Hi, I'm David.

Hello! I'm David Crimi, a passionate software developer with a strong foundation in computer science and expertise in backend development, full-stack applications, and cloud technologies. I recently completed my B.Sc. in Computer Science with Honors from York University and am currently working as a Software Analyst Intern at Hitachi Rail.

My technical expertise spans multiple programming languages including Python, Java, C++, and JavaScript. I'm proficient with modern frameworks such as React, Django, Flask, and Next.js, and have experience working with various databases including PostgreSQL, MySQL, MongoDB, and Neo4j. I'm particularly interested in building scalable systems and implementing efficient DevOps practices.

I've developed several impactful projects, including Impactify—an IoT-based brain health monitoring system for contact sports that won first place at Hack the Valley among 400 participants. I also created a Six Degrees of Kevin Bacon application using Neo4j, demonstrating advanced graph traversal algorithms, and an Optimal Uber Finder application that uses geospatial algorithms to save users an average of 30% on ride costs.

As an AWS Certified Developer Associate and Meta Backend Developer certificate holder, I'm committed to industry best practices and continuous learning. At Hitachi Rail, I've improved CI/CD pipelines using Jenkins and Docker, achieving a 40% reduction in build execution time while enhancing system stability and documentation.
