Projects
Side projects I design, deploy, and operate end to end on AWS, from data pipelines and research tooling to production hosting and monitoring.
A data product that connects source-labeled prices, completed-sale evidence, and PSA population data for each exact card, printing, and grade, alongside portfolios, watchlists, market news, and collector discussion.
A trading system where no strategy trades until it passes a standard evidence bar. A single Strategy Lab replays every strategy, market, and direction under the same costs and fill rules, then applies statistical verdict gates before anything reaches the broker.
Smaller, self-contained projects in quantitative finance and infrastructure delivery. Each repo has tests, CI, and screenshots from real runs.
FX option pricing and portfolio VaR, served, monitored and deployable. A FastAPI risk service that prices FX options with Garman-Kohlhagen and measures portfolio beta, Sharpe, and Monte Carlo VaR and expected shortfall, with Prometheus metrics, a Grafana dashboard, tested Terraform and CI.
FX options risk engine: Greeks, pair-level risk, spot/vol scenario heatmaps. Prices a book of FX options with Garman-Kohlhagen, nets Greeks by currency pair, and fully reprices the book across a grid of spot and vol shocks.
Estimate CAPM beta, alpha and expected returns from daily prices. Regresses each stock's excess returns on a benchmark to report beta, annualized alpha, R², standard errors and CAPM expected return, with rolling beta and security market line charts.
Simulated price ranges, target odds and tail risk for any ticker. Estimates drift and volatility from log returns and simulates thousands of geometric Brownian motion paths, reporting percentile bands, target probabilities, VaR and expected shortfall.
Stock charts, indicators and risk stats from the terminal, online or offline. Turns daily prices into candlestick charts with moving averages, Bollinger bands and volume, plus multi-ticker comparisons and per-ticker return, volatility and drawdown.
Market data CLI for EODHD prices, quotes and return stats. Searches instruments, pulls end-of-day prices and delayed quotes, and summarizes returns, volatility and drawdown, with clean CSV and JSON output for scripting.
Terraform changes go through PRs, get reviewed plans, and apply only from trunk. Every pull request gets static checks, security scanning and a saved plan posted for review; only trunk can apply that exact plan, behind an approval gate.
An approval-gated pipeline that proves the deployed commit is serving. A declarative Jenkinsfile takes a Python service through tests, image build, container smoke test and parallel Kubernetes, Terraform and Ansible checks, then deploys only the approved plan.
Hardened, tested Terraform module for EC2 with Session Manager access. A reusable module that launches an Amazon Linux 2023 Graviton instance with IMDSv2, encrypted gp3 and Session Manager instead of SSH, with validation that stops unsafe settings at plan time.
