Our production app sits on GCP and is powered by ReactJS, a NodeJS + GraphQL API, and a growing suite of AI features—Generative models, automation pipelines, and Agentic AI modules. I now need an experienced engineer who can work end-to-end while leaning heavily on Claude Code and/or Cursor to accelerate delivery. Your day-to-day will blend feature work and refactoring. The immediate priority is the NodeJS/GraphQL layer: tightening schema design, optimising resolvers, and exposing new endpoints that our AI services can consume. On the AI front, you’ll iterate on: • Generative AI models that serve personalised content • Automation processes that cut manual ops out of the loop • Agentic AI implementations that chain and orchestrate tasks You’ll still touch the ReactJS front-end when integration demands it, but most momentum is in the services tier and AI modules. Expect to pair with our existing ML engineer when prototyping, then own the production build, tests, and deployment through our GCP CI/CD. Acceptance criteria for each sprint are simple: a green test suite, merged PRs, and working cloud deploys behind a feature flag. If you’re comfortable navigating the full stack with Claude Code or Cursor as force multipliers, I’d like to start our first milestone this week.

Hi — Elias here from Miami. I see that you're looking to enhance your AI platform on GCP with a tech stack that includes ReactJS and a NodeJS + GraphQL API. The real challenge often lies in ensuring seamless integrations and maintaining scalability as user demand grows. What usually matters most here is how well the system can adapt to changes in both data and user roles, especially as AI components evolve. This task can look straightforward initially, but addressing state management and permissions effectively is crucial to avoid bottlenecks down the line. My approach would involve designing a modular architecture that prioritizes maintainability and stability. This way, we can incorporate future updates or features without significant rewrites. I’ve worked on similar platforms, focusing on stability and performance, which has equipped me to anticipate potential pitfalls. A few questions to better understand the scope: Q1 – How do you envision user roles and permissions being managed within the application? Q2 – What integrations with other services do you foresee as critical for this platform? Q3 – Are there specific scaling expectations or performance benchmarks you aim to meet? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Your GCP-based ReactJS, NodeJS/GraphQL, and AI platform is a strong match for my background. I’ll start with the services tier: review the schema and resolver patterns, identify query and mutation bottlenecks, add the endpoints your generative and agentic modules need, and cover the changes with focused tests. I’ll use Claude Code or Cursor for rapid iteration while still reviewing the generated code carefully and keeping the architecture maintainable. For the AI work, I can help prototype with your ML engineer and then turn those experiments into production services, including personalised content generation, automation pipelines, and task-chaining agents. I’ll also handle React integration where required, feature-flagged rollout, CI/CD checks, and GCP deployment verification so each sprint ends with green tests, merged PRs, and a working cloud build. My relevant production experience includes DeskLeap, a Shopify App Store SaaS with a public REST API, ClearAgent, a live multi-tenant customs-clearing platform, and an AI outreach system that discovers businesses, scrapes contacts, generates personalised emails, and manages paced SMTP delivery with unsubscribe handling. I can begin this week and work end-to-end across implementation, testing, refactoring, and deployment. Should the first milestone focus primarily on GraphQL optimisation and AI-service endpoints before expanding the agentic modules? Muhammad Saad

Hi! This is something we can definitely handle, and the stack and workflow you're describing is terrain we're comfortable with. Before we start the first milestone, the one thing I need to understand is how the AI modules are currently structured: are the agentic pipelines and automation processes already separated into discrete services, or are they embedded inside the GraphQL layer? The answer changes where we'd focus first — if they're entangled, the schema work and the AI refactoring need to move together rather than sequentially, which affects how we'd plan the initial sprint. On how we'd approach the rest: the GraphQL side — schema tightening, resolver optimisation, exposing clean endpoints for AI consumption — is straightforward for us. For the agentic and generative layers we work with the Anthropic SDK and Claude API directly, so Claude Code as a force multiplier fits naturally into our process rather than being something we'd need to ramp up on. For the ReactJS integration work, we'd keep frontend touches scoped to what the service tier actually requires and avoid scope creep there. GCP CI/CD with feature flags and a green test suite as acceptance criteria is a clean, familiar rhythm. The collaboration model with your ML engineer during prototyping and then owning the production build is exactly the kind of handoff structure we work well in. Gustavo & the DoTheCode team

Hi, I am Adeel. I built Boostifai, an AI SaaS with a React front end and a Node and Python services layer doing generative content and automation, so the mix of GraphQL resolver work and AI orchestration here is familiar territory. I would start by tightening the schema around the endpoints your AI modules actually consume, then wire agentic tasks behind feature flags so each one ships independently and stays testable. I use Cursor daily for exactly this kind of pairing between service code and model integration, so ramping into your CI/CD should be quick. Are the Agentic AI modules calling a single model provider right now, or several?

