Ron S.

I am a US-based Computer Scientist, Technical Architect, and AI Solutions Engineer with 30 years of experience. I am certified as Expert Vetted on UpWork (top <1% of all users), with 5-star rating, rave reviews, and 100% success score. ➤ Career Highlights I've worked with startups, Fortune 500 companies (Ford), and government agencies (CDC), and have held executive roles (CTO, CEO) at two successful startups doing millions in revenue with products reaching tens of millions of users worldwide. I also author and maintain open source libraries downloaded 25+ million times per month, used in production at GitHub and Microsoft. GitHub uses them in their core infrastructure and is one of my financial sponsors (more info below). ➤ What I Do I design and build software systems that scale — from architecture blueprints and database infrastructure to full production applications (backend, infrascruture, frontend, and more). My recent focus has been on AI-powered platforms, including LLM integration, AI agent development, multi-agent orchestration, and tool-calling pipelines using OpenAI, Claude, and open source models. ➤ AI & Agentic Development I build production AI systems — not wrappers around ChatGPT. Recent work includes multi-agent orchestration with tool-calling loops, MCP server development for document analysis, LLM-powered scoring and recommendation engines, and AI-assisted codebase analysis across 170k+ line codebases. I work daily inside Claude Code, OpenAI, and OpenRouter APIs. ➤ Why Technical Architecture Matters Most technical projects fail because they have a poor architecture blueprint — or none at all. Most developers aren't architects, and without the right foundation, even projects that make it to launch grind to a halt within months as technical debt makes it impossible to build further. I create full "bone structures" on the code, database, and server levels that establish patterns developers can build on confidently. By mapping out growth tracks early, we ensure the system can scale without endless rewrites. This is the difference between another great idea that stalls and a multi-million user success story. ➤ Open Source I wrote and maintain multiple open source libraries used worldwide, collectively downloaded over 25 million times per month. Highlights include the TypeScript compiler tools (~3M/month), node-html-parser (~20M/month), and node-html-markdown (~1.4M/month). GitHub itself financially sponsors this work, which is part of their core infrastructure. ➤ Working with Me I partner with startups, established companies, and enterprise teams who need expert-level architecture, AI integration, or full-stack development. I often deliver 2-4x faster than typical senior developers — clients regularly find the final cost beats offshore alternatives, because it's done right the first time and delivered faster. ➤ UpWork Stats ⁍ Expert Vetted (top <1%) + Top Rated Plus ⁍ $400k+ completed, 5-star rating ⁍ Rave reviews (most clients leave multiple reviews per project) ⁍ Almost all clients form long-term partnerships ➤ More Info ⁍ UpWork Reviews: See below ⁍ GitHub: nonara (pinned projects are all maintained by me) ➤ Keywords TypeScript, JavaScript, Node.js, Python, React, PostgreSQL, MySQL, AWS, Docker, Kubernetes, Electron, C#, .NET, Swift, Prisma, Redis, GraphQL, REST API, Next.js, FastAPI, Flask, Terraform, Pulumi, Shopify, AI Agent Development, LLM Integration, OpenAI API, Claude API, MCP Server, Model Context Protocol, Multi-Agent Systems, Tool-Calling Pipeline, RAG, Prompt Engineering, Context Engineering, Claude Code SDK, SWE-Agent, AI Agent SDK, Multi-Agent Orchestration, Web Scraping, Playwright, Browser Automation, Browser Extension Development, Chrome Extension, Cross-browser Extension, Solutions Architecture, Database Optimization, Infrastructure as Code, DevOps, CI/CD, Full-Stack Development, Technical Leadership, Code Rescue, ANTLR, CEF, Chromium Embedded Framework, ts-patch, TypeScript Compiler Plugin, TypeScript AST, TypeScript Compiler, Compiler Design, Language Server Protocol, LSP, Parser Development, BrowserView, Embedded Browser, Desktop Application, node-html-parser, node-html-markdown, V8 Engine, PostgreSQL V8, Custom Protocol, Reverse Engineering, Packet Analysis, WireShark Plugin, ArtNet, DMX, pcap, Database Forensic Recovery, IPv6 Scraping, Shopify App, Remix, Angular, PHP, Bash, OAuth, Auth0, SSO, JWT, WebRTC, SocketIO, Monorepo, Webpack, Vite, WordPress, n8n, Node-RED, Twilio, Stripe, GitHub Actions, GitLab CI, React Native, Firebase, pgvector, Embeddings, Vector Database, SaaS Architecture, Multi-tenant
