Fast Affordable Server Migration for Fintech

I need an experienced infrastructure engineer to help me move my Fintech application off its current host and onto a server stack that is both noticeably faster and cost-efficient. My priorities are low-latency transaction handling, high uptime, and a predictable monthly bill. I am open to any major cloud vendor—LINUX, AWS, Google Cloud, Azure, or an equally robust alternative—provided the final choice can give me the best mix of performance and price.

Here’s what I expect:
• A short cost-vs-performance comparison of the leading options, with clear reasoning for the recommended platform.
• A detailed migration plan that avoids downtime for end users.
• Full execution of the migration, including configuration of security groups, autoscaling, backups, and monitoring.
• Post-migration performance testing to verify faster response times and system stability.
• Concise hand-over documentation so I can maintain the new environment confidently.

If you have a track record of moving production workloads—especially Fintech or similarly regulated apps—and are comfortable with tools like Docker, Kubernetes, Terraform, and CI/CD pipelines, I’d like to work with you.
