About

I’m currently studying Actuarial Science, with a strong interest in quantitative risk, probability, and uncertainty modeling. My academic background includes engineering and applied mathematics, which helped me build a solid foundation in mathematics, statistics, and analytical thinking. I’m particularly interested in how uncertainty can be modeled in financial systems using probability, stochastic processes, and simulation-based methods. Right now, I’m focusing on Python and quantitative finance through small projects in risk modeling, portfolio analysis, and data-driven financial problems. My goal is to develop myself in quantitative risk and financial modeling, where mathematics and uncertainty play a central role in decision making.

Experience

  • EVT & Catastrophic Risk Presentation at University Presentation
    Apr 2026 - Jun 2026 · 3 mos

    Prepared and presented research on Extreme Value Theory (EVT) and catastrophic risk in financial and insurance systems. Focused on modeling rare events and understanding their importance in risk management.

  • Insurance Loss Models (R Project) at University Project
    Mar 2026 - Jun 2026 · 4 mos

    Worked on a loss modeling project using R for insurance applications. Focused on modeling claim frequency and severity and understanding how losses behave in insurance portfolios. Used statistical methods to estimate expected losses and analyze tail risk.

  • Quantitative Risk & Portfolio Analytics at Shahid Beheshti University
    Sep 2025 - Feb 2026 · 6 mos

    Built an automated portfolio analytics and risk reporting system using Python. • Calculated returns, volatility, Sharpe ratio, fear and greed index, news sentimental and maximum drawdown for selected assets. • Generated performance charts and automated email reports.(equity curve) • Implemented basic machine learning models for short-term market direction estimation.

  • Prop Firm Trader at TradersCombat
    Sep 2022 - Feb 2026 · 3 yrs 6 mos

    Traded Forex and US indices, including NAS100 (Nasdaq) and US30 (Dow Jones), under a funded account. Applied technical and fundamental analysis to identify high-probability trading opportunities. Followed strict risk management rules and firm trading objectives. Managed positions while complying with daily and maximum drawdown limits. Maintained disciplined trade execution and performance tracking

  • ERM / Risk Modeling Project at Shahid Beheshti University
    Apr 2025 - Jul 2025 · 4 mos

    Worked on an academic ERM project where a sample company was defined and different financial risks were modeled. Used Monte Carlo simulation and VaR methods (historical, parametric, and simulation-based) to estimate potential losses under different market conditions. Also tested scenarios like oil price shocks and interest rate changes to see their impact on overall risk.
