What is a Freelance Full Stack Developer job?

A Freelance Full Stack Developer is a self-employed professional who builds both the front-end and back-end of websites or applications. They work with various technologies, including databases, servers, APIs, and client-side interfaces, to create fully functional digital products. Unlike full-time employees, freelancers work on a project basis for multiple clients, offering flexibility in workload and schedule. Their responsibilities often include coding, debugging, deployment, and sometimes design.

What types of projects and clients can Freelance Full Stack Developers typically expect to work with?

Freelance Full Stack Developers often engage with a diverse range of projects, including website and web application development, e-commerce platforms, mobile app backends, and API integrations. Clients can range from startups and small businesses to established companies and entrepreneurs seeking bespoke digital solutions. The variety in clients and project scopes allows developers to constantly expand their skills and work experience, but it also means adapting quickly to new industries and client expectations. Freelancers typically manage their own workflow, communicate directly with clients, and are responsible for project timelines, making this role ideal for self-motivated technology professionals.

What are the key skills and qualifications needed to thrive in the Freelance Full Stack Developer position, and why are they important?

To thrive as a Freelance Full Stack Developer, you need a solid grasp of both front-end and back-end programming languages (such as JavaScript, HTML/CSS, Node.js, Python, or similar) and a strong portfolio showcasing completed projects. Familiarity with frameworks like React or Angular, version control systems like Git, cloud services, and sometimes relevant certifications (such as AWS Certified Developer) are highly valued. Excellent communication, problem-solving abilities, time management, and client relationship skills help set freelancers apart. These competencies are crucial for effectively delivering end-to-end solutions, managing multiple projects, and building a reliable client base.

Job description

Are you the kind of developer who enjoys building modern solutions while untangling complex legacy systems?

We’re looking for a Web & Systems Developer who thrives in environments where no two days look the same, someone equally comfortable working across backend systems, APIs, databases, LMS integrations, and front-end experiences.

This is an opportunity to join a highly collaborative, education-focused organization that supports large-scale digital learning initiatives across Ontario. You’ll play a key role in modernizing web applications, improving online learning experiences, and helping evolve systems that directly support students, educators, and healthcare professionals.

???? Who You Are

  • A strong full-stack developer who enjoys both problem-solving and building
  • Someone comfortable working across legacy and modern web environments
  • Curious, adaptable, and eager to learn new technologies quickly
  • Experienced with backend/frontend data flow and API integrations
  • Able to work independently while collaborating closely with cross-functional teams
  • Someone who enjoys wearing multiple hats instead of being siloed into one narrow area
  • A developer who values stability, flexibility, and meaningful work

???? Work Type

  • Location: Ottawa, Ontario (Hybrid – must be willing to meet at least 1 day per week to collaborate with the team)
  • Vacancy Type: This role is a newly created position

Requirements

???? What You’ll Do:

  • Develop and maintain full-stack web applications supporting e-learning and academic systems
  • Build and maintain integrations between internal platforms and Canvas LMS using APIs
  • Support and enhance online course delivery systems and student learning tools
  • Modernize and maintain legacy applications and internal platforms
  • Design and develop database-driven applications, reporting pages, and administrative tools
  • Work with MySQL databases, backend services, and production environments
  • Support WordPress website redesign and modernization initiatives
  • Troubleshoot production issues, system bugs, and integration challenges
  • Develop automation scripts and workflow enhancements for academic operations
  • Collaborate with educators, administrators, and technical teams to improve digital learning experiences
  • Support ongoing system migrations, modernization efforts, and platform enhancements
  • Contribute ideas, technical recommendations, and process improvements across the development lifecycle

⭐ What We’re Looking For:

  • 4+ years of full-stack web development experience
  • Strong hands-on experience with PHP development
  • Proficiency in JavaScript, HTML, CSS, and responsive web development
  • Experience working with SQL databases and backend/frontend data flow
  • Experience building and maintaining RESTful API integrations
  • Experience supporting and maintaining production web applications
  • Ability to work independently and manage multiple priorities effectively
  • Experience with MySQL, jQuery, and backend integrations
  • Exposure to IIS and/or Linux server environments

Nice-to-Have:

  • Experience with ColdFusion (Lucee) would be considered an asset
  • Experience with LMS platforms such as Canvas, Moodle, or Brightspace is considered an asset
  • Experience with WordPress or similar CMS platforms is beneficial
  • Previous exposure to e-learning, higher education, or healthcare environments is a strong advantage
  • Bilingualism (English/French) is considered an asset

Benefits

  • Base Salary: $80,000 - $95,000
  • Paid Time Off: Competitive vacation and personal days to help maintain a healthy work-life balance
  • RRSP matching: Employer-matching retirement contributions to support your long-term financial goals
  • Health & Wellness Benefits: Medical, dental, and vision benefits to support your overall well-being
