Data Science / Research

HMM‑Based Market Regime Detection

Hidden Markov Model for financial time-series regime identification

  • Implemented HMM to detect latent market regimes (bull, bear, high-volatility) from financial time-series data.
  • Modeled regime transitions via probabilistic state-transition matrices; estimated parameters using Expectation-Maximization (Baum–Welch algorithm).
  • Analyzed regime-shift probabilities during major events (financial crises, high-inflation periods); compared with change-point detection methods to evaluate structural break identification accuracy.
  • Visualized regime probabilities and state segmentation over time using NumPy, SciPy, and Matplotlib.
Systems / Compiler

Compiler Regression Performance Analyzer

Automated benchmarking system for DMD compiler · Built for D Language Foundation

  • Built automated pipeline to analyze DMD compiler performance across pull requests.
  • Collected metrics: compile time, binary size, and runtime benchmarks.
  • Designed a framework to detect structural performance regressions automatically across CI runs.
Web / Full-Stack

Enterprise Resource Platform

Placement management ERP · 1,500+ users · 85% efficiency improvement

  • React, Node.js, Express, MongoDB; secure JWT auth and email via Nodemailer.
  • Deployed on Vercel with Tailwind CSS and Material-UI responsive UI.
