I am building a ride-sharing mobile application that groups people traveling in the same direction so they can share a ride and split the cost automatically.

This is similar to Uber Pool, but focused on smaller, local commuter groups (work, school, daily travel). 🎯 What I Need I am looking for a mobile app developer or technical cofounder who can help build the first version of this application. The MVP should allow: User registration and login Setting pickup and destination Matching users going in the same direction Creating shared rides (2–4 passengers) Splitting ride cost automatically Basic map integration (Google Maps or similar) Simple payment system (Stripe or simulated payments) Basic admin panel (optional but preferred) 🛠 Required Skills Flutter or React Native (preferred) Firebase or backend experience API integration (maps, payments) Experience building MVPs or startups Knowledge of ride-sharing or location-based apps is a plus 📊 How We Will Work Start with a simple MVP (not a full Uber-level system) Build step-by-step and test quickly Focus on real users in one city first Agile communication (weekly updates or faster if needed) Open to suggestions to improve the product 🤝 What I Am Looking For Someone serious and reliable Someone who can work independently Someone interested in a long-term project or startup opportunity Paid work initially, with potential for partnership if things go well 🚀 Project Goal The goal is to launch a working MVP within a few weeks/months and test real demand in a local market before scaling. 📩 If Interested Please message me with: Your experience Similar apps you have built Estimated cost and timeline Your preferred tech stack

COREX MVP Native-feeling iOS and Android app (using a cross-platform framework like Flutter or React Native) User login and profiles COREX onboarding assessment (goals, experience, injuries) AI-generated 15-minute rotational workouts Exercise library with videos and instructions Workout timer and progress tracking Basic AI chat coach for workout and recovery questions Subscription/payment integration Admin portal to add or update workouts and content Save for Version 2 These are valuable, but they can wait: Camera-based form analysis Wearable integrations Advanced nutrition planning Community features Leaderboards and challenges Franchise/business dashboards Live trainer messaging Upwork budget suggestion UX/UI design App development AI integration Testing App Store and Google Play launch That gives you control over quality and payments. One thing I’d add Rather than describing it as just another fitness app, position COREX as a specialized AI rotational training platform. That’s what makes it stand out. For example: “COREX is an AI-powered rotational fitness platform that delivers personalized 15-minute workouts designed to improve core strength, mobility, stability, athletic performance, and functional movement through our proprietary rotational training methodology.” That description is much more distinctive than “fitness app.” My recommendation If I were helping you build this, I’d focus on creating something impressive enough to demonstrate to investors, gym owners, and potential partners—not every feature you eventually want. A polished MVP that users enjoy is often more valuable than a feature-heavy app that’s unfinished. I also think your app could have a clear advantage if it emphasizes the science of rotational training rather than trying to compete with broad fitness apps. That gives COREX a unique identity from day one. The product and program itself is trademarked and patent pending

I’m building Elevyn, a platform designed to help people better understand themselves through connected data, intentional reflection, and AI-generated insights. This is not a social media platform. This is not a productivity app. This is not just another trading journal. Elevyn is an operating system for self-mastery, with trading serving as the first environment where personal growth becomes measurable. Most apps collect data. Elevyn is designed to observe. The goal is to connect information across different areas of a person’s life and uncover meaningful patterns that help them improve their decision-making, habits, discipline, and overall performance. The Vision Users will log information such as: • Sleep • Mood • Daily reflections • Workouts • Morning routines • Trading activity • Goals • Habits • Personal notes Instead of simply displaying this data, Elevyn will analyze relationships between it and surface meaningful insights. Examples include: • “You slept less than 5 hours before 7 of your last 10 losing trades.” • “Your win rate increases after completing your morning routine.” • “You tend to become more impulsive after multiple winning days.” • “Your consistency improves when workouts and journaling happen on the same day.” The long-term vision is an intelligent system that continuously helps users become more self-aware. Current Stage I already have: • Brand identity • Vision and philosophy • User flows • Interactive prototype • Core feature planning • Long-term roadmap I’m now looking for a developer or small team (2-3 people) to build the first production version. What I’m Looking For I’m looking for someone who can think beyond simply building screens. I want someone who can: • Build scalable architecture • Recommend the best technologies • Think through user experience • Ask thoughtful questions • Help solve technical challenges • Build for future AI integrations • Create clean, maintainable code Experience with AI, analytics, mobile applications, and scalable backend systems is a significant advantage. Technology (Open to Recommendations) I’m open to your recommendations, but I’m considering: • Flutter or React Native • Node.js or Python backend • PostgreSQL • Firebase/Supabase • AWS • AI integrations (OpenAI or similar) • Secure authentication and cloud infrastructure Long-Term Vision Trading is only the beginning. The underlying engine should eventually support entrepreneurs, athletes, creators, students, and anyone pursuing mastery in a specific area of life. The core idea remains the same: Help people understand themselves by connecting patterns across their behaviors, decisions, and outcomes. Who I’m Looking For I’m looking for someone who believes in building meaningful products—not just completing tasks. If you’re excited about creating a platform that combines psychology, data, AI, and personal development into something people genuinely use to improve their lives, I’d love to hear from you. Please include examples of similar work, your recommended tech stack, and how you would approach building a scalable MVP that can grow over time.

4 WATCHES MOBILE APP CONCEPT AND FUNCTIONS: I created a 14 year calendar that begins on September 23, 2017 and ends on September 23, 2031. The calendar is linked to a clock that's equally divided into four equal sections. Each of the 4 sections represents 1,260 days. The movement of the clock is clockwise, and it begins at the 6PM position. Each of the four sections is divided into 12 sub-sections called "houses." Each of the 12 houses represents 105 days. I have a very rough draft of the app cover page. There will be 8 or 9 tabs total. A "blinking" red block advances clockwise every 105 days to highlight the current position of the 48 houses. MOBILE APP TABS: TAB #1/HOME CURRENT 4 WATCHES "CLOCK" POSITION. Also Shows Current Date, Current "Watch", Current "House" & Current Time of Day. TAB #2 ABOUT THE FOUR WATCHES OF THE NIGHT TAB #3 DAILY CALENDAR: This is an actual functioning calendar app. Users are encouraged to post significant news events that occurred each day; TAB #4 14 YEAR CALENDAR. This tab breaks out to a list of 14 sub-tabs for the years 2017 thru 2031. These 14 sub-tabs break out to 12 more sub-tabs for each month of the corresponding year. This calendar can be edited by the user. TAB # 5 LIST OF THE 48 HOUSE NUMBERS AND THEIR DATES. This tab simply shows a list of the 48 Houses and their dates. For example: #1 September 23, 2017 - January 5, 2018 #2 January 6, 2018 - April 20, 2018 TAB #6 TO BE DETERMINED... TAB #7 Jump To House [1 to 48] This page allows users to enter numbers 1 through 48 to view the 105 day span of each "house" set against the calendar year. TAB #8 Jump To Any of the 5040 days [1 to 5040]. This page allows users to enter a number from 1 to 5040, to jump to that particular calendar day within the 14 year calendar. TAB #9 MERCH/SHOPPING

We are looking to do a new build of our patch bay label designer tool. Customers are currently able to pick their model of patch bay, add text labels, colorize, and group. They can then checkout and it creates print ready artwork for our team to produce. The UI is a bit clunky and there are some features we want to add such as an admin tool to add and edit labels.
