ABOUT ME
AI Meets Practical Execution.
I combine artificial intelligence, digital creativity and web development to build practical solutions for real-world needs.
PROFESSIONAL SUMMARY
Turning AI capabilities into useful digital outcomes.
I'm an AI-focused digital professional based in Indonesia with hands-on experience in prompt engineering, generative AI, AI-assisted content production, response evaluation, web development and digital marketing.
My work focuses on using AI as a practical problem-solving tool — from designing structured prompts and evaluating AI-generated responses to creating websites, visual content and AI-assisted digital workflows.
I combine AI capabilities with HTML, CSS, JavaScript, design, marketing and rapid prototyping to transform ideas into usable and deployable digital products.
As a native Indonesian speaker, I can also contribute to AI projects involving Indonesian language evaluation, localization, cultural context and response quality assessment.

AI EVALUATION LAB
LLM Response Evaluation Demo.
A practical demonstration of how I compare AI-generated responses using structured criteria such as accuracy, relevance, instruction following, language quality and cultural appropriateness.
Portfolio Demonstration
This case study demonstrates my evaluation methodology and is not presented as a client or employer project.

USER PROMPT
Instruction Evaluation
"Jelaskan apa itu kecerdasan buatan kepada siswa SMP menggunakan Bahasa Indonesia yang sederhana. Gunakan maksimal tiga paragraf dan berikan satu contoh yang dekat dengan kehidupan sehari-hari."
RESPONSE A
Candidate Response
6.8
/10
Kecerdasan buatan atau Artificial Intelligence adalah teknologi yang memungkinkan sistem komputer melakukan berbagai tugas yang biasanya membutuhkan kecerdasan manusia.
Teknologi ini menggunakan algoritma, pemrosesan data dan berbagai metode komputasi untuk menghasilkan keputusan.
Contohnya adalah teknologi AI yang digunakan dalam berbagai aplikasi modern.
Main Issue
Generally correct, but the explanation remains abstract and the example is not sufficiently concrete for the intended audience.
VS
PREFERRED
RESPONSE B
Candidate Response
9.4
/10
Kecerdasan buatan atau AI adalah teknologi yang membuat komputer bisa melakukan beberapa tugas yang biasanya membutuhkan kemampuan manusia, seperti mengenali gambar, memahami pertanyaan, atau memberikan saran.
AI belajar dari banyak data dan pola. Karena itu, AI dapat membantu manusia menyelesaikan pekerjaan tertentu dengan lebih cepat, tetapi hasilnya tetap perlu diperiksa karena AI juga bisa membuat kesalahan.
Contoh yang dekat dengan kehidupan sehari-hari adalah rekomendasi video di aplikasi. Sistem mempelajari jenis video yang sering kita tonton lalu mencoba merekomendasikan video lain yang mungkin kita sukai.
Strength
Clearer language, concrete example, appropriate complexity and stronger adherence to the requested audience and format.
STRUCTURED REVIEW
Evaluation Rubric
Both responses are evaluated using the same criteria to make the comparison systematic and explainable.
| Criterion | Response A | Response B | Evaluation |
|---|---|---|---|
| Accuracy Factual correctness | 8/10 | 9/10 | Both are broadly accurate, while Response B adds an appropriate limitation about possible AI errors. |
| Relevance Addresses user need | 6/10 | 10/10 | Response B is more closely aligned with the needs of a junior-high-school audience. |
| Instruction Following Follows explicit constraints | 8/10 | 10/10 | Both respect the paragraph limit, but Response B better satisfies the requirement for a relatable example. |
| Language Quality Clarity and naturalness | 6/10 | 9/10 | Response A uses more abstract terminology, while Response B is easier for younger readers. |
| Audience Fit Context and accessibility | 6/10 | 9/10 | The everyday recommendation-system example makes Response B more accessible to the requested audience. |
EVALUATOR DECISION
Preferred Response: Response B
Response B is preferred because it follows the user's instructions more precisely, uses simpler and more natural Indonesian, provides a concrete everyday example and communicates the concept at an appropriate level for junior-high-school students.
Overall
9.4
/ 10
EVALUATOR NOTES
Why Response B Wins
01
Better Instruction Following
It directly adapts the explanation to the requested student audience.
02
More Natural Language
Technical concepts are expressed using simpler Indonesian without unnecessary terminology.
03
Concrete Example
Video recommendations provide a familiar scenario that makes the concept easier to understand.
04
Appropriate AI Caveat
It correctly communicates that AI-generated results can still require human verification.
MY EVALUATION FRAMEWORK
How I Review AI Responses.
A good AI response is not simply one that sounds convincing. It should satisfy the user's actual request while remaining accurate, relevant and appropriately written.
01
Intent
Understand what the user actually wants.
02
Instructions
Check whether explicit requirements are followed.
03
Accuracy
Identify unsupported, misleading or incorrect claims.
04
Relevance
Remove unnecessary information and prioritize useful content.
05
Language
Evaluate clarity, tone, grammar and naturalness.
06
Audience Fit
Ensure the response suits the intended user and context.
