AWS

I work with cloud infrastructure in production every day as the technical co-founder of a consulting firm, with my primary platform being Google Cloud and meaningful hands-on experience with AWS for personal projects and client work. Because AWS and GCP share the same underlying concepts (compute, object storage, managed databases, serverless functions, IAM, VPCs), I can help you build strong intuition for how cloud services actually work, which makes certification prep and real-world deployments far less intimidating. I am best suited for students preparing for AWS Cloud Practitioner or Solutions Architect Associate, professionals trying to understand cloud architecture conceptually, and anyone deploying their first real project to AWS. If you are debugging a deep, niche AWS production issue, I am happy to do a free intro call first to make sure I am the right fit.

Computer Science

I hold a Bachelor's in Computer Science from The George Washington University and recently completed my Master's in Cybersecurity at NYU's Tandon School of Engineering, where I have also served as a Teaching Assistant in the graduate cybersecurity program. In that role I support graduate-level coursework, hold office hours, and work one on one with students to help them connect theoretical concepts to practical scenarios. Outside of NYU, I am the technical co-founder of a digital consulting firm where I designed and built our production platform from scratch using PostgreSQL, Node.js, and Google Cloud, which gives me real-world context to bring into every tutoring session. My tutoring approach is grounded in the belief that most students get stuck not because the material is too hard, but because it was first introduced in a way that skipped the context they needed. I focus on building intuition before drilling syntax or memorization. For cloud and infrastructure topics, that means starting with what problem each service actually solves before opening the console. For cybersecurity, it means understanding the attacker's perspective before memorizing controls. For programming and CS coursework, it means writing small things that work before scaling up. I have worked with adult learners, career changers, and graduate students, and I am comfortable adjusting my pace and depth depending on whether someone is preparing for a certification exam, working through a class assignment, or trying to apply a concept at their job. I tutor remotely and offer a free 15 minute introductory call before any paid session so we can confirm I am the right fit for what you are working on. My goal is for you to leave each session with something concrete you understand and can use, not just a recap of what your textbook already said.

Cybersecurity

I hold a Master's in Cybersecurity from NYU's Tandon School of Engineering, where I also serve as a Teaching Assistant in the graduate cybersecurity program, including coursework on mobile and wireless security. I recently earned my CompTIA Security+ certification, so I can speak directly to the current exam objectives and the kinds of scenario questions that trip students up. I am best suited for students preparing for Security+ or working through undergraduate and graduate cybersecurity coursework on topics like cryptography, network security, access control, risk management, secure software development, and security operations. My approach focuses on understanding the attacker's perspective and the why behind each control, which makes the material stick well past the exam.

Machine Learning/ AI

I use AI tools like Claude and ChatGPT every single day to run my consulting firm, where I have built production AI workflows including a sales assistant that handles client outreach, a lead generation scorecard, automated research and writing pipelines, and integrations between AI and our customer relationship platform. I bring that direct working experience into every session rather than teaching from textbooks or someone else's tutorials. I am a strong fit for working professionals, founders, small business owners, and career changers who want to learn prompt engineering, build their own chatbots and assistants, set up retrieval-augmented generation, or figure out exactly how to apply AI to their specific job or industry. I am not the right fit for students working through classical machine learning coursework involving neural network math or model training in PyTorch, and I am happy to do a free intro call first to make sure we are aligned.
