What I Do

Android Development

Having an extensive experience in software development and being skilled in various languages, I mostly work in Kotlin and Java, but also have a firm knowledge in Node JS, Swift 5, Mongo DB, and pretty much everything client can ask for in mobile apps development.

Backend Development

Back-end code is crucial but largely ‘invisible’ part of any application. Building the logic behind the application, its architecture and internal design, and making it work has always felt like more of a challenge and still inspires me to learn and improve myself constantly.

Technical Leadership

Leadership is an art. Making decisions and taking responsibility for them is not easy, but it is necessary. Thus, I dedicated a lot of my time and efforts to master the skills of leading people towards common goals and ensuring technical excellence and the overall success of my team.

Team Management

Since I founded K7TECH, my passion became inspiring people, showing them their true potentials, guiding them to become the best versions of themselves and work as a part of an effective team. My role is to get to know every individual, define their responsibilities, organize team communication, at the same time continuously reminding everyone of our common vision and ideals.

Negotiating & Closing

The development of proper negotiation skills with the clients is of utmost importance and enables efficient closing of deals, leaving both sides satisfied in the process. Working with people usually represents much greater challenge than writing the code and it certainly has been a very significant area of my activity where I am able to constantly improve and learn about myself and others.

Business Strategy

Being a part of a startup project, I started learning about business strategies as a student, which prepared me to run a company. However, that has been a first step in ensuring the company’s success and sustainability, a process heavily dependent on constant improvement of my management skills and decisions made in order to maintain the desired image and direction of our business.


Petar and his team are hands down the BEST freelancers I have worked with on this website! He was able to complete this project quickly and with very little guidance! His excellent communication and dedication to this project made every interaction a pleasure. I plan on working with him again in the future to keep this project up-to-date!