Hello!, I am a Florida-based senior software engineer, and your project stands out because the real challenge is not just “adding AI” but making sure it fits cleanly into your existing GCP stack, ReactJS app, and NodeJS + GraphQL API without breaking production stability. I’d approach this in practical phases: 1. Review your current architecture, API flow, and AI touchpoints 2. Identify bottlenecks, data flow issues, and where AI can add the most value 3. Implement the feature cleanly in small testable steps 4. Validate performance, error handling, and deployment safety before rollout I work best on systems like this because I pay attention to the details most people skim past, especially around API contracts, state handling, and keeping the app maintainable after launch. Relevant work I’ve handled includes: - AI dashboard for a logistics SaaS - React/Node analytics platform for a fintech startup - GraphQL-powered admin portal for an e-commerce tool - Internal AI workflow system for a B2B ops team A couple quick questions so I can estimate the right path: 1. What exact AI feature(s) are you adding first, and what should the user experience look like? 2. Is the current GraphQL layer already structured for these new workflows, or should I help extend the schema too? 3. Are there any GCP services, auth rules, or deployment constraints I should respect from day one? If you want someone who will actually read the details and build it cleanly, I’m ready to jump in. -James

The interesting constraint here isn't the AI features themselves - it's that your GraphQL schema has to stay stable enough for the frontend while it's also becoming the contract your AI services consume, which means schema changes now carry two audiences instead of one. I've worked with Node/GraphQL/React on GCP with AI features layered on top (generative content, automation pipelines, agentic modules), so I'm used to the pattern of keeping resolvers thin and pushing orchestration logic for agentic chains into dedicated services, rather than letting it bleed into the API layer. That's usually what keeps the schema clean as the AI surface grows. I use Claude Code and Cursor daily as part of my actual workflow, not just for boilerplate - mainly for resolver refactors, test scaffolding, and speeding up the review loop before a PR goes out, which fits your acceptance criteria of green tests and merged PRs per sprint. I'd start by looking at how the current resolvers expose data to the AI modules - whether it's request/response or if any of the agentic work needs streaming or async job patterns - since that shapes how I'd approach the endpoint work first. Quick questions: are the agentic modules currently orchestrated in-process, or through a separate service/queue? And is there an existing eval or test harness for the generative outputs, or is that something to help set up? Juan Pablo

Hi, Mateo here, from Toronto. A GraphQL layer serving AI features only stays fast as the agentic modules grow if resolvers are designed with clear data-loading boundaries from the start, otherwise chaining multiple AI tasks through one schema tends to create N+1 query problems that surface only once traffic picks up. You mentioned wanting to tighten schema design and optimise resolvers as the immediate priority, so I would start there, profiling the current GraphQL layer before touching the AI modules, since a slow resolver underneath an automation pipeline just multiplies the latency every time an agent chains a task. I work comfortably across Node.js, GraphQL, and React, and I actively use Claude Code and Cursor as part of my workflow, reviewing generated output the same way I would review any code before merging, so speed never comes at the cost of correctness. Would you want the first milestone focused purely on schema and resolver optimisation, or paired directly with one of the AI modules from day one? Looking forward to working with you.

Hi, I’d love to help with your ReactJS + NodeJS/GraphQL + GCP application and contribute to the AI-focused development roadmap. I can help with: • GraphQL schema and resolver optimization • NodeJS APIs and AI-service integrations • ReactJS frontend integration • Generative AI and automation workflows • Agentic AI task orchestration • Testing, refactoring, and production deployment • GCP CI/CD and feature-flagged releases I’m comfortable using Claude Code and Cursor as development accelerators while maintaining clean, reviewed, production-ready code. A few quick questions: 1. What AI models/services are currently being used? 2. Which GraphQL framework and database are you using? 3. Are the Agentic AI modules already prototyped, or would I build them from scratch? 4. What is the scope of the first milestone? I’d be happy to review the current architecture and start with the first milestone this week.

The immediate risk in your setup is that AI feature velocity can outrun the service layer, especially when GraphQL schemas and resolvers were not originally designed for heavier orchestration. I’d focus first on the API layer so new AI endpoints, automation jobs, and agent flows have a cleaner contract to build on. My background fits this kind of work well: NodeJS services, React integration touchpoints, API refinement, and cloud deployment workflows where each sprint still has to end with passing tests and safe releases. I’m also comfortable using Claude Code/Cursor practically as accelerators, not as shortcuts that leave messy production code behind. I can also help identify quick refactors that reduce future friction before more AI modules get added. - Is the first milestone centered mostly on resolver optimization, or on shipping net-new AI-facing endpoints? - Do you already have feature-flag tooling in place on GCP, or should that be part of the implementation approach?
