ABOUT

Finance background.
Technology focus.

I am a financial technology builder and researcher pursuing an M.S. in Financial Technology at the University of Central Florida, with a B.Sc. (Hons) in Applied Accounting from Oxford Brookes University. My background gives me a practical view of both sides of financial innovation: how financial records, controls, budgets and business operations work, and how data, machine learning and software can improve them.

My interests span quantitative finance, accounting analytics, digital assets, blockchain security and applied machine learning. I enjoy taking a financial problem from concept to implementation—designing the data pipeline, selecting and evaluating models, and turning the result into a usable web application or research benchmark.

Alongside technical work, I have entrepreneurial operating experience as Co-Founder of Charles Beatina PBC, a meat-processing startup. Managing purchasing, budgeting, supplier decisions, cash flow and day-to-day operations strengthened my interest in building technology around real business and financial problems.

SELECTED WORK

Projects

01 · QUANTITATIVE FINANCE · LIVE

Hedge Master

An applied quantitative-finance platform for exploring portfolio downside exposure and hedging decisions. Hedge Master brings market-data analysis and risk calculations into a simple web workflow and produces automated summary reports for communicating the analysis.

02 · MACHINE LEARNING · LIVE

PMRC

A probabilistic market analytics application that uses LightGBM and engineered distribution, technical and market-context features to classify equity return environments into Large Down, Small Down, Neutral, Small Up and Large Up regimes. The interface emphasizes probabilities so users can see model uncertainty rather than only a single label.

03 · ACCOUNTING AI · LIVE

AuditShield AI

An applied accounting-AI platform built around transaction-ledger risk analysis. AuditShield AI explores automated identification of normal activity, accounting errors and potentially fraudulent journal-entry patterns, connecting accounting-domain knowledge with supervised and relational machine-learning approaches.

04 · FINANCIAL ML

Corporate Distress Predictor

A multimodal financial-risk research project that combines structured corporate financial information with narrative disclosure text to estimate forward corporate distress risk. The project explores how quantitative fundamentals and language-derived information can complement one another in predictive modeling.

05 · BLOCKCHAIN · DEEP LEARNING

Bitcoin Chainlet Forecasting

Research-oriented deep learning using Bitcoin on-chain transaction-network chainlets as structured signals for price forecasting. The project explores multilayer perceptron and graph-based architectures to connect blockchain transaction structure with subsequent market behavior.

06 · OPEN DATA · KAGGLE

Universal ERP Accounting Risk Dataset

An open-access synthetic ERP accounting benchmark designed for machine-learning experiments on financial risk. The dataset supports research on normal transactions, accounting errors, fraud patterns, transaction gaps, approvals, user behavior and verification trails.

ENTREPRENEURSHIP

Building beyond the model.

CO-FOUNDER · 2022–2025

Charles Beatina PBC

Co-founded and operated a meat-processing startup, combining hands-on business operations with financial management. My responsibilities included operational budgeting, supplier evaluation, purchasing, purchase orders, commercial disbursements, budget-variance reviews and monitoring cash flow and margins.

This experience shaped how I approach FinTech: technology should solve operational problems, improve financial visibility and support better decisions—not exist only as a model or prototype.
