Three separate tracks, browser-native runtime — practice in-tab, see results instantly. Pair them with Python for full-stack, or learn just the one you need today.

Learning path

From zero to interview-ready — typical 12-month path.

A structured 3-stage curriculum. Not a video dump — a real plan that builds job-ready Python skills. Timing varies by background and effort.

What you'll build

Portfolio-grade Python projects.

Each Project Studio build is interview-defensible: milestones, rubrics, STAR talking points. Walk into the interview with a real resume bullet.

Level 28-15 h

Multi-user TODO API with JWT auth

This is the most common junior backend interview project on the planet: REST API, auth, persistence, tests. Builds the muscle hiring managers screen for first.

Level 325-40 h

AI Telegram bot with conversation memory & tool use

AI Engineering is one of the fastest-growing junior areas right now, and the entry signal teams look for is 'has shipped a real LLM-backed system, not a demo'. This project covers the whole stack — API integration, memory, tools, deployment, evals — in one resume bullet.

Level 460-100 h

News feed at scale — fan-out, caching, 10K writes/s ready

This is a classic large-scale system-design interview problem you'll see at top engineering teams. Building it for real — not just whiteboarding — turns 'I've read the book' into 'I've shipped it'. A strong signal a junior can carry into a more senior-leaning interview.

Level 210-18 h

Markdown blog engine with RSS + sitemap

Every developer eventually wants their own blog. Building it from scratch teaches HTTP serving, templating, content modelling, SEO basics (RSS / sitemap / OG tags), and deploy. It's the simplest project that touches all the things a junior backend engineer should know.

Level 320-35 h

Slack bot that summarises threads with Claude

Slack is the home of long, context-heavy engineering discussions. A 'TL;DR this thread' button is the single most universally wanted Slack feature. Building it teaches OAuth flows, async message handling, prompt engineering for anchored summaries, and the security discipline of multi-tenant SaaS.

Level 450-85 h

Recommender system — collaborative filtering at million-row scale

Recommenders are everywhere — Netflix, Spotify, Pinterest, Amazon. Building one end-to-end teaches the rare combination of ML modelling AND production system design. This is the L4-tier portfolio piece that signals 'ready for senior IC' on resumes.
