About Kostas Retalis

I am Kostas, a Frontend Developer with a strong background in digital agencies and SAAS companies, currently focusing on the frontend (mainly vue js), always looking for new things to explore.I am a generalist, having a broad spectre of knowledge, but I also like to deep dive and specialize into specific technologies that I work on for a while.I really like to stick to best practices, ensuring that my work provides long term benefits and minimal tech debt. I trully love being in a team that I can both take and give technical value and also have a good understanding and communication in general.I love scaling and architecture, looking forward to find the opportunities to include them more in my day to day work.
