Eugene Blokhin

Freelance software developer

I design the architecture for new features, participate in backlog grooming, perform code-reviews, address support issues from our customers, participate in the recruitment process

• Tech stack: ASP.NET Core, SQL Server, MongoDb, Docker, Azure Dev Ops
• Led and designed architecture during a consultancy project where we developed an ETL pipeline to migrate data of tens of thousands of patients from a proprietary database to Firely Server for one of our clients. The project has been successfully completed in a timely manner meeting all the requirements
• My teammates especially positively recognize my approach to onboarding of new colleagues that helps them to get up to speed faster compared to previous hires

Freelance software developer

Led the development (designing the architecture, building, and maintaining) of controlling software for a hardware 3D scanner. The generated 3D models were used in a AR/VR marketplace.

• Tech stack: ASP.NET Core (Blazor), C++, Linux, Raspberry Pi, Arduino
• Re-wrote the original solution and improved code maintainability and reliability
• The high-level part is an ASP.NET Core Blazor-based web application running on Raspberry Pi (Linux)
• The low-level part is written in C++ and runs on ATMega328P micro-controllers

Senior Software Developer

• Tech stack: C#/.NET, Azure Storage/Functions/App Services/Service Bus/ARM templates
• Designed and created a backup solution for our event-sourcing system log stored in Azure Tables (> 2.5 TB of data)

Software Developer

• Tech stack: C#/.NET, NServiceBus, Azure Storage/App Services/ServiceFabric/Service Bus...
• Set up CI/CD pipeline with TeamCity and Octopus Deploy. It made the deployment simpler, more reliable, and less error-prone. It also allowed for urgent rollbacks
• Wrote custom serialization/deserialization implementation for Azure Table Storage which worked 20x faster than the default Microsoft implementation
• Pioneered rewriting our initially synchronous order flow to use asynchronous messaging architecture. It opened up a way for extending functionality and dramatically increased reliability. It still facilitates the processing of ~200k orders per day
• Created a system to calculate and generate invoices for our clients. Commissioning of the system was smooth and hundreds of clients received their first invoices without any issues
• Modernized our integration RESTful API testing suite to make more future-proof

Software Engineer

Built and maintained software powering out photo-products production facilities in The Netherlands and India.

• Tech stack: C#/.NET, ASP.NET, SQL Server, RabbitMQ
• Modernized a windows service to deliver more than 3.5 TB of user's photos daily from the cloud to our print factory. It allowed decommissioning several obsolete services, therefore, improved reliability and maintainability
• Implemented a set of SQL static analysis tools to help us keep our database schema under control
• Gathered requirements and analyzed workflows in one of the production cells. Then, developed a monitoring system to help distributing workforce more evenly to achieve the maximum throughput possible

Software Developer

• Tech stack: C#/.NET, ASP.NET WebApi, SQL Server, SoapUI
• Took the ownership in performance testing and optimizations for our new RESTful service
• Wrote my master's thesis based on this project

Junior Software Developer

• Tech stack: C#/.NET, Unity3D, DirectDraw
• Shared my work experience on a stage in front of approximately 200 people audience of a game dev conference
