Meet — Rangga Egha

Profile

From machining engineering to software, I see technology as a tool for organizing real work.

My name is Rangga Egha Permana, an Informatics Engineering student at Universitas Buana Perjuangan Karawang with a vocational background in Machining Engineering. I learn from two worlds: technical precision in the field and building systems through software.

I work on web applications, internal applications, dashboards, data management, cashier systems, organization/SME websites, and technical needs related to hardware, networks, and simple automation. For me, an interesting project is not only one that looks good, but one that answers real problems: messy data, manual processes, hard-to-read reports, or workflows that take too long.

AIinMy workflow

AI-assisted Development

Following AI as part of my working system.

I have a strong interest in AI development, regularly follow updates around tools, models, and workflows, and am used to applying AI in software work.

For me, AI is not a replacement for technical ability. It is a powerful tool and already part of my daily workflow for speeding up research, understanding errors, planning features, comparing solutions, writing documentation, refactoring code, and exploring new approaches.

I believe AI will become an important part of the future of software development. That is why I try to use it productively and responsibly: AI output still needs to be read, tested, adjusted to project context, and reviewed manually.

  • ChatGPT
  • Codex
  • Cursor
  • Claude
  • Gemini
  • Kimi

04

Documentation

Creating technical notes, changelogs, and feature explanations.

05

Prompting

Writing clear instructions so AI output is more relevant to project needs.

06

Workflow Automation

Exploring ways to speed up repetitive work without losing manual control.

01 / 06
