We are building a next-generation workflow automation platform that combines deterministic business rules, artificial intelligence, document intelligence, and human review workflows into a single operating system. This is not a traditional CRM project. Our vision is to develop a doctrine-driven platform where business rules serve as the system authority, AI serves as an analytical and drafting layer, and human reviewers serve as the final compliance checkpoint. We are seeking an experienced engineer or engineering partner who can help architect and build the platform from the ground up. Project Objectives The platform will: • Ingest and analyze large volumes of structured and unstructured documents • Extract data from reports, PDFs, and supporting documentation • Apply rule-based workflow logic • Generate AI-assisted recommendations and draft outputs • Maintain complete audit trails and workflow transparency • Route work through human review checkpoints • Support future deployment of local AI infrastructure for privacy and performance Core Architecture The system will be built around four primary layers: 1. Rules Engine * Deterministic business logic * Workflow orchestration * State management * Trigger and escalation logic * Audit tracking 2. AI Layer * Document analysis * Classification * Pattern detection * Summarization * Draft generation * Structured outputs 3. Local Processing Layer * OCR * Document parsing * Data extraction * Vector search * Local inference capabilities * Privacy-first processing 4. Human Review Layer * Quality assurance * Workflow approvals * Compliance review * Exception handling Initial Development Priorities Phase 1 • User authentication • Client record management • Document upload system • OCR and document extraction • Workflow engine • Rule-based status management • Review dashboard Phase 2 • AI-powered document analysis • Automated classification • Recommendation engine • Draft generation workflows • Response parsing Phase 3 • Local AI infrastructure • Vector database integration • Knowledge retrieval system • Multi-agent workflow orchestration • Advanced automation Desired Technical Experience Required • React / Next.js • Node.js, Python, or similar backend framework • PostgreSQL or equivalent relational database • REST APIs • Cloud infrastructure (AWS, Azure, or GCP) • Workflow automation systems • Document processing pipelines Preferred • OpenAI APIs • Anthropic APIs • Retrieval-Augmented Generation (RAG) • LangGraph, LangChain, or similar frameworks • Vector databases • OCR technologies • AI agent architectures • NVIDIA AI ecosystem • Local model deployment What We Are Looking For We are not looking for someone who simply builds forms and dashboards. We are looking for a builder who understands how to combine: • Rules engines • Artificial intelligence • Workflow automation • Human review systems • Scalable software architecture The ideal candidate enjoys solving complex business process problems and translating expert decision-making into software systems. Engagement Structure Open to: • Fractional CTO • Lead Architect • Senior Full-Stack Engineer • AI Systems Engineer • Development Agency • Long-term strategic technology partner To Apply Please provide: • Relevant project examples • Experience building workflow automation platforms • Experience with AI-powered applications • Technology stack recommendations • Estimated availability • Preferred engagement structure

We are seeking a Mid to Senior-level Fullstack Developer (3–5 years of experience) to not only maintain and expand our platform (Next.js frontend + Django backend) but also guide us in fully integrating AI-powered coding assistance across the full stack. The frontend is already set up for AI-assisted editing (e.g. Cursor), and we want to evolve our backend similarly. The ideal candidate will help us transition the entire development environment, so both we and the developer can leverage state-of-the-art AI coding tools. Beyond coding, you’ll act as a mentor, helping us better understand the backend’s architecture and workflows while integrating AI-driven development tools into our process. You’ll have a key role in making our stack both stable and future-ready, with AI-assisted flexibility. The Context Our frontend was recently ported to Next.js in an ad-hoc manner, leaving certain sections in need of refactoring and stabilization. We have committed to keeping our backend in Django to leverage its robust processing capabilities. You will be the point person for bridging these two environments. Key Responsibilities -Maintenance & Stability: Perform routine maintenance and optimization across the full stack. -Bug Fixing: Identify and resolve issues within the existing Next.js frontend and Django backend. -System Reliability: Provide technical support and troubleshooting during system downtime. -Feature Implementation: Build and deploy new features, ensuring seamless integration between the AI pipeline and the user interface. Required Technical Profile -3–5 years of professional fullstack experience. -Frontend: Proficiency in Next.js and React; experience cleaning up/refactoring "messy" or legacy codebases is a plus. -Backend: Strong experience with Django (Python), specifically working with complex data pipelines or API integrations. -Mindset: A pragmatic approach to coding—balancing the need for new features with the necessity of technical debt reduction.

