The journey.

1. Jul – Dec 2025

   Notebooks to NumPy

   The channel finds its footing by sharing ML tools, praising MLflow for tracking experiments and pointing to a free data science course at wqu.edu. By December it has published its own Medium posts on a neural network built with only NumPy and on embeddings, inviting corrections.

   One day at a time

   A 100-day self-development challenge gets logged one numbered day at a time: binary search, half of Grokking Algorithms, graphs and recursion. In June the channel invites readers into a month of LeetCode daily challenges, and by Day 67 it is on dynamic programming and reading up on Fenwick trees.

   Project days

   The numbered days turn into project days: when the first approach does not work, a mini version with a new approach is built, then scaled up and given a waitlist. Along the way the channel notes that the hardest part of building an AI project is a strong knowledge base, and shares a sneak peek of a portfolio rebuild.

   Go, Kubernetes and a pause

   After a break, the channel returns with its first open source contribution, all three lines of it. It publishes a fourth blog on RAG, logs learning Go and system design, tries Kubernetes for the first time and joins a competition to start modeling. In October something with an over-engineered backend finally goes live, and the channel announces it will be inactive on Telegram for six months.
