Maybe instead of just saying that you have developed "iOS apps" you should at least also say what their names are so that the members especially the OP will know what you have really developed. Not only will it save us time but it will also help what you are pitching him. Instead of just backing it up with your blog post what you should include is the project portfolio you have which will also be helpful. I'm just saying this because most the low ranking members here ranging from jr. members to newbies in the project development always try to offer their service but what they forget is to post their credentials with their previous works backing them up.
Look I appreciate your advice and that I'm only a junior member here, but I'm literally one of the first people worldwide who have successfully started iOS apps development professionally and we've built hundreds of apps literally, some banking apps for Barclays, TCS, multiple apps for Hollywood studios accompanying top movie releases such as Avatar etc, a number of healthcare and telemedicine apps, Liverpool FC and Man City FC fan apps etc, gaming (iCombat etc), multiple featured by Apple in some demonstrated in WWDC events. There isn't much point to list all of them and some are protected by NDA. Will be happy to share more details with clients and there is no point to bore others with details here.
Not really focused on pitching someone here, it just so happened that I've checked this forum, not doing it every day, more like once every 2-3 weeks and I saw someone looking for help on their project which matches exactly my personal and my company expertise, so decided to provide some details to help them potentially, and if this leads to a great client - developer match, isn't this what topic starter was looking for?
