Design and develop microservices (Golang, TypeScript, Kubernetes)Resolve security and stability issues such as a weak random number generator, internal data exposure, and cluster resources exhaustion. (JavaScript, Kubernetes)Furnish substantial support to other project teams, encompassing assistance with programming languages such as Golang, C++, C# and JavaScript, package management as well as helping with software design and programming patterns, security protocols, SSL termination, PKI, authorization, RESTful API design and other HTTP and Web-related tasks.Devise a new GKE clusters provisioning including automatic DNS and Ingress set-up as well as Let’s Encrypt certificates auto-installation. (Bash, Go)Key AchievementsRecommended and implemented Simulation Performance Adviser cluster data backup. The solution allows to backup and restore operational data during automated cluster re-provisioning.Pinpointed and repaired a Microsoft container service engine logs rotation policy problem. This problem was leading to disk space exhaustion.Installed the email routing microservice (Go), implemented templates and connected to Sendgrid email API, ported the file upload service from Azure to Google Kubernetes Engine, and implemented a microservice for running scheduled and immediate tasks (Go). Formulated a set of scripts for automatic provisioning Google Kubernetes clusters including SSL termination, DNS and Ingress setup. (Bash, Docker)Updated and replaced the old Rancher oriented logging and monitoring infrastructure with a new one. Used FluentD instead of Logstash and Logspout, proxy metrics from kubelet instead of RanchEye.Built Kubernetes job services for automatic Grafana and Kibana dashboards configuring during cluster reprovisioning. The services greatly reduced the amount of manual intervention. As part of this job created alert configurations for monitoring clusters’ memory, CPU, and disk usage. (JavaScript, Docker)

Determined RESTful API internal standard based on best practices and RFCs.Integrated a significant part of a highly versatile continuous delivery system based on the Docker builder pattern (Gradle).Pioneered cluster logging support (ELK stack) as well as utilized cluster monitoring support to monitor critical resources as well as operational costs. (Prometheus, Grafana)Defined and extracted a library containing logging, error handling, health check and others cross cutting concern implementations (Go).Initiated several microservices responsible for user accounts handling, workflow orchestration, file uploading, mail generation and distribution, Docker container and images cleanup and other functionality. (Go)

Created and implemented a visual filters panel. The panel improved Petrel’s 3D canvas usability by streamlining access to otherwise hidden functions. (WPF, C#)Optimized mathematical algorithms for calculating hydraulic fractures, streamlines and simulation events (C++).Elevated application's usability by analyzing and implementing technology replacements and upgrades (C#, C++/CLI).Assessed and improved performance of critical parts of Petrel reservoir engineering components including OpenGL renderers.Scrutinized architectural proposals, public API changes, new public API introductions and provided highly appreciated input.Realized various proof of concepts, such as a split remote 3D rendering based on WebGL. (JavaScript, WCF, REST), and a Web service and a UI for reservoir simulation results and events. (ASP.NET, REST API, Swagger, Angular)

Finished the User Experience project and industrialized the related code. The project received an industry award as a highlight of a remarkable productivity change with Petrel 2014.Evaluated Petrel code base for the large models performance bottlenecks and 64-bit memory model support. (AQtime, C++, C++/CLI)Initialized and introduced code contracts to the user experience libraries to improve code static analysis and reliability. (C#)Integrated automatic mocks with the user experience testing libraries to improve test coverage and modularization. (C#)Implemented managed extensibility framework (MEF) in order to improve modularization and extensibility of the UX related API and libraries.Assessed windows presentation foundation (WPF) components from different vendors for the new Petrel UI.

Made major contributions to the ambitious User Experience project for improving Petrel usability and UX.Revamped Petrel’s look-and-feel by introducing ribbons, contextual toolboxes, window tools to Petrel. (C#)Designed the first version of the Petrel configuration designer (C#).Executed Petrel core refactoring, restricting access to the fundamental Petrel components. (C++)Installed a new API that significantly improved Petrel extensibility and was used by plugin writers for implementing more than 1200 commands and UI tools. (C#)Served as a mentor guiding an intern sthrough an ambitious project. The project provided camera positioning algorithms and touch gesture recognition for the 3D touch support in Petrel. (C++, C++/CLI). The result of this work was presented on NDC conference in Oslo and featured in local newspapers.

Introduced Petrel project logger and project backup (C++/C++/CLI).Created and implemented Docking Manager API (C#). Initiated Petrel core isolation (C++) achieving greater modularizing and testability for fundamental Petrel components.Identified and enabled the tabbed MDI windows support in the Petrel user interface. (C#, C++/CLI)Built and implemented Petrel favorites pane (C#).Installed UI controls library containing completely custom WinForms for the managed part (.NET based) of Petrel. (GDI API, C++/CLI) Utilized a performance profiling tool (AQTime) and profiled critical parts of the fractures modeling (C++).Merged a new .NET managed infrastructure for the Petrel wells module (C#).Designed a Web-portal for the Windows error reporting (WER) service for capturing Petrel crash dumps. (ASP .NET)Executed Petrel code analysis and fixed shortcomings in the core parts of the application. (C++, C++CLI/C#)Built prototype of a new generation of the Petrel infrastructure, which remains an inspiration source for Petrel core team. (C#)
