I have expertise in designing efficient and scalable databases that can handle large volumes of data, including understanding normalization and denormalization techniques, indexing strategies, and database schema design. I can optimize queries to ensure fast performance by identifying slow queries and optimizing them through indexing, caching, or other techniques. I can also identify and implement a caching strategy to improve the performance of your application.
I also offer services in data modeling, database administration, and database migration. I can create a conceptual model of the data used in an application, identify entities, attributes, and relationships in the data, and design a database schema that reflects this model. I can administer and maintain the database, including tasks such as backup and recovery, performance tuning, and security management. I have experience in migrating databases between different platforms and environments, requiring knowledge of different database technologies and the ability to develop migration plans and scripts. I possess skills in working with NoSQL databases such as MongoDB, or DynamoDB, which are becoming increasingly important as more websites move towards distributed architectures and real-time processing.