We need a developer to build a simple AI chatbot MVP using Next.js and the OpenAI API. The chatbot should allow a business owner to enter FAQ or support content, then let users ask questions through a chat interface. The AI should answer based only on the provided content.

We’re looking for a strong UX engineer to improve the design, usability, and polish of an existing therapist directory / marketplace product. The product is built in Next.js / React / Tailwind / Supabase. It is already functional, but needs a sharper, more trustworthy, more modern user experience across the public directory, therapist profile pages, search/browse flows, and provider dashboard/admin areas. This is not a greenfield design-only project. I’m looking for someone who can both think through UX and make high-quality frontend changes directly in the codebase. What you’ll work on • Improve the overall visual design and UX of the site • Redesign key pages: homepage/directory, search results, therapist profile pages, provider dashboard • Improve spacing, typography, mobile responsiveness, CTA hierarchy, and trust signals • Make the site feel polished, professional, and conversion-focused • Work in a staging environment with production-like data • Submit clean GitHub commits / PRs Ideal candidate • Strong product/design taste • Excellent React / Next.js / Tailwind skills • Comfortable improving an existing codebase • Can make practical UX decisions without needing everything spelled out • Good eye for healthcare / professional services design • Reliable communicator Tech stack • Next.js • React • Tailwind CSS • Supabase • Vercel • GitHub Deliverables • UX/design improvements implemented in the staging codebase • Responsive desktop/mobile polish • Clear commits or PRs • Brief notes explaining major design decisions

Given everything you've described, I wouldn't just hire another "web developer." I'd hire a **Senior Full-Stack Engineer** with experience taking over existing projects. That's a completely different skillset. Here's an Upwork posting I'd use: --- # Senior Full-Stack Developer (Next.js + Django + Stripe) – Take Over Existing Project We are looking for a **highly experienced senior full-stack developer** to take over an existing web application that was started by another developer. This is **not** a project for someone who needs hand-holding or is learning these technologies. We need someone who can quickly understand an existing codebase, identify what's complete, what's broken, what's missing, and efficiently finish the product. ## Tech Stack Must have professional experience with: * Next.js * React * TypeScript * Django * Django REST Framework * PostgreSQL * AWS * Stripe (REQUIRED) * Git/GitHub ## Stripe Experience (Required) You **must** have significant experience implementing Stripe, including: * Hosted Checkout * Payment Elements * Webhooks * Subscription billing * Customer portal * Refunds * Payment state management * Stripe Dashboard * Production deployments If Stripe is not something you've implemented multiple times, this is not the right project. ## Project The application is an online travel service with: * Multi-step customer application * Customer dashboard * Admin dashboard * User authentication * Payment processing * Email workflows * PDF generation * AWS deployment A previous developer has completed part of the project, but we need someone who can independently evaluate the codebase and finish the application correctly. ## Responsibilities Your responsibilities will include: * Review the existing codebase * Audit completed work against the original project scope * Identify missing functionality * Fix existing issues * Complete unfinished features * Improve code quality where necessary * Deploy production-ready code * Work directly with us during testing and revisions ## Important Our previous developer required a significant amount of frontend guidance and revisions. As a result, our team ended up recreating many HTML pages and UI components ourselves. We're looking for someone who can: * Take ownership * Ask questions before building when requirements are unclear * Build polished, modern interfaces without constant direction * Deliver production-quality work the first time Communication is extremely important. We'd much rather answer questions upfront than spend time rebuilding work later. ## To Apply Please include: 1. Links to **3 projects** you've personally built using Next.js and Django. 2. Describe your experience with **Stripe**, including subscriptions, webhooks, and payment flows. 3. Have you ever taken over another developer's unfinished project? Tell us about it. 4. How would you approach auditing an unfamiliar codebase before writing new code? 5. Your GitHub (if available). 6. Your hourly rate. 7. Your availability. ## Bonus Experience * AWS deployment * Sentry * Docker * CI/CD * PDF generation * Email automation * Travel platforms * Headless browser automation * Playwright
