RELEVANT PROJECT EXPERIENCE • Configured HTTPS for a custom domain on AWS S3 and Amplify. • Helped recover a website affected by a ransomware incident. • Set up a password-protected private application on a DigitalOcean VPS. • Delivered AWS support, server optimization, email configuration, and Linux server rescue work. A CAREFUL APPROACH TO PRODUCTION SYSTEMS Before significant changes, I review backup and rollback options. During the work, I provide clear progress updates. After implementation, I check the affected services and document the changes and recommended follow-up. For troubleshooting, send the symptoms, hosting platform, and relevant error messages. For migrations or new deployments, share your current setup, target environment, and timeline. I will help define the scope and a practical plan.
