"Flexible and convenient" serves as a guiding principle for how the software should meet our client's needs. My primary focus is on cultivating a culture of collaboration and empowerment, inspiring talented teams to explore new possibilities and achieve excellence.

About Me

My name is Valentinos Papasavvas. I am sociable, energetic and friendly person. My interpersonal skills make me a good communicator, able to work well with others. I motivate and encourage people around me. I am self-aware and always seek to learn and grow. I am not scared of undertaking new responsibilities no matter the degree of difficulty. I am a critical thinker and a good researcher.

Currently, my main focus is on coaching teams and transforming startups to reach the next level. Day to day operations are:

  • Allocate resources, manage expectations and performance, and drive team efficiencies
  • Manage the use of technology stacks and ensures that team members grow their knowledge base, by utilizing Online courses and additional professional development
  • Participate in the hiring and onboarding process
  • Work with other business units to analyze trends and product needs for continues product improvement
  • Enhance engineering efficiency by closely observing the team and identify opportunities
  • Provide mentorship and technical guidance to teammates
  • Own development projects from conception through build, testing, implementation and support ensuring they meet business needs.
  • Manage QA resources to ensure through testing of all code before release. Utilising automated testing where possible.

We give emphasis on delivering a feature or a final product on time along with quality code. Each person evaluates and reviews code of others to guarantee the best result.

In my free time, I am an active and athletic person seeking for action and adventure all the time. I always look for new technologies and like to play and develop my own projects, in order to expand my knowledge and keep up to date with the latest technologies. I tend to play with latest technologies and programming languages, which some of them can be found in my Github page.

This resume was build by a module I wrote called Drupal Resume.
