Built an AI-powered website builder that generates structured website code from natural-language prompts. Developed the React frontend and Node.js/Express REST APIs, integrated DeepSeek via OpenRouter for AI generation, and used MongoDB for storing generated website data. Implemented JWT/Firebase authentication and a Stripe-based credit system for a scalable SaaS workflow.
Project Overview
Designed and developed two modern, visually driven websites for different industries: a premium interior design brand and a futuristic drone technology platform.
The interior design website focuses on luxury, elegance, and visual storytelling, using large imagery, refined typography, service sections, project showcases, and clear consultation/quote calls to action.
The drone technology website takes a more technical and futuristic approach, featuring a dark interface, vibrant accents, industry use cases, drone product showcases, specifications, image galleries, and quote-request interactions.
Together, these projects demonstrate my ability to adapt UI/UX, visual design, and frontend development to completely different industries while maintaining responsive layouts, strong visual hierarchy, engaging interactions, and polished user experiences.
My Role
I handled the design and development of both websites, including the overall UI/UX direction, responsive layouts, visual sections, navigation, content presentation, interactive elements, and conversion-focused calls to action.
Healthcare software has a different failure mode: a bug isn't a bad user experience, it's a compliance event.
I built the admin panel for an FDA-cleared medical device administration platform — patient management, device administration, compliance tracking, and reporting — running at 50,000+ concurrent users in production.
The engineering challenge was less about features than about correctness under load: keeping data consistent and auditable while the system scaled.
