NYC based developer with 16+ years of experience (independent freelancing, at Fortune 500s and at small startups). Languages include PHP, Javascript, Python, and Java. I have framework experience with Laravel, Symfony, CodeIgniter, and Vue. Always up for a challenge, whether it's new development or tracking down a bug. I enjoy overall architecture as much as getting into the finer details.

I am **US-based** and have **30+ years experience** during which I have been an AI user, a software engineer, a programming trainer, a marketer and an entrepreneur. My current focus is in **long term tutoring** professional in using **AI**, **software development**, and/or **CI/CD DevOps** Specifically: 1. I specialize in teaching **Claude Code** to non-developers who want to build software 1. I specialize in **Go** and **Bash** but can handle any language; e.g. Python, TypeScript, etc. 2. I love **API**s and can teach you how to call them with command line Bash tools 3. I can teach you how to write API **servers** in Go, and also how to call APIs in Go. 4. I have 25+ years in **SQL** and can teach SQLite, MySQL, or Postgres 5. I can teach you to configure **macOS** and **Linux** for programming 6. I can teach **CI/CD** with **GitHub Actions**, Jenkins, GitLab, or others 7. I can teach using **Docker** containers and/or how to build them 8. I can how to write **Kubernetes** controllers and operators in Go 9. I can teach you how to work with **Digital Ocean** or basics in **AWS**. I can also teach you many other things. While I don't use Windows daily, I have used it in the past and am familiar with PowerShell and Windows System for Linux so I can help with those if need be. ALSO, I am great at learning on the fly so if you are interested in me helping you learn something I have not listed I will consider giving a discount for topics that allow me to learn new things while teaching, especially related to AWS.

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.**
