End-to-end ownership. Scalable results.
I build systems that grow with your business, focusing on measurable outcomes and technical excellence.
I'm Ivan Ruiz, a Senior Full-Stack Engineer based in Mississauga, Ontario. My career has been defined by a passion for solving complex architectural puzzles and delivering high-performance applications that serve thousands of users.
Throughout my journey, I've developed a preference for measurable outcomes. Whether it's reducing server costs through efficient cloud-native patterns or improving user satisfaction by 25% through a platform redesign, I believe engineering should always be tied to impact.
Currently, I am deeply focused on multi-tenant SaaS architectures and the integration of AI modules to drive operational efficiency. I enjoy the challenge of building isolated, secure, and cost-aware systems that can scale from an initial prototype to a robust enterprise solution.
Impact Driven
Every line of code should move the needle. I focus on performance, reliability, and time-to-market.
Architecture First
Building the right foundation ensures scalability. I specialize in microservices and multi-tenant isolation.
Team Leadership
Experience leading and mentoring teams, establishing QA processes, and fostering a culture of excellence.
Lifelong Learner
From homelab experiments to continuous learning and cloud-native engineering, I stay at the forefront of modern engineering.

Values I code by:
- Simplicity over complexity until complexity is necessary.
- Security and performance are not features, they are requirements.
- Documentation is as important as the implementation.
- Automate the repetitive to focus on the creative.
