Nektarios Chazirakis

I’m a Principal Software Developer working on large-scale web applications for the maritime industry, and I also build and run my own B2B SaaS platform end to end. My day job is the same thing I’ll be teaching you: writing real, maintainable code that people actually use.
That shapes how I teach. I know which parts genuinely confuse beginners, and I don’t assume you already know the jargon.

What I can teach:
HTML, CSS and JavaScript from the ground up; TypeScript; Angular; working with databases and cloud services (Firebase); Git and version control; and the professional habits that separate hobby code from employable code — testing, structure, code review, debugging.

Who I work with:
Complete beginners of any age, school and university students who need help with coursework or projects, and adults considering a career change into tech who want an honest picture of what the work actually involves.

How I teach:
We build something real from lesson one. I’ll explain the concept, then we write code together, then you write it yourself while I’m there to unstick you. Sessions are hands-on, at your pace, with practice work between lessons if you want it. Lessons available in Cardiff in person or online, in English or Greek.
