sina-04/README.md

Hi, I'm Sina Rezaei

Industrial Engineering student focused on operations research, analytics, data science, and product engineering. I enjoy turning mathematical models and complex datasets into reproducible tools that people can actually use.

Current focus

Mathematical optimization and facilities planning
Business intelligence and evidence-backed analytics
Simulation, portfolio risk, and decision-support systems
Accessible, bilingual data products

Featured work

Project	What it demonstrates
Zarin Pulse · Live demo	Traceable merchant analytics with Next.js, FastAPI, DuckDB, deterministic metrics, and evidence-grounded AI explanations
GAMS Optimization Portfolio	LP, MILP, NLP, MINLP, cutting-stock, and facility-location modeling with clear licensing boundaries
Portfolio Risk Management	TSE data preparation, risk measures, CDaR, correlation analysis, and Riskfolio optimization
Facilities Planning Algorithms	A tested Python implementation of CRAFT flow-distance optimization
MAL Eternal · Live demo	A bilingual achievement command center with Solar Hijri/Gregorian timelines and analytics
ShirazGo · Live site	A responsive English/Persian metro journey planner with RTL support

Toolbox

Modeling and analytics: Python, GAMS, pandas, NumPy, Jupyter, DuckDB, Riskfolio, operations-research methods
Product engineering: TypeScript, React, Next.js, FastAPI, Vite, Cloudflare Workers/D1, Render
Quality: automated tests, CI, reproducible environments, data contracts, accessibility, and responsive design

Principles

I value explicit assumptions, traceable calculations, honest project status, and documentation that lets another person reproduce the result.
