Job Description: Web Developer for Customizing Open-Source PWA
Company: Emilo Labs
Project Type: Progressive Web App (PWA) Development
Job Type: Freelance / Contract
About the Project:
We are building a progressive web app (PWA) where users can sign up, complete daily check-ins, and perform tasks to earn points. The points system will be non-redeemable at first but will later transition into a utility token system. We will be using an open-source project (e.g., Open Loyalty) as a base and customizing it to fit our needs.
We need an experienced developer to customize the open-source code, integrate fraud detection to reduce bot activity, and ensure a scalable and secure platform.

Why are lot's of people saying negative things about #PiNetwork pi coin today?
It's simply because Many of them knew when it started, they mocked people that were mining then and now they want to make themselves feel good by trash talking the project. Jokes on them 😂😂😂
If they really don't care about pi, why spending soo much time trash talking it? "If we can't have it let's spoil it for the people who do" 👈🏾 that's their mindset.
