About Me

A quick look at my background and where I focus my work.

AI/ML Engineer and Data Scientist with hands-on experience spanning production ML systems, causal inference, and LLM-powered applications, backed by a Microsoft Azure AI Engineer Associate credential and enterprise data exposure through a Telkomsel internship. Skilled across the full delivery lifecycle, from data quality diagnosis and model design to RAG pipelines, agentic workflows, and cloud deployment. Comfortable translating messy, real-world data and complex AI systems into validated, stakeholder-ready solutions that both technical and non-technical audiences can act on.

Artificial Intelligence Engineering

Designing intelligent applications powered by machine learning, Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), AI agents, and modern AI frameworks.

Data Science & Machine Learning

Developing predictive models, performing data analysis, feature engineering, model evaluation, and transforming data into actionable insights.

Data Analytics & Visualization

Creating interactive dashboards, analyzing business performance, and communicating insights through effective data visualization and business intelligence tools.

Experience & Education

My professional and academic journey in AI and data science.

Data Analyst Intern

Telkomsel, Enterprise Digital Service Delivery

Jul 2025 — Aug 2025
Jakarta, Indonesia
  • Cut manual data-integration effort by ~95% (from 1–2 hours to under 5 minutes per cycle) by designing and implementing a unified consolidation workflow for ~4,800 sales pipeline records sourced from Area Account Manager (AAM) and Corporate Account Manager (CAM) systems.
  • Strengthened data reliability for enterprise decision-making by auditing and correcting data quality issues such as mismatched IDs, incorrect date formats, missing fields, and SLA formula errors, then presenting validated, analysis-ready datasets to 6 senior stakeholders.
  • Enabled real-time visibility into revenue and delivery performance by building 3 interactive Looker Studio dashboards tracking revenue pipeline, project completion, and project trend metrics for enterprise digital solution reporting.
