I'm a Senior Software Engineer with 15 years of experience using various technologies, mainly delivering to the web back-end architecture with C#, .NET, running it in AWS cloud and using various DBs (SQL Server, Oracle, MySQL, SQLite, MongoDB, etc.). Despite my focus on back-end, I’m capable of touching Front End as well using JavaScript/TypeScript. In the past I had experience writing production software using C/C++.
Throughout my career I've been always careful in following the code standards and pursuing to establish those in the team, ensuring in code quality using TDD practices, writing unit and integration tests, using static code analysis tools and root cause analysis processes.
In the last 8 years, I played key roles in engineering and management decisions while working on the highly loaded award winning online banking system Access Digital that is used by 400 credit unions around the USA with more than 4M users. As a tech leader I participated in the design and development of almost every aspect of our online banking system: from payments and accounts management to messaging, customizations, and configurations, operating with banking cores and integrations with third-party systems with code quality and information & data security in mind. I played a key part in implementation of ~100 API integrations with third-party vendors using various SSO protocols like SAML, oAuth, OpenID, and many custom ones, worked with various cryptographic libraries and protocols.
In the past, I had experience in building logistics software for GIS & navigation, and online booking system in travel. Find portfolio of the projects I've been working on my web site https://optiklab.github.io/employment.html
