Hi, I'm Nadhif Faris A.S
AI/ML Engineer & Data Scientist
I build intelligent AI systems by combining machine learning, Large Language Models (LLMs), and data-driven solutions to solve real-world business challenges.

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.

A selection of AI, machine learning, and data science projects.


End-to-End ML Pipeline for 5G Network Anomaly Detection
Built a real-time anomaly detection pipeline that cuts alert volume by 85% while matching a realistic daily review capacity, deployed end-to-end with a live Kafka-to-dashboard serving system.
- • 85% Fewer Alerts vs Naive Rule
- • 2.6x Detection Rate vs Random Baseline
- • 994-Record Verified Replay

Real-Time Fraud & Risk Scoring System
Built a real-time fraud detection and risk scoring system for e-wallet transactions, using LightGBM and a Kafka streaming pipeline to flag fraud with 0.92 PR-AUC on a severely imbalanced dataset.
- • 6.3M Transactions Processed
- • 0.92 PR-AUC
- • $807K Net Value

Uplift-Based Marketing Optimization
Built an uplift model on 64K+ customer email campaign records to identify which customers converts because of an email, cutting send volume by 50%.
- • 4x Random Targeting
- • 50% Email Volume Cut
- • 64K+ Customer Experiment


Automaded X-Ray Threat Detection System
Built a real-time X-ray object detection system using YOLOv12 at ~60+ images per second to identify prohibited items.
- • 82.7% mAP@0.5
- • <16ms Inference Speed
- • 82.8% Precision
Experience & Education
My professional and academic journey in AI and data science.
Data Analyst Intern
Telkomsel, Enterprise Digital Service Delivery
- 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.
