About Me
Yehezkiel David Setiawan is an AI engineer from Bandung, Indonesia, specializing in large language model (LLM) innovation and data engineering. He combines rigorous academic research with practical system development to design, implement, and deploy production-grade machine learning systems. His research and projects concentrate on LLM-driven code intelligence and operational LLM deployment. He develops and evaluates semantic code-similarity systems, empirically measures properties of GenAI-generated code in educational contexts, and designs applied solutions that integrate LLMs into production workflows while addressing detection, governance, and reproducibility.

“Bridging research and real-world systems, because intelligence is only meaningful when it scales.”
"Programming is not about what you know; it's about what you can figure out."
"Information technology and business are becoming inextricably interwoven. I don't think anybody can talk meaningfully about one without the talking about the other."
"Leadership is not about being in charge. It's about taking care of those in your charge."
"Good design is obvious. Great design is transparent."
"The best way to predict the future is to invent it."
"A full-stack developer is someone who is not only comfortable working with backend and frontend technologies but also has a good understanding of the entire web development process."
- Chris Wanstrath
"Being a student is easy. Learning requires actual work."
- William Crawford

S-SPARC
Smart Personal Assistant for Responsible Consumption
Ethical AI learning system designed to mitigate environmental harm and "lazy prompting" through semantic retrieval knowledge reuse and mindful prompting controls.
Behind the Paper: S-SPARC
A single LLM prompt emits 4× more CO₂ than a search query. S-SPARC tackles "lazy prompting" and compute costs through tiered semantic knowledge reuse. In trials with 60 students (2.1M+ tokens), 83.94% of queries were answered purely through knowledge reuse without invoking external generative LLMs.
