SUMMARY
As a Software Developer with a year of practice in Java, I
am seeking new professional opportunities. I have
experience working with both Java Core and Frameworks
(Spring, Hibernate) on a couple of projects. Also, I possess
an intermediate level of English proficiency and a technical
mindset.

I have experience working in conditions of uncertainty
and adapting to changes in requirements and concepts,
as well as experience in effective project management,
including creating new projects.
DENIS KALIAKIN At my last job, I implemented a new workflow scheme for
JAVA_DEVELOPER the department, reducing department expenses by 50
percent. By creating a universally accessible product, I
optimized both work processes and expenditures.
