We’re building a consumer-facing health and sleep optimization app that integrates with Apple Health data to deliver personalized wellness insights. The app is already live, and we’re now in the phase where we need to develop new features while cleaning up and refactoring existing code, there are aspects that are a mess—without a total rewrite. If you’re a builder who thrives in “build while you fix” mode, this is for you.

✅ What you will do:
• Work with the existing developer to fix the logical structure of the project
• Build new iOS features in Swift (UIKit or SwiftUI)
• Integrate and extend Apple HealthKit functionality
• Communicate with a Node.js + Express backend (hosted on Azure)
• Incrementally refactor parts of the codebase as you go
• Implement logic for personalized, AI and ML driven in-app recommendations (CoreML experience preferred)
• Work directly with the founder (experienced in startups, no micromanaging)

🧰 Our Current Stack
• iOS (Swift)
• Apple HealthKit
• Node.js / Express backend
• Hosted on Azure
• Apple + Google Sign-In
• GitHub for source control

🎯 Ideal Candidate
• 3+ years of professional iOS experience
• Strong with Swift and familiar with HealthKit
• Comfortable working with authentication flows
• Experienced balancing feature dev with pragmatic refactoring
• Self-motivated, reliable, and fast-moving
• Bonus: exposure to Node.js, Azure, or full-stack concepts

⚡️ How to Stand Out
• Show us real HealthKit or wellness app work
• Share an example where you added features and refactored simultaneously
• Be prepared to move quickly—we don’t do long interviews or fluff

To qualify, you must be VERY responsive, skilled, and communicative. Pass up this ad if you take days to respond to questions and weeks to develop basic features.

* Ability to fix CORS-related issues and cleanly deploy via Netlify
* Someone who can work with a small budget and get things done efficiently
* Bonus if you know how to manage state and frontend UX logic with minimal bloat

hello, I'm Erhan, I hope you are well. I want to help you with an AI automation. Let me introduce myself briefly.

I have been working as a real estate agent for 3 years. At the same time I manage a team of real estate agents. By the way, the company we work for manages more than 80 thousand houses. There are employees from different nationalities in the team. But we use the common language English. And we have a task to find suitable customers for the houses waiting to be rented in our database.

The automation I want to do is to list these houses in airtable or google doc. and get information about the house from the frontend of our website. (or I can add the details in airtable) When I add the pictures in google drive, the triger is triggered and posted on my facebook business profile and popular groups that I have been a member of for years. I want a single automatic response to the messages that will come to the posts. I will do the rest.

I look forward to your answer about whether you are interested or not.
