What is the Full-stack developer stack at Mate academy?

Frontend (HTML/CSS/JS/React/Redux/TS) + Backend (Node.js, Express, REST API, PostgreSQL, MongoDB) + DevOps basics. 900 hours, the broadest stack on offer.

Is there demand for junior Fullstack developers in Poland?

Yes, especially in startups and smaller product companies. Large corporations prefer narrow specializations. Fullstack gives more flexibility on the junior market.

Frontend vs Fullstack: which to choose as a beginner in Poland?

Frontend — faster path to a job (650h, more offers), but competitive. Fullstack — longer study (900h), fewer junior offers, but more flexibility and adaptable career.

How much does a Full-stack developer junior earn in Poland in 2026?

Junior Fullstack: PLN 6,000–9,000 gross + VAT (B2B) or 7,500–11,000 net. Mid (after 1–2 years): PLN 16,100. You can apply to FE, BE, and FS roles.

Why does Mate academy teach Node.js, not Python/Java for backend in Fullstack?

One language (JS) for the whole stack — easier FE↔BE switching, most popular in PL startups, fastest start. Python/Java are separate courses.

What is REST API and why is it taught in the Fullstack course?

Topic:API

Answer:

REST API is the standard for exchanging data between client and server over HTTP. A junior Fullstack must both build APIs (Node.js) and consume them from Frontend (React).

REST (Representational State Transfer) is an architectural style for building APIs over HTTP: GET/POST/PUT/DELETE methods, JSON in request/response, stateless interaction. It is the de-facto standard in web dev — 90%+ of products communicate between frontend, backend, and third-party services through REST. A junior Fullstack must handle both sides: consume APIs (on Frontend — fetch, axios) and build their own (on Backend — Express endpoints, validation, authorization). Mate academy teaches both directions through practical projects and the Team Project, where one student is Frontend and another is Backend. Plus an alternative: GraphQL (overview) as a new trend. Without REST API a junior will not pass a technical interview — it is the foundation of backend knowledge (source: NoFluffJobs 2026).

Thanks to Mate academy, after a previous unsuccessful attempt to enter the IT industry, I managed to find a job within 30 days of completing the course. A wealth of knowledge, support from mentors and assistance in conducting recruitment interviews are three of the many advantages that Mate academy offers on a new career path

What can I say about Mate academy? Theoretical and practical preparation at the highest level. But in my opinion, this is not the main advantage of this course - the advantage of this course are mentors who are convinced of your success and support you at every stage of your activity. Through learning practice, understanding theory, practicing soft skills, support in job search and related aspects.

I recommend this course to people who want to enter the world of IT and don't know where to start. There is a lot of knowledge on the Internet, which is beneficial, but at the same time it can be confusing for a beginner. At Mate, you get a defined learning path waiting for the motivated student. Additionally, the help of mentors, test tasks and code reviews drive development and allow you to get your first job.
