We are seeking an experienced web developer to help build a multi-sided booking platform for real estate service providers (photography, staging, cleaning, inspections, sign installations). The platform will connect realtors (clients) with vendors (service providers), and include an admin portal for managing operations.
The system must support location-based pricing (5-zone model) using Google Maps API (or equivalent), calendar integrations (Google, Outlook, Apple), and secure online payments with commission handling
The ideal candidate should have a strong background in web development, particularly in creating booking systems and user interfaces.

You will build a groundbreaking AI-powered platform focused on empowering crypto traders through data-driven insights and real-time coaching. At its core, we're building an AI engine that aggregates anonymized trading data from thousands of users, categorizing it into "winning" (profitable) and "losing" (unprofitable) pools. This enables the AI to compare an individual's behaviors—such as risk levels, hold times, or asset diversification—against these benchmarks, delivering smart, personalized insights and nudges during live trading. For example, the system might alert: "Your 12x leverage on weekends matches losing traders (only 2.8% profitable)—winners average 24-minute holds; consider scalping." By pooling community data, we help users realign their strategies toward proven winning patterns, starting with crypto to iterate quickly.The platform will be broker-agnostic, requiring secure, read-only API integrations with 10-20 major crypto exchanges (e.g., Binance, Coinbase, Kraken, Gemini, Bitfinex, etc.) for data gathering without executing trades. We'll also include a community stats page for aggregated insights (e.g., comparing winners' vs. losers' average hold times or number of instruments traded) and a premium membership system offering exclusive access to anonymized open positions from winning traders, deeper simulations, and advanced nudges.This MVP will include a responsive website and cross-platform mobile apps (iOS/Android), with scalability for future asset classes. We're seeking experienced fintech developers or a small team to bring this vision to life, drawing from successful Upwork projects in AI trading tools and crypto apps.Scope of WorkAI Engine Development: Build the core AI system using ML/deep learning (e.g., clustering for winner/loser pools, predictive models for risk assessments). Integrate data aggregation from user-connected accounts to generate real-time insights/nudges by comparing individual behaviors to community benchmarks.
Frontend Development: Design intuitive UI/UX for website (responsive) and mobile apps, including dashboards for personal insights, live nudges, and user profiles.
Backend Development: Create a secure server for user auth, data processing, and AI pipelines. Handle anonymized data storage and real-time monitoring.
API Integrations: Implement read-only connections to 10-20 major crypto exchanges (list to be provided; start with top 5 like Binance). Ensure seamless data pulls for trades, positions, leverage, etc.
Community Stats Page: Develop an interactive information hub displaying aggregated stats (e.g., "Winners hold trades 15% longer than losers" or "Losers trade 40+ instruments vs. winners' 2-3 focus"), with visualizations like charts and filters.
Premium Membership Setup: Integrate subscription tiers (e.g., via Stripe) where premium users access exclusive features like anonymized views of winning traders' current open positions, custom AI simulations, and priority nudges.
Other Features: User onboarding with API setup, push notifications (e.g., Firebase), analytics visualizations, and admin tools.
Security & Compliance: Encrypt data, ensure GDPR/CCPA compliance, and add user controls for data sharing.
Testing & Deployment: Comprehensive testing (security, performance) and cloud deployment (e.g., AWS).

Required Skills & ExperienceFintech/crypto platform development (portfolio with trading/AI examples required).
Frontend: React.js/Vue.js (web); React Native/Flutter (apps).

Looking for an expert prompt engineer that understands gpt 4o mini well. We are a healthcare startup looking to extract various data points from medical records utilizing gpt 4o mini. We need someone that understands well how exactly gpt 4o mini works, thinks, and responds so it can be maximized to its fullest. This task requires an NDA and HIPAA agreement prior to starting. Additionally, a few candidates will be interviewed in 2 phases, phase 1 is a sample task to see your results, and phase 2 is a video meeting. We have set up a specific platform for annotated records where you can adjust prompts and play around with it so you can track your progress in real time.
The rate of pay will be broken down in milestones:
1. View our current .py file with all prompts and rewrite all of the prompts
2. Demonstrating perfection across 20 records with previous issues with the new prompts
3. Demonstrating perfection across 100 records with previous issues with the new prompts

Project Overview:

I'm looking for a mobile app developer to help me build an offline, AI-powered journaling app — focused on privacy, emotional clarity, and local-first intelligence.

This project is not just about building an MVP — it's also a learning experience for me. I want to collaborate closely, understand how things are built, and grow alongside the product. You should be someone who’s not only a strong builder, but also a clear communicator who enjoys sharing the “why” behind the work.

🧠 What the App Will Do (MVP Scope):
Let users write or record daily journal entries
Provide AI-generated reflections on emotion, themes, and mood
Allow users to search past entries using natural language
Offer a timeline of journal history with mood and tag filtering
All processing must happen fully offline — no server calls, no external APIs

📱 Platform:
This will be a mobile-first app, starting with Android
All data and AI should run on-device, with privacy and performance in mind

🚀 What You’ll Do:
Collaborate with me to design and build the full app experience
Propose your own tech stack and architecture for an efficient offline build
Help me understand the reasoning behind key decisions as we go
Implement the full user experience across 4 main screens (journaling, reflection, memory recall, timeline)
Deliver a working, well-documented codebase + deployment-ready build
Provide handover + training so I can maintain and evolve the app post-launch

💬 How We'll Work:
I’ll provide product direction, UX flows, and desired AI behavior
You’ll bring the development expertise, execution plan, and tools
I want to learn during the process — you should be open to explaining things along the way

📅 Timeline:
The project must be completed within 4 weeks
Please include a proposed execution plan with major phases and timeline
We'll collaborate async, with occasional check-ins or pair programming sessions

💰 Budget & Cost Expectation:
Cost will be a critical factor — I'm looking for the best value, not just the lowest quote
Please be honest and realistic with your pricing
Fixed-price proposals are preferred (but open to hourly if scoped clearly)
Include a breakdown of what's included at your price

Bonus points if you’ve worked on:

Journaling, wellness, or productivity tools
Speech-to-text, semantic search, or on-device AI
Projects with a strong focus on privacy or offline UX

Let’s build something calm, meaningful, and smart — together.
Looking forward to your proposals!
