Hi, I’m John Ruben.

I’m a Technology Leader and Solutions Architect based in Pleasanton, CA, with over 17 years of experience building scalable, high-performance systems across fintech, e-commerce, and enterprise technology.

By day I work as a Principal Software Engineer where I architect cloud-native platforms, financial systems, and e-commerce solutions used by millions. I’ve worked with companies like Western Union, Roostify, and Yapstone, Blackhawk and Credit Acceptance — designing everything from payment gateways to order management systems at massive scale.

I started BITHOG because I believe technology should be accessible to everyone — not just engineers. Whether you’re a developer leveling up your skills, a crypto enthusiast navigating a complex market, or just someone who loves gadgets and wants to stay ahead of the curve, this is your place.

Here at BITHOG you’ll find practical programming tutorials, honest crypto insights, and the latest in tech — written from real-world experience, not just theory.

What I write about:

• 💻 Programming & Software Engineering
• ☁️ Cloud, AWS & Modern Architecture
• ₿ Cryptocurrency & Blockchain
• 🤖 AI, LLMs & Emerging Technologies
• 🔧 Gadgets & Tech Solutions

Let’s geek out together.
