{freelancer}Team oriented
With over 5 years of experience in team leading, I am a team player who can work with people from different backgrounds and cultures. I value hard work and dedication and I am always ready to help my team members.
Algorithms enthusiast
Since the beginning of my career I have been interested in algorithms and data structures. I have participated in many algorithmic competitions and I have a lot of experience in this field. My Computer Science faculty and thesis was also focused on algorithms.
Backend focused
My main area of focus in software development is backend. I have a lot of experience in developing backend services and APIs. I have worked with many technologies and I am always eager to learn new ones. I'm not afraid of going deep into the code and solving complex problems. I'm familiar with multiple databases and search engines like SQL, MarkLogic, ElasticSearch and Redis.
Problem: not enough visibility of builds in ADOPS pipelines
Solution: I've created a custom web application that presents builds in TeamCity like way. Data is fetched directly from Azure Devops API and cached in Redis. Application groups builds based on branches and allows to rebuild failed runs. It also allows to see the changes in the build and to see the build log in real time. Tool is connected to MEND and allows to keep track on vulnerabilities in the code base.
[Tool is used across the whole project team and is a main source of information about builds and pipelines.]

Solution: I've created a custom web application that helps to keep track on team updates and presents current tasks in per-member manner.
[Tool is used across the whole project team and beyond.]

Working as a technical leader in a team of 11. I'm also a people leader for 6 direct reports (devs). Most of the time I work with .net (especially net8), Kubernetes, AWS, Marklogic and Redis.
Applications I'm working on are both APIs and backend data processing services. We're using RabbitMQ as a main queuing system and use it with both NServiceBus and MassTransit. I'm developing set of tools that are used across the project team, like: in-house Monitoring system, Azure Devops pipelines monitor and Azure Devops team work tracker.
