I build AI systems, computer vision, and data pipelines for companies, including on-premise setups where internal data never leaves your own servers.
Data Scientist and AI Engineer who takes a problem all the way from raw data to a system that runs in production. I build end-to-end ML pipelines, retrieval-augmented (RAG) chatbots over internal company documents, and computer vision systems wired to sensors and controllers on the factory floor. Comfortable across ETL and streaming pipelines (Kafka, Snowflake, Airflow), model training and deployment, and the dashboards that make the results usable by people who are not data people. 1st Place Winner of the Snowflake Hackathon Partner 2025. Currently taking on freelance projects in data science, AI engineering, and IOT.
Available for freelance projects, remote or on-site in Jakarta
Chatbots that read your company documents (RAG), question answering over internal databases, and LLM workflow automation. Can run fully on-premise, so your data never leaves your own servers.
Quality inspection on production lines, defect detection, and object counting, wired to sensors and controllers for automatic rejection plus real-time monitoring.
ETL pipelines, demand and sales forecasting, anomaly detection, churn and risk models, plus dashboards and automated reporting your team can actually read.
Send an email describing what is not working today. No formal brief needed.
We check whether this is worth building at all, and whether I am the right person for it.
You get a written proposal with deliverables, timeline, and cost before anything starts.
Consulting role delivering data science and AI projects for five enterprise clients across different industries.
Built an end-to-end OCR pipeline for SME lending risk assessment with identity verification, financial analysis, and chart extraction. Generated 500 synthetic applicant bundles using StyleGAN2-ADA with realistic document degradation.
Built a conveyor belt quality inspection system using YOLOv8s trained on 1,500 self-annotated images (7 classes) with Arduino-based automatic rejection, plus a Streamlit dashboard for inspection report visualization.
Built production-grade Local RAG System with n8n: dual-mode data handling (SQL + vector search), AI routing, semantic caching. Full-stack: Docker, web UI, 5 workflows, PostgreSQL, Qdrant, Elasticsearch, MinIO. Observability via Grafana/Prometheus/Loki, Ollama LLM inference.
Won 1st place Snowflake Hackathon 2025. Built Real-Time Network Incident Monitoring: Kafka→Snowpipe Streaming→Medallion Architecture. Predictive analytics for outages via Streamlit/Tableau dashboards. Integrated Cortex Analyst/Search, Intelligence chatbot, email automation in unified agent workflow.
Developed two AI chatbots for loan officers (Telegram) and borrowers (WhatsApp) to explore loan data, predict default risk, explain results, and export PDFs. The default risk model reached 74% AUC-ROC, with every prediction explained so officers could act on it rather than just read a score.
Segmented customers in automobile sales to identify high-value clients and visualize trends through interactive dashboards.
Predicted taxi trip durations and identified travel patterns using geospatial analysis and clustering.
Built a fraud detection model to flag suspicious transactions while reducing false alarms.
