I had been working as an independent contractor for more than 3 years. Apart from the ones mentioned above, I have worked on numerous projects; but admittedly I have tended to choose projects with a relatively smaller scale, due to the intermittent nature of my availability as I was also continuing my college studies alongside this. I’m not currently looking for any freelance work.

  • Support standard headers like CC, BCC, Reply-To and Authors.
  • Supports injecting custom headers.
