 Cover Letter
With 6 years of team leadership and 12 years of technical expertise, I am confident in
my ability to drive successful outcomes. I have led teams, fostered collaboration, and achieved
project objectives.

I have a solid background and experience in software development on Windows, Linux,
MacOS. I have over 12 years of commercial experience and am skilled in building distributed
systems for Desktop and Web applications, including high-loaded systems. I also have
experience with cloud technologies, (AWS, Azure, Google Cloud) and building cloud-native
applications.

My main technology stack includes .NET (C#), JavaScript, HTML, CSS, and SQL.
Secondary technology stack: Python, Node.js, F#, React, Angular, ElasticSearch.

In my previous engagement, I led a team of eight engineers for a startup, where I was
responsible for building development processes, conducting business analysis, and
understanding the client's marketing strategy to meet the project requirements for web
applications and browser extensions. As a result - our client received a subscription contract in
b2b and b2c sectors.
Team: (SE/ME) Developers, QA, DevOps, Automation QA, Product Owner, Delivery Manager,
Tech Lead.

In a recent engagement, I was involved in the development of a custom ORM for a
Desktop resource management application as a Team Lead. My team successfully performed
effective refactoring, achieved unit test coverage in .NET and C#. I have established
communication with the client from the first week to ensure the specified service was delivered
within the set requirements and deadlines.
Team: (Architect/SE) Developers, Product Owner (Senior Architect).

I also possess strong leadership skills and have a solid background in mentoring.
I have established free IT courses for students in collaboration with Odesa National Polytechnic
University, and I have already mentored more than 100 engineers, enabling them to start their
careers in IT. This is how I choose to spend my free time because I believe that continuous
learning is a crucial aspect of our lives.

I am stress-resistant, agile in learning new technologies, and am not afraid of facing
challenges.
