Nutrista App is a two-sided marketplace and AI-powered nutrition platform that merges automated calorie tracking (similar to Yazio or MyFitnessPal) with direct access to licensed dietitians. I designed and built the full ecosystem using React Native, React, shadcn/ui, Supabase, and Stripe Connect. The platform verifies experts, facilitates professional meal plan purchases, and features an AI-driven dietitian assistant. I implemented the end-to-end marketplace logic, including secure professional onboarding, messaging, and payment flows, while developing the database schema and admin dashboards—iterating rapidly in Cursor.

Sum.video is an AI tool that generates instant summaries and audio versions of YouTube videos. I built the platform using React, shadcn/ui, Supabase, and multiple AI APIs (OpenAI, Whisper, etc.). The product extracts captions, summarizes content, generates TTS, and delivers results in a clean, shareable UI. I also implemented Stripe billing and usage-based quotas. The app runs thousands of automated background jobs and handles content caching for speed. I developed the landing page, subscription flow, and back-end processing pipeline.

Dead.Domains is a specialized discovery engine for locating recently expired domains with branding potential. I built the entire platform end-to-end using React, shadcn/ui, Supabase, and Cursor-driven rapid prototyping. It automatically aggregates tens of thousands of domains, ranks them by uniqueness, marketing potential, and availability, and presents them through a high-speed search interface. I implemented background jobs for data refresh, an API for programmatic access, and a clean, minimalist UI optimized for browsing and sharing interesting finds.

Samerocket.club is a matchmaking platform designed to connect founders, engineers, and early-stage startup builders based on skills, interests, and project needs. I designed and developed the product using React, Supabase, and shadcn/ui, with a focus on a high-performance matchmaking algorithm and clean onboarding flows. The platform enables users to create profiles, specify availability, and receive curated matches. I handled database design, authentication, matching logic, and UI/UX, iterating rapidly in Cursor.

Unwait.me helps startup founders track progress by logging what they actually did instead of planning what they should do. I created the full product in React with shadcn/ui, backed by Supabase for real-time syncing and authentication. The app provides fast journaling, weekly summaries, and simple productivity analytics. I built a minimalist UI optimized for daily use and implemented background processing for generating insights. Cursor accelerated rapid iterations on feature design and architecture.

Wishlist.club is a social wishlist app that enables users to create, manage, and share gift lists with friends and family. I built the entire stack with React, Supabase, and shadcn/ui. Core features include shared lists, claim-tracking (to prevent duplicate gifts), and a notification system. I implemented a clean sharing flow, public and private visibility options, and a responsive UI. Cursor was heavily used to scaffold components and automate repetitive tasks.

PiggyBanx is the combination of gamification, social network, education, and the financial market! It changes the way of thinking. The youngsters can create various piggy banks with goals and amounts. Parents can control the youngster's activities and assign them tasks. Piggy gives a friendly interaction when the user slides a coin into the piggy bank, and they can share their activity on their timeline.

PiggyBanx is a simple solution in the parents' hands to educate their children on financial awareness. It creates an interaction between the child and the parent because the parent can give daily tasks to the child, and in return, they earn extra piggy coins for their piggy banks.

We provide banks with a great solution to reach youngsters. We believe in a more financially educated future. Our goal is to provide a great tool that youngsters can enjoy. We also created Piggy as an AI-powered chatbot. Piggy can help banks stay in contact with parents.

iTransmit is a community-powered virus outbreak area identifier that enables users to:
• Check in if they are feeling sick.
• Check the map for infectious areas.
• Get notified when they meet an infected person.

I developed this application for a 24-hour hackathon and later extended it to be a part of my portfolio. As it turned out, I was unable to publish it in the Google Play Store or Apple App Store because I'd need special approval from the national government of the country in question. If you are interested, I'm happy to share a demo.

I volunteered to develop a web front end for the hostel's Dynamic Domain Name System (DDNS) service. Many students in the hostel were future computer science engineers, and many of them had servers to experiment with. With our service, they were able to set an alias for the IP addresses of their servers.
