AWS Developer for Database and Lambda Optimization

I’m looking for an experienced AWS developer to review and safely update an RDS MySQL 8.0 database and three Lambda functions using Python 3.8. The work includes improving performance, ensuring reliability, and identifying unnecessary AWS charges to reduce ongoing monthly costs. You should be able to assess the current setup, recommend practical optimizations, and implement changes with minimal disruption. Experience with database and serverless environments is important, along with a strong focus on cost efficiency and system stability.
