Background

About Marcin Malec

I'm a full stack web developer with over 5 years of professional experience, currently working as a Lead Developer specializing in Ruby on Rails applications. My work spans front-end templating (HTML, SCSS, CoffeeScript) to back-end infrastructure (PostgreSQL, AWS S3, AWS Lambda), with a strong focus on reliability, maintainability, and delivering real value to users. I've led small teams, collaborated closely with project managers, and contributed to hiring decisions. I also regularly assist our customer support team, resolving smaller issues directly and creating scoped tasks for larger ones, to keep user experience front and center in development priorities. Highlights of my work include- Creating a media moderation and tagging system using AWS Rekognition - Designed a simple traffic management process for coordinating merges and deployments, ensuring only verified changes reached production and minimizing live site risks - Reducing AWS S3 storage costs by through smarter object lifecycle management - Resolving live site issues and documenting operational procedures to support long-term stability Before entering the industry, I earned a BSc in Computer Science and a BComm in Entrepreneurship from the University of Calgary. I enjoy working across the stack, solving problems, and building tools that make software better for users and developers alike. Always happy to connect, especially if you want to chat about tech, games, or painting minis
