    In my professional career, I've worked on many projects for very profitable companies (ActiveCampaign, HomeLight) to help make their products scale, keep customers happy, and speed up their rate of code deployment. For ActiveCampaign, an email marketing & automation company, I helped speed up their CI/CD pipelines to delivery their frontend app (built in Ember) twice as fast, and I improved their email-to-inbox rate (this service was built in PHP) by 25%. I was also responsible for the creation of their custom fields product, and crafted a custom, scaleable solution for their customers. My passion is to set up efficient quality gates that automatically perform tests and deploy code when it is pushed to source control (Git, GitLab, etc.). Keeping quality code flowing and delivered continuously helps companies maintain a fast pace in today's competitive market. When I haven't worked for a larger company, I've built custom websites for photographers, artists, or bloggers. I know when to send customers to a custom solution or when it would be in their better interest to use products available today that would be simpler and more financially feasible for them (SquareSpace, WordPress, etc).

    30+ years with research groups and startups handling a very wide variety of projects. Working in smaller projects has pushed me to be very flexible and to pick up new skills easily. Since 2006, I have been programming full time for a small company that takes online donations for non-profits. This involves everything from the back-end, server side code for handling transactions, database maintenance, client and donor reporting and management, to the actual design and maintenance of our client's transaction web pages. We try to preserve the look and feel of our client home sites so I have seen about every combination of web page design out there.

    I have ten years experience in geospatial data analysis and reporting, and three years in web applications development. In every office I worked, the data processing tools I developed significantly cut time spent on gathering and preparing data, while simultaneously improving the communication of that data among networked systems. Later on, I started focusing more on the web applications side of software development, especially with open-source technologies. Now I share my skills with the rest of the world as a freelance web developer. I am particularly skilled with presenting geospatial data on various maps like Google and Leaflet. I am also quite adept with regular expressions (pattern matching) for finding and extracting information from a wide variety of source formats. My curiosity and problem-solving skills make me great at coming up with cleverly simple answers to complex problems. Bring me your challenges; I'll provide you solutions!

I'm a senior full-stack developer and systems architect with 15+ years of experience leading projects from idea to deployment. I’ve helped startups launch, enterprises scale, and legacy platforms evolve, with code that lasts and UX that feels good to use. 💡 Past Projects Include: - A $500M real-time fintech trading system (web + mobile) - A $100M real estate CRM platform from scratch - AI-integrated cybersecurity systems for live threat response - High-performance cross-platform mobile apps using Flutter, React Native, Swift, Kotlin 🛠 What I Bring: - Architecture & full-stack development (Ruby, Node.js, Python, Rails, React, Vue, Swift, etc.) - Mobile-first and cloud-native builds (AWS, GCP, Heroku, Docker/K8s) - API design, DevOps pipelines, performance tuning, and scaling - Excellent communication, weekly deliverables, zero micromanagement needed ✅ Clients hire me when: - They need to launch something ambitious - Their legacy codebase is a mess and they need a lifeline - They want someone who thinks like an engineer, a strategist, and a founder If you're looking for top-tier technical leadership, hands-on build support, and someone you can trust to handle the whole stack, let’s talk. → Message me and tell me what you're building. I’ll tell you how I’d make it better.
