I’m also Microsoft certified Azure Solutions Architect as well as DevOps Engineer, both being highest tier of Microsoft's certifications. During my 9 year career I’ve worked as a lead architect and developer on several enterprise applications in mortgage and title insurance industries, each used by 50k+ users. I’ve also worked on designing and creating white-label cloud applications, web applications, APIs, for both enterprises and startups. I specialize in designing and developing highly scalable and resilient applications and I work all across the applications life-cycle: from initial requirement gathering and analysis phase, through the design and development phase, and finally the deployment and maintenance phase My highlight project was a design and implementation of a web and API platform for a Fortune 500 company. The web application, developer in Angular 8, acted as a bridge between an old data store system and a new REST API developed partially in .NET Core and Azure Functions. The application allows users to submit wide variety of orders and tickets to an existing system, while the API provides programmatic way for third-party vendors to integrate with the system. The application and API are capable of supporting over 20.000 orders at a single moment, and over 40.000 users reviewing the dashboard without any latency issues. I was personally in charge of the requirement analysis, architecture design, development and implementation of CI/CD pipelines for the deployments. In the end, MVP version of the application secured millions in funding for the Company which allowed a rapid growth and employment of more than 30 developer and QA resources.. My main area of expertise is application development in .NET/.NET Core and Angular, with either SQL or NoSQL database, and finally infrastructure, configuration and deployment to Microsoft Azure cloud or on-prem Windows servers. Apart from that I've done a lot of work in PowerShell/Batch scripting, Azure infrastructure templating, bots, etc. I’m extremely versatile and familiar with other popular technologies like ReactJS, Vue.js, Docker, Kubernetes.. Finally, as a personal achievement I poses a Microsoft’s MCSD certification (Microsoft Certified Solutions Developer), Microsoft’s Azure Developer Associate certification, several edX certificates for DevOps (IaaC) and, to top it of, I'm a certified Azure Solutions Architect and Azure DevOps Engineer certifications, both being Microsoft's top tier certifications. ————— You can track me down by these keywords: C#, Azure, .NET Framework, .NET Core, ASP.NET MVC/Forms, ASP.NET Core, REST WebAPI, WCF (svc services, asmx, xaml workflows), Windows services, NancyFX, GraphQL, gRPC w/ Protobuf, SignalR, Swagger, SSRS, XSLT, LINQ, Quartz.NET, custom NuGet packages, Node Unit and integration tests, MSTest/xUnit/NUnit, Moq, AutoFixture, SpecFlow Angular 2+, AngularJS, ng CLI, Knockout, HTML, CSS, Sass, JavaScript, TypeScript, Bootstrap, jQuery, DevExpress, WPF, WinForms MS SQL Server, TSQL, Azure Storage, CosmosDb, Entity Framework, ADO.NET with stored procedures/functions, Dapper Microsoft Azure (App Services, Functions, Logic Apps, VMs, ARM/Bicep templates, Service Bus, Redis, CDNs, API Management, AAD...), az CLI, on-prem infrastructure, IIS, Docker, Powershell/Batch scripting TFS, Git, Azure DevOps, CI/CD pipelines (XAML, JSON, YAML), deployments to both cloud and on-prem infrastructure, Infrastructure as Code, Database as Code, SonarQube, VeraCode, ApplicationInsights Enterprise apps (legacy monoliths, n-tier/layer, serverless, microservices), one-offs/PoCs, Agile, Scrum, DevOps, daily code reviews
