Information Retrieval
Cross-Lingual Retrieval and Reranking (TP3)
Compared lexical, hybrid, and dense retrieval with multilingual rerankers over 3.19 million documents, placing 4th on the class Kaggle leaderboard and studying ranking-quality versus runtime trade-offs.
Reinforcement LearningModeling Infectious Disease Outbreak for Optimal Government Intervention
Modeled pandemic response as an MDP in a stochastic four-city SEIRD Gymnasium environment, then compared PPO, A2C, and a restricted DQN baseline under health, economic, and budget constraints.
Deep Learning / FinanceIDX Intraday Stock Return Prediction using TCN
Developed a causal multivariate forecasting model to predict 15-minute future log returns for 100 target stocks on the Indonesia Stock Exchange, using high-dimensional market features, Temporal Convolutional Networks, baseline comparisons, and calibration for near-zero market movement.
Information RetrievalA Preliminary Study of Grouping Strategies for ListT5 Reranking
Extended the inference procedure of ListT5, a listwise reranker based on Fusion-in-Decoder T5, by studying grouping strategies, tournament-style reranking, caching behavior, and BEIR benchmark trade-offs without retraining the underlying model.
Information RetrievalMini Search Engine
Built a complete mini search engine using Python, NumPy, SciPy, and FAISS, covering indexing, compression, TF-IDF, BM25 variants, WAND optimization, LSI retrieval, approximate nearest-neighbor search, and query evaluation.
Speech AIIdentification of Authentic and Forged Segments in Partially Spoofed Speech
Studied detection and localization of synthetic segments in speech using Wav2Vec2-XLSR features and temporal attention, reporting both utterance-level and frame-level error rates.

Computer Science Student at Universitas Indonesia
Studying computer science while building projects across AI research, software systems, data, product work, and team-based engineering.
Experiences
- Bachelor of Computer Science
- Research projects in information retrieval, reinforcement learning, deep learning, computer vision, and speech processing
- Full-stack, mobile, database, game, and functional programming course projects
AI Product Engineering at Klaussa.com
Worked with end-to-end ownership in a startup, understanding legal-product workflows and delivering features across AI, backend, data, and frontend systems.
Researcher Intern at LEXIN
Researching how LLMs can translate Indonesian judicial reasoning into readable symbolic representations while preserving the meaning of the source, at the Center for Legal Informatics, UI.
Experiences
- Python prototype for preparing court passages, generating structured outputs, and reconstructing Indonesian text from the representation
- Repeatable prompting and bounded-correction experiments with retained run artifacts
- Source, representation, and reconstruction comparison to inspect missing or unsupported meaning; semantic evaluation remains ongoing
Directed exploration
Connecting AI research, product work, digitalization projects, and business learning into a clearer long-term AGI trajectory.
Current Works
- Undergraduate thesis on faithful translation of judicial reasoning at LEXIN
- Self-organizing knowledge engine (pal) with CLI and MCP interfaces
