Every engineering team runs on Git, yet most students meet it as a pile of half-remembered commands. This course builds the three-area mental model (working tree, staging area, repository) and then layers the skills you will actually use daily: clean commits, branching and merging, pull requests, remotes and forks, stash and cherry-pick, bisect, hooks and reflog recovery.

Short lessons, real command sequences, and a final exam with certificate eligibility. Free forever — Git is infrastructure for your whole career.

**Who this is for:** first-years through final-years in every branch, and anyone about to join a team that uses GitHub.

**What you need:** a machine with Git installed (or a GitHub account to follow along in the browser).

From first commit to confident collaboration — snapshots, branching, PRs, hooks and disaster recovery

Git & GitHub Mastery

Every product has a web interface, and every product team needs people who can build one properly. This bootcamp covers the foundation the frameworks assume you already know: semantic HTML, the CSS box model, flexbox and grid, modern JavaScript with the DOM, accessible forms, REST API integration and a performance workflow with the browser DevTools.

Eight lessons across four modules. Every lesson follows the nine-step structure: objective, hook, concept, worked example, practice, common mistakes, the exam angle, a server-graded quiz and a one-screen summary. A 30-question bank feeds a 15-question timed final exam; passing earns a verifiable TieEdu certificate.

**Who this is for:** students who have copied tutorial code but cannot yet build a page from scratch, and anyone preparing for a junior frontend interview. The course deliberately teaches the platform (HTML/CSS/JS) before any framework, so React or Vue later becomes an acceleration rather than a crutch.

**What you need:** a browser and a text editor. A free hosting account (GitHub Pages, Netlify or similar) is recommended for the project so you finish with a live URL, not just local files.

HTML, modern CSS, JavaScript, forms, APIs and performance — the frontend stack every product team hires for

Web Development Bootcamp

Linux shows up everywhere: lab machines, cloud VMs, CI runners and almost every backend interview. This course teaches the shell you actually use — navigation and permissions, the grep/sed/awk pipeline that beats any GUI for logs, processes with kill and systemd, packages, SSH and network checks, then enough bash to automate the boring half of your day.

Eight compact lessons, each with a worked example you can type along, a practice prompt and a server-graded quiz. Finish with the timed final exam and a verifiable TieEdu certificate.

**Who this is for:** first-years who have only used Windows, placement candidates facing Linux rounds, and anyone deploying a project to a cloud box for the first time.

**What you need:** any Linux sandbox, WSL, or a free cloud VM. Commands are written so you can also follow along on a school lab machine.

Navigate the filesystem, filter text like a pro, manage processes and write your first real bash scripts

Linux & Shell Basics

Every software role — backend, data analyst, full-stack, even ML engineering — screens with SQL. This course takes you from writing a first SELECT to designing normalised schemas, choosing indexes that actually get used, reasoning about transactions, and using window functions for the analytics queries that appear in real take-home tests.

Eight lessons across four modules. Every lesson follows the nine-step structure: objective, hook, concept, worked example, practice, common mistakes, the exam angle, a server-graded quiz and a one-screen summary. A 30-question bank feeds a 15-question timed final exam; passing earns a verifiable TieEdu certificate.

**Who this is for:** any student or working developer who wants SQL to be a strength rather than something to google under deadline pressure. Campus OA database rounds, analyst interviews and backend screens all draw from the same pool of patterns taught here.

**What you need:** basic programming familiarity helps but is not required. A free PostgreSQL or MySQL instance to practise on is recommended — these are not spectator topics.
