Efficient API Integration for Freelancers

I need an informational website that pulls live financial data from an external API and presents it in a clear, engaging way. The core of the build revolves around two key features: interactive data visualization—think real-time charts, graphs, and summaries—and a secure user authentication flow so visitors can create accounts, save their preferred views, and return to personalized dashboards.

The API you choose must reliably deliver up-to-the-minute market figures (prices, indices, or similar). I’m open to suggestions on specific providers as long as the solution is well-documented and cost-effective. Front-end responsiveness is important; the site should look good on desktop and mobile alike. A lightweight admin panel or clearly commented configuration file is also needed so I can adjust endpoints or keys without digging into core code.

Deliverables
• Fully functional website deployed to my hosting environment
• Clean, well-structured source code with README explaining setup, API credentials, and environment variables
• Interactive financial charts/graphs fed by the live API
• Secure registration, login, and session management (JWT or similar)
• Basic styling that matches a modern fintech aesthetic

Acceptance criteria: if I can log in, select a financial symbol, and watch the chart update in real time, the job is done.

Skills: PHP, JavaScript, Website Design, CSS, HTML, Web Development, Data Visualization, API Integration

I’m building a scalable AI receptionist product for restaurants / fast-food businesses in FRANCE

IMPORTANT:
I am NOT looking for a one-off automation or a custom build for a single client.
I am building a REPLICABLE system that I will duplicate for dozens of clients.

If you usually build one scenario per client → this job is NOT for you.
Build ONE demo system that can be duplicated in less than 15 minutes for each new restaurant.

The system answers phone calls with an AI voice agent in French, takes orders, and sends structured data to internal tools (Notion + SMS).
- Make.com (webhook-based architecture)
- VAPI (or similar Voice AI platform)
- Twilio (SMS notifications – voice number already handled by me)
- Notion (database template – universal layer)
1) Receive structured data from a voice AI agent (webhook)
2) Process and format the order in Make
3) Create a new entry in a Notion database (template)
4) Send an SMS notification to the restaurant
5) Be fully parameterized (restaurant name, phone number, database, etc.)
6)If its possible, integrate directly in the screen or logicial of the restaurant

NO Zapier
NO proprietary CRM
NO per-client rebuild
NO hard-coded values

What you do
New client setup time must be under 15 minutes:
- Duplicate scenario
- Duplicate Notion database
- Change variables
- Done

What you don't need to do
- Buying phone numbers
- Client billing
- Final production credentials

You will work inside my infrastructure with limited access.

Perfect profile
You are a good fit if:
- You have built Make.com systems using webhooks
- You understand scalable / SaaS-like architectures
- You have worked with Voice AI, IVR, or conversational AI
- You think in templates, not custom builds

Budget
Fixed price: $150 – $300
(depending on experience and documentation quality)

Quiero impulsar mis ventas en Amazon FBA con una estrategia de marketing bien estructurada y, al mismo tiempo, automatizar los procesos de inventario para evitar roturas de stock.

En la parte de marketing, necesito un plan que combine research de palabras clave, optimización PPC, promociones y ajustes en listings ya existentes para mejorar la conversión. Me interesa entender qué campañas lanzar, cómo distribuir el presupuesto diario y cuáles métricas revisar para ir afinando la inversión.

Respecto al inventario, busco implementar flujos automáticos: alertas de reposición, sincronización con el almacén y reglas que ajusten niveles de reabastecimiento de forma predictiva. Si trabajas con herramientas como Amazon Seller Central, Sellerboard, RestockPro o integraciones vía API, mucho mejor.

This phase is strictly focused on ONE task only: flipping (buy → evaluate → list → track).

This is not a vague idea and not a full system.
I am hiring someone who can build clean logic and reliable workflows, not flashy demos.

⸻

Objective (Read Carefully)

Build a working voice-based assistant that can:
• Converse naturally via voice
• Maintain basic memory across conversations
• Own ONE task end-to-end: flipping evaluation and listing support

Anything outside flipping is conversation only, not execution.

⸻

Scope – What You Will Build

Core (Required)
• Voice input → AI reasoning → voice output
• Calm, professional “British butler” tone
• Persistent memory with permission-based saving
(assistant asks before remembering non-essential info)

Flipping Task (PRIMARY)

The assistant must be able to:
• Ask required questions (buy price, condition, platform, demand)
• Calculate:
• expected resale
• profit
• margin
• basic risk
• Give a clear YES / NO recommendation with reasoning
• Generate a ready-to-post product listing
• Track flips with simple status (sourcing / listed / sold)

Example behaviour:

“At this price, sir, the margin is insufficient. I would advise against proceeding.”

⸻

Non-Negotiables
• Milestone-based work only (no full payment upfront)
• Access to the project must be provided after each milestone
• Clear communication (short updates are fine)
• If you disappear, the contract ends immediately
• Overpromising = automatic rejection

⸻

Application Test (IMPORTANT – FILTER)

To apply, answer ONLY these two questions.
Do not copy-paste the job description.
1. How would you structure the flipping decision logic so the assistant can confidently say yes or no?
2. How would you handle memory so the assistant remembers important things but avoids storing everything?

Applications that skip this will be ignored.

⸻
Budget

$1,000 total, split into milestones.
This is a prototype, not a production system.

If Phase 1 is done well, there will be follow-up work.

⸻

Final Note

I value clarity, discipline, and logic over speed or flashy features.
If you enjoy building systems that actually work, this will be a good fit.

About TradeBoost
TradeBoost is a growth partner agency for home-service businesses (painting, renovations, fence/deck builders, etc.). We manage ads, CRM systems, and ongoing website improvements that support lead generation and conversions.

This role is not about full website redesigns. Most of our work is building new pages on existing sites and making sure they load fast, work properly, and integrate cleanly with our systems.

What You’ll Be Responsible For

You will support multiple client accounts by building and maintaining pages across different platforms.

This includes:
Building new pages on existing websites (service pages, location pages, landing pages)

Editing and improving existing pages without breaking live sites

Ensuring all pages are:
Mobile responsive
Fast loading
Clean and maintainable
Integrating forms with CRMs (primarily GoHighLevel)
Installing tracking pixels (Meta, Google)
Basic troubleshooting and bug fixes
Following SOPs and build standards provided by our team
What We’re Looking For
This role is for a strong generalist web developer, not a designer and not an SEO strategist.

You’re a good fit if you:
Have hands-on experience building pages across multiple CMS platforms
Are comfortable jumping into existing sites and making changes safely
Can execute quickly without constant back-and-forth
Understand front-end fundamentals (HTML/CSS)
Communicate clearly and hit deadlines

Nice to Have (Not Required)
Experience integrating websites with CRMs or marketing tools
Basic understanding of page speed and Core Web Vitals
Experience working with service-based or local businesses

What This Role Is NOT

Full website redesigns
Branding or logo work
Graphic design
UX research or strategy
App development

Expectations
Fast turnaround on page builds
Clean, reliable work that doesn’t need constant fixing
Ability to follow documented processes
Long-term mindset and availability

Compensation
Hourly or per-page pricing (based on experience)
Consistent ongoing work
Opportunity to grow with the agency as we scale

How to Apply
Please include the following in your application:
Which platforms you’ve built on in the last 12 months
Examples of pages you’ve built on existing websites
