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.

*NO AGENCIES, Single Engineers Only* SeatWaves is a live ticket resale platform with a fully operational web version, complete Broker API, and TicketMaster API integration already in production. We are looking for a skilled mobile developer to finish the final leg of our iOS and Android app — not start from scratch. The previous development team completed approximately 88% of the mobile frontend UI. The Figma designs are finalized. The backend APIs are live. What we need now is someone to come in, understand the existing codebase quickly, wire everything together, and deliver a production-ready app. What's Already Done → Live web platform (full-featured, production-ready) → Broker API — fully built and operational → TicketMaster API — fully integrated → Figma UI/UX designs for iOS and Android — finalized and approved → iOS & Android frontend — ~88% complete (UI built, needs backend wiring) What Needs to Be Completed → Wire existing mobile frontend to live backend APIs (authentication, listings, checkout flows, broker inventory) → Integrate TicketNetwork API — inventory feed and seat availability → Implement interactive seat map API integration → Bot protection and rate limiting hardened for high-traffic onsale events → Queue integrity and load-resilience architecture for peak traffic → End-to-end QA testing on iOS and Android → Store-ready builds (App Store + Google Play submission prep) Why $1,500? We want to be transparent about the budget and why we feel it's fair for the right developer. The heavy lifting has already been done. The UI is built. The APIs exist. The designs are approved. This engagement is scoped specifically around integration, security hardening, and QA — not ground-up development. We estimate 3–5 weeks of focused work for an experienced React Native or Flutter developer who can hit the ground running. We are not paying for a full build — we are paying for a sharp finisher who can take 88% to 100% efficiently and cleanly. We're offering $1,500 fixed price for a clearly scoped, well-documented completion sprint. Applicants who try to reprice this into a full rebuild will not be considered. Who We're Looking For → Strong experience with React Native or Flutter (please specify) → Proven ability to inherit and work within existing codebases → Experience integrating third-party APIs (ticketing, payments, or marketplace preferred) → Familiarity with security best practices for high-traffic consumer apps → Clear communicator — we need daily async updates and weekly check-ins → Portfolio or GitHub showing mobile apps you've shipped, not just started To be considered, please include the following in your proposal: 1. A brief overview of a similar project you've completed (inherited codebase or API integration work preferred) 2. Your estimated timeline to complete the remaining scope 3. Your preferred framework (React Native or Flutter) and why 4. Any questions you have about the existing stack Generic proposals will be declined. We're looking for someone who has read this carefully and can speak specifically to the work at hand. READY TO FINISH SOMETHING REAL? The foundation is built. The designs are done. The APIs are live. We need a finisher — someone who delivers, not someone who starts over.

This is a Flutterflow app called CARS which stands for Cybersecurity Awareness & Resilience Solution. I am a Phd student at NSU and I will be engaging in developmental research for microbusiness owners testing cyber awareness and resilience for their microbusinesses. This is intentionally a minimal research app. There is no backend all logic is handled in FlutterFlow + Firestore. The app enforces sequential viewing of videos and tracks completion and rewatch behavior only. The focus is on simplicity, reliability, and clean UX. Avoid over-engineering. There are 102 videos that have already been loaded via csv via Rowy into Firebase/Firestore. You already have: videoId title module order videoUrl and the videos are set-up to play sequentially one after another. If you get the job, I will provide the csv with placeholders for videourl for privacy. Please review the attached Developer Brief to get an idea of the specifics of this job. Thank you.
