Hi, my name is

John Pratt.

I build things for the cloud.

I'm a software engineer all about creating top-tier cloud solutions. Right now, I'm grinding through short-term engagements at Pratt Solutions, working for myself while I hunt down my next full-time/long-term role. No hesitation - just getting after it.

About Me

I'm John, and I build software that makes a difference. My journey with programming kicked off when I took a computer science class in high school. I didn't just show up - I dominated, landing in the top 5% of students both years. That lit a fire in me, and I've been pushing the limits in software engineering ever since

Fast-forward to today, and I've had the privilege of working for an aerospace company, two startups, two banks, an energy company, and myself. These days, I'm all about building rock-solid, scalable, and secure solutions as a freelance software developer and consultant, while I hunt down my next long-term W2/contract role. No excuses, just results.

Here are a few technologies I've been working with recently:

Amazon Web Services (AWS)
Microsoft Azure
Terraform (OSS, Enterprise)
Python (2/3)
Google Cloud (GCP)
Bash
PowerShell
JavaScript (Node.js, React)
Java (Spring Boot)
CI/CD pipelines
Docker
gatsby
Snowflake
SQL
Kubernetes
HashiCorp Products
Git
GitHub
Bitbucket
Selenium
Large Language Models (ChatGPT, OpenAI API, Claude, Gemini, DeepSeek)
