Building Tech Excellence through AI Engineering, Quality Assurance, Strategic Technical Project Management and an Entrepreneurial Mindset

I’m Yosuan Crespo, a Computer Science Engineer with 17+ years of real‑world experience dedicated to building and ensuring the quality of impactful software solutions and helping teams adopt modern technologies. A relentless curiosity and a commitment to excellence have driven my journey in the tech world.

My career began with a fascination for how software could solve real-world problems. This quickly evolved into a dual focus: not only crafting elegant and efficient code, but also ensuring that the resulting software is robust, reliable and delivers an exceptional user experience. This unique blend of development prowess and a quality-first mindset has been the cornerstone of my approach, allowing me to lead teams and projects that consistently exceed expectations.

My Professional Journey & Philosophy

Throughout my career, I’ve had the privilege of working with dynamic companies like Midnight Network, RVshare, BairesDev, Blubird, Telus, NYU Langone Hospital and ThoughtWorks, where I’ve contributed to and led the development and quality assurance of a wide array of software projects. From architecting scalable Web3, Cloud and AI-powered systems to championing Shift-Left testing, Agile methodologies (TDD, BDD, SDD) and AI-driven DevOps cultures, my focus has always been on fostering innovation, collaboration and continuous improvement. As a professional, I, Yosuan Crespo, always prioritize these values.

As a Senior QA Lead, AI & Automation Engineer, I leverage AI Engineering principles to thrive on mentoring talented developers, defining technical roadmaps and translating business visions into tangible, high-quality software products. My experience in Software Quality has equipped me with a critical eye for detail and a strategic approach to testing, ensuring that every solution I’m involved with meets the highest standards of performance, security and usability. I’m proficient in designing and implementing comprehensive test strategies and leveraging tools that enhance efficiency and coverage.
