Nexora AI Ecosystem: Full Stack Developer Needed

AI / Full-Stack Developer Needed — Nexora Personal AI + Connected Device Ecosystem MVP (£800/Month)

Budget: £800 GBP per month
Initial contract: 3 months
Potential: Long-term development relationship
Work: Remote
Project: Early-stage consumer technology / AI ecosystem

Job description:

I am the founder of an early-stage UK consumer technology company called Nexora Technologies.

I am developing a connected technology ecosystem consisting of AI software, headphones, a compact AI desktop computer, monitor and eventually a smartphone.

I have attached original concept images showing the proposed Nexora ecosystem, products and user interface. These images are concept references and should be used to understand the direction of the project.

I am NOT asking for all hardware to be engineered for £800/month.

This Freelancer project is specifically for development of the first working Nexora Personal AI software MVP and the software foundation that could eventually connect the wider ecosystem.

My development budget is approximately £800 GBP per month, so the project must be developed in clearly defined stages.

The Nexora vision

The eventual ecosystem is intended to include:

Nexora Personal AI — permission-based personal AI assistant
Nexora Hub — account, preferences and connected-device layer
Nexora Core — compact AI desktop
Nexora Pulse — future ANC/AI headphones
Nexora E1 — wired in-ear headphones
Nexora Display — monitor
Nexora One — future AI smartphone

The long-term idea is that a customer’s Personal AI can eventually follow them across Nexora devices while the customer controls what information is remembered and what devices the AI can access.

Phase 1 — Personal AI MVP

The first deliverable should be a polished desktop application demonstrating the Nexora concept.

The main dashboard should include:

Ask Nexora
Conversational Personal AI interface.

Listen
Audio/music section and future headphone integration area.

Learn
Educational assistant where users can ask questions, receive explanations and eventually access lessons.

Create
AI-assisted creative workspace.

Communicate
Future communication tools.

My Day
Tasks, reminders and daily information.

Focus
Focus timer and distraction-reduction interface.

Devices
Device-management screen showing Nexora Core, Pulse, One and other future devices.

The application should have an original Nexora visual identity based on the attached images.

Do not copy Apple, Microsoft, Google, OpenAI or another company’s UI.

Personal AI

The developer should integrate an established LLM API initially rather than attempting to train a foundation model from scratch.

The architecture should make it possible to change AI providers later.

Required functionality:

• Natural-language conversations
• Conversation history
• Streaming responses
• New conversation
• Search conversations
• Rename/delete conversations
• User preferences
• Permission-controlled Personal AI memory
• Basic tool/function calling architecture
• Error handling
• Usage controls
• Secure API-key handling

The AI should have a configurable Nexora system/personality layer.

Personal AI Memory

Privacy and user control are extremely important.

Create a dedicated:

AI Memory & Privacy

screen.

Users should eventually be able to:

• See what the Personal AI remembers
• Add preferences manually
• Edit remembered information
• Delete individual memories
• Clear memories
• Disable memory
• Decide which categories can be remembered
• Control whether information synchronises between devices

The software should never secretly collect information.

Nexora Hub

Build the initial Hub/database architecture for:

User account
Profile
Preferences
AI settings
AI memories
Devices
Device permissions
Conversations
Learning progress
Notification preferences

For Phase 1, physical devices can be represented using simulated/demo devices.

Example:

Nexora Core — Connected
Nexora Pulse — Demo Device
Nexora One — Future Device

I want the investor demonstration to show how the ecosystem could eventually operate without falsely claiming that unfinished hardware already works.

Headphone software demonstration

Create a simulated Nexora Pulse control interface based on the attached product concept.

Controls can include:

ANC

Transparency

Normal

Sound Profile

EQ

Battery

Connected Devices

Personalised Audio

Head Tracking — Future Feature

For the MVP these controls can operate against a software simulator/mock device.

Actual Bluetooth/ANC firmware integration will be a separate engineering project once functional hardware exists.

Accessibility

Accessibility is central to the Nexora concept.

Please include:

• Adjustable text size
• High-contrast option
• Reduced animation/motion
• Keyboard navigation
• Clear navigation
• Simple interface mode
• Adjustable notification intensity
• Optional reduced sensory interface
• Screen-reader-friendly controls where practical

Do not make medical-treatment or diagnostic claims.

Suggested technical architecture

I am open to recommendations, but one possible architecture is:

Desktop
TypeScript
React
Tauri

System/native functionality
Rust

Backend
Python
FastAPI

AI/ML
Python

Database
PostgreSQL for cloud/server
SQLite locally where appropriate

Authentication
Secure OAuth/OIDC-compatible architecture

API
REST/WebSocket where appropriate

The code should be modular so future Android, web and hardware applications can communicate with the same backend.

Future Android smartphone

Do NOT build a complete smartphone operating system during Phase 1.

Instead, structure the backend/API so a future Android application can connect to:

Nexora account
Personal AI
Memory
Preferences
Learning
Connected devices
Nexora Hub

Future Android development will likely use Kotlin/Jetpack Compose.

Future headphones

Do NOT attempt to develop ANC DSP algorithms without the actual headphone hardware/chipset/SDK.

Future Nexora Pulse development may require:

C/C++ firmware
Bluetooth SDK
DSP
ANC algorithms
EQ
OTA firmware
Device protocol

That will be a later hardware/software engineering project.

Investor demonstration mode

I specifically want an attractive Demo Mode suitable for investor presentations.

Demo Mode should demonstrate:

User signs into Nexora
→ Personal AI welcomes user
→ user asks Nexora something
→ AI responds
→ AI recalls an approved preference
→ user opens Devices
→ Pulse appears connected
→ user changes simulated ANC mode
→ user opens Focus
→ starts Focus Mode
→ user opens Learn
→ asks an educational question
→ Nexora answers
→ user views AI Memory
→ user can see/delete stored preferences.

The demonstration should look polished enough to record for an investor pitch video.

Intellectual property

Before starting, I will require an NDA/IP agreement.

All custom work paid for under the project should be delivered to me, including where applicable:

Source code
UI files
Database schema
API documentation
Build instructions
Design assets created specifically for the project
Technical documentation

The developer must not reuse confidential Nexora materials or proprietary project assets for unrelated customers without permission.

Please identify any third-party/open-source components and their licences.

£800/month budget

Please do not bid if you expect £800/month to deliver the complete final ecosystem immediately.

I am deliberately developing this incrementally.

A possible first three-month structure is:

Month 1 — £800

Application foundation
Nexora UI/design system
Login/profile
Main dashboard
Ask Nexora
LLM integration
Conversation interface

Month 2 — £800

Personal AI memory
Privacy controls
Nexora Hub backend
Device management
Simulated Nexora Pulse
Focus Mode

Month 3 — £800

Learn
Create
Accessibility controls
Investor Demo Mode
Bug fixing
Documentation
Packaged desktop demonstration build

Initial software budget: £2,400 across three months.

If development goes well, I would like to continue at approximately £800/month and progressively add functionality.
