Senior .NET Developer

1) The gas supply optimizer (MVP1-MVP5) What I did 1. Versioning of data (0+12, 1+11, ... 12+0) 2. Versioned data copier (a new version is created on the existed base) 3. Decision tool (calculates many gas supply variants) 4. The formula's calculator (user can change calculation settings) 5. Migration from .NET Core 2.2 to .NET Core 3.1 6. Calculator's optimization About formula's calculator - User can write: Table(filter by name).Filter1(data)...FilterN(data).Property (+ other formula's data: functions, other tables, etc.) for example, Consumer("consumer 17").Month(-1).Price - data will be taken from consumer's price for the previous month - Lazy data loading, data loads only when is used - Data cache (scoped by version and API request) 2) Turn based browser game (Demonstration) 1. Used SignalR to notifications and game state changing 2. Short project, has developed for 7 days

TIK RPE LLC | Jan 2015 - Jan 2019

.NET Developer

1) The vibrodiagnostics platform (TIK-RVM) What I did 1. Developed distributed system of modules (data server, math rules server, etc.) 2. SQL and storage system optimizations (~70GB data per day) 3. UI for desktop application. This app is used to configure monitoring objects 2) The visualization system for TIK-RVM platform (custom SCADA) What I did 1. The core 2. The script system (for interactive UI) 3. UI 4. Base primitives for making SCADA projects 5. Lots of things to ease making projects, such as batch renaming and intellisense in script editor Advantages 1. Project speed loading improvement (~40 sec against ~10 minutes) - lazy loading UI (project's pages load after first display) 2. Runtime cycle improvement. - data updates into two threads (the first - what the user sees, the second - all the rest) For example, a user sees only one aggregate at the moment of time, its data updates as fast as possible. Whereas, in existing SCADA system all data is updated linearly.
