Project details
I will build a custom REST or GraphQL API backend with Node.js, TypeScript, and MongoDB — clean, scalable, and production-ready.
What you will get:
• REST API, GraphQL API, or both — based on your needs
• Node.js/Express with TypeScript for type safety
• Prisma ORM with MongoDB or PostgreSQL
• Authentication: JWT, API keys, or OAuth
• Role-based access control (RBAC)
• Rate limiting, input validation, and error handling
• Swagger/OpenAPI documentation
My tech stack: Node.js, Express, TypeScript, Prisma, MongoDB/PostgreSQL, JWT, Swagger, Docker.
Why choose me:
• Built GitHub Insight Engine: open-source API with REST + GraphQL, 1,340+ signed requests, 194 repos indexed
• Shipped Telemetry Gateway: API serving 9 projects, 10,900+ events, with API key auth and SSE streaming
• Every API I build includes proper documentation, testing, and security from day one
I build APIs that scale. Send me your requirements and I will provide a detailed technical plan within 24 hours.

About Lucas
MCP Server Developer | Anthropic Certified | TypeScript & Node.js
Paris, France - 1:27 pm local time
What I've shipped:
→ AI-powered SaaS platform serving 60,000+ documents across 4,100+ accounts (Postle AI)
→ Telemetry gateway infrastructure shared across 9 projects — 10,900+ events processed (Prisma/MongoDB/SSE)
→ GitHub analytics engine indexing 194 repositories with 1,340+ queries served (REST + GraphQL + MCP layer)
→ AI assistant with full auth pipeline handling 886+ signed API requests (Aliatech)
If you need Claude or any AI assistant to interact with your APIs, databases, or internal tools — that's exactly what I do. I handle the full scope: API mapping to MCP tools, auth pass-through, rate limiting, error handling, monitoring, and deployment.
Stack: TypeScript, Node.js, Next.js, Prisma, MongoDB, Docker, Claude API, MCP SDK.
Available 30+ hrs/week. Based in France, I work in English and French across all time zones. Happy to start with a small paid trial so you can evaluate my work before committing.
Steps for completing your project
After purchasing the project, send requirements so Lucas can start the project.
Delivery time starts when Lucas receives requirements from you.
Lucas works on your project following the steps below.
Revisions may occur after the delivery date.
API Design & Schema Planning
I analyze your requirements, design the API endpoints and data model, choose REST or GraphQL (or both), plan the database schema with Prisma, and deliver a technical specification document.
Database & Authentication Setup
I set up the project structure, configure Prisma ORM with your database (MongoDB or PostgreSQL), implement authentication (JWT, API keys, or OAuth), and build the role-based access control layer.
