I architect high-frequency trading dashboards, scalable data pipelines, and distributed ledger systems. Transforming raw institutional market data into actionable, millisecond-precise interfaces.
Impact-driven milestones in fintech and quantitative systems.
A comprehensive view of the tools powering my financial architecture.
Real-world implementations of scalable financial logic.
Architected a real-time, event-driven web dashboard that consumes live market greeks via WebSockets. Computed Black-Scholes valuations on the edge, enabling institutional traders to visualize volatility skews instantly without backend lag.
Designed a highly scalable microservice architecture to ingest, normalize, and cryptographically verify millions of daily transaction logs across disparate clearinghouses. Automated a previously manual 12-hour reconciliation process down to 3 minutes.
Built a core engine in C++ wrapped with a Python interface that allows quantitative researchers to simulate trading strategies over 10 years of tick-level historical data. Deployed parallel processing clusters on AWS to reduce simulation time significantly.
Developed an automated pipeline scraping financial news APIs and Twitter feeds. Utilized custom NLP models (BERT) to assign sentiment scores to equities in real-time, feeding the resulting structured data directly into algorithmic trading models via RESTful APIs.
Led the frontend rewrite of a legacy institutional portfolio manager tool. Transitioned from jQuery to modern Vue.js, implementing D3.js for complex, interactive risk-exposure charts and exposure heatmaps capable of handling 50k+ DOM nodes.
Engineered a highly secure client onboarding portal compliant with strict GDPR and regional financial regulations. Implemented end-to-end document encryption, biometric verification hooks, and robust audit logging for compliance officers.
