Software Engineer of the Future
Hi! My name is Lena Sędkiewicz. I'm a software engineer (TypeScript, JavaScript, React, Node.js, Java) with a strong cybersecurity focus — backed by a background in psychology and cyberpsychology.
While programming, I connect the past and the future: gaining knowledge from books and courses, and writing code line by line, alongside discussions with AI and creating code with the help of models like Claude or Gemini. I use the latest technologies, while always remembering how crucial my knowledge — acquired through learning theory and project experience — is in using them.
I'm familiar with topics crucial for web developers: technical SEO and accessibility. In my professional journey, I've also had the opportunity to gain some knowledge about marketing and copywriting.
I share my programming, psychological, and cybersecurity knowledge as a speaker at conferences and meetups, by creating a podcast within the Not The Hidden Wiki community, on my blog, and occasionally as a lecturer.
Programmer Starlog - Blog
As a traveler through the universe of psychology and programming, I maintain a 'Starlog' - blog, which is a space for sharing knowledge, as well as a record of reflections and experiences.

Empty Head. How Intensive Learning Stunted My Creativity
Trying to level up from freelance "projects" to something more serious can demand a lot of sacrifices. In my case, one of them was sidelining the activities that relied on my creativity. On one hand, it helped me reach certain goals — but it also caused some real damage. In this post, I share reflections on a period that required those sacrifices.
