30-Day English for Backend Developers
Complete Learning Path

This path is designed for backend developers at any level who work in English-speaking teams or communicate with international colleagues. It covers the specific vocabulary and communication patterns you encounter daily: API documentation, code reviews, architecture discussions, and technical interviews.

The path is designed for B1–B2 English learners (intermediate). You should be able to hold basic conversations in English. The path will improve your professional and technical English, not teach you English from scratch. If you are unsure of your level, try Day 1 — if the vocabulary feels completely unfamiliar, consider building general English skills first.

Each day is designed for 20–30 minutes: roughly 10 minutes on the vocabulary exercise and 15 minutes on the communication or skills exercise. Optional blog reading adds another 10–15 minutes if you want to go deeper. Consistency is more important than duration — 20 minutes every day beats 2 hours once a week.

The path covers backend development vocabulary (APIs, databases, authentication, git), architecture language (microservices, distributed systems, design patterns), daily communication (standups, code reviews, async messages, incident response), and career vocabulary (technical interviews, salary negotiation).

Yes. Days 16, 26, and 30 focus specifically on speaking: standup phrases, technical interview speaking, and mock interview practice. These days link to speaking exercises with example dialogues and pronunciation practice for common technical terms.

Yes. If you are already confident with, for example, git vocabulary, you can skim Day 8 or replace it with a more challenging topic from later in the path. The structure is a guide — use your judgment about where you need the most work.

The guide at /guides/backend-developer/ is a comprehensive reference document explaining the English of backend development. This learning path translates that knowledge into a day-by-day action plan with specific exercises. Use the guide for understanding, the path for practice.

Day 5 and Day 28 focus on code review language. The exercises include writing PR comments, responding to feedback, and using diplomatic disagreement language. See /exercises/code-review/ for the full set of code review exercises.

Yes. Weeks 4 and 5 (Days 21–30) cover advanced topics including distributed systems, performance, incident response, and technical interview preparation — areas that are especially relevant for senior and staff-level engineers who need to discuss architecture trade-offs and lead technical discussions.
