• Familiar with version control (Git), CI/CD workflows, and modern development tooling.
• Strong debugging and problem-solving skills - you can navigate ambiguity and find root causes efficiently.

• Write clean, well-tested, and performant code in Python, TypeScript, or other modern languages.
• Build and optimize APIs, data pipelines, and backend services that operate reliably at scale.
• Architect solutions that balance speed of delivery with long-term maintainability.
