Dennis Blommesteijn is a pragmatic technical lead and system architect with 13+ years of professional experience and over a decade specialising in Ruby on Rails. He combines hands-on backend development (Ruby, Python, Node.js) and full-stack work (React, Angular) with engineering management, delivering elegant MVPs that balance long-term design and business needs. At companies from startups to enterprise (CareerBuilder, SURF) and as a freelancer, he’s led architecture, infrastructure and team enablement while championing SCRUM done right, TDD, CI/CD and extreme programming. He’s particularly focused on uncovering edge cases and relentlessly chasing the required business information to turn vague requirements into workable specifications. Comfortable with systems integration, NLP research, high-throughput storage and cloud DevOps, he blends academic rigor (MSc Software Engineering) with practical delivery. Based in Utrecht, he’s the kind of lead who flags risks early, empowers teams, and prefers iterative architecture over large up-front plans.
