At SODIS Lab, I refactored a legacy Angular.js and jQuery application into a SvelteKit and React micro-frontend architecture. I also delivered a collaborative project-documentation system with real-time editing, replacing a slow, error-prone manual process.

At System Solutions, I delivered a social simulation prototype spanning Svelte, Node.js, and MongoDB. Earlier, at VPluse, I built a custom CRM with Node.js and React and led a four-person IT department.
