Tech migration support

Hi all, I’m in the final stages of acquiring a small e-commerce business and need help finding experienced technical support for the migration process. I’m looking to close here quickly. What I Need: • Python developer with FastAPI/Shopify API experience • Someone who’s handled similar SaaS/e-commerce migrations • Ideally available for 2-3 months (migration + stabilization) • Could be contractor, part-time My Questions: 1. Has anyone here managed a similar tech migration during an acquisition? 2. Know any reliable Python developers who specialize in e-commerce/Shopify? 3. What gotchas should I watch for in the handoff process? 4. Any recommendations for maintaining business continuity during the transition? The current owner has been cooperative with documentation, but I want to ensure I have the right technical expertise in place before taking over operations. Would appreciate any insights, referrals, or lessons learned from your own experiences! The Tech Stack: • Python/FastAPI backend with Celery workers • PostgreSQL database • Shopify integration (multiple stores) • API integrations • Some deprecated components needing updates
