Cómo contratar a un excelente Xojo Developer freelance

A Xojo developer is a software engineer who builds cross-platform desktop, web, mobile, and Raspberry Pi applications using the Xojo programming language and integrated development environment. Hiring a freelance Xojo developer gives you access to specialised talent capable of shipping native apps for macOS, Windows, Linux, iOS, Android, and the web from a single shared codebase.

Xojo programming has a loyal following among independent software vendors, scientific software houses, and internal tools teams precisely because it removes the cost of maintaining separate codebases per platform. A skilled Xojo programmer translates that efficiency into faster delivery, fewer bugs, and software that feels native on every target device.

What a freelance Xojo developer delivers

A Xojo developer writes object-oriented code in the Xojo IDE and compiles it to native binaries for desktop, web, iOS, Android, and Raspberry Pi targets. The output is a working application, source project files, and supporting documentation that your team can maintain.

Common deliverables include:

Cross-platform desktop applications for macOS, Windows, and Linux compiled from one Xojo project file

Web apps built with Xojo Web for internal dashboards, customer portals, and line-of-business tools

iOS and Android mobile applications built from the same shared classes and modules

Database-driven applications connecting to PostgreSQL, MySQL, MariaDB, Microsoft SQL Server, Oracle, or SQLite

REST API integrations using Xojo's URLConnection and JSONItem classes

Custom controls, subclasses, and reusable modules packaged as Xojo plugins

Migration of legacy Visual Basic 6, REALbasic, or Real Studio projects to current Xojo releases

Bug fixes, performance tuning, and code refactoring on existing Xojo codebases

Build automation, code signing, notarisation, and installer packaging for each target OS

Tools and technologies a Xojo programmer uses

Strong candidates work fluently across the Xojo toolchain and the surrounding ecosystem your application will touch in production. Look for hands-on experience with:

The Xojo IDE, Xojo Cloud, and the Xojo debugger across desktop, web, iOS, and Android targets

Xojo's framework classes, including Window, WebPage, MobileScreen, Thread, and Xojo.Net.HTTPSocket

Database engines such as PostgreSQL, MySQL, SQLite, and Microsoft SQL Server through Xojo's database plugins

Third-party Xojo plugins from vendors like MBS (Monkeybread Software), Einhugur, and GraffitiSuite

Source control with Git, including Xojo's text-based project format for clean diffs

REST, SOAP, JSON, and XML for backend integrations

Code signing for macOS, Apple notarisation, Windows Authenticode, and platform-specific installer tools

Adjacent languages a Xojo developer often touches, including SQL, shell scripting, AppleScript, and occasional C or Objective-C for declares

Industries and use cases

Xojo is widely used wherever small and mid-sized teams need to ship native software without the overhead of separate iOS, Android, Mac, and Windows codebases. Typical projects on Freelancer.com include:

Scientific and laboratory instrumentation software, including serial port and USB device control

Manufacturing, logistics, and warehouse management tools running on Windows shop-floor PCs

Healthcare and clinical record applications with strict offline and database requirements

Education software, classroom utilities, and assessment tools for macOS and Windows

Independent software vendor (ISV) products distributed through the Mac App Store and direct download

Internal business tools, ERP front-ends, and inventory systems for small and medium enterprises

Raspberry Pi applications for kiosks, signage, and industrial control

How to evaluate Xojo developer candidates

Because the Xojo community is smaller than mainstream language communities, portfolio evidence and direct technical questions matter more than certifications. Look for these signals:

Several years of consistent Xojo or REALbasic experience, ideally with shipped applications you can download or screenshot

Evidence of cross-platform builds, not only one operating system

Database experience with the engine your project will use

Familiarity with code signing and notarisation if you plan to distribute publicly

Clean, modular project files with proper class hierarchies rather than monolithic event handlers

Comfort working with Git and the Xojo text project format

Useful interview questions to copy and use:

Can you walk me through a Xojo project you shipped to both macOS and Windows, and the platform-specific issues you had to solve?

How do you structure long-running tasks in Xojo to keep the UI responsive, and when would you use Thread versus Timer versus async network calls?

Which database engines have you connected to from Xojo, and how do you handle prepared statements and transactions?

How do you sign and notarise a macOS Xojo build, and what is your Windows installer process?

Have you migrated legacy REALbasic or older Xojo projects to a current Xojo release, and what breakage did you have to fix?

Why hire Xojo developers on Freelancer.com

Freelancer.com gives you direct access to a global pool of Xojo developers, from independent consultants who have shipped commercial Xojo products to generalist software engineers maintaining internal Xojo apps. Because Xojo is a niche skill, the breadth of talent available on Freelancer.com matters: you can compare candidates from multiple regions and time zones rather than settling for whoever is local.

