Industrial AI Operating Loop

01

Sense

Production data, machine signals, transactions, manuals, and operational context become usable evidence.

02

Model

Forecasting, retrieval, simulation, SQL, and optimization turn messy processes into decision-ready structure.

03

Decide

Dashboards, assistants, APIs, and interfaces help planners, engineers, and users act with confidence.

04

Improve

Results feed back into reliability, capacity, service quality, waste reduction, and continuous improvement.

Offline CNC RAG Assistant

Built a local retrieval-augmented generation assistant for CNC machine operation and maintenance documentation, using a Haas Mill NGC manual as a realistic manufacturing corpus.

Result: 839 indexed manual chunks, hybrid retrieval, cited local answers, Streamlit UI, and 100% page hit rate@5 on the evaluation set.

Demand forecasting project preview
Python, XGBoost, Pandas, Scikit-learn, Streamlit, Docker

Demand Forecasting

Built an end-to-end forecasting pipeline for the Rossmann Store Sales dataset, covering 1,115 stores and 1M+ rows with leakage-conscious feature engineering and recursive future forecasting.

Result: 9.23% MAPE, 0.914 R², and 55% RMSE reduction versus the best naive baseline.

Remote Real-Time Industrial Production Monitoring & Control

Built a real-time industrial monitoring platform with live telemetry, OEE analytics, alarms, audit logging, and secure remote machine control using FastAPI, MQTT, and Docker.

Result: Real-time MQTT telemetry ingestion, OEE and downtime analytics, role-based machine control, audit logging, and a containerized FastAPI–React stack.

Maintenance mode predictor preview
Python, Scikit-learn, Pandas, Statistics

Maintenance Mode Prediction

Built a decision tree classifier to predict industrial machine operational states using sensor and maintenance data, with tuned hyperparameters and interpretable feature importance.

Result: 96% accuracy with key predictors including Sensor5, Age, and Sensor2.

Fedrigoni industrial AI challenge preview
Python, Pandas, NumPy, XGBoost, Matplotlib, Seaborn

Industrial AI Challenge - Fedrigoni

Analyzed and modeled the slitting process at Fedrigoni's Arco plant to support predictive production planning and improve manufacturing decision-making.

Result: forecasted daily slitting output and helped shift planning from reactive to predictive management.

Other Projects

UrbanPulse system preview
Python, Flask, PostgreSQL, Docker, REST, Telegram Bot

UrbanPulse Event & Logistics Planner

Built a process-centric, four-layer service-oriented architecture that helps users discover events and receive weather-aware transport recommendations through a Telegram chatbot.

Result: integrated event, weather, and routing APIs into a containerized event planning workflow.

Retail analytics SQL pipeline preview
PostgreSQL, Python ETL, Advanced SQL, Power BI, Grafana, Docker

Retail Analytics SQL Pipeline

Built a reproducible analytics pipeline that generates synthetic retail data, loads a PostgreSQL star schema, answers business questions with advanced SQL, and publishes executive and operational dashboards.

Result: 10,000 validated transactions, cohort retention, RFM segmentation, KPI analysis, Power BI-style reporting, and a provisioned Grafana dashboard.

HPC cluster preview
C, MPI, OpenMP, PBS, Linux HPC Cluster

Parallel Numerical Integration Using Romberg's Method

Parallelized a high-accuracy numerical method across MPI, OpenMP, and hybrid configurations, then benchmarked scaling behavior across cluster placements.

Result: 31.77x speedup on 32 cores with 99.3% efficiency.
