I need a confident Node.js developer who can jump straight into the server code with me. We will lean heavily on Cursor/claude/antigravity as our day-to-day AI assistant, so prior experience prompting and steering that tool is essential. Our shared focus is to wire the backend to Microsoft Graph, expose clean REST endpoints, and make sure every call is authenticated, logged, and persisted. Concretely, the backend must support: • User authentication • Database management • API integrations PostgreSQL is the Database. Your job will be to flesh it out, write the data-access layer, and keep performance in mind from the outset. On the Microsoft Graph side, we’ll be handling email, calendar, so familiarity with the Graph SDK for Node or crafting raw OAuth calls will help us move fast. I’ve set up a GitHub repo with an agile workflow—short feature branches, pull-request reviews, and CI tests. Expected deliverables include the TypeScript/JavaScript code you write, accompanying unit tests, concise inline docs, and any setup notes needed to spin up the service locally or in our staging environment. If pair-programming, rapid iteration, and AI-assisted coding sound like your idea of fun, let’s do this.

Greetings, I understand you need a Node.js/TypeScript developer to collaborate directly on your backend, integrating PostgreSQL, Microsoft Graph (email, calendar), and AI-assisted workflows via Cursor/Claude/Antigravity, with authenticated, logged, and persisted REST endpoints. To align scope, a few quick questions, 1. Are we standardizing on the Graph SDK for Node or using raw OAuth calls selectively, 2. Do you prefer the data-access layer to be built with an ORM (Prisma, TypeORM) or raw queries for performance, 3. Should logging and metrics be centralized via a service (e.g., Grafana/ELK) or minimal local logs for now, Our delivery team includes Node.js developers experienced with TypeScript, PostgreSQL schema design, Graph API integrations, RESTful service patterns, CI/CD workflows, and AI-assisted coding practices. We handle authentication, logging, performance optimization, unit testing, and clear documentation. Let us chat so we can review Graph endpoints, database schema, and pairing workflow, the bid amount is a placeholder to submit. Our estimate is higher than your selected budget but we can discuss thru' chat, so for now you may ignore it. Regards, Yasir LEADconcept PS: We can share Node.js + Graph API integrations, TypeScript data-access layer examples, and AI-assisted coding workflows on request.

Hello, I can jump straight into your Node.js backend and work with you in a true pair-programming flow using Cursor, Claude, and Antigravity — I use these tools daily, so steering AI-generated code, shaping prompts, and rapidly iterating in feature branches will be completely natural. The shared goal is clear: wire up Microsoft Graph (email + calendar), expose clean REST endpoints, and ensure every call is authenticated, logged, persisted, and performant. Here’s what I’ll deliver: • Authentication layer (OAuth/JWT) with secure session handling • PostgreSQL data-access layer built with TypeScript best practices and optimized queries • Microsoft Graph integration via SDK or raw OAuth (tokens, refresh logic, retries) • Structured REST endpoints for email, calendar, and user workflows • Unit tests (Jest), clean inline documentation, and setup notes for local/staging runs I’m comfortable moving quickly inside an agile repo — short branches, focused PRs, and tight feedback loops. Performance and clean architecture come first, so the service remains stable as we scale out features. Extra Value Included: ✅ 24-hour support during active build ✅ 3 months of free post-production support ✅ Fast deployment assistance across AWS environments If AI-assisted, high-velocity backend development sounds like a fit, I’m ready to clone the repo and begin our first pairing session. Best, Jenifer

Hi I can jump directly into your Node.js backend and work collaboratively with you while leveraging AI tooling like Cursor, Claude, and Antigravity for rapid iteration. The main technical challenge is securely wiring Microsoft Graph to a clean REST layer while ensuring authentication, logging, and persistence remain consistent across all endpoints, and I solve this by implementing a structured middleware pipeline with OAuth flows, audit logs, and typed data models. I’ll extend your PostgreSQL schema, build an efficient data-access layer using Knex or Prisma, and optimize queries to maintain performance from day one. For Microsoft Graph, I’m comfortable with both the official Node SDK and crafting raw OAuth requests when needed for fine-grained control. Unit tests, inline documentation, and CI-ready code are a natural part of my workflow, especially in agile, branch-based repos. Pair-programming and iterative feature building are approaches I enjoy, particularly when enhanced by strong AI assistance. Thanks, Hercules

Dear Hiring Manager, I’m confident working directly within a Node.js/TypeScript backend and collaborating through an AI-assisted workflow (Cursor, Claude, Antigravity). I’m comfortable pair-programming and iterating quickly to build a secure, scalable service. Proposed implementation approach: • Implement Microsoft Graph integration with OAuth, token refresh, and scoped permissions • Architect PostgreSQL with a clean data-access layer and performance-focused indexing • Develop REST endpoints with authentication, validation, logging, and structured error handling • Configure CI, write unit tests, and maintain clear inline documentation • Add activity logging and persistence for all Graph interactions Queries: 1. Is the Azure App Registration already configured with required Graph scopes? 2. Do you prefer Prisma, Knex, or raw SQL for the DAL? 3. Should we follow a specific logging format (OpenTelemetry/JSON logs)? I will be looking forward to hearing from you. Kindest Regards
