Learn Arduino, robotics and electronics one to one with a qualified electronics engineer who teaches this at university level. Complete beginners through to degree students, online worldwide or in person in Birmingham, with a free 30 minute introduction before you book anything.

I'm Ghous. I hold an MSc in Electronics and Electrical Engineering with Distinction from the University of Chester, where I teach as a Visiting Lecturer on a Master's module, and I work as a freelance engineer designing circuit boards and writing embedded firmware for clients. I have taken a four layer ESP32 board from schematic to manufactured hardware, built the electrical power system for a CubeSat, and published two international conference papers on running neural networks on microcontrollers. When you ask why your sensor reads nothing or how to justify a design choice in a report, the answer comes from doing this work rather than from a tutorial.

Adults and hobbyists

If you own an Arduino kit and have stalled, or you can copy a project but cannot change it, this is the gap I close. We build what you actually want, home automation, data logging sensors, motorised builds, a device that talks to your phone, and underneath it you pick up the real skills: reading a datasheet, using a multimeter, wiring safely and debugging when nothing happens. No technical background required.

University and college students

Embedded systems, microcontrollers, robotics, control systems, circuit analysis and digital electronics. Arduino, ESP32, nRF52, PIC with MPLAB and STM32, plus Proteus, Multisim, Webots and PCB design in KiCAD. I also supervise final year and Master's projects from scoping through to the write up. I mark Level 7 work myself, so I know where reports lose marks. I teach students on UK, IB and continental European programmes and have worked with engineering students in Germany, so an unfamiliar syllabus is not a problem. Send me your course material and I will work from it.

School students, ages 9 to 18

Beginners who want to build something real, and students with coursework in Design and Technology, Computer Science or Engineering, whether on GCSE, A Level, IB or a national curriculum. Typical builds are a line following robot, an obstacle avoiding car, a live weather station or a motion triggered alarm. For lessons in Birmingham I bring all the equipment. Parents are welcome to sit in on the first session (UK DBS checked).

How lessons run

Tell me your level and what you want to build, or send your assignment brief, and I plan the session around it before we meet. I demonstrate first, then you take over while I guide, because nobody learns electronics by watching. Online students share a screen and I debug code and wiring photos live. Every session ends with something working and a clear next step, and you can message me between lessons.

Lessons run over Google Meet or Zoom, 60 or 90 minutes. I teach across GMT and Central European time with evening and weekend slots. Online students can start with any board they already own, or I will point you at one starter kit under 30 euros that covers the first several months.

Message me with your level and what you are trying to build and we will arrange the free 30 minutes.

Hello,

After a 34-year career in systems engineering (including roles as AVP System Engineer & Product Owner at Moody's), I've learned one essential truth: technology is useless if it remains overly complex.

There is NO set curriculum or pre-defined syllabus: every session is 100% tailor-made. I adapt entirely to your request, your skill level, and your current objectives—whether that means gently discovering a new tool or solving a specific technical challenge.

My approach is built on clear, accessible guidance: no unnecessary jargon, no dull theory, and no prerequisites required. My goal is to make technology accessible, seamless, and immediately useful (if my experience helps you avoid a few costly surprises, then I’ve done my job).

Examples of what we can cover together:

Discover and Master AI (ChatGPT, Copilot, Claude, Gemini, Veo, etc.)

Learn how to write clear prompts to get accurate results (prompt engineering).

Use AI to draft content, summarize documents, analyze data, or organize your daily work.

Understand best practices to use these tools securely.

Simplify and Automate Your Daily Tasks

Connect your collaborative tools (emails, files, calendars, M365 services) to eliminate repetitive actions.

Migrate to new M365 services smoothly.

Set up simple virtual assistants to save you time.

Optimize Your Digital Tools & Cloud Environment

Take control of your IT workspace, organize collaborative environments, and secure your access.

How?
We start with YOUR topics: a practical problem to solve, a project to bring to life, or a tool you want to master. Everything is explained clearly and patiently so that you leave every session with practical, actionable solutions.

Whatever your starting point or project, the course adapts to you—never the other way around.

This course is aimed at beginners and students who wish to understand web cybersecurity in a practical, progressive and structured way.

The goal is not to learn techniques by heart, but to understand how a web application works and how to reason when faced with a security problem.

We will be discussing, in particular:

• the basics of HTTP: requests, responses, methods, cookies and sessions;
• Authentication vs. Authorization;
• Getting started with Burp Suite Community;
• Broken Access Control;
• IDOR and BOLA;
• horizontal and vertical privilege escalation;
• roles, permissions and ownership;
• Security API basics;
• bug bounty methodology;
• drafting a clear vulnerability report.

The exercises are performed in dedicated learning labs, CTFs, or explicitly authorized environments.

My method is based on a simple line of reasoning:

Actor → Action → Object → Expected Authorization

Each session alternates between explanations, demonstrations, practical exercises with Burp Suite and guided correction.

The program can be adapted to the student's level, from the discovery of Web cybersecurity to the first methodologies of BAC/IDOR vulnerability research.
