The article presents an analysis of the network stability of modern banking systems from the point of view of graph theory. The use of graph models makes it possible to effectively describe complex network structures, identify bottlenecks, and predict system behavior during failures or attacks. Algorithms based on graph theory, such as Dijkstra's Algorithm, have been proposed to ensure minimal transaction processing time and improve system reliability. A comparative analysis of various optimization methods through modeling on abstract graphs and real banking network data was carried out. As a result of the study, solutions were proposed to protect the banking system, as well as improve its connectivity and fault tolerance.

The article is devoted to the developed code designer for the Scilab environment, which is intended to automate the process of creating software modules. The program allows you to generate code for Scilab through an intuitive interface, providing users with tools for working with variables, loops, graphs, system analysis and user-defined functions. The constructor allows you to write programs for Scilab without knowledge of a programming language.

Keywords: Scilab, code designer, programming automation, code generation, visual programming

Modern software development approaches requires perfect stable infrastructure and processes linked with that. Infrastructure has to be highly available, reliable and provide fast and comfortable tools for deployment, support, upgrade product. This article describes software development approach which is allow to use modern tools and methodologies to improve product quality, speed up its delivery and significantly increase stability. As a result it was considered to use GitLab, Jenkins, Git and Kubernetes technologies as basis of infrastructure and DevOps, CI/CD and IaaC as methodologies and how to introduce it in the company.
