Senior platform migration engineers in Barcelona run roughly $69–$99/hr. 3K–8K seniors; usually one cloud deep (AWS dominant). 4–6 week senior hiring loop. Operating timezone: CET/CEST (UTC+1/+2).
2026 migration: AWS DMS, Google Database Migration Service, Azure Database Migration for cross-cloud DB; Liquibase or Flyway for schema; Apache Kafka or Debezium for change-data-capture during cutover; feature flags (LaunchDarkly, Statsig) for gradual user migration. Senior migration engineers handle dual-write patterns, replay-and-replay-safe ETL, validation tooling, and the inevitable rollback plan. A migration without a tested rollback is not a migration — it's a hope-driven cutover and the cause of every "we lost 30 minutes of orders" disaster.
Where Barcelona senior platform migration talent comes from: Barcelona senior talent flows from Glovo HQ, Wallapop, eDreams ODIGEO, Telefónica Barcelona, plus UPC + UPF + UB CS programs. Mobile + travel-tech + e-commerce depth. MWC (Mobile World Congress) annual hosting effect. For platform migration specifically, this means buyers can typically tap engineers who have shipped at one of these orgs before — relevant operational depth, not bootcamp graduates.
Our platform migration team delivers a full range of capabilities tailored to Barcelona's Mobile & Telecom and Travel Tech sectors:
Migrate your WordPress site to a blazing-fast Next.js application with better performance, SEO, and developer experience.
Rebuild aging PHP,.NET, or Java applications in modern stacks like React, Node.js, and TypeScript.
Migrate from Magento, WooCommerce, or custom carts to Shopify, Shopify Plus, or headless commerce setups.
Move on-premise infrastructure to AWS, Azure, or GCP with proper architecture, security, and cost optimization.
Migrate between database systems — MySQL to PostgreSQL, MongoDB to SQL, or legacy databases to modern alternatives.
Move content between CMS platforms — WordPress, Drupal, or Contentful to headless CMS like Payload, Sanity, or Strapi.
Each phase ships with written progress notes plus a weekly review call scheduled in your business hours. See our full process →
When choosing a platform migration partner in Barcelona, look for a team with production experience in your specific industry. Generic developers miss critical domain nuances that cost you time and money in rework.
