Summary of Qualifications

I have worked in Software engineering industry for almost eight year dealing with very different types of products – from long-term legacy systems to brand new distributed applications built from scratch. I have experience in worked with different specific frameworks such as for eCommerce direction, billing systems, user portals.

I have a solid background in theoretical (OOP, design patterns, integration patterns) and practical (business requirements analysis, system design, source management, build infrastructure) aspects of development and delivery for Java-based systems. Also I have strong experience with database development and administration.

I used to work with multiple Java platform versions – from 5 to 8, thus multiple frameworks stacks and have practical experience of upgrading long-term systems technological stack without losing quality in customers and users service.

I also have two years of experience for being team lead and introducing best practices to existing team processes and adjusting it to give most efficient results in product delivery.

I’m really found of working in small cross-functional team with proactive open-minded people who are motivated for delivery technical excellence with the software hey build, ready for challenging and non-trivial task and do not afraid of taking both liberty and responsibility in decision making process.
