MAJOR PROJECTS

EMPLOYEE COMPENSATION PLATFORM
Employee Compensation Platform is a blockchain platform that is designed to improve
health, safety, and employee productivity by replacing outdated compensation
systems with token-powered smart contracts that automatically pay workers for their
contributions to business profitability. There is a web Company/PEO Admin UI and
Android/iOS employee application with microservices deployed on AWS and built
based on the newest Spring Cloud stack. For communication between services/clients
uses AWS SQS/SNS The solution rewards users with tokens for their performance,
enabling them to set and achieve personal and professional goals more accurately.
Bonuses, salary raises, and other infrequent incentives are now replaced with small,
immediate rewards paid in cryptocurrency tokens for achieving daily goals that
accumulate to make a substantial difference to the company and provide immediate
positive feedback to employees. The created solution also has built-in free mental
health counseling and orthopedic injury telemedicine assessment tool that allows
employees to get the help they need at any time. With such a solution, employers can
offer new benefits to their employees that were previously only available to large
multinational corporations. The platform not only helps employers take care of their
employees, showing them that they are truly valued, but also significantly reduces
employer costs by encouraging employees to be safer and healthier.
