I worked on improving performance, scalability and resiliency of the system which supports smart charging of the electric vehicles (EV): * 5x decrease of a latency of processing telemetry coming from EVs (implemented a smart cache pattern using Orleans - a framework for distributed computing); * implemented scalable EV telemetry processing backend which automatically scales into multiple server instances; * several times fixed performance bottlenecks and memory leaks; * migrated ASP.NET (and library projects) from .net framework 4.6 to .net core (now called simply .net); * Dockerized services and led a process of moving entire infrastructure to Kubernetes to make our services cross-platform (in terms of cloud providers); * Developed unified integration mechanisms for processing the EV telemetry from different vendors using Websockets, RabbitMQ REST and Kafka. * Have been making demos for product managers and team. Hosted weekly internal team knowledge sharing activities.

I successfully deployed to production two projects inside Microsoft. * I developed the system to visualize and build data classification rules. Based on these rules then graphs were constructed for data analysis; * I led a team which built a system for screening process automation (with requirements to handle 5000 RPS). I developed an employee notification system based on email delivery. Also I integrated CI/CD processes. Technologies: asp.net core (2.0), Azure WebJobs, Azure SQL Server, Angular 5, Azure Functions, Service Fabric, Service Bus, VSTS.

I led development team on building a supply chain tracking system based on Ethereum blockchain technology. We have reached a working prototype stage. Technologies: Ethereum blockchain, asp.net core (1.1), Angular 5, Postgres, Orleans.net, TeamCity.

* Developed core platform modules which have been adopted by team across the company to implement business applications.◦ Developed a library for distributed task processing

* I developed tools and libraries for cryptographically signing/verifying different documents; * I set up a certification authority software (Vipnet); * I organized an in-office telephony based on Asterisk; Techologies: ASP.Net MVC 3, JQuery, C++ (Win API), Asterisk
