Andrii Danylovskyi
Senior C++/Qt/Android Developer

Summary of I have more than 13 years of experience in software development. I have worked in US
Qualifications and German companies where I was involved in creating desktop and mobile client-
server applications. I had a chance to work with different types of applications and on
different stages of the applications lifecycle, this experience allows me to work in
different environments, not only building applications from scratch but also working as
a support team for an existing solution, fixing issues and enhancing functionality. I have
a great knowledge in such technologies: C++, Qt, QML, Java, Kotlin and Python including
multithreading, networking, DB etc. I also have hands-on experience working with
embedded and IoT platforms including Raspberry Pi, Arduino and ESP32; have good
knowledge of Scrum methodology.
During my career I have worked on features design and development, coding,
debugging, testing, building, and deploying processes and maintenance.
I always was interested in IT, that is why I received this kind of education. I am a
motivated, result-oriented, and self-driven person, a good team player. Equipped with
excellent communication skills, work ethics and passion to develop, always eager to
help teammates. I'm an agile person and always try to learn and use something new.

Experience

A learning management system for creating, assigning, delivering, and
tracking professional training

Project The app is designed to support the complete learning lifecycle for administrators,
Description authors, and learners. Administrators can manage users, audiences, enrolment
requests, audience-based assignments, reporting, certificates, and renewals. Authors
can create versioned courses, documents, videos, assessments, and learning paths.
Learners can enrol in available training, complete course content and assessments,
resume progress, receive certificates, and track renewal requirements.

A key focus was building clear, role-based workflows and a consistent, accessible user
experience across the administration, authoring, and learner workspaces. The platform
also supports publishing control, assessment retries, progress tracking, generated
certificates, and multilingual French/English UI.
