About Callum
I’m a professional software engineer with experience leading space mission software development and a strong academic background in Computer Science from the University of Southampton. My work includes satellite communication protocols (e.g., CFDP as used in the JWST), real-time operating systems (RTOS), and embedded Linux (Yocto, drivers, BSPs). I’ve mentored junior engineers on-the-job and helped students improve coursework, projects, and exam results for a range of topics up to A* grade.
Who it’s for:
- Early-career engineers preparing for embedded/software interviews (aerospace, defence, or finance roles)
- University students in Computer Science or Electronics
- A-Level students needing support in Computer Science or systems topics
- Anyone with a curiosity for how software meets the real world

️About My Lesson
I take a clear, structured approach to tutoring that’s focused on building deep understanding and confidence — not just passing exams. Whether you're learning C programming for the first time, tackling an embedded systems assignment, or preparing for a technical interview, I’ll tailor each session to your level and goals. My teaching style is calm, practical, and hands-on. I break down complex topics into manageable steps, and I like to use real-world examples wherever possible — especially from my experience working on European Space Missions and embedded Linux systems.
I believe in understanding why things work, not just how to memorise them. ️
Typical lesson format:
60–90 minutes (depending on preference)
Mix of explanation, worked examples, and live problem-solving
Optional takeaway exercises or project review if desired
Topics I often cover:
- C programming fundamentals: memory, pointers, structs, call stacks
- Embedded systems architecture: scheduling, ISR, memory-mapped I/O, driver design - RTOS concepts: task priorities, watchdogs, deadline misses (e.g., RTEMS, FreeRTOS)
- Linux for embedded: init systems, file systems in RAM, startup flow, Yocto
- Space software: TM/TC, CCSDS, FDIR strategies, safe mode design
- Testing & reliability: ISVV concepts, fault injection, testing and debugging in embedded environments
- Project/code review support: feedback on university or personal projects across a range of languages
- Interview prep: walk-throughs of low-level questions, design problems, or CV reviews
- University / A Level Computer Science Topics
Whether you want to improve your grades, debug a project, or develop industry-level skills, I’m here to help.

Perfect! Callum is an outstanding tutor and I can’t recommend him highly enough! He’s incredibly patient, explains concepts clearly, and takes the time to make sure you truly understand the material. Even complex topics become much easier to grasp with his detailed explanations and supportive teaching style. If you’re looking for help with programming or embedded systems, Callum is a fantastic choice. A truly great tutor!
- Sean is a great student, very easy to get along with and very motivated to learn. Very excited to continue working with Sean for future lessons.Callum's response :
