Case Studies

// Secure Payment Processor

The goal is to develop secure payment processing system

Created modular application interacting  with payments sources and destinations and provided UI for management and operational purposes . Embedded Defense in Depth strategy including  Network Isolation, Sensitive information encryption, logging and alerting, RBAC for functions and financial limits, RSA key chained payment signing/verification, interaction with PKI, integration with KYC/AML provider, adaptive ML based antifraud scoring, smart payment routing, state monitoring and reconciliation.

// ML research expertise

The goal is a third party research results validation

The machine learning model was reviewed using following steps.
Data feed tested: quality, availability and delays in raw data inflow; feature generation algorithms; data imputation analysis; outliers check; post-processing review.
Features’ relevance for a given ML problem was checked using feature importance calculation algorithms and services.
Training set adequacy checked: the balance of classes, data leakage.
Checked cross-validation algorithm and model quality assessment method.
Executed overfitting tests.
Evaluated model results delivery efficiency in the production environment.

// Investments recommendation system

The goal is to provide research and create investments recommendation system

We did research to create working machine learning models. Developed systems for backtesting and simulations. Built and launched a pipeline for collecting data from source systems, transforming and cleaning data, generating features, post-processing features, machine learning, delivering results, executing recommendations and results visualisation.
