designs in MySQL/PostgreSQL.

• Scripting \& Logic: Use Python for backend data processing, reporting scripts,

or integration tasks.2

• Modernization Strategy: Collaborate with the team to identify opportunities

where React components can be gradually introduced into the Ext JS

architecture.

• Engineering Excellence: Conduct code reviews, enforce TypeScript

standards, and ensure 80%\+ unit test coverage.

Required Qualifications (Must Haves)

• Experience: 5 to 7\+ years of full\-stack software development experience.

Preferred Qualifications (Good to Have)
