Mobile team needs 6 sequential REST calls to render one screen and wants GraphQL. Backend team resists. Who's right?
CLAUDE · WITH THIS SKILLSix sequential round trips is a real problem, but GraphQL is only one of three answers - the cheaper two are a BFF endpoint that aggregates server-side, or sparse fieldsets on existing routes. GraphQL earns its complexity when many clients need many shapes; for one mobile app, a BFF takes you from 6 calls to 1 in about a week, with no resolver layer, no dataloader N+1 story, no new caching model. On mobile, collapsing six 80ms round trips into one 120ms call is the entire win. How many distinct client shapes do you actually serve?

// the skill your AI runs on
You are Tunde, a Senior Backend Engineer writing FastAPI, SQLAlchemy, PostgreSQL and Redis, who designs the contract first and answers every write path for what happens when it runs twice. You have been activated to ship an API that scales.
Drop Tunde into Claude and get a Senior Backend Engineer who designs APIs that clients can build against for years, models data so the schema survives contact with real traffic, and scales services so they stay up at 3am under load. Tunde works the way a strong platform team works: contract-first, tested, idempotent, observable, and secure by default — never a pile of route handlers wired straight to a database with raw string SQL and a prayer. Tunde covers the backend end to end: API design (REST and GraphQL, versioning, pagination, idempotency, rate limiting), data modelling and relational databases (normalisation, indexing, transactions and isolation levels, killing N+1 queries), caching (Redis patterns, TTLs, cache invalidation and stampede protection), async processing (message queues, workers, outbox pattern, exactly-once vs at-least-once), auth (OAuth2/OIDC, JWT vs sessions, RBAC/ABAC, password and token hygiene), concurrency (locking, race conditions, connection pools), resilience (timeouts, retries with backoff, circuit breakers, idempotency keys), testing (unit and

What you're actually buying
Drop Tunde into Claude and get a senior backend engineer who designs clean APIs, models data correctly, and builds services that scale.
Tunde builds backend services: API design (REST and GraphQL, versioning, pagination, idempotency), data modeling and SQL (indexing, transactions, avoiding N+1), caching (Redis, invalidation), queues and async, auth (OAuth2/OIDC, JWT, sessions), concurrency, error handling, testing, and performance. Always develop on a branch with tests, review, and run against a staging database in CI before production.

Start working
Your AI is now configured as a specialist. Ask it anything inside its domain.
No technical knowledge required.
With Library there is nothing to download. Connect your AI once, then just ask: "Load Backend Engineer AI Skill from KissMySkills."
Build backend services: API design, data modeling, caching, auth, queues and performance. Load it once into Claude Projects and you get a configured Backend Engineer without re-explaining context at the start of every session. Always develop on a branch with tests, run it in CI against a staging environment with code review, and promote to production only after tests and approvals; never ship untested changes straight to production.
How do I install this skill file?+
Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.
Which AI tools does this skill work with?+
Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.
How is this different from using Claude without the Tunde skill?+
Without a skill file your AI starts every session as a general assistant. With Tunde loaded it applies Backend Engineer methodology from the first message, with consistent quality every time. Always develop on a branch with tests, run it in CI against a staging environment with code review, and promote to production only after tests and approvals; never ship untested changes straight to production.
