Naman Narendra Choudhary

Fingineur — Finance × Engineering × Entrepreneurship

👤 Who Am I?

A builder obsessed with systems — market systems, engineering systems, and business systems.
I combine Quant Finance + Engineering + Decision Science to design tools that help traders, analysts, and operators think clearly and execute efficiently.

💡 What I’m Really Good At

  • Quant Thinking — breaking complexity into models, regimes, probabilities
  • Market Logic — volatility understanding, liquidity intuition, risk sizing
  • Analytical Engineering — building systems that actually work under constraints
  • Excel Mastery — advanced modelling, automation, data cleaning, dashboards
  • Python Workflow Building — fast prototyping, data pipelines, financial logic
  • Problem Solving Under Pressure — hackathons, trading, system design
  • End-to-End Execution — idea → model → code → dashboard → documentation

These are core strengths, not tools.

🛠 My Toolkit

Finance & Quant: HMM, Time Series, Volatility Modelling, Regime Detection, Portfolio Math
Data: Python, Excel (Advanced), Pandas, NumPy, Matplotlib
Engineering: ESP32, MATLAB, IoT Prototyping, Sensor Logic
Trading Tools: Position sizing, risk engines, scenario modelling
Soft Skills: Decision-making, structuring complexity, fast learning

🚀 Projects That Represent Me

  • Market Regime Engine — HMM + liquidity logic for macro regime detection
  • Digital Payments Compliance Engine — anomaly detection for UPI/RTGS
  • Inflation Forecasting System — CPI/WPI forecasting with SARIMA
  • MRAS — multi-regime alpha system (TF + MR + Panic Reversal)
  • Advanced Excel Models — valuation sheets, scenario planners, calculators
  • Hardware Builds — ESP32 gaming controller, Peltier fridge prototype

These showcase: logic, structure, system thinking, and execution.

🎯 What I’m Aiming For

To become the perfect hybrid:
Quant mindset → Engineering execution → Entrepreneurial decision-making.
