We host the best tutors. Quality of their profile, experience in their field. Leon will be happy to arrange your first lesson Computer programming.

About the lesson

Beginners:
My job is to give you the tools to approach programming problems yourself, a key to programming is a strong foundation in how the basic building blocks of software work. We can assess where you currently are and build up from there. Whether we are starting with variables and assignment, or implementing ADTs from scratch, I have a set of examples you can take away with you and work on from the very first lesson.

Students:
My role is to help you with building a clean and easily maintainable code base with proven architectures. We will set a good foundation by first looking at what dev environment you use, how to manage builds and automate testing and how you can get the most out of your development setup.

We will approach theoretical problems through worked examples, making sure that you aren't just memorising words, but learning the implementations behind them. We will approach labs and projects by taking small steps and making sure to build in comments so you can look back at your work and recall later on for revision.

Career Changers:
Many of my students are looking to make a change or just add software and data science knowledge to their current skillset. I've built games, REST API's and simulations with students, helped clarify parts of online courses and provided direction for those who wanted to get into the field but weren't sure where to start.

If any of the above are you, let me know and let's start!

I usually conduct my lessons via Google Meet, I try and send a link via the Superprof messaging app well before the lesson starts so you can get everything set up and ready without too much stress.

About Leon

I am a DS and AI student with 6 years experience in instructional techniques and management and over 400 hours of tutoring CS, Data Structures, and Software engineering. Having returned to academic study after a 6 years of work, I understand the struggle of following a course that may be too quick, have poor lecturers or assume a lot of knowledge, and I am here to help!

I have experience working in: Java, Python, MATLAB/Octave, C, git, BASH, docker, SQL, numpy, keras, pandas and work with both Unix and Windows OS.

Leon's response
Really enjoyed working with Johnny, clearly a very talented mathematician who has set his sights on software, I'm certain he will succeed in breaking the Python syntax barrier and hope that our next lessons give him the tools to speed up his progress.

Perfect! I appreciated Leon's teaching methods. He was concise yet thorough, and helped me to recall basic implementations and usages of data structures. I also appreciated his explanations, use of drawing out a problem before coding, and asking me to explain my understanding and planning of a problem. It was a combination of getting back to basics while prepping for interviewing through clear communication. Thanks Leon!

Had a great first lesson with Sylvia! She has very good foundational Java knowledge and given her ability to quickly assimilate new information we were able to cover a great deal in one session. Looking forward to the next one!

Perfect! So far, I have had a few sessions with Leon and he is extremely knowledgable, friendly and patient. He explains data structures in simple terms and whiteboards the concepts and implementations, which really helps to make data structures less elusive. Moreover, the sessions encourage talking out and breaking down a problem before coding, which is a skill I am glad to be developing. Look forward to continuing on with sessions.

Perfect! I have had three lessons with Leon so far. Being quite new to programming and in the middle of a Master's degree, things can get overwhelming quite quickly. Leon is always professional and patient and makes sure I understand fully each point before moving on to the next. More than just showing you the tools, he teaches you to think differently and to break down each problem to their core which in turns makes tackling the problem and coding it easier. I look forward to each lesson and start to feel more confident with what I learn! Thank you.

Leon helped me with my java projects and assignments. He helped me with coding efficiently and solving problems easily. He has his own style to deal with problems. He splits problem s into sub-problems which helps you to understand it easier. He shared his experiences and notes which helped me a lot when I struggled with something. He always does his best and his best is more than enough! I personally strongly recommend Leon if you have problems with java and general problem analysis.

Sir Leon is an outstanding friendly teacher. His lessons are very productive, very engaging and I learn a lot in an hour. I have learnt new techniques in working out which makes it easy in maths. I find it very easy to understand his method. In the first lesson itself, he recognised my weak area and helped me to progress. I'm sure I will excel in maths learning with sir Leon. I have learnt math with couple of teachers but Sir Leon is the best. I would highly recommend him.

Instead of providing a first free lesson, I keep my prices well below similarly qualified tutors in my subjects. I do this to reward the students who have stuck with me for many lessons, rather than having them subsidise newcomer's first lessons. I hope you understand.
