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.

I'm a solo, non-techncial founder and need someone to help me build and launch a mobile app. I had a previous team build a semi-functional prototype in TestFlight and have identified a number of areas in which certain features aren't working as envisioned. The project involves leveraging the work done to-date on the existing app to ensure it is user-friendly and aligns with the project vision. The ideal candidate should have experience in mobile app development and be able to work iteratively to improve the app's functionality and design. As we move forward, I can provide GitHub access to the underlying code the team has delivered to-date as well as inviting you to as a test user in TestFlight and sharing the notes I've compiled on desired improvements / changes. I'm open to a fee arrangement or, with the right person/group, a longer-term / creative partnership.

Expectations include setting up development, staging and production environments in AWS, creating and managing the CI/CD pipeline and support for front end development and integration with the API.

I came across your profile and wanted to reach out regarding a mobile application project we are currently developing. We are seeking a U.S.-based Flutter developer with strong front-end and UI/UX implementation skills for a consumer-focused mobile app currently in storyboard and architecture phase. The project includes animated user interactions, backend-driven data integration, dynamic forms/screens, and a modern mobile user experience. At this stage, we are intentionally keeping specific app functions and business concepts confidential until we determine mutual fit. A signed NDA will be required prior to sharing detailed specifications, workflows, datasets, and design assets. The ideal candidate should have experience with: • Flutter mobile application development • Lottie or similar animation integration • API and backend data connectivity • Dynamic UI rendering and state management • Responsive mobile UI/UX implementation • Performance optimization for animation-heavy interfaces • Clean and scalable code structure • Git/version control workflows • Collaborative development and milestone-based delivery We are looking for someone who can think beyond static screens and help implement a polished, engaging mobile experience. Project structure will likely include milestone billing tied to defined deliverables such as: • Initial UI framework/setup • Core screen implementation • Backend/API integration • Animation integration • Testing/refinement phases If this sounds aligned with your background, I’d appreciate seeing examples of Flutter apps you’ve worked on that involved both interactive UI elements and backend-driven functionality. Thank you, Casey
