I'm a Top Rated freelancer and Computer Science graduate who works at the intersection of three fields most people treat separately: Statistics & Machine Learning, Bioinformatics, and AI. That combination is exactly what messy, high-dimensional data needs — the statistical rigor to trust the result, the ML to find the pattern, and the biological context to know what it means.
With 3+ years of experience and 24 successful projects (4.98/5 avg. rating), here's what I bring:
📊 Statistics & Machine Learning
Rigorous statistical inference and predictive modeling — hypothesis testing, causal inference (Mendelian Randomization), feature engineering, and ensemble models (XGBoost, LightGBM, Random Forest). I don't just build models that score well; I build models you can defend. Example: a coronary artery disease prediction model reaching 0.956 AUC, with feature ablation to prove what actually drives it.
🧬 Bioinformatics & Omics
End-to-end analysis of complex biological data — scRNA-seq, RNA-seq, WGS/WES — using reproducible pipelines (Nextflow, Snakemake). From raw reads to normalized matrices to differential expression and biomarker discovery. Example: cut analysis time by 40% on large genomic projects through custom automated pipelines.
🤖 AI & Deep Learning
Deep learning frameworks for real diagnostic problems — computer vision, medical image analysis, NLP, and LLM-based tools.
✨ What ties it together
Most freelancers do one of these. I connect them — applying AI and ML to biological and clinical data with statistical discipline, then communicating the findings in publication-ready visuals that both scientists and stakeholders can act on.

I help research teams and technical founders build and validate reliable, testable scientific and quantitative systems — research prototypes, backtesting frameworks, production execution systems, simulation engines, and performance-critical pipelines. I also conduct independent technical review of quantitative models and research frameworks.
Whether you are architecting a new system from the ground up, battling computational bottlenecks, auditing an unpredictable model, or scaling a fragile prototype into production, I can work with you or your team to engineer a robust, high-performance solution.
Background: PhD Physics (NYU, 2018). Quantitative Research at JPMorgan Chase — derivatives pricing on a 1M+ LOC C++ library. Max Planck Institute postdoc — general-relativistic hydrodynamics on 1,000+ core HPC clusters. 13 peer-reviewed publications, 1,300+ citations, h-index 12.
WHAT I DELIVER
▸ Quant & Options Engineering
Backtesting frameworks (event-driven or vectorized), walk-forward, leakage checks
Options analytics: Greeks, IV surfaces, Black–Scholes and numerical methods
Research → production pipelines (clean architecture, tests, logging, monitoring)
Execution integrations (e.g., IBKR) and robust order / risk handling
Market data ingestion, cleaning, corporate actions, quality control
ML and statistical time-series models with proper cross-validation (no leakage)
▸ Scientific Computing & Research Tooling
For physics, chemistry, biology, engineering, and any domain where the core problem is mathematical or computational.
Custom numerical solvers (finite volume / finite difference, spectral, particle methods) with stability and convergence analysis
Optimization engines (Bayesian, gradient-based, evolutionary) for experimental design, formulation, and parameter search
Simulation frameworks from prototype to production grade
Scientific data pipelines: ingestion, transformation, quality control, reproducible workflows
Verification and validation: benchmarks, unit / regression tests, convergence studies
Analysis tools, dashboards, and reporting infrastructure for research workflows
Air-gapped and reproducible deployments where IP sensitivity or regulatory context requires it
▸ Quantitative & Mathematical Review (NDA-protected)
Independent technical review of quantitative models, frameworks, and research
Verification of internal consistency, identifiability, hidden assumptions, and mathematical correctness
Assessment of whether the formal structure supports the conclusions drawn from it
Implementation review against specification: numerical stability, edge cases, code-to-spec fidelity
▸ HPC & Performance Engineering
Distributed computing (MPI / OpenMP / CUDA), GPU optimization, memory and I/O tuning
Inference and training infrastructure at scale
Profiling, refactors, and speedups for codebases that need to run reliably under production load
WHY CLIENTS WORK WITH ME
- Trustworthy work — research prototypes turned into tested, reproducible production code; models reviewed against their own claims
- De-risking — failure modes surfaced early (leakage, overfitting, edge cases, scaling bottlenecks)
- Maintainability — clean architecture, docs, handover-ready delivery your team can extend
- Communication — clear milestones, concise updates, realistic timelines, no surprises
- Math ↔ engineering bridge — strong intuition for both theory and implementation
IDEAL PROJECTS
- Quant strategy development, backtesting, and research infrastructure
- Options analytics and derivatives tooling
- Mathematical review of quantitative manuscripts, white papers, or research frameworks
- Independent validation of production models against specification
- Market data pipelines and reproducibility upgrades
- Performance optimization of slow Python / C++ codebases
- Distributed training, GPU optimization, and inference serving for ML workloads
- Custom scientific or industrial simulation and numerical software
- Internal R&D tooling for research labs and technical teams
