You have a sharp IT team. You could save a lot of time and money (and quite possibly some costly oversights) if someone would just solve a specific problem or deliver working code.
You need a specialist for a temporary work assignment, to get something done, so your team can resume progress.
Describe your project and find a specialist who will get it done.
You’re a pro. You know everything there is to know about your favorite language, best practices, specific apps. You can help people.
Your greatest value is in sticking to what you know best. You want to diversify your income by extending a helping hand or even go all in and become a full-time contractor.
Describe your skills. Be specific. Project Owners are searching for exact skills for specific opportunities. Peruse the project boards. Set your own terms. Work when you want.
