As a seasoned tutor with a Bachelor of Science from the University of Minnesota, my expertise lies in guiding students through advanced mathematics and programming languages. I focus on helping students excel in AP Calculus (One, Two), college-level Calculus (One, Two, Differential Equations, Multivariable), and fostering a deep, comprehensive understanding of these subjects.

In Number Theory and Cryptography, I guide students through theoretical and practical aspects, including Applied Cryptography, Modular Arithmetic, Computer Security, and cryptographic algorithms like RSA, EL Gamal, Diffie Hellman, and Elliptic Curves. I aim to provide a complete understanding of how cryptographic tools are critical in securing digital communications.

My programming sessions, primarily in C++, cover topics from pointers and dynamic memory to advanced concepts like inheritance, templates, and data structures (Arrays/Strings, Linked Lists, Hash Tables, Stacks, Queues, Trees, Graphs). I emphasize scalable code, algorithm development, and practical testing environments. Additionally, I cover advanced C++ topics like design patterns, recursion, big-O, runtime analysis, and bit manipulation.

I also offer tutoring in Mathematical Logic, Numerical Analysis, and Linear Algebra, focusing on proofs, algorithmic methods, and matrix theory. I conduct sessions in R Studio for data science students, covering data analysis and statistical modeling. Additionally, I teach various programming languages, including C, SQL, Python, Bash, and Swift, catering to various interests and applications.

Since 2014, my teaching approach, honed at Mathnasium and as a computer science teaching assistant, focuses on cultivating problem-solving skills, discipline, and responsibility. At "Mapping Our Thoughts," I create tools that supplement and reinforce these fundamental principles in our tutoring lessons.

C

C

As a TA for C/C++ at the University of Minnesota, I focused on core concepts like pointers, structs, memory allocation, segfaults, and memory management. I guided students through debugging with tools like GDB and Valgrind to analyze how programs behave under unexpected conditions, emphasizing real-world applications such as cybersecurity and finding software vulnerabilities. In founding companies, I applied these skills to build secure, efficient software solutions, specializing in code testing, performance optimization, identifying bottlenecks, and refactoring code to prevent exploits, all with a strong C/C++ foundation.
C++

C++

During my time as a TA for C/C++ at the University of Minnesota, I focused on core concepts like pointers, structs, memory allocation, segfaults, and memory management. I guided students through building essential data structures such as binary trees, graphs, sets, B-trees, hash tables, linked lists (both singly and doubly linked), arrays, and vectors, often using tools like GDB and Valgrind to debug and analyze how each structure behaves under different conditions. We explored recursion and dynamic programming, emphasizing Big O notation to understand efficiency. In founding companies, I applied these skills to build secure, efficient software solutions, specializing in code testing, performance optimization, identifying bottlenecks, and refactoring code to prevent exploits, all rooted in a strong C/C++ foundation.
Calculus

Calculus

With 10+ years of experience, I can help you understand core topics like limits, derivatives, the product/quotient rule, chain rule, related rates, and optimization. I also cover advanced techniques such as implicit differentiation, trigonometric substitution, integration, u-substitution, and sequences/series. Beyond the basics, I dive into higher-level topics like Newton's and Euler's methods, parametric equations, polar coordinates, and Taylor/Maclaurin series. Whether you're tackling Calculus 1, 2, AP Calculus AB/BC, or Business Calculus, I can guide you through it all and ensure you're prepared for success.

Holding a Bachelor of Science degree from the University of Minnesota, my tutoring expertise is deeply rooted in Computer Engineering. Since 2014, I have been providing in-depth guidance in this field, focusing on advanced programming, data structures, and algorithms. My teaching includes specialized topics like sorting functions (Quicksort, Mergesort, Bubble Sort, Selection Sort), search algorithms (DFS, BFS), multithreading (semephores, threads), and bit manipulation, essential for a strong foundation in Computer Engineering. Alongside these, I delve into systems design, basic circuit theory, and digital systems, ensuring a comprehensive understanding. My sessions also cover programming languages such as C/C++ and Python, with a strong emphasis on their practical application in real-world scenarios. This balanced approach prepares students for academic excellence and equips them with skills vital for professional success in the dynamic world of Computer Engineering.
Cybersecurity

Cybersecurity

I am a lead researcher at Mapping Defense focused on cryptography and applied cybersecurity, and I tutor both undergraduate and graduate courses. I routinely help with DES and AES (S-boxes, Feistel structure), block cipher modes (CBC/CTR/GCM), public-key cryptography (RSA, ECC, Diffie-Hellman), digital signatures, hash functions (SHA-2/SHA-3), and MAC/HMAC. For problem sets and exams, I break down modular arithmetic and number theory (modular exponentiation, Euler's totient, extended Euclidean algorithm), finite fields GF(2^n), modular inverses, the Chinese Remainder Theorem, padding (PKCS#1/PKCS#7), PKI, and proof-style reasoning into clear, step-by-step solutions. I also cover shellcode basics (BASH), assembly vs C/C++, buffer overflows and exploit analysis, memory safety (stack/heap), and system auditing, always with an ethical, defense-first approach.
Swift

Swift

With my C/C++ background, I’ve tested and built secure Swift apps for the Apple App Store, ensuring high performance and security. I’ve developed productivity apps, focusing on managing state, event-driven programming, persistence, and asynchrony for efficient software. Using SQLCipher for encryption and managing app signing in Xcode, I ensure data protection and smooth App Store deployment. My approach emphasizes reusability, modularity, and design patterns for scalable, maintainable apps.

Antonio is simply the best tutor I've ever worked with! Don't bother with anyone else.

Antonio helped with a very difficult C++ programming class. Without his help, I'm not sure I would have passed the class. He helped me to understand complicated structures and classes and objects. He helped make programming fun!

Looking for an incredible tutor? Antonio is your guy!

After working with Antonio for three sessions, I took a test in my computer architecture class. For the first time this semester, I felt confident walking out. If you need help in a CS class, he's the best!

Knowledge and patient

I highly recommend Antonio. I have been going to him for two years now and can say my grades have definitely been positively affected through his help. I originally was struggling badly in a linear algebra class I took last year and had extremely low homework grades and was worried about my upcoming exam. Within only a week of tutoring I ended up getting a 96 on that exam with the help of Antonio. Ever since I have heavily trusted him to be able to effectively help me understand material I struggle with. I am currently still going to Antonio and am still getting the same amazing results through his help. He is also very kind, patient, and will go at whatever pace is good for you.
