Portrait of Dr. Aldo Taranto

About Me

I combine advanced mathematical research with extensive industry experience to develop analytical methods, machine learning systems and data solutions for complex, high-value problems.

With dual doctoral research in mathematics and computer science and 30 years in analytics, quantitative and data roles, I bridge the gap between data analysts, data scientists, data engineers, actuaries and quants.

AI & ML

Model development, optimisation and applied AI.

Mathematical research

Stochastic processes and high-dimensional optimisation.

Data platforms

Enterprise AI & Machine Learning Delivery

Challenge
Identify potential shadow-economy activity and suspected undeclared income across millions of online data sources, enabling the ATO to target limited investigative resources towards the highest-risk entities.
Approach
Led a multidisciplinary team of 6, comprising 3 data scientists and 3 business specialists. Established a secure cloud analytics capability and developed Linux Bash and Python web-crawling, indexing and machine-learning pipelines to analyse 2 million URLs. Built predictive risk models and a decision-optimisation layer to rank entities and prioritise investigative actions.
Outcome
Identified approximately 1,900 entities for investigation, enabling granular risk-based targeting, more effective allocation of enforcement resources and referrals to specialist task forces. Delivered the three-year programme in 2.5 years, completing it six months ahead of schedule, and subsequently applied the remaining contract period to optimise other data science capabilities.

Quantitative Analytics & Algorithmic Strategy

Challenge
Engineer a production-critical, real-time hedging engine for a proprietary trading firm to systematically manage aggregate long and short exposures, control directional risk and automate trading decisions. The system required bespoke MetaTrader 4 (MT4) integration despite limited documentation, with software failures potentially exposing the firm to substantial financial losses.
Approach
Architected and led development of a bespoke C#/.NET trading engine integrating with MT4 APIs. Designed portfolio-level position aggregation, real-time hedging logic, execution management for slippage, requotes and spread widening, circuit breakers, automated and manual position wind-down procedures, and a self-healing recovery framework. Incorporated Managed Account Manager (MAM) functionality for multi-account operations and comprehensive dashboard reporting.
Outcome
Completed and deployed the engine into production on a New York-based cloud VPS, managing a complex multi-account trading architecture. Subsequently refined the software, strengthened its intellectual property protections and developed a more general-purpose white-labelled version for broader commercial distribution.

Predictive Analytics & Commercial Product Innovation

Challenge
Transform a rules-based credit and collections platform into a more sophisticated predictive analytics solution capable of improving debt recovery, prioritising collections activity and delivering measurable commercial value across international markets.
Approach
As Head of Analytics, designed and developed the CWA Engine, integrating predictive machine learning into the existing CollectionWorks (CWX) platform. Engineered an end-to-end modelling framework featuring automated variable binning, variable importance and sensitivity analysis, parallel ensemble modelling, ROC-based model evaluation and population-wide scoring. Developed accessible, menu-driven data ingestion and script-recording capabilities, and led offshore developers in Ho Chi Minh City, including hands-on machine-learning training. Subsequently served as the technical subject-matter expert in international sales engagements across Dubai, Indonesia, Malaysia, Singapore and Australia.
Outcome
Multiple existing customers adopted the new feature, while the engine helped secure new customers and strengthen the product's commercial proposition. Customers reported immediate collection improvements of 20–40%. The engine also contributed to Rubic Financial's acquisition of Admerex, demonstrating the commercial value of translating advanced machine learning into an integrated, market-ready product, which was subsequently acquired by Temenos.
