My Story

Hello — I'm Collen

I'm a full-stack web developer based in Pretoria, South Africa. I build websites and digital products that help businesses grow online—combining clean code, modern tech, and a focus on what actually works for users and clients.

My path into development started with a curiosity for how things are built on the web. That led me from the basics—HTML, CSS, JavaScript—to full stack work with React and Node.js, and to delivering real projects for South African businesses.

  • Custom websites & full-stack web apps
  • Android app development
  • UI design & front-end implementation
  • Technical consulting & ongoing support

Background

I grew my skills step by step: front-end first, then back-end, then tying them together into full stack applications that solve real business needs.

01

The start

Learned HTML, CSS, and JavaScript, then moved on to React for the front end and Node.js for the back end. Built a solid base in both client-side and server-side development.

02

Full stack delivery

Started building and shipping full web applications with React, Node.js, Express, and databases—RESTful APIs, auth, and deployments that scale for real use.

03

Where I am now

I focus on full stack projects with modern tools, working with businesses that need reliable, scalable web solutions and clear communication along the way.

Experience

I'm a full-stack web developer and digital marketer with experience across the stack and in working directly with businesses.

Technical skills

I build modern, responsive sites and web apps with HTML, CSS, JavaScript, React, Node.js, and related tools. I care about accessibility, performance, and keeping code maintainable.

Client work

I've worked with South African businesses to deliver full stack applications that solve real problems—from idea to launch—with a focus on what the business and its users actually need.

Full stack projects

Built and launched multiple web applications with React, Node.js, and current best practices—focused on UX, performance, and real business value.

Portfolio & delivery

Delivered responsive websites, web apps, and digital solutions for clients, with an emphasis on clean code and architecture that can grow with their needs.

What Sets Me Apart

I don’t just write code—I make sure the solution fits your goals, your users, and your timeline, and that it can be maintained and improved over time.

Trusted by founders, agencies, and small businesses looking for a reliable technical partner.

Clear communication

I keep projects on track with straightforward updates and no jargon. You’ll know what’s happening at each stage and what to expect next.

End-to-end ownership

From design and development to deployment and support, I take responsibility for the full project so you get a solution that’s built to last.

Business-minded

I focus on outcomes: performance, usability, and scalability that align with your business objectives, not just technical checkboxes.