Clients set their own budgets and receive competitive bids from freelancers on Freelancer.com, with profile ratings, written reviews, and portfolio samples on every developer's page. Milestone Payments hold funds in escrow until you approve each stage of work, so you stay in control whether you are commissioning a new cross-platform application or hiring for ongoing maintenance.

Ready to ship cross-platform software without maintaining separate codebases? Post a project on Freelancer.com today and connect with skilled Xojo developers ready to build, migrate, or maintain your application.

What are the steps to hiring a freelance Xojo developer?

Hiring a Xojo developer works best when your brief reflects the niche nature of the skill. The clearer you are about target platforms, Xojo version, and existing code, the more accurate the bids you will receive. The process below walks you through posting, reviewing, and awarding the project.

Step 1: Post your project on Freelancer.com

Your project post is the single biggest determinant of bid quality. A clear, technically specific brief filters for Xojo developers whose experience genuinely matches your needs and discourages bidders who only know adjacent languages. Head to the post project page , where you fill in the brief, scope, timeline, and budget before publishing the project for freelancers to bid on.

The Xojo version you are targeting (for example, Xojo 2024 r1 or later) and whether you can supply the project file

Target platforms required: macOS, Windows, Linux, iOS, Android, web, or Raspberry Pi

Database engine and any existing schema, plus expected data volumes

Third-party plugins already in use (MBS, Einhugur, GraffitiSuite) or that you are open to purchasing

Distribution requirements such as code signing, Apple notarisation, Mac App Store submission, or Windows installer creation

Timeline, milestones, and whether you need ongoing maintenance after launch

Step 2: Review bids from freelancers

Bids are short proposals, not just price quotes. A strong Xojo developer will reference your specific platforms, ask about your Xojo version and database, and propose a realistic build sequence. Read each proposal carefully and shortlist candidates whose understanding of the work matches your brief.

Clarity on how the developer will structure classes, modules, and shared code across platforms

Sensible questions about Xojo version, plugins, deployment targets, or legacy code you mentioned

A realistic timeline broken into milestones rather than a single end date

References to specific Xojo framework classes, plugins, or database engines relevant to your project

Sample work attached or links to shipped Xojo applications you can inspect

Use Freelancer.com's chat to ask clarifying questions about debugging approach, code signing, or testing strategy before shortlisting

Step 3: Evaluate freelancers and award the project

The final decision combines proposal quality with profile evidence. Look at portfolio depth, written reviews from previous clients, and consistency across past Xojo work rather than a single impressive screenshot. For a niche skill like Xojo, repeat clients and long-running maintenance engagements are particularly strong signals.

Portfolio depth across multiple Xojo applications, ideally on more than one operating system

Star ratings combined with the volume of completed projects, not ratings alone

Written client reviews that mention reliability, code quality, and communication

Verified payment method and identity verification on the freelancer's profile

Completion rate, on-time delivery rate, and response times

Award the project to your chosen Xojo developer and use Freelancer.com's Milestone Payments to release funds only as each agreed deliverable is approved

How long does a Xojo development project take?

A small utility or internal tool can be built in one to two weeks, while a full cross-platform commercial application with database integration and code signing usually runs several months. The biggest variables are the number of target platforms, database complexity, and whether you need iOS and Android builds in addition to desktop.

Can I hire a Xojo freelancer for a one-off bug fix or small change?

Yes. Many Xojo developers on Freelancer.com take on short maintenance jobs such as fixing a crash, adding a feature, or recompiling a legacy project against a current Xojo release. Provide the project file, a clear description of the issue, and the target operating systems when you post the brief.

What is the difference between Xojo and Visual Basic or REALbasic?

Xojo evolved from REALbasic and Real Studio and shares syntactic roots with Visual Basic, but it is a distinct, actively developed language with modern cross-platform compilers for desktop, web, iOS, Android, and Raspberry Pi. A Xojo developer can often migrate older REALbasic or VB6 projects, but expect refactoring rather than a clean import.

Do I need a Xojo developer or a general cross-platform developer?

If you already have a Xojo codebase, hire a Xojo developer to keep the project consistent and avoid a costly rewrite. If you are starting from scratch and have no Xojo investment, discuss the trade-offs with candidates before committing to a stack.

Can a Xojo developer build mobile apps as well as desktop?

Yes. Xojo supports iOS and Android targets alongside macOS, Windows, Linux, web, and Raspberry Pi, and experienced Xojo developers can share business logic and database code across all of them. Confirm mobile experience specifically, since some Xojo developers focus on desktop only.
