AI

AI-Energy-Forecasting-System

An industrial machine learning pipeline for multi-horizon energy consumption forecasting. The system generates 7-day hourly energy demand forecasts with under 3% Mean Absolute Percentage Error (MAPE) using lag variables, rolling window statistics, and ensemble regression models including Random Forest and XGBoost. It models industrial tariff structures and load scheduling to help utility operators mitigate peak energy costs and prevent over-generation waste.

AI

AI-Powered Cybersecurity Threat Detection

An intelligent intrusion detection system combining supervised classification and unsupervised anomaly detection to identify network vulnerabilities in real time. Powered by Random Forest classification and synthetic network traffic simulation, the solution processes flow telemetry, flags attack signatures such as DDoS and port scans, and presents live triage metrics through an interactive Flask web dashboard modeled after modern Security Operations Center (SOC) workflows.

AI

AI-Powered Medical Image Analysis

A clinical-grade deep learning pipeline designed to detect pneumonia from chest X-ray radiography. The architecture leverages transfer learning with MobileNetV2 for lightweight, high-accuracy binary classification, coupled with Grad-CAM (Gradient-weighted Class Activation Mapping) visual heatmaps to ensure interpretability. The system provides automated triaging, preprocessing radiography scans, calculating confidence scores, and localizing pathological lung infiltrates to support clinical diagnostics.

Frequently Asked Technical Questions

Should our architecture use REST, GraphQL, or gRPC?

We recommend REST with OpenAPI for public third-party APIs, GraphQL for dynamic client-side mobile/web dashboards requiring customized payloads, and gRPC for high-throughput internal microservice-to-microservice communication.

How do you secure APIs against unauthorized access and scraping?

We employ cryptographically signed JWTs, IP-based rate limiting via Redis token bucket algorithms, CORS domain whitelisting, input schema validation, and SQL/NoSQL sanitization middleware.
