Since 2010, the surveillance technologies of large companies as well as governments have considerably increased. Although you do not use any Google product and "refuse cookies", Google Analytics trackers are present on 90% of the websites and the sites you visit know your age, your browsing history as well as what time. you chat on WhatsApp, with whom and how often. These trackers form your digital footprint, in spite of you, and sell them. Your insurance, for example, can tell if you are expecting a baby in 9 months or if you develop signs of a chronic illness. I propose to teach you to: - Configure your phone and computer to use the Tor network, and protect yourself against surveillance. - How to use a VPN, which protocol to use and how to check if the VPN is monitoring you. - How to set up a kill switch so that the VPN does not leak and that the internet only works when the vpn is connected. - How to use a different operating system to stop monitoring Apple, Google and Microsoft. - How to pay on sites anonymously by purchasing prepaid credit cards with bitcoin. - How to anonymize your bitcoin - How to ensure that the government cannot afford to find you. - How to register on websites anonymously. - Buy Bitcoins (or other virtual currency) securely and anonymize them. I have worked for years with journalists, NGOs and companies to improve security and teach how to be anonymous in the eyes of big companies, malicious actors or even governments. Important: I do not teach courses on "how to make money with bitcoin", I only teach how to use it responsibly and the advanced protocols on which this system depends.

I teach Python specifically for finance and data applications - the kind used in economics, business analytics, and quantitative programs. This isn't a general "learn to code" course; it's built around real financial data, benchmarking, and the workflows you'll actually use in coursework or early career work. Topics include: Python fundamentals through a finance lens (data structures, functions, control flow). Working with financial data and datasets. Performance benchmarking and writing efficient code. Applying concepts from Hilpisch's Python for Finance.

You will learn Systematic Reasoning & Logical Thinking which is a requirement for entering Computer Science program in many universities. The book “Delftse Foundations of Computation” especially its second chapter will be the main source of our lesson, but other more in-depth books will be also covered if you want to improve even further on logical thinking. The topics in our lesson include: • Propositional Logic: Logical operators; Precedence rules; Logical equivalence; Implications in English; Exclusive or; Universal operators; Classifying propositions • Boolean Algebra: Substitution laws • Logic Circuits: Logic gates; Combining gates to create circuits; From circuits to propositions; Disjunctive Normal Form; Binary addition. • Predicate Logic: Predicates; Quantifiers; Tarski’s world and formal structures; • Deduction: Valid arguments and proofs; Proofs in predicate logic If you have any additional questions before starting a class, please feel free to ask me. I am here to assist! :)

Learn Python by building something you’ll actually use Ever wanted to code but had no idea where to begin? You’re in the right place. In these relaxed, one-on-one lessons, you’ll go from zero to writing real programs, with no experience required. Together, we’ll choose a project that fits your interests. Maybe it’s a video game you want to build or a quiz to challenge your friends, a chart built from your own spreadsheet, or a script that takes over a boring, repetitive task. Along the way, you’ll pick up the essentials (variables, loops, functions) and learn to read error messages without panic, so you can change your code with confidence. Where you can go next AI-assisted coding: Use tools like ChatGPT to brainstorm, decode errors, and improve your code, while learning to test its suggestions and explain how the final result works. Machine learning: Train a simple model on a real dataset and see how well it predicts. Your own project: Bring an idea from school, work, or a hobby, and we’ll break it into steps you can build at your own pace. Your instructor I’m an engineer with a master’s degree from Nagoya University and research experience in applied AI and computer vision. I explain every concept in plain language, then give you time to try it yourself with live feedback, so you’re never stuck alone. Ready to start? Send me a quick message and let's do your first coding project together.
