Cleaning Elevation Podcast - Lovable

Users can simply enter a description, and the app uses advanced AI models to create unique images for everything from concept art to social media visuals.
I handled the full frontend build using React, TypeScript, Next.js, and TailwindCSS, focusing on a clean UI, responsive design, and smooth user interactions.

Dream AI

I built a lightweight, responsive single-page shop assistant app using pure HTML, CSS, and JavaScript.
I focused on clean UI/UX, fast load times, and seamless interactivity using vanilla JS for DOM manipulation and local state handling. While the project uses no frameworks, I also have strong experience with React and SCSS, and often apply those in production-grade apps.

Shop Assitant

I handled the fullstack development, including multi-model integration, chatbot creation tools, user authentication, and a frontend dashboard for managing bot settings. End users can chat directly with the bots through a sleek UI that supports real-time messaging and contextual memory.

Supennind Bot

I built the fullstack solution from scratch — from the conversation logic and AI integration, to the UI/UX and backend. The chatbot was trained with mental health-focused prompts and resources, ensuring safe and empathetic interactions. I also implemented user session handling, message history, and content filtering to ensure privacy and reliability.
