Senior AI Engineer @ SimplifyAi
Jan 2025 – Present · Full-time · Jakarta
- Designed the retrieval strategy for a legal-document RAG system handling thousands of documents — now reused across multiple client deployments.
- Architected the full agentic-AI platform for a leading Indonesian bank on-site: FastAPI services, LangGraph / Jira / Confluence integrations, guardrails, and CRUD for their engineering, data, and solutions teams.
- Built a dynamic skill framework that lets non-engineers add new agent capabilities with no engineering round-trips.
- Set up monitoring and observability for agent runs in production. Shipped a second bank's full platform in 6 months, in parallel.

Machine Learning Engineer Lead @ Insignia Indonesia
Jun 2025 – Sep 2025 · Full-time · Hybrid, Jakarta
- Built a lead-scoring MLOps pipeline from the ground up — experiment tracking, model versioning, feature management — deployed on-prem so the team owned it.
- Connected GenAI tools (Dify, n8n) into the broader system so automation workflows worked together instead of in silos.
- Shipped an LLM-based OCR system and a RAG pipeline reasoning over medical images (stool analysis) for diagnostic support.
- Owned end-to-end builds for an AI campaign-simulation platform and a "Chat with Your Data" tool: backend, frontend, integrations, CI/CD, database, credentials.
Senior Data Scientist @ PT Delos Maritim Jaya
Jun 2022 – Apr 2025 · Full-time · Hybrid, Jakarta
- Deployed shrimp-disease prediction models (reinforcement learning) that cut PCR testing from ~every 15 days to 4–5 tests per 90-day cycle.
- Ran statistical testing on water-treatment effects, driving an estimated IDR 100B+ in savings by eliminating ineffective chemicals.
- Built computer-vision systems for shrimp-stomach conditions (90% reduction in analyst misinterpretation) and phytoplankton analysis (~30% better than mid-level lab analysts).
- Built AquaSym, a farm ERP (Appsmith + Django), and an automated shrimp-PCR report interpreter cutting lab analysis time ~80%. Built the L1–L4 data pipeline on Redshift + DBT.
- Delivered automated farm-cycle reports and data-analysis dashboards, helping farmers boost profits by 30%.
- Built RAG-LLM tools that let experts query historical farm data for operational decisions, achieving 90% alignment with senior expert recommendations.
- Contributed Go backend services and Next.js frontend across cross-functional teams, expanding full-stack delivery beyond data science.
Full-Stack Developer @ Omdena
Aug 2022 – Nov 2022 · Contract · Remote
- Built the MVP dashboard (user dashboards, Mapbox visualizations, scoring views) in Next.js, improving engagement ~25%.
- Built REST APIs for per-point score calculation (Fastify + Next.js serverless), MongoDB data flow, and secure auth.
R&D Engineer @ Bangun Inovasi Teknologi (BIT House)
Jun 2021 – Apr 2022 · Full-time · Hybrid, Bali
- Built production computer-vision systems: ID-card OCR, crowd-counting for malls, face-recognition attendance, and fish counting / species recognition.
- Developed a full-stack trading-bot app (Vue.js + Django); taught data-analytics bootcamp modules and mentored a national AI competition team.
Machine Learning Engineer @ Omdena
Mar 2021 – Sep 2021 · Contract · Remote
- Built object-detection and classification models to detect fall armyworm in African croplands from satellite imagery.
- Developed an NLP conversational model (RASA) and an abuse-detection model, deployed as a Flask API on Heroku.
