You will get Custom Client Portal with Auth, Documents, Approvals & Messaging Features
Project details
I'll build a secure client portal for your business — where your customers log in to see their projects, documents, status updates, and communicate with your team. Perfect for service businesses, agencies, consultancies, law firms, design studios, and construction companies.
Built on a SaaS-foundation stack so it's ready to multi-tenant later if you decide to productize it.
What you'll get:
• Secure login for clients + staff (JWT auth, role-based access)
• Client dashboard with project status, milestones, next steps
• Document management (upload, organize, view, sign-off)
• Approvals workflow — clients sign off deliverables
• Issue/comment tracking
• Messaging between client and your team
• Admin panel for managing clients
• Email notifications on key events
• Mobile-responsive UI
Tech stack: Vue 3 / Nuxt 3 (or React/Next), Node.js + TypeScript + PostgreSQL, S3-compatible file storage, deployable to Netcup/Hetzner (DE, GDPR) or Vercel + Supabase.

Job Success
Hannover, Germany - 4:32 pm local time
I'm a Senior SaaS Engineer specialized in subscription-based products, payment-heavy applications, and internal web tools. My goal: take over the entire technical side so you can focus on customers, sales, and growth.
What I help you build:
• SaaS MVPs and full products – multi-tenant web apps, dashboards, admin panels, customer portals
• Payment & billing flows – Stripe subscriptions, one-time payments, trials, upgrades/downgrades, invoicing
• Internal tools – booking & reservation systems, back-office dashboards, CRMs and automation for operations
• Integrations & workflows – REST/webhook APIs, 3rd-party SaaS integrations, background jobs and scheduled tasks
• Real-time features – live dashboards, notifications, collaboration features using WebSockets
Tech stack I work with:
• Backend: NodeJS (Express), TypeScript, REST APIs, webhooks, background workers
• Data: PostgreSQL, MySQL, Supabase (database, Auth, Realtime, Storage, Edge Functions)
• Frontend: Vue and Nuxt for modern SPAs and SSR apps, responsive UI, component-based architecture
• Payments: Stripe as the primary provider (subscriptions, billing, customer portal), with experience integrating other SaaS-focused billing platforms when needed
• Infrastructure: Docker and Docker Compose, Nginx, CI/CD (GitHub or GitLab), deployments to VPS and cloud (Netcup, Hetzner, AWS, Vercel and similar)
• Extras: Redis for caching and queues, email and SMS providers, analytics and monitoring tools
How I work with startups:
• Translate your idea into a clear technical architecture and roadmap
• Prioritize features for fast MVP launch while keeping the system scalable
• Build clean, maintainable codebases with documentation your team can understand
• Set up environments, deployments, and basic monitoring so your product is ready for real users
• Communicate clearly, give honest feedback, and treat your product like my own
If you're building or scaling a SaaS product and need an engineer who can own the complete lifecycle – from architecture and implementation to launch and iteration – I'd be happy to help.
