Programmer of the Future

Hi! My name is Lena Sędkiewicz. I program and develop in the area of fullstack technologies (JavaScript, TypeScript, React, NodeJS, Python) and cybersecurity.

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.
