Featured Work

AI Trading Platform

Alpha Forex AI

End-to-end AI financial forecasting platform processing live market data with automated pipelines for feature engineering, model inference, and signal generation on three years of historical data. XGBoost and LightGBM models over 70+ technical indicators, with real-time risk management, entry levels, stop-loss, take-profit, and confidence scores.

  • Python
  • FastAPI
  • PostgreSQL
  • Redis
  • Docker
  • Next.js
  • XGBoost
  • LightGBM

Research

Adaptive Concept Drift Detection

Adaptive machine learning framework for detecting concept drift in evolving financial time series, enabling predictive models to respond to changing market behaviour. Investigates online meta-learning with reproducible experiments and rolling-window validation under non-stationary conditions.

  • Python
  • Online Meta-Learning
  • Statistical Evaluation
  • Time Series

Document Intelligence & RAG

AI Product Metadata Platform

Intelligent document-processing pipelines extracting structured product information from PDFs and images via OCR and NLP. Semantic search, vector retrieval, and Retrieval-Augmented Generation for discovery across unstructured technical documentation, with REST APIs and interactive dashboards.

  • Python
  • OCR
  • RAG
  • Vector Search
  • REST APIs

Published Research — ResearchGate

Social Influence in Multi-Agent LLM Systems

Empirical study of conformity, belief revision, and reasoning robustness when large language model agents interact under peer influence. Examines how social pressure shapes multi-agent reasoning and where model judgement degrades.

  • LLM Agents
  • Experimental Design
  • Statistical Evaluation
  • Python

Real-Time Computer Vision

Driver Drowsiness Detection

Real-time computer vision system detecting driver fatigue from live video. Eye Aspect Ratio (EAR) and Mouth Aspect Ratio (MAR) algorithms with adaptive fatigue scoring classify alertness and trigger intelligent alerts, with visual analytics for behavioural monitoring.

  • Python
  • OpenCV
  • MediaPipe
  • Real-Time Detection
