PROMPT ENGINEERING: Master AI Prompt Engineering with ChatGPT for Generative AI

In this course, I guide students step by step through the complete process of creating a detailed cyberpunk-style scene in Blender, starting from Blender’s default cube and ending with a fully rendered, cinematic environment. Throughout the course, I focus on solving the most common problems students face when learning 3D, such as understanding the full modeling workflow, fixing UV issues, adding realistic imperfections, and creating convincing lighting and atmosphere. Every step is recorded in real time, with clear explanations of not only what to do, but why it is done that way. By combining hands-on modeling, texturing, scene building, lighting, and post-processing, this course helps students gain confidence in their Blender workflow and teaches them how to turn a simple idea into a polished, professional-looking scene.

In this course, you will learn a complete CG and VFX workflow inside Blender by creating a cinematic Batman-inspired scene from start to finish. We begin by analyzing real movie footage from The Batman (2022) to build strong visual references for lighting, camera placement, and color grading. Step by step, you will learn how to block a scene, project camera footage, match CG with live-action, and smoothly blend both elements to achieve a cinematic result. Around 90% of the final scene is created in CGI, making this course ideal for learning how professionals combine live footage and CG efficiently. The course focuses on practical techniques, helping you avoid common beginner mistakes in lighting, camera matching, and post-processing. By the end of the course, you will have a complete cinematic shot and a solid foundation in Blender-based CG and VFX workflows that can be reused in your own projects.

This course is designed to help students confidently create large-scale landscape scenes in Blender without feeling overwhelmed by complex workflows. Throughout the class, I guide students step by step, explaining not only what to do, but why each decision is made. Common beginner problems—such as scene scale, camera placement, managing large environments, and shader complexity—are addressed clearly and practically. By breaking the entire process into manageable stages, students can follow along easily while still learning professional techniques used in real environment production. The course starts with Blender basics and gradually introduces more advanced concepts like volumetrics, shader mixing, photogrammetry assets, lighting, and compositing. My teaching approach focuses on clarity, real-world dimensions, and efficient workflows, ensuring students can recreate the process on their own and apply it to future projects.

This course is designed to guide beginners through a complete cinematic workflow in Blender, from the first idea to the final rendered scene. Drawing from practical production techniques, the course focuses on solving common beginner problems such as inefficient modeling, overcomplicating textures, and struggling to achieve realistic results with limited time. Each step is explained clearly and recorded in real time, showing not only what to do, but why it works. Students will learn how to create a visually rich cinematic scene using smart low-poly modeling, collage textures, efficient UV unwrapping, and emissive shaders. The course also covers lighting, environment creation, volumetrics, and scene composition to achieve a moody, cinematic look. By following a structured, step-by-step approach, students gain confidence in Blender while learning time-saving techniques they can reuse in future projects. Only Blender is required, making this course accessible and easy to follow for beginners.

This course is based on a real production workflow behind a Breaking Bad–inspired cinematic animation created and published on my YouTube channel. Instead of showing only final results, I focus on explaining every step of the process in detail, including the decisions, techniques, and problem-solving methods used during production. Many students struggle to understand how all parts of a cinematic scene fit together — environment creation, animation, lighting, assets, and final assembly. This class is designed to solve exactly that. Through a 4-hour in-depth tutorial, I guide you step by step through the creation of two full scenes, sharing practical techniques, common mistakes to avoid, and a clear production workflow you can reuse in your own projects.

In this course, I guide students step by step through the process of creating a procedural city generator in Blender using Geometry Nodes, and using it to build a cinematic Batman-inspired scene. The course is designed to solve one of the most common problems beginners face: understanding Geometry Nodes and knowing how to apply them in real projects. Instead of focusing on theory alone, I teach through a practical, beginner-friendly workflow, explaining every step and decision in a clear and efficient way. Students will learn how to model optimized buildings, create flexible Geometry Nodes setups, control lighting through shaders, and finally compose and render a complete cinematic scene. My goal is to help students not only follow along, but truly understand how to reuse these techniques in their own future projects.

This course is designed to help students move beyond theory and actually build real AI-powered marketing automation systems. Drawing from hands-on experience designing and implementing AI workflows, I focus on solving common problems students face—such as disconnected tools, repetitive manual tasks, inconsistent content creation, and lack of scalable automation. Rather than relying on abstract explanations, I teach through practical demonstrations and step-by-step workflows using n8n as the central automation platform. Students learn by building real marketing automations, AI agents, and multi-step workflows that connect ChatGPT, APIs, and business tools into reliable systems. By the end of the course, students don’t just understand AI automation—they know how to design, deploy, and orchestrate agentic AI workflows that solve real marketing problems efficiently.

This course provides a complete, concise, and practical introduction to Jira and Confluence for Agile project management. Based on real-world experience, I guide students step by step through setting up Agile projects exactly as Jira and Confluence were intended to be used. Throughout the course, I focus on solving the most common challenges beginners face: understanding Agile concepts, organizing backlogs, planning sprints, managing teams, and documenting work effectively. Instead of theory overload, I demonstrate clear workflows, real examples, and best practices that students can immediately apply in their own teams or organizations. By the end of the course, students gain the confidence to manage Agile projects, collaborate efficiently, and use Jira and Confluence as professional project management tools.

This course is built from real-world agile delivery challenges faced by Scrum Masters, Project Managers, and Product Managers who struggle with time pressure, unclear requirements, overloaded backlogs, and inefficient meetings. Through hands-on demonstrations and step-by-step workflows, I show students exactly how to use Generative AI tools—such as ChatGPT, Jira AI, Confluence AI, Rovo AI, and Fireflies.ai—to solve these everyday problems. Instead of theory, the course focuses on practical use cases: creating product goals, refining user stories, generating acceptance criteria, planning sprints, automating documentation, and improving team collaboration. Each lesson is designed to help learners apply AI immediately in their daily work, build confidence with industry-standard tools, and develop AI-powered habits that increase productivity, clarity, and leadership effectiveness in agile environments.
