    I have 9+ years of Swift and 12+ years of Objective-C experience. I've worked as an engineering lead for the past 5 years as both a contractor and full time employee. In 2018 I published my first book on Swift Playgrounds titled "Simulations in Swift", which has now been picked up by Apress. I write articles for the popular Ray Wenderlich/Kodeco website on Server Side Swift, run a YouTube channel teaching Swift development and mentor at a local university. I am the author of several popular Swift libraries including FaceAware and SimpleCheckbox. I write clean, and well tested code for highly polished projects, but also know when to hack things together for quick prototypes and proof of concepts. I've built apps for iOS, Mac, Apple TV, Apple Watch, and I even have significant Server Side (Vapor) experience as well as programming and integrating with embedded systems. If you're looking for a high quality product, with a slick user interface, smooth animations, and is easy for future devs to maintain, choose me!

How much does it cost to hire a freelance Bluetooth developer?

Bluetooth developers help create useful applications and hardware solutions to connect users with their devices, share information, and ease access to many modern systems. While Bluetooth applications initially linked computers and mobile devices, they have expanded exponentially to all sorts of systems such as gaming, healthcare and wellness, payments (PayPal and Stripe), geolocation, and social media. 

Bluetooth is also utilized in wearables (smartwatch notifications), home appliances, smart homes/buildings, smart lighting, and even systems that track a business’s assets, employees, or visitors. 

It was Bluetooth technology that originally facilitated wireless connections for both mobile and stationary devices over short distances for purposes of data transmission or to create wireless networks. 

Bluetooth also links computer peripherals (such as a printer, speakers, or a mouse), enables real-time voice and data transmissions (data, video, image, and music files), and serves as a networking device between Bluetooth-enabled devices (laptops, notebooks, PCs, mobile phones, personal digital assistants, and smartwatches). 

The expense of hiring a freelance Bluetooth developer depends on several factors. It’s important to have a detailed description of your mobile app development project, including your preferred attributes and your ultimate app along with your projected budget. Determine whether you need native apps—both a Google Android app and an Apple iOS app—for better performance, or if a less expensive cross-platform app would be adequate.

Knowing many of these factors ahead of time makes it easier for your prospective Bluetooth freelancer to accurately determine whether their skills fit your project, how much time it will take, and if you have reasonably budgeted for your app ambitions. Developing Bluetooth mobile applications can cost anywhere from $2,000 into the tens of thousands of dollars.

If you are unclear or lack the technical savvy to develop a plan up front, a more experienced freelance Bluetooth developer may be better able to help you find the right solution for a high-quality app.

Experience and expertise 

Bluetooth developers need to have expertise in various programming languages such as Java, JavaScript, and Swift (along with frameworks such as Angular, Flutter, and React). A strong knowledge of APIs (application programming interfaces), hardware/software compatibility, connection processes, and security considerations are essential. 

Hiring a Bluetooth freelancer on Upwork can cost anywhere from $25 to more than $100 per hour, depending on experience, versatility, location, and project skills. But rates are heavily influenced by the level of expertise and location.

Scope of work

The complexity of your Bluetooth applications will affect the experience you need in your developer and the cost. The user experience (UX) is critical for Bluetooth apps. Many things can go wrong when establishing Bluetooth connections between devices, and the complexity of developing most Bluetooth-driven apps should not be underestimated.

Entry-level freelancers, often the low-cost option, might be fine for simpler apps. Intermediate- to expert-level Bluetooth freelancers with multiple years of experience bring greater skill sets, including project management and product development. 

These complex interactive applications often require critical decision-making up front and difficult bug fixes later. They also cost more, though their experience likely makes them more efficient and better able to adequately troubleshoot inevitable problems with Bluetooth development.

Timeline 

With most freelancers charging an hourly rate, more complex projects can become very time intensive and expensive. More experienced developers, while more expensive, could minimize your development time and heartache in the long run. Consider your budget and project complexity. Then strike a balance between cost and experience as necessary.  

Geography 

Location will have a significant effect on the rate that a Bluetooth freelancer will charge. For example, a developer in a large coastal city with a high cost of living is likely to charge more than one in a small city in the Midwest. 

Freelancers are most expensive in North America and Western Europe, while contractors in Eastern Europe, Latin America, and many Asian markets often charge far less. Evaluate during interviews the possible effects of communicating with offshore developers, both in terms of time lag and language skills.

Popular Bluetooth related systems  

Health and wellness

Bluetooth apps can connect your phone or smartwatch to monitor and facilitate workouts, link to fitness equipment, track your performance, and monitor aspects of your health. 

Smarthomes

Bluetooth enables home automation systems such as lights, heating and cooling, appliances, and security systems to be controlled from a smartphone. 

Connected in the car

Bluetooth for both Android and iOS has become as common as power windows in new cars. It links to your phone to enable hands-free calls, narrate and listen to text messages, play music, and link to your navigation system.
