Before you hire
Questions, answered
Are you open to full-time roles or contract work?
Both. I'm open to full-time senior full-stack roles and to contract builds of a product or platform.
Where do you work from?
Lisbon. I work remotely on European hours, or hybrid or on-site in Lisbon. Roles that need US-only hours or a move away from Lisbon aren't a fit for me.
What happens to SharpHaw if you join a company?
SharpHaw becomes a small side studio with a few clients, run mostly on SharpOS, the platform I built for it. The job gets my full working hours. If your company doesn't allow any side business, raise it in our first conversation so we settle it early.
What do you charge?
I don't publish rates. I share salary expectations or a contract rate in our first conversation, once I know the role or the scope.
Do you build websites for small businesses?
My studio does. SharpHaw runs websites, ads, content and automations for small businesses across Europe.
Tell me what you're building.
One message is enough to start. I read every one myself and reply within 2 business days.
