Hi, I’m Nikos Mastrangelis, a senior full-stack engineer focused on building scalable B2B platforms. With 7+ years in frontend and backend development, I architect robust systems from architecture and authentication to CI/CD, testing, and performance. I’ve led cross-functional squads, mentored developers, and delivered high-quality, user-centric products. I actively leverage AI-driven tools to boost developer productivity and raise overall system quality, while shaping feature roadmaps and driving end-to-end delivery. I thrive in fast-paced, collaborative environments, partner with product owners and designers, and help define roadmaps and feature parity across teams. I’m passionate about accessibility, performance, and delivering delightful experiences for users across web and mobile platforms.…Hi, I’m Nikos Mastrangelis, a senior full-stack engineer focused on building scalable B2B platforms.
