Senior DevOps Engineer for Webflow Migration, DNS & Traefik Setup

We are looking for an experienced DevOps / Infrastructure Engineer to help us launch a new Webflow website while maintaining our existing production infrastructure. Current setup Our domain (ranked.de) currently points to a Load Balancer / Traefik setup. Historically, multiple services were routed through the same infrastructure: - Main website - CRM / Application - WordPress blog The website was integrated into the application infrastructure by a previous developer, which makes the migration more complex than a standard Webflow deployment. Goal We have already built a new website in Webflow and want to launch it on: https://ranked.de The blog is not relevant for this phase and can remain offline. Requirements: - Launch the new Webflow website on ranked.de - Keep the existing CRM/application operational - Configure DNS, routing and proxy setup correctly - Minimize SEO impact and downtime - Support the go-live process Challenge A simple DNS change to Webflow would currently break access to the CRM/application because both systems depend on the existing infrastructure. We therefore need someone who can: - Review the current architecture - Recommend the best migration strategy - Implement the required DNS and routing changes - Ensure a smooth production launch A possible approach could be: - ranked.de → Webflow - app.ranked.de → CRM However, we are open to your recommendation after reviewing the setup. Required experience - DNS management - Reverse proxies - Traefik - Load balancers - Docker - Linux servers - Webflow hosting - Production infrastructure migrations Proposal requirements Please briefly explain: 1. Relevant experience with similar migrations 2. Your recommended approach 3. An estimated timeline 4. A fixed-price proposal We prefer a fixed-price project rather than hourly billing.
