Workspace Geek is a modern solution for managing shared office spaces based on Angular and Web API.

This was an already ongoing project when I joined and my role was to assist the team in developing their latest features. I tapped into the team process and development within a week and started delivering new functionality from the first sprint.

I had the role of a full-stack developer and worked on the front end (Angular, RxJS, and Nx) as well as the .NET Web API back end and the database stored procedures.

A brand new ERP solution for the forest industry based on Angular and Web API. The customers were relying on an old ERP system based on stored procedures, which had 20 years of history an needed to be redesigned.

I had a team lead and solution architect role. I communicated the requirements with the customers and developed the core UI components and the back-end for them. I was also responsible for the migration of the stored procedures to C# code and also the creation of a new background task system based on Hangfire.

A solution for sending critical messages in hospital environments.

I was responsible for designing and implementing a new feature, which would allow instant push notification messages to be sent to on-premise Zebra Android devices. This new feature managed to deliver thousands of messages through RabbitMQ, even when the hospitals and devices had no internet connection.

I also had to integrate a new way of tracking message routing performance. The information was logged to Elasticsearch and allowed support staff to easily track a message that was delayed and provide feedback for critical support tickets.

I led a team of developers in the creation of a WPF application, which communicated with specialized high-end thermal imaging cameras. The cameras streamed gigabytes of data per minute and I had to ensure that all this data is stored without any losses.

As a technical lead In this project, I had to train the developers in WPF as they had no desktop experience before. Additionally, I was responsible for designing a plugin architecture for the application, which would allow third-party hardware manufacturers to develop plugins for the measurement units that they produce.

A web-based Angular application for providing reports with medical data to third parties.

My role was a full-stack developer and technical lead. I was responsible for communicating the workflows with the customers and designing the system in compliance with HIPAA regulations regarding medical data.

Data protection specialists are now using the portal to provide data to organizations, which conduct medical research.

A portal for collecting health information like blood pressure and blood sugar from users with health insurance and displaying a metrics dashboard.

My role on this project was full-stack developer. I worked on the feature, which collected the health information from users and displayed it to them in the form of interactive graphs with jQuery UI. I had to collaborate with the customer's team and send the collected information to their services for analysis.

A React application for evaluating and auditing hospitals and medical facilities.

I worked on this project as a full-stack developer. I was responsible for functionality, which collected audit feedback from trained staff and generated reports with the medical facility's evaluation score.

A Dynamics Business Central extension, which imports window manufacturing information from the leading window design software Orgadata LogiKal into the ERP system.

I was responsible for reverse-engineering the Orgadata LogiKal database structure of the exported information in order to extract the right information. I also rained the customer's team into using the new import tool and oversaw the import process to ensure that all requirements are fulfilled.

I developed a signing service for a rental business. The service would collect the signature of a customer on a signature pad and send it to Microsoft Dynamics NAV.

I managed to overcome the challenge of placing the graphical signature on a PDF contract and storing it in the ERP system.

An Angular web portal, which allows management staff to schedule work for mechanics to work on-site.

I was a full-stack developer on this project and had to integrate it with Microsoft Dynamics NAV. The app would get directions between jobs on different sites and draw them on a map. It would then arrange the task for each mechanic, including travel times, so his manager would be able to slot his work for the next day properly. The tasks were then sent to a mobile app for the mechanic to see.

I did a project in my spare time that would stitch aerial images of forests taken from a drone.

This was done using Azure's storage to allow having a message queue for jobs, tables to store logs and file storage for processing.

A local instance of a worker in Docker would pull the next job from the queue and run a library that would stitch all images from a folder on one big image. It would then get uploaded back to the storage.

This is a personal open-source WPF desktop project that I maintain. It is an app, which features remote server connectivity over various protocols. I work on this in my spare time and I use it daily in my work with remote machines.

I participated with a team of university students in the 2013 Microsoft Imagine Cup. We managed to win the national final and participate in the international event hosted in St. Petersburg.

I worked on a mobile application, which connected to a car's board computer over a diagnostics port with Bluetooth and displayed suggestions to the driver for fuel economy improvement.
