At DataArt, I'm moving a business travel management platform from Angular 1.5 to React 18 while maintaining high-availability backend services. I also migrated Sabre endpoints for train search and reservations without downtime.
At Parser Digital, I built cloud-based backend services and a billing and subscription system for a healthcare provider, using .NET Core, MySQL, AWS, and Terraform. I also developed React and TypeScript interfaces and integrated secure authentication.
At SOUTHWORKS, I contributed to multi-cloud serverless systems and streaming applications. I implemented a Node.js middleware pattern for AWS and Azure storage, using TDD with Jest to achieve over 90% code coverage.
