Industries and Applications Within Banking

Retail Banking

Reliable Backend Infrastructure for Everyday Banking Needs

Our Python developers are experienced in creating backend systems that support high volumes of daily transactions, secure customer account management, and data privacy. They implement automated transaction processing, customer authentication, and API integrations, allowing retail banks to provide a seamless, user-friendly experience while meeting security standards.

Our cases

  • Transaction Monitoring and Microservices Architecture

    This system was designed to monitor banking transactions with a sophisticated architecture of over 100 interacting microservices. It managed exchange rates, data ingestion, FKG mediation, and background processing to improve efficiency and scalability.

    The system used Flask, FastAPI, and Aiohttp for microservices, MySQL and MariaDB for data management, and Azure services like Service Bus, Key Vault, and Container Registry for cloud integration. RabbitMQ was used for message queuing, Open Telemetry for observability, and GraphDB for complex data relationships

  • Python-Powered Crypto Banking Platform

    Our Python developers advanced a cutting-edge banking platform for QIWI, non-bank entities, crypto projects, and media players. The platform featured virtual Visa/Mastercard cards and planned over 70 BINs across various regions. Future enhancements aim to include proprietary crypto-processing and a robust core banking system for European and Southeast Asian markets.

    Initially a monolith, the platform included authentication, user management, card services, and transaction handling. Key microservices, developed with FastAPI and PostgreSQL, communicated via HTTP requests. MassPay managed mass payments through SWIFT and SEPA, using Go, Python, gRPC, and Temporal. The Financial module handled ledger interactions and report generation with Python, gRPC, and Postgres.

  • Automated Legal Fact Extraction for Streamlined Credit Approval

    Our team of Python developers built a high-performance web service for a banking client to accelerate credit approval document reviews. The solution includes two core components: a fact extraction service, which uses NLP models (AllenNLP, Pandas, Numpy) to pull key information and build a fact-tree, and a decision-support service where legal experts apply custom rules, written in a Python-based language, to determine credit eligibility.

    With Kafka for real-time data, SQLAlchemy and Postgres for efficient data management, and Flask for backend operations, we reduced review time from up to five days to under 3 minutes. Post-refactoring with updated model configurations, the service also achieved a 30-40% performance boost, cutting costs and empowering rapid, data-driven legal decisions.
