Project details

A refactor of your existing database to provide complete referential integrity. Often developers "skip" creating proper referential integrity which can lead to invalid data and a poor database schema. I can create SQL statements to implement complete referential integrity or deliver a migrated database.  
Database Type MySQL, MS SQL, Oracle, SQLite, PostgreSQL

About Tom

Tom H A.
API Architect
100% Job Success
Salt Lake City, United States - 10:06 am local time
I have worked in PHP for over 23 years and can handle any PHP-related coding problem.

* My primary skill set and my focus in PHP is building complete API applications. I build GraphQL APIs with Laravel and Doctrine.

* I deploy my projects to Google Cloud where I have many years of experience. Building dev-ops for projects using Docker, Cloud Run, Cloud Functions, and more is a successful strategy I am adept at.

* I am an expert at Database Design and working with databases. I am a member of the Doctrine Core Team which produces the phenomenal Doctrine ORM project among others. I am sponsored by Skipper and create Entity Relationship Diagrams for any database I work with. I create migrations and fixtures for databases.

* I am skilled at reviving old databases through GraphQL and Doctrine. The existing database remains unchanged and a software ORM layer aliases the database for GraphQL endpoints.

* I am skilled with old code bases. I keep my skill set sharp and I've contributed to major frameworks, but my time in the field of PHP gives me unique experience with older code.

* I am React/Next.js literate and can work with a front-end team to build complex applications. I have worked with Angualr in the past.

I have over 150 open source projects I either own, am responsible for, or have contributed to.
