This is a high-autonomy, high-responsibility role with broad ownership of the modernization effort.

• Build production-ready FastAPI services.
• Define migration architecture and strategy to gradually replace the legacy monolith.
• Improve CI/CD maturity and implement robust deployment practices, including rollback-safe deployments.
• Strengthen infrastructure reliability and operational procedures.
• Document architectural decisions and maintain clear technical documentation.
• Collaborate with a small team to ensure smooth migration and production stability.

• Strong Python experience with production systems.
• Proven experience with FastAPI in a production setting.
• Strong MySQL knowledge (schema design, indexing, query optimization).
• Comfortable in Linux (Ubuntu) command line.
• Experience with pytest for testing.
• Git Hub and Git Hub Actions CI/CD experience.
• Experience deploying behind Nginx or Apache.
• Docker experience.
• Professional use of VS Code or similar IDE.
• Understanding of API design and system decoupling.

Nice-to-have:

• Ability to read Perl code and participate in modernization of monolithic systems.
• Experience with Google APIs, Stripe or other payment systems.
• Basic React experience (for internal admin tools);
  React is not a primary frontend requirement.
