Work Experience

  • January 2025 - July 2025
    Courts Singapore, Indonesia

    Data Scientist

    • Built and deployed ML models for customer segmentation, demand forecasting, and risk scoring using Scikit-learn, TensorFlow, and PyTorch.
    • Designed a scalable anomaly detection for 9M+ daily e-commerce records, detecting abnormal sales spikes, scraping errors, and metadata inconsistencies.
    • Implemented self-cleaning logic and data quality rules (e.g., for price/title jumps, missing values) to ensure clean, reliable datasets for downstream analysis.
    • Developed hybrid rule-based and ML-based logic to validate sales spikes, tag campaign-driven behavior, and detect anomalies in e-commerce trends.
    • Automated P&L reporting and financial ETL processes, improving SLA adherence and saving 3+ hours of manual work daily.
    • Delivered real-time insights and visualizations using Python (Pandas, Seaborn) and enhanced stakeholder dashboards.
    • Built NLP solutions for chatbots, text classification, and smart document search to support automation and efficiency.

  • January 2024 - December 2024
    Mandala Multifinance, Indonesia

    Data Analyst

    • Designed and maintained data marts and analytical datasets in PostgreSQL and Oracle to support internal reporting, dashboards, and business decision-making.
    • Created and optimized complex SQL queries to extract insights, update legacy logic, and support evolving business requirements.
    • Automated manual data processes using Python scripts, including scheduled email reports and database migration tasks, reducing recurring workload for operations teams.
    • Collaborated with software engineers to build and integrate MFIN, an internal dashboard system, by delivering robust and accurate SQL back-end logic.
    • Automated database migration with Python scripts, reducing migration time by 90% (from 1 hour to 5 minutes).
    • Designed and implemented interactive Power BI dashboards, eliminating 10 hours of manual reporting per week.
    • Developed stored procedures and materialized views to support ad hoc data analysis requests from product and finance teams, improving report turnaround time.
    • Partnered with cross-functional stakeholders to define business rules and translate reporting requirements into reusable SQL and data models.

  • July 2022 - December 2023
    Accenture, Indonesia

    Data Engineering Analyst

    • Built and maintained scalable Airflow DAG templates supporting 5,000+ dynamic data quality checks across key domains (e.g., revenue, churn), covering six dimensions: completeness, timeliness, consistency, accuracy, uniqueness, and validity.
    • Led and supported an L1 team (3–6 members), optimizing data quality dimensions (completeness, timeliness, consistency, accuracy, uniqueness, and validity), reducing project timelines by 2 months.
    • Collaborated with client’s DQM lead and data governance teams to implement validated configurations, ensuring KPIs exceeded 90%+.
    • Designed and optimized SQL queries (Oracle, Hive), with final outputs validated in PostgreSQL via Kafka streams.
    • Managed and troubleshot distributed infrastructure, including Hadoop memory cleanup, Kubernetes pod restarts, and DAG performance tuning.
    • Developed SOPs and automation tools to accelerate L1 task execution and configuration rollout, completing the implementation phase 1 months ahead of schedule. 
    • Maintained platform stability by addressing incidents via Jira and collaborating with developers on system-level issues.
