**About Me 👋** **Senior Full-Stack Engineer | React + TypeScript, Node + AWS | AI/LLM, Real-time Dashboards, Electron + Tauri** I build products that are too complex for a generalist team: web apps with live data, AI and LLM features, HIPAA healthcare software, desktop apps that talk to hardware, and the cloud setup to run it all. 40+ projects shipped across healthcare, fintech, cybersecurity, real estate, logistics, robotics, and agriculture for clients in 10 countries, mostly the US, UK, and Germany. I take a product from idea to production, or join an existing codebase and get it shipping again. **Specialization 1: Full stack web (React, Next.js, Node.js, FastAPI)** SaaS platforms, customer portals, admin dashboards, and REST and GraphQL APIs on PostgreSQL. Most of my time goes into data-heavy interfaces: ECharts and D3 dashboards, force-directed graphs, choropleth maps, candlestick and footprint charts, and live updates over WebSockets. I maintain a 43-component React visualization library and keep charts responsive at 50k+ points by moving work into Web Workers. **Specialization 2: AI and LLM integration** LLM features in production with Claude, OpenAI, and Gemini: LangGraph agents, MCP servers, AI spreadsheet and document import, AI-drafted threat models, and a meeting assistant with live transcription. Plus Playwright scrapers and live market data pipelines into time-series databases. **Specialization 3: Cloud and DevOps (AWS, GCP, Azure)** Serverless backends with Lambda, DynamoDB, AppSync, API Gateway, S3, SQS, and Fargate, infrastructure as code with Terraform and Amplify Gen 2, Cognito auth, Bedrock for AI. CI/CD with GitHub Actions, Docker, Kubernetes, and cloud cost control, so the team ships features instead of babysitting servers. **Specialization 4: Desktop apps (Electron + Tauri)** 15 desktop apps shipped for Windows, macOS, and Linux: offline-first field tools, hardware companions over serial, USB-HID, and BLE, kiosk software, screen recorders, and heavy image, video, and OCR processing. I handle the parts most people avoid: macOS notarization, Windows signing through AWS KMS, and auto-updates from S3. How I work: a short discovery phase first, then a fixed plan. Senior hands on the code, direct communication, overlap with US and EU hours, and honest advice when a simpler solution would serve you better.

I love JavaScript and the JS ecosystem that has sprung up after the creation of NodeJS. I collaborate with independent development teams around the world to write full web applications, and to create UI and other reusable JS components. I also have many years of experience in Java with Spring. I'm always up for discussions that challenges the status quo to find a better way to do things.
In my 18 years developing software, the field of technology and the options available to solve problems has progressed at an amazing pace. Thankfully I have an intense passion for learning new technology and applying it to solve problems. Not only do I enjoy learning the details and ramifications of whats new, but I have the experience to realize when something isn't ready for production, or is the wrong solution to solve the problem. Web application development has come far in the 12+ years that I have been in the field and I have used many different technologies , Java, PHP, Nodejs, Dojo, Angular, Vue etc. and integrated with dozens of 3rd party systems. I have been a developer, a team lead, an architect, and, off the side of my desk, I have done project management, dev management, dev ops and more. In the end, I do whatever needs doing to solve business problems with technology. I love building and solving.
