- Connected a Stripe payment system to collect payments for the app. It has several available subscription plans, and all Stripe details are fully configurable.
- Developed the back-end and front-end sides. Technically, this is a Blazor server-side app.
- Configured the system to make the app work on Azure and made it very easy for the client to upload and update the app on Azure.
- Helped the client start implementing new features in the app that I developed: reviewed his code, tested it, managed task list, etc. Now the client successfully works with the code and implements new features without my assistance.

Employment
Experience
- ASP.NET Core Back-end Developmenthttps://syncmd.com/
This is a US-based medical startup that helps people store and share their medical records. It has a REST API back end and three front ends for web and mobile apps (iOS and Android). All the documents are stored encrypted on the server-side.
- Full-text Search Engine
Role: Senior Software Engineer
This is a robust full-text search engine (online and mobile) for a local search service. A cross-platform search engine for all 2Gis products family.
It uses its own data index to fulfil a high-performance full-text search. It takes into consideration such things as morphology, typos, object popularity, and more. It has a lot to do with algorithms, memory management, and performance. - Omnom Software Engineering
This was for a startup called Omnom. It was a mobile app (and a whole service behind it) which allowed to pay the bill in a restaurant right from your phone without calling a waiter.
The client should just put the phone on the table to make it see the check, click couple buttons in the mobile app, and that's it. The startup wasn't successful, unfortunately, and was finally closed. - ESRI Business Analyst Softwarehttp://www.esri.com/software/businessanalyst
This is ESRI business analyst software that helps the implementation of a location-driven marketing analysis based on different spatial data sets (demographic data, competitor location, customer profiling, and more). It was distributed team with the management located in California, QA specialists in Canada, and developers in Russia.
The software itself is based on ArcGIS technologies (ArcObjects library) and existed as desktop, online, and mobile apps. I worked on the desktop app and the work dealt mainly with a combination of C++ and C# code.
