American (native English speaker) living abroad. I teach people how to get projects built fast and become successful developers 🔥. I don't compete on price, but I do compete on quality, speed of training, and lack of a language barrier 🙂 **Free Resources** ▶️ I have a growing [YouTube channel](https://www.youtube.com/channel/UCPsi8tNv7UuNRljOTK5sl4A) where I cover popular requests I get. **Why Work With Me?** ⭐ More than 250+ 5 Star Reviews (see my [Wyzant profile](https://www.wyzant.com/match/tutor/87903194) too) 🗽 Native English speaker ✅ EXTREMELY responsive (from 10am to 10pm Portugal time) 💰 Successfully started and improved software dev careers for multiple clients. ⚪ Able to communicate complex topics simply ❤️‍🔥 Burning passion for coding and teaching 👁️ Can provide Process Maps for visual learners **Refund Policy** 💸 If I'm unable to help, you get a full refund. Easy 🙂 **Backstory** I started programming in 2018 after my mentor told me that it really fits the way I think. Before I started I was learning marketing, working in Facebook Ads and Shopify Stores (with Google Analytics, VWO, and other website optimization softwares), I was more interested in automation, and building to do tasks only once. I started at first learning Python for automation (which is still my primary language and what I really enjoy coding in). Eventually, I learned that by itself, Python isn't that sharable if you want other non-coders to use the my apps, so I grew my way into web development, diving deep into Django, HTML & CSS, building multiple sites with only those to get experience, for example: - My website: https://www.zackplauche.com/ - A mini app I built: https://www.dollarperhourcalculator.com And more :) Then eventually learning JavaScript and the Vue.js framework to take my websites, designs, and User Experiences to the next level, building at first simple apps like my DollarPerHour Calculator (https://zackplauche.github.io/DollarPerHourCalculator/), and more advanced ones, like the current one I'm developing (still in progress, but it's the biggest app I've ever build, using both Vue.js and Django). I've been teaching programming since 2019, and my students have loved me. I have students I work with that have been working with me weekly since I first started (more than 5 years now!). They helped me keep both my coding and teaching career sustainable as I was helping them with their issues, training them to be effective developers, starting my own software agency, and building my own apps. I'm extremely grateful to my students and truly care about and do my best to support their success in whatever their endeavors.

I define the architecture. For 21 years, I've been the person CTOs and lead developers call when systems fail under load, migrations are at risk or AI integration needs to work right the first time. With expertise in .NET, Python, Blazor, ASP.NET Core, SQL and agentic AI architecture (LLMs, reasoning engines, Semantic Kernel, LangGraph, tool-calling agents), I design systems where performance, reliability, and intelligent automation aren't optional—they're the baseline. I deliver AI in production, not prototypes. I’ve architected and deployed AI-powered systems across financial platforms, education and exam automation, and real estate market intelligence, including enterprise-grade solutions for organizations such as The New York Times, Project Management Institute (PMI), Walmart, Merit Wealth, Namfus and BlueberryCMS. --- **Here's where I'm most useful to you:** - **The AI Integration Trap** — You've been asked to add AI to your existing .NET system but don't know whether to use *Semantic Kernel*, raw OpenAI APIs, or a Python sidecar. I've made that decision dozens of times. I'll make it faster and safer for you. - **The Blazor Bottleneck** — Your Blazor app is slow, state management is tangled, and you're unsure if you chose *Server or WASM* incorrectly. I can diagnose what went wrong and map a clean path forward — often in a single session. - **The Legacy Modernization Cliff** — You have a 10-year-old .NET system that needs AI or modern tooling but wasn't designed for it. I specialize in *incremental refactoring paths* that don't require a full rewrite and don't break what's already working. --- **What I Do Best:** - **Software Architecture & System Design** — scalable, maintainable systems from greenfield to enterprise - **AI Agent Development** — production-grade agents with Semantic Kernel, LangGraph & AutoGen — *not demos* - **Blazor & ASP.NET Core** — Server, WASM, hybrid — full-cycle development and performance tuning - **Python & AI Automation** — RAG pipelines, workflow automation, voice AI, LLM integrations, chatbots - **Legacy .NET Modernization** — refactoring strategy, migration paths, incremental upgrades - **Architecture Audits** — identifying structural risk before it becomes a production incident, not after - **Debugging Complex Systems** — when the stack trace doesn't tell the whole story **If any of this sounds like your current situation — DM me. I respond to every message.**
