I started at Upwork and was constantly writing proposals and struggling with the search to find relevant jobs.
But on Toptal, even after an abrupt end of the contract I get something else in less than a week and it's zero effort from me and all effort from the Toptal team.
Even if I get bored and want a change, announcing the end of contract turns on the avalanche of offers from the Toptal team.
It's just insanely smooth and I had no idea I'd find something like that, initially.
