Off-site telecommute only — no on-site, no relocation.
I have a proven telecommuting track record.
Desired job type: contract
Available: immediately
Telecommute / remote only — no on-site, no relocation
Real-world experience & expertise:
- Over 15 years contract programming. This lets me hit the ground running and get up to speed on projects fast.
- Accustomed to coping with vast amounts of other programmers’ hastily written and hastily documented code, much of it cross-platform.
- Produce solid code fast by plugging known good code into projects, sourced from my extensive source code libraries, both public domain and commercial. This greatly increases reliability while speeding development, often by several weeks.
- Write code for clarity and maintainability.
- Extensive experience running projects through full life cycle. Can go into a project at any point.
- High level of GUI design expertise.
- Good phone, email, and iChat / Skype / Slack / GoToMeeting communication skills. I keep people up-to-date about project progress.
