    I have designed and maintained hundreds of databases for a variety of businesses and orgaizations. I specialize in FileMaker development, having been a FileMaker Developer since version 2.1 ( I currently develop and support all versions through 2023). I am experienced in designing databases for business, for both stand-alone and multi-user installations. For many businesses, I have designed a single database to replace the use of multiple programs that required duplication of data entry (as well as duplicating their labor cost). I customize my applications to your business and your style of working. My database designs often include document retrieval and Internet functionality. Your database can be strictly for in-house use, or accessible via the Internet. I have accumulated a broad experience in both hardware and software in over 3 decades within the computer industry. I have been self-employed since 1983, and understand the needs of a business owner and employer. I have worked with many different industries, including: medical / healthcare, retail, finance, non-profit, education, construction, and manufacturing. I have experience in understanding the various needs of these different organizations, and will perform the same for you and your business or organization. A partial list of my previous FileMaker applications: Direct Sales/Service Customer Relationship Management (CRM) for a direct sales and service company. System designed for use by in-office employees, remote employees, and salespeople / service technicians in the field (mobile devices). Maintain prospect / customer records; create filtered lists for telemarketing, marketing campaign management; create scheduled appointments for sales and service; email/text message generation for marketing, employee and customer notifications; Internet integration for mapping, research and tracking; reporting for inventory / sales / payments / customers / etc. Retail Point-of-Sale Maintain prospect / customer records; generate and store quotes / orders / invoices; inventory management; customer document retrieval for pictures / PDF documents / Word & Excel files / etc.; email generation for marketing and customer notifications; Internet integration for mapping, research and tracking; reporting for inventory / sales / payments / customers / etc. Rental Point-of-Sale Maintain customer records; generate and store rentals / orders / invoices; inventory management; customer document retrieval for pictures / PDF documents / Word & Excel files / etc.; email generation for marketing and customer notifications; reporting for inventory / rentals / payments / customers / etc. Finance Company / Service Bureau AutoBilling Maintain customer records; generate invoices for each account automatically based on the billing frequency (monthly, quarterly, semi-annually and annually) and customized for each Vendor to insert the correct graphic logo at the time of printing; customer document retrieval for pictures / PDF documents / Word & Excel files / etc.; email generation for marketing and customer notifications; Internet integration for mapping, research and tracking; reporting for accounts / dealers / billing / payments / collections / histories / etc. Medical Case Logger Designed for use by Radiology Technicians at a hospital destroyed by Hurricane Katrina. The technicians employed web browsers to access a web-published database for a radiology group. The technicians created case records of the patients that the Radiologists diagnosed, and automatically produced reports for the Radiologists three times per day. The database was also accessed via the Internet by transcriptionists. On a monthly basis, an invoice for services performed was created automatically with a fully detailed log of each case. Patient Record Retrieval Developed for well-established surgical practice that maintained paper records and charts for their patients. Data imported from the medical billing application generated Patient records to expedite the search and retieval of decades of medical records. Magazine Subscription Manager Maintained subscription records for multiple magazines and newspapers published by a sports and cultural publisher. Generated reminders and reports of expiring subscriptions for marketing and billing. Service Company Manager Maintained customer records for a chimney sweeping company to store important details about each customer's account, including site surveys, services performed, future services, and service technician notes. Data was originally exported to Palm Pilot PDAs, and currently accessible by smartphone or tablet through Internet web publishing. The system also produces management and billing reports for the company, and links customer records to Internet mapping sites for directions to customer addresses.

How to Hire Top Database Administrators

What is a database administrator?

Database administrators are tasked with ensuring that data analysts can effectively use a given database for the purpose of storing and retrieving information. Additionally, an administrator’s role typically involves maintaining the integrity and functionality of a database and making sure it works properly for those who use it. 

How do you hire a database administrator?

You can source database administrator talent on Upwork by following these three steps:

  • Write a project description. You’ll want to determine your scope of work and the skills and requirements you are looking for in a database administrator.
  • Post it on Upwork. Once you’ve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
  • Shortlist and interview database administrators. Once the proposals start coming in, create a shortlist of the professionals you want to interview. 

Of these three steps, your project description is where you will determine your scope of work and the specific type of database administrator you need to complete your project.

How much does it cost to hire a database administrator?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced database administrator may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their database administrator services more competitively. 

Which one is right for you will depend on the specifics of your project. 

How do you write a database administrator job post?

Your job post is your chance to describe your project scope, budget, and talent needs. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.

Job post title

Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample database administrator job post titles:

  • Need help creating and maintaining company database
  • Looking for Microsoft SQL database expert
  • Microsoft Access genius needed to convert Excel data into Access

Project description

An effective database administrator job post should include: 

  • Scope of work: From Access programming to building automatic queries, list all the deliverables you’ll need. 
  • Project length: Your job post should indicate whether this is a smaller or larger project. 
  • Background: If you prefer experience with certain industries, software, or platforms, mention this here. 
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

Database administrator job responsibilities

Here are some examples of database administrator job responsibilities:

  • Manage all database responsibilities, including development, staging, and production environments
  • Restore service to databases as outages occur, including after hours and on weekends
  • Perform technical analysis and troubleshooting to resolve complex database problems

Database administrator job requirements and qualifications

Be sure to include any requirements and qualifications you’re looking for in database administrator. Here are some examples:

  • Excellent written and oral communication skills
  • Undergraduate or technical degree in computer engineering or computer science
  • Minimum of 5 years proven SQL server-database experience
