About
Working at the intersection of research and implementation.
Anything that deals with Machine Learning and algorithms has always piqued my interest. Recently I've been analyzing polymarkets and developing trading strategies for cryptocurrency markets. I have a strong passion for research and am always looking for opportunities to learn and grow in the field of financial engineering and machine learning.
My research centers on reinforcement learning for sequential decision-making, optimal trade execution, and market microstructure, applying rigorous statistical and quantitative methods to real trading problems.

Experience
Research, leadership, and competition results
IMC Trading Competition: 15th in the US (Top 0.12%)
Apr 2025- Placed 15th in the US out of 12,600 teams in IMC's Prosperity 3 trading competition.
- Optimized trade execution under latency constraints by engineering fair value estimators and implementing dynamic bid shading.
- Designed signal-driven market-making strategies by analyzing mean-reversion patterns and synthetic mispricing.
Undergraduate Commodities Competition (Houston, TX)
Oct 2025- Built a quantitative pricing engine in Python (NumPy, Pandas, SciPy) to back a multi-leg trade thesis (Short Jan '26 Waha Basis), calibrating a modified Ornstein-Uhlenbeck process to model structural temperature mean-reversion (κ = 0.2905) and local price drivers (R² = 0.40).
- Programmed a time-varying seasonal volatility matrix using an integrated cubic B-spline smoothing model, running 10,000 Monte Carlo path simulations to price winter Heating Degree Day (HDD) exotic call options for weather-risk hedging.
Quantitative Researcher, Dataism Lab for Quantitative Finance
Oct 2024 – Present- Researching optimal order execution by analyzing the market microstructure of Bitcoin trade data to develop and implement advanced trading strategies.
- Constructed benchmark execution algorithms in Python, including VWAP and TWAP, to analyze the market impact and transaction costs of trading Bitcoin.
- Engineered a Double Deep Q-Learning (DDQL) architecture in PyTorch, extended into a Mixture of Experts that routes limit order book episodes across K expert networks via an unsupervised K-Means router.
- Designed a repeated-training evaluation protocol (100 seed-paired runs per configuration, with parameter-matched dense controls) to separate real architectural effects from training-seed noise.
- Built the verification suite that audited the pipeline end to end, validating the execution model numerically against an independent re-implementation, reconciling campaigns across devices, and overturning several of the study's own published explanations.
Market Research Analyst, FinTech Club
Oct 2024 – May 2025- Led a project under Dr. Daniel Rodriguez replicating Evans & Archer (1968) via Python simulation, analyzing portfolio diversification and risk reduction.
- Utilized Pandas, NumPy, and SciPy on historical stock data to model risk vs. portfolio size, quantifying diversification benefits.
- Demonstrated and presented findings confirming that most unsystematic risk is mitigated with 10-20 assets.
Summer Researcher, Virginia Tech MAOP Program
May 2025 – Jul 2025- Conducted a mixed-methods research study on pedagogical patterns in introductory Computer Science to identify opportunities for improving student retention and engagement.
- Developed a quantitative framework with eight distinct categories through an open coding process to classify the thematic focus of programming examples.
- Utilized computational text analysis software (LIWC-22) and large language models to quantitatively assess the linguistic and contextual nature of course materials.
- Synthesized findings to reveal a high prevalence of abstract mathematical examples, providing data-driven recommendations for incorporating more culturally relevant and real-world applications in curricula.
Research Mentor, REACH Lab
Jan 2025 – Jun 2025- Guided undergraduate researchers within the Reimagining Equity and Accessibility in Computing for Humanity (REACH) Lab at Virginia Tech.
- Mentored peers on literature review best practices, database search strategies, and synthesizing findings for equitable computing research.
Undergraduate Research Assistant, REACH Lab
Mar 2024 – Jun 2025- Conducted an extensive literature review under the leadership of Dr. Ihudiya Finda Williams on Rural Computer Science Education.
- Synthesized over 80 articles to support a $500,000 National Science Foundation grant proposal.
- Trained six research assistants on database search methodologies, prompt design for scholarly queries, and rigorous literature review techniques.

Mixture-of-Experts for Cryptocurrency Order Execution: Training Stability, Tail Risk, and Failure Modes
Ali Habibnia, Alexander Ardaiz, Varun Budati
A diagnostic study of whether mixture-of-experts (MoE) architectures actually help reinforcement-learning agents liquidate a large position in cryptocurrency markets. We retrain every configuration 100 independent times on Binance BTC/USDT limit order book replay: vanilla Double Deep Q-Learning, MoE at K in {2, 4, 8}, and dense networks parameter-matched to each expert budget. That way the comparison is between distributions of training outcomes rather than between single lucky runs. No configuration improves mean execution cost, and the benefits the architecture appears to have turn out to be separable. Across-seed training stability and within-policy tail risk are distinct axes, and they move in opposite directions. Most of the work went into building controls that could overturn our own result, and into reporting the ones that did.
