@matthewwilliams3
Senior web engineer specializing in scalable Rails and Python microservices, CI/CD, and observability.
United StatesWhat I'm looking for
I am an accomplished senior web developer and infrastructure-minded engineer with 10+ years building scalable web platforms using Ruby on Rails, Python microservices, and modern frontend frameworks. I focus on designing resilient architectures, containerization, and CI/CD automation to improve reliability and accelerate delivery.
I've led migrations to microservices and container orchestration on AWS, reduced latency and deployment times significantly, and implemented observability and testing practices that cut incident rates and improved performance. I also mentor engineers and establish standards for API design, 12-factor apps, and code review.
My work has produced measurable business impact—reducing hosting costs, increasing throughput, and enabling enterprise contracts—while fostering cross-functional collaboration and developer productivity improvements.
