MY JOURNEY

Every step from the first line of code to today.

2019

GAME START

First Contact

First encounter with Python. print("Hello World") ran on screen — didn't understand why, but loved it. The feeling of making the machine do exactly what you want, impossible to explain.

Backend Clicked

RESTful APIs, databases, Docker. Built a server from scratch for the first time — request comes in, response returns exactly as intended. Realized this was what I wanted to do seriously. React and Next.js followed.
