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.

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.
