GraphQL Developer
GraphQL Developers design and implement flexible query APIs that allow clients to request exactly the data they need. Their English work involves explaining schema design decisions to frontend teams, justifying federation trade-offs in architecture reviews, documenting resolver behaviour, and discussing performance optimisations. This path covers the vocabulary for designing, communicating about, and debugging GraphQL APIs.
Topics covered
- Schema design
- Resolver patterns
- Federation & composition
- Performance: N+1 & DataLoader
- Subscriptions & real-time
- Security & authorisation
Vocabulary spotlight
4 terms every GraphQL Developer should know in English:
A function responsible for fetching the data for a single field in a GraphQL schema — every field that returns data has a resolver
"The user resolver makes one database query; the posts resolver makes one per user — that's the N+1 problem."
A performance anti-pattern where fetching a list of N items triggers N additional queries (one per item) instead of a single batched query
"Loading 100 users with their profile photos caused N+1: 1 query for users, 100 for photos."
A batching and caching utility that groups individual resolver calls within a single execution tick into a single batch request, solving the N+1 problem
"After adding DataLoader, 100 user requests became a single SQL IN clause instead of 100 queries."
An architecture where multiple GraphQL services each own a part of the unified schema and a gateway composes them into a single API for clients
"After federation, each domain team owns their subgraph schema independently — no more schema conflicts."

Frequently Asked Questions
What English skills do GraphQL Developers most need to improve?+
GraphQL Developers most commonly need to improve: technical vocabulary (the correct English terms for domain concepts), collocation accuracy (using the right verb for each action), written communication (bug reports, PR descriptions, technical docs), and spoken communication for standups, code reviews, and stakeholder meetings.
How long does the GraphQL Developer learning path take?+
The GraphQL Developer learning path contains 20–40 hours of material studied comprehensively. Most learners focus on the highest-priority modules first and return to the rest over time. Spending 30 minutes per day for 4–6 weeks produces noticeable improvement in workplace English.
What vocabulary should a GraphQL Developer prioritise first?+
Start with the vocabulary that appears most in your daily work — terms you read in documentation, use in commit messages, and hear in meetings. The GraphQL Developer path begins with the most frequent vocabulary clusters before moving to advanced communication patterns.
Are there interview exercises for GraphQL Developer roles?+
Yes. The GraphQL Developer path includes role-specific interview question modules with model answers and key phrases — the actual questions interviewers ask and the vocabulary needed to answer them fluently. There is also a dedicated Interview Practice hub for general interview skills.
Does this path include pronunciation help?+
Yes. The path links to pronunciation exercises for the technical terms most commonly mispronounced in this domain. The Pronunciation hub includes drills for acronyms, silent letters, word stress, and minimal pairs — all in IT context.
What are the most common English mistakes GraphQL Developers make?+
The most common mistakes: incorrect collocations (using the wrong verb with a technical noun), false friends from L1, tense errors when narrating past incidents or walkthroughs, and using overly formal or overly casual register in written communication.
How do I improve my English for code reviews?+
Learn the standard code review collocations: approve a PR, request changes, leave a nit, address feedback, block a merge, resolve a conversation. Use hedging language for suggestions: "This might be cleaner as…", "Have you considered…?". The Collocations section includes a dedicated Code Review set.
Can I use this path alongside my daily work?+
Yes — the path is designed for working professionals. Each exercise set takes 10–15 minutes. The most effective approach is to study a vocabulary module before a meeting or task where you'll use that vocabulary, then practise immediately after. Context-linked practice produces much faster retention.
Is the content free?+
Yes, completely free. No registration required, no payment, no time limit. All vocabulary modules, exercises, glossary entries, and learning path guides are open access.
How do I track my progress through this path?+
Progress is tracked in your browser's local storage — completed exercise sets are marked with a checkmark when you return. No account is needed. You can bookmark specific modules and use the exercises overview to see which sets you've completed.
