• Build backend services in Python and frontend applications in React;
• Design and maintain REST APIs, data contracts, and integrations with external systems;
• Build resilient systems (async processing, retries, fault tolerance);
• Contribute to the design system, reusable components, and Storybook;
• Use PostgreSQL, Temporal, Docker, and AWS Bedrock;
• Write tests, follow accessibility standards, and keep the UI maintainable;
• Investigate and fix bugs in production and in development;
• Add observability with OpenTelemetry and Grafana;
• Work with Terraform and GitHub Actions for CI/CD;
• Contribute to architecture decisions and help raise engineering standards;
• Use AI tools heavily to speed up design, coding, and troubleshooting — always with review and sound engineering judgment.
