My experience


NudgeitOctober 2016 - Present

IT ticket system with a focus on automation. Client-side it was build using angular 2 , later on upgraded incrementally until angular 10.

On the backend side, I was working on a distributed Odata REST API written in .NET Core and hosted on Azure. 

Other services integrated: Azure search, Azure Automation accounts, Logic apps, Sendgrid, Azure machine learning, Azure service bus, Azure SQL, BOT framework 

Another project was to write a .net Core Rest API responsible to test Office 365 endpoints in terms of performance and availability. It was hosted on AWS. 

Other services integrated: DynamoDb, Docker , S3

I was involved in developing a highly secure web application which handles pension benefits. Besides developing functional aspects I was involved in designing and implementing two-factor authentication with different identity providers (Identity Service, Active Directory Federated Services, Kentor). Another security feature that I was working on was related to handling a secure connection between all service layers and handling sensitive data (encryption, decryption and key management).

Firstly, I developed new functionalities for a top product in the capital markets world: Summit FT. Basically Summit FT has a Client - Server architecture which involves on the client side two applications (Windows Forms application and MFC application). On the server side, there is a number of processes written in C++ which provide real time updates, data authorization and data validation for the client side. Those processes are platform independent because between client and server there is an Apache server which handles requests between those entities. My area of expertise was on the Back-Office module where I developed some components which were able to handle external data from different systems and message queues like IBM Websphere. Mostly, external data means transactions exported from different system in XML format or FPML format (Financial product markup language). On the functional side, I worked on various scenarios which involved processing external data in real time in order to measure financial indicators.
Another technical challenge was to improve the way Summit interacts with external data. In this case I`ve built an application where users can visually map XML messages with Summit internal entities.
Secondly, I was involved in developing internal tools to enhance features like continuous integration, code complexity and code review. This was a great opportunity to learn how software with large code base can be maintained in order to be shipped on time. I developed a solution which integrates Bug Management System (JIRA), source control instance
(Accurev) and build management system (Jenkins to manage and have a better view of build requests.

Academy of Economic StudiesDecember 2008 - December 2011

As a research member of Serafimo project ( I was involved in researching mobile technologies in order to implement scenarios related to mobile banking transactions. My contribution consisted in identifying technologies suitable for each scenario (in terms of performance and security) and building a prototype application as an applied result of the research project.

MicrosoftApril 2011 - May 2011

During this period, I have coordinated 5 students in order to develop a Windows Phone 7 Application for discounts offers. It was a great experience with a lot of challenges because it was the first time I was in a lead position. I have to design the architecture of a product which should be able to show specials offers based on your location, create specifications and distribute tasks.
