About Kofi


Bio

I’ve spent the last several years immersed in computer science, and I’ve built a strong foundation across both low-level and high-level programming. I specialize in languages like C, C++, Rust, and Zig because I enjoy the precision, performance, and problem-solving they demand. At the same time, I’m fully comfortable working in Python, Java, and R, especially for students who are learning programming fundamentals or exploring data-driven fields such as finance or machine learning.

I’ve spent the last several years immersed in computer science, and I’ve built a strong foundation across both low-level and high-level programming. I specialize in languages like C, C++, Rust, and Zig because I enjoy the precision, performance, and problem-solving they demand. At the same time, I’m fully comfortable working in Python, Java, and R, especially for students who are learning programming fundamentals or exploring data-driven fields such as finance or machine learning. My experience spans everything from core algorithms and memory management to object-oriented design and practical scripting.

A lot of my teaching ability comes from building things myself. I’ve created full web applications—front end and back end—using modern frameworks like React along with HTML, CSS, and JavaScript. I’ve also developed a wide range of personal projects, including a stock-trading backtesting engine, a machine-learning model for swing-trading equities, a Solana-based crypto token, several Minecraft mods, and an options-volume analysis tool designed to detect unusual activity or potential insider movement. These projects gave me real, hands-on experience with debugging, system design, API usage, and complex problem breakdowns, which I bring directly into my tutoring.

When I work with students, I focus on clarity, confidence, and genuine understanding. Whether someone is writing their very first Python script or digging into advanced C++ concepts, I help them think the way a developer thinks—breaking problems into manageable pieces, understanding why the code works, and learning how to debug instead of getting stuck. I’ve worked with learners of varying ages and skill levels, and I always adapt my approach to the student’s goals, pace, and learning style. My goal is to make programming feel approachable, intuitive, and even fun, so students not only improve their grades or projects but also gain skills they can build on far beyond our tutoring sessions.

Approved Subjects

C

C

I have extensive experience programming in C through building performance-critical systems focused on financial markets, cryptography, and low-level optimization. I developed a trading algorithm framework that analyzed market data in real time, identified trade setups, and evaluated risk to reward using custom indicators and signal logic, with a strong emphasis on memory efficiency and execution speed. In addition, I built a trade and options scanner that processed large datasets to identify volatility, pricing inefficiencies, and probability-based opportunities, requiring careful handling of data structures, numerical precision, and algorithmic efficiency. Beyond finance, I created a solana-based cryptocurrency in C that implemented core blockchain concepts, secure transaction handling, and heavy cryptographic primitives, including hashing, key management, and privacy-focused transaction design as a technical exercise in applied cryptography. I’ve also worked on additional C projects involving custom file parsers, low-level utilities, and performance-optimized tools that required debugging at the memory and pointer level. Through these projects, I’ve gained strong expertise in systems programming, algorithm design, and explaining complex C concepts.
Java

Java

I have hands-on experience programming in Java through developing multiple Minecraft mods using modern Java practices and APIs, which strengthened my understanding of object-oriented and event-driven design. Outside of game modding, I built a standalone Java command-line application designed to manage and process structured data, including reading from and writing to files. The project focused on modular class design, user input handling, validation, and clear separation of logic to keep the codebase maintainable. I’m comfortable explaining core Java concepts clearly, from syntax and data structures to debugging techniques and real-world application workflows.
JavaScript

JavaScript

I have hands-on experience using JavaScript to build real-world web applications and automation tools. I co-developed a full-stack project that used JavaScript on the frontend with React and Tailwind, and JavaScript-based logic integrated with backend services to automate business workflows and reduce manual work. This included handling user interactions, API communication, and improving conversion flow and performance. I’m comfortable teaching JavaScript concepts clearly, from core language fundamentals to practical frontend patterns and real project structure.
