Hello, I hope you’re well. I’m building an emotionally intelligent chat product using Bubble and OpenAI GPT-4o, with a Webflow landing page already designed. I’m looking for someone who can help connect the front-end flow with the Bubble experience while keeping the emotional tone and user journey consistent.

Here’s what I’m trying to build:

First, I need the Webflow CTA to lead smoothly into the Bubble app. The flow should start with login or signup, then take the user into the chat. I’d like the transition to feel clean and natural, not like two separate tools stitched together.

Second, I want to use OpenAI’s Assistants API. There will be one Assistant for the app, and one Thread per user. This is where we’ll store memory and emotional context. You should be comfortable managing threads, storing metadata, and retrieving past conversations. I don’t want to use OpenAI’s built-in memory system — I want something structured that we can control inside Bubble.

Third, I’ll be giving you emotional tone prompts and fallback logic. These should live in Bubble’s database so I can edit them later without needing development help. That includes the main system prompt, soft re-engagement messages, and tone cues.

Fourth, I’ll need a basic admin view where I can see active users, premium status, and message count. If we can include optional message logs or summaries later, great.

I also want to set a daily message cap. Free users get ten messages total. After that, the input should be disabled and a soft message should prompt them to upgrade. Stripe integration will come later.

Lastly, I want this to be future-friendly. Later I might want to add voice messages, emotional tagging, or re-engagement flows for inactive users. So I’m hoping to build this with scalability in mind, even if we keep the MVP light.

If this sounds like something you can take on, I’d love to hear your thoughts and how you’d approach it. Let me know what you’d need from me to get started, whether you’ve worked with OpenAI Assistants and Bubble before, and a rough time or cost estimate.

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!

We have an application called the NIHSS Virtual Doctoral School. A collaboration system for academics. Think of it as a Facebook for people doing their PHd. It uses Open Source Social Network and Flutter for its stack. The project has fallen behind and we need a new team to take over and finish the project. I have attached the project plan and deadlines.

I’m seeking a talented web developer (or small team) to build a modern, user-friendly web application that lets users track and redeem “brownie points” with each other. The concept is similar to a chore or task tracker, but designed for couples or small groups to encourage positive interactions and reward one another.

Key Features & Requirements:

User Groups:
Users must be able to form groups (e.g., husband and wife, roommates, friends) and interact within their group only.

Task Posting & Negotiation:
Users can create tasks with a point value and assign them to a user in their group, which the other member can negotiate or approve before they appear on the task board.
(e.g., “Take out the garbage – 3 points”; the other user can suggest a different value before accepting.)

Recurrence & Redemption Settings:
Tasks can be set as one-time, repeatable (infinite), or limited to a certain number of completions.

Notifications:

When a task is posted, the user assigned is notified.

When a task is marked as done, the user that assigned it is notified for approval.

The assigner can add a bonus (percentage or fixed value) upon completion approval.

Points & Rewards System:

Points are awarded for approved tasks. Rewards can be created by the person wanting the reward, or by the person offering the reward. Approval is needed either way by the other user.
Users can redeem points for rewards created by the other person.
When a reward is redeemed, it’s added to the responsible person’s TODO list.

Media Attachments:
Users can attach images, videos, or audio to completed tasks. These should be viewable in-app (not as downloads).

User Flow Example:

Wife posts: “Take out the garbage” (3 points)

Husband approves task

Husband completes and marks task as done, and uploads picture proof

Wife confirms completion, points awarded

Husband redeems “Foot rub” reward

“Foot rub” is added to wife’s TODO list

App Pages:

Login/Register: Secure account creation with encrypted passwords

Dashboard: View users points, see/approve pending approvals
Links to: create tasks, view tasks assigned to you, view TODO, View rewards, create rewards, view completed tasks that you assigned (Spot to view attached media)

Create Task: Name, description, point value, recurrence settings

Available Tasks: List and view details of tasks to complete

TODO: Rewards the user needs to fulfill

View Rewards: Rewards available to redeem

Create Reward: Create new rewards for other group members (Title, description, point cost, recurrance settings)

Technical Considerations:

Frontend: Clean, modern, mobile-friendly UI (specify your preferred framework in your proposal)

Backend: Python preferred (Flask, Django, or FastAPI), with split Python and HTML files for each feature

Data: Must work over both mobile data and WiFi. Include nginx files as needed

Security: Encrypted passwords and secure authentication

Hosting: App will run on my Unraid server with a publicly accessible domain and ample storage

Notifications: Served by any free push notification service that works on android. FCM, Pushbullet, etc.

Bonus:

Experience building similar task-tracking, habit, or reward apps

UI/UX design skills for a modern, friendly interface

Delivery expectations
All necessary script and html/js files packaged ready for deployment
