starts with understanding the actual problem, then connecting the pieces carefully.

01

Understand the context.

Observe real conditions, clarify requirements, and identify what the available data can support.

02

Build the connections.

Connect models, interfaces, data, and tools into a workflow with a clear purpose.

03

Verify what works.

Test the output, document limitations, and distinguish working features from the next iteration.

03 / ABOUT ME
Portrait of Timotius Ekana Tejo Kesuma

A builder with
a systems mindset.

I'm Timotius Ekana Tejo Kesuma, an Informatics undergraduate at Universitas Kristen Duta Wacana, currently completing my thesis.

My work spans industrial computer vision, connected devices, web development, and personal AI agents. I enjoy turning an ambiguous requirement into smaller, testable parts.
