🤖 Working with AI daily? Check out my copy/paste prompt collection for developers: dev-chatgpt-prompts — 10 stack-agnostic prompts ready to paste. No fill-in-the-blanks, no setup.

Senior Fullstack Developer with 11+ years of experience building robust, scalable systems across healthcare, finance, real estate, and supply chain domains. Specialized in AI/LLM integration, modern full-stack development, and comprehensive test automation.

Core Philosophy: "Serenity as Strategy" — transforming uncertainty into structured action through calm, traceable processes where AI suggests but humans decide. Autonomous, resilient, and visionary with a proven track record of delivering consistent value under real-world constraints.

Recent work spans applied AI/LLM systems in production (RAG pipelines, agent orchestration), full-stack platforms, and large-scale test automation across healthcare, fintech, real estate, and supply-chain domains.

🤖 AI/ML Expertise: Trained custom GPT models from scratch with PyTorch on NVIDIA Ada GPUs, integrated Claude API and ChatGPT into production systems, built intelligent agents for decision support.

🔧 Full-Stack Mastery: .NET Core since 2014, React/Angular ecosystems, real-time WebRTC platforms, microservices architecture, and enterprise system integrations.

🧪 Testing Excellence: Comprehensive test automation with Jest, Cypress, Playwright, Selenium. CI/CD pipeline integration and expanding coverage across all testing domains.

10 Copy/Paste AI Prompts for Developers — No Fill-in-the-Blanks

A tight, opinionated collection of prompts I use daily across all my projects. Stack-agnostic, ready to paste into any AI assistant. Covers refactoring, debugging, security audits, AI output quality, and more.

Why it exists: Most prompt repos have you fill in brackets or pick a framework. These just work — paste, describe your problem, get results.
