Triplebyte is an online screening and recruitment platform for software engineers. It hosts some of the most talented freelancing webmasters on its platform thanks to its highly selective recruitment process.

Triplebyte searches for engineers in the top 1% when it comes to talent. Thus, costs for their services are higher and may not be affordable for smaller businesses and startups. However, their extensive hiring process is sure to promise that you receive quality work from their experienced users.

8. X-Team


X-Team


X-Team is unique in that it specifically hires freelance developers. If you require an experienced SQL developer, this is a good place to start. 


The hiring process freelancers must partake in to join the X-Team is rigorous and extensive. The company looks at past performance, resume and offers specific tests for the freelancer to accomplish. 


X-Team acts as a middle-man between you and the developers you aim to hire. Joining the employer network is as simple as inputting your information and describing the project you wish the freelancer to accomplish.


An X-Team manager will then look at your job description and search for a developer who meets all of your qualifications, eliminating the vetting process for you.


However, a few things to consider are that this site will expect higher costs than others. Additionally, X-Team has a required minimum for contracts. They prefer at least a three months work guarantee for their freelancers and favor longer projects.

9. Upwork


Upwork


Upwork is the largest freelancing platform to date, with over 14 million users. Similar to Fiverr, however, Upwork does not always guarantee quality freelancers. 


While the ample amount of freelancers offers a breadth of potential workers to choose from, it can be hard to know whether or not you will be signing on an experienced user who will deliver quality.


This is especially important to consider when searching for an SQL developer, as strategic topics such as developing and coding require some framework of expertise. Vetting the potential freelancers is equally challenging as there is no required testing for applying to or submitting a job.
