    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!

    ✅ To Apply, Please answer screening questions. They are mandatory for the application. Thanks

    About Client ⭐️ 0.0 • 0 reviews • United States • 7 jobs • MD

    We’re seeking a Solidity expert (bonus if full-stack) to develop the smart contract and, optionally, the full website for a PulseChain-based crypto token launch. The contract must be secure, auditable, and aligned with best practices for deflationary, tax-based tokens.

    This is a lean, founder-led project focused on simplicity, long-term alignment, and high community engagement. We’re building an incentivized marketing and rewards ecosystem, and your contract will be the foundation it runs on.

    *Scope of Work

    Primary (Smart Contract - Required):
    Write a secure, gas-efficient PRC-20 compatible contract for PulseChain (ETH-equivalent EVM). Key logic includes:

    Fixed total supply

    2% transaction tax (1% to marketing wallet, 1% to treasury)

    Buy-and-burn mechanism using % of tax revenue

    0% tax on LP adds/removes

    Anti-bot protections (cooldown or optional whitelist window)

    Immutable tax logic (hardcoded, no upgradeable proxies)

    Secondary (Optional Web Integration):
    If full-stack, build a companion DApp with the following:

    WalletConnect integration

    Voting portal (Snapshot or similar)

    Tiered bounty portal for task submissions with wallet check to verfiy holders

    Giveaway access based on wallet holdings with wallet check to verify holders

    Real-time tokenomics display on homepage

    Countdown timer and presale claim interface

    Frontend design will be provided. React preferred but not required.

    Ideal Candidate

    You have extensive experience writing, testing, and deploying production-grade smart contracts in Solidity. You understand PulseChain or EVM environments and the nuances of tax-token logic. You’ve built or audited similar community or deflationary tokens. Bonus if you can build subgraph connections or ship clean frontend integrations.

    Requirements

    You must deliver clean, commented, auditable code
    You must be fluent in English and responsive during the pre-launch period
    You must provide a clear timeline and a firm price quote
    You should be available to collaborate this week as we prepare for presale

    Budget and Timeline

    Fixed price or hourly, negotiable based on experience
    Smart contract only: $1,000
    Full-stack delivery: open to discussion
    We’re looking to hire immediately.

    To Apply

    Please include:

    A brief note on your experience with similar contracts

    Any projects launched on PulseChain or Ethereum

    Whether you can also build the frontend or integrate the provided design

    If you can build the frontend too, please show your portfolio

    Your availability this week

    Your expected timeline and pricing

    Thanks so much for your interest. Let's build something great!
