Freelance SQL developer in Ashburn, United States

Full-Stack CEO, Lean Startup Consultant, Super Genius, Force of Nature

A leader. A brother. (Possibly) Your secret lover. Also referred to as “Who was *that*?” or “What just happened here?”, Justice Gray is what would happen if a professional wrestler and a computer scientist had a baby, that baby married a hurricane and they had a child named Justice. He is passionate about Lean Startup principles and ideals, and Agile like a vast, predatory bird. Most importantly, he is a builder who loves to build: building applications, building teams, building businesses and building dreams. When he's not saving the world one company at a time, he can be found espousing his thoughts either on LinkedIn or at whoisjusticegray.com. Note: If you are looking for a much less prohibitively expensive - but possibly more talented and equally handsome - resource to singlehand...
Dave Sullivan, top SQL developerHire Now
Freelance SQL developer in Toronto, Canada

Full-stack Freelance Developer

I actually started with PHP and plain SQL statements with MySQL, then graduated to Django's ORM, so I'm comfortable with using SQL directly with or without an abstraction layer. Moved to Postgres about 4 or 5 years ago so I'm comfortable with that as well.

Richard McSharry, SQL dev and freelancerHire Now
Freelance SQL developer in Amsterdam, Netherlands

Freelance Software Guru (Angular5, Rails, SQL)

I understand RDBMS like Dumbledore understands magic. I can tune most SQL to make it faster. I understand joins, table scans, TNF, page tables, indexes, constraints, triggers, transactions, stored procs, views, functions, replication, failovers, clustering, mirroring, reporting, BI/analytics, data warehousing/olap. I've used a number of SQL databases and some NoSQL (like MongoDB and Redis) so my DB tech knowledge is quite broad in terms of which databases I've used. My strongest areas are SQL-Server, Postgres and designing databases, but also writing raw SQL.
Lucas Bertoni, top SQL developerHire Now
Freelance SQL developer in Ashburn, United States

Keep it simple :)

I have deep understanding on MS SQLServer insides and how to use it the best way. I know the perks of using mapping frameworks like EF and how to avoid performance issues. Most of people does not have the knowledge of how a database really works and how to use it to its most, sometimes we forget how powerful they are and end up with slower applications.

Weston Platter, senior SQL developerHire Now
Freelance SQL developer in Denver, United States

Fullstack Rails/Javascript Engineer

I rely on my intermediate SQL knowledge to efficiently and proactively manage database schemes. Indexes help keep queries fast, but N+1 can kill any optimizations because of poor app development decisions. I generally use an ORM. Here's an example of adding inner joins to eager load associations in with ActiveRecord/Rails, https://gist.github.com/westonplatter/6645878#file-double_nested_spree-rb-L18.
Michael Perrenoud, SQL freelancer and developerHire Now
Freelance SQL developer in Ashburn, United States

Enterprise application developer with 15 years of experience in the industry.

I've been building SQL Server applications for more than a decade now. I've built everything from static to fully dynamic schemas. I've even build pluggable schemas for applications that are modifiable by VAR's. I support applications that are accessed by hundreds of thousands of users across the country. These applications are proprietary in general but have shaped my experience over the years.
Billy Cravens, top SQL developerHire Now
Freelance SQL developer in Ashburn, United States

Ruby on Rails, Angular2, jQuery, DevOps on AWS, and more since 1999

I've been using SQL in many different databases to solve many different problems for a while. I experienced the pain of using Microsoft Access as a backend to ASP and ColdFusion applications back in the late nineties. I quickly moved to SQL Server, and have been working with it since version 7.0 (about 2000). Along the way, I've built several applications in MySQL, and in recent years, I've used Postgresql more and more. Most of the applications I've built required writing raw SQL, so I'm not hindered by a reliance on ORMs. I also have spent significant time in a DBA role, troubleshooting database installations, slow running queries, writing stored procedures and indexes, and more.
Charlton Wilbur, SQL software engineerHire Now
Freelance SQL developer in Spofford, United States

Software Engineer, Teacher, Explainer and De-Mystifier

I've been writing web applications backed by relational databases for over 20 years now; I'm only claiming 15 years, though, because it took me a while to get good at it. I have worked on small to medium applications (with data sets ranging in size up to a couple hundred gigabytes), and I have worked with architectures where the programmers were expected to write SQL pretty much directly, with minimal abstraction between the business logic application code and the database, and with architectures that had object-relational mappers or persistence layers between the business logic application code and the database. If you're working with highly database-specific optimizations and performance tunings, I probably can't help you much, since I'm not primarily a database administrator and I've ...
