From Logo
to LLMs.

I've been building software since first grade. Today I combine deep engineering, cloud architecture, AI product building, and UX thinking — end to end.

01

The story starts in first grade.

Years of building

“I've never had a moment where I stopped wanting to build something. That drive hasn't faded — it's compounded.”

AWS · GCP · Azure · OCIUX — John Bryce 2013CTO — HealthcareOracle Cloud Architect

My teacher introduced Logo in first grade — the turtle drawing language. I told a machine what to do, and it did it. That was everything. By second grade I was writing Basic on a Commodore. By ninth grade I was building websites in Notepad and uploading them to Geocities at 3am. Not because anyone asked me to. Because I couldn't stop.

That drive didn't fade — it compounded.

I spent years at NICE, growing from computer technician to software engineer. I built systems, traveled internationally for implementations, and shipped a quote-and-pricing system that replaced a fragile Excel-based process. It served the company for years.

Then came the startup years. Products, mobile apps, SaaS systems. I led engineering teams, wore every hat, shipped things that people actually used.

One of those chapters was serving as CTO of a healthcare company building fetal monitoring systems. We replaced aging hospital technology with a modern system and deployed it into real operating hospitals in Israel. That one felt real.

In 2013 I formalized what I'd always done intuitively — I studied UX at John Bryce College. I've believed ever since that the best systems aren't just correct. They're usable.

At Oracle I became a cloud architect. I ran hands-on workshops that took enterprise customers from zero to production on the cloud. Not slides. Real infrastructure. Real systems.

Since 2024, I've gone deep into AI — LLM-based products, AI workflows, and modern development environments. The space is moving fast. I'm moving with it.

Thirty-plus years in. Still building. Still learning.

02

Four pillars. One engineer.

I don't specialize in one layer — I think and build across all of them.

Software Engineering

I've written production code for over 30 years — in Basic, Pascal, C#, Java, JavaScript, TypeScript, Python, and more. I understand systems from first principles: how they're built, how they fail, and how to make them scale. I'm a real engineer who still writes real code.

  • Full-stack development
  • System design & API architecture
  • Performance optimization
  • Mobile development
  • Backend systems
  • Scalable infrastructure

Cloud Architecture

Real-world delivery across all four major clouds — AWS, GCP, Azure, and OCI. At Oracle I designed and ran hands-on cloud workshops, taking enterprise teams from zero to production. I understand the real constraints: cost, security, scalability, and operational complexity.

  • AWS · GCP · Azure · OCI
  • Cloud architecture & design
  • Infrastructure as Code
  • Cloud migration strategy
  • Workshop delivery
  • Enterprise cloud adoption

AI Systems

Since 2024, fully focused on the AI frontier. I build LLM-based products, AI workflows, and modern AI development environments — systems that work in production, not just in demos. I combine engineering depth with product thinking to ship AI features that matter.

  • LLM integration & fine-tuning
  • AI workflow design
  • RAG systems
  • Prompt engineering
  • AI product building
  • AI dev environments

UX Thinking

Formally trained in UX at John Bryce College (2013), practitioner by conviction. I apply UX thinking not just to interfaces, but to APIs, developer tools, and system interactions. The best systems aren't just correct — they're usable, clear, and thoughtfully designed.

  • User research principles
  • Interface design
  • Developer UX
  • Usability & accessibility
  • Information architecture
  • Design systems

03

The journey.

From first grade to the AI frontier — milestone by milestone.

Early 1990s1st Grade

First Line of Code

My teacher introduced Logo — the turtle drawing language. I told a machine what to do, and it did it. That was everything. The obsession started here.

Mid 1990s2nd Grade

Basic on Commodore

Moved to Basic on Commodore computers. Learning to make programs that did things — input, logic, output. The fundamentals, before I knew they were fundamentals.

Late 1990s9th Grade

HTML on Geocities

Building websites in Notepad, uploading them to Geocities. Learning the web by doing it. Not because anyone asked — because I couldn't stop.

2000sEarly Career

NICE Systems

Rose from computer technician to software engineer. Built systems, integrations, and internal tools. Traveled internationally for implementations and workshops. Shipped a quote/pricing system that replaced a fragile Excel-based process — it served the company for years.

2013Certification

UX Studies — John Bryce College

Formalized what I'd always practiced: systems should be usable, not just functional. UX thinking became part of how I approach every layer of what I build.

2010sStartup Years

CTO — Healthcare Tech

Led engineering across multiple startups. Served as CTO of a company building fetal monitoring systems for hospitals. We replaced aging clinical technology with a modern system — deployed in real operating hospitals in Israel.

2010s – 2020sEnterprise

Oracle — Cloud Architect

Designed and delivered hands-on cloud workshops, guiding enterprise customers from zero to production on Oracle Cloud and beyond. Not slides — real infrastructure, real outcomes.

2024 –Now

AI Systems & Products

Fully focused on the AI frontier. LLM-based products, AI workflows, modern AI development environments, and prompt engineering. Building at the edge of what's possible.

04

Built things that worked.

A few highlights from 30+ years of shipping real software.

01

Hospital-Grade Medical Systems

Built and deployed fetal monitoring systems into real operating hospitals in Israel, serving clinical staff and supporting live patient care.

02

Enterprise Pricing System

At NICE, built a quote/pricing system that replaced a fragile Excel-based process. It served the company reliably for years.

03

Global Cloud Enablement

At Oracle, delivered hands-on cloud workshops across regions — guiding enterprise teams from zero to production on live cloud infrastructure.

04

Multi-Cloud Practitioner

Real-world delivery experience across all four major clouds: AWS, GCP, Azure, and OCI. Running systems, not certification slides.

05

End-to-End Product Building

From backend architecture to mobile apps to AI workflows. Web, mobile, cloud, AI — built and shipped across every layer of the stack.

06

Engineering + UX Combined

One of few engineers who are also formally trained in UX — delivering systems that are not only correct, but genuinely usable.

05

Why this combination is rare.

Most specialists go deep in one area. I've spent 30+ years going deep in four.

Most architects don't code. I do.

I've written production code since first grade and haven't stopped. I bring architectural thinking without losing the hands-on depth that makes it real. I read code, write code, review code — that doesn't change based on title.

Most engineers don't think in UX. I do.

Formally trained in UX and practicing it across everything I touch — from interfaces to APIs to developer tooling. Usability isn't an afterthought in my work. It's part of the design.

Most builders aren't fluent in AI yet. I am.

Since 2024 I've been working at the AI frontier — not just using AI tools, but building AI products, workflows, and systems that function in production. The gap between AI demos and AI products is where I live.

“I can join a technical design session, open a pull request, review a UI, and advise on AI strategy — in the same week.

If you're building something real and need someone who can see the whole board — I might be who you're looking for.

06 — Let's talk

Let's build something.

I'm available for the right engagements. If you're building something real and need someone who can see the whole picture — from architecture to AI to UX — I'd love to talk.
