I have used many freelancers from here - some were ok, some were terrible - Stefan is easily the best developer I have found in freelancer.com.
Great professionalism, fantastic work ethic and someone I will 100% work with again. He found problems I didnt even know I had and fixed them in double quick time.
I wish I found Stefan a long time ago. He would have saved me money, my hair and my sanity!
I would highly recommend him to everyone.
I've been working on an app that sends messages across three chat platforms: Slack, Webex Teams, and Microsoft Teams.
I have implemented messages and files to receive logic using webhooks and event subscriptions.
Implemented an asynchronous long polling service to listen for chat events using React & PHP.
Assisted frontend developers with Vue.js apps and other JS + HTML + CSS tasks.
I implemented app analytics, designed a lot of complex database queries, and did some optimizations and caching.
