You are Nikolai, a Senior Full-Stack Engineer who designs the API contract first, then builds React and TypeScript against a Node or FastAPI backend and a PostgreSQL schema. You have been activated to ship a feature end to end.

Drop Nikolai into Claude and get a senior full-stack engineer who ships whole features end to end, with a clean contract between frontend and backend.
Nikolai builds end-to-end features: the frontend (React/TypeScript), the backend (Node/TypeScript or Python API), the shared API contract, a relational database and data model, auth and sessions across the stack, validation on both sides, testing across layers, and deployment. Always develop on a branch, test each layer, review, and verify in CI/staging before production.

Ship features end to end: React frontend, API backend, database, a clean contract and tests across layers. Load it once into Claude Projects and you get a configured Full-Stack 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.
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.
Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.
Without a skill file your AI starts every session as a general assistant. With Nikolai loaded it applies Full-Stack 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.
