The result was a total mess. I really sucks doing this and there is no enough space between as for i can put the solder there and make a decent work.
I'd use IC sockets and a wiring pen for that. See http://www.verotl.com/en/category/Wiring%20Systems and http://info.ee.surrey.ac.uk/Workshop/advice/grotwire/.
What soldering iron are you using? Perfboard is easy with a fine tip iron.
A "firestick"...40W is far too much for this sort of work. High chance of damaging components and the tips don't stay pointy for very long.
A 40W temperature-controlled iron, set to an appropriate temperature, would be fine.
