Full-Stack Developer

Full-Stack Developer with 5+ years of hands-on experience creating end-to-end web applications that deliver seamless user experiences.

I’m Mirel, a self-taught full-stack developer with over 5 years of experience.

I began my journey as a frontend developer at Sessions, a startup whose core project was a complex video conferencing tool enhanced with various modules. Over more than three years, I expanded my role and transitioned into a full-stack developer position, contributing across both frontend and backend. From there, I moved on to WebitFactory to build out gaming platforms and Web3 features.

Currently, I'm working at Archbee, a collaborative knowledge base platform, where I own the end-to-end development of core product features, maintain the public @archbee/cli and @archbee/app-widget packages, and build custom rich-text editor blocks with real-time collaboration using Plate and Slate.

I'm passionate about coding and crafting elegant, responsive user interfaces, while also developing backend solutions that are efficient, robust, and built to scale. I thrive in dynamic, fast-paced environments. My adaptability enables me to integrate smoothly into any team, tech stack, or project.

I value clean implementations, strong UI/UX, and a culture where skill is appreciated, expected, and rewarded.
