Hi,
It will be my pleasure to work with you.
I use high neat and clean coding, most optmized coding, search engine friendly coding, systematic coding and so my sites are high fast to load (about 0-3 seconds) and high search engine friendly. My site are easy to upgrade later.
I have 8 years experience on magento. I worked mostly outside marketplaces but still I have some work on [login to view URL] and [login to view URL] with excellent feedback. Please see my upwork prilfe [login to view URL]
I work myself and so work quality will be high. If a company works then they will use programmers of different experience and so coding quality won't be high.
I do a lot of work to make site highest possible faster to load both on server and website sides. Very few programmers can use these. I also have strong knowledge on SEO.
I also made a lot of magento extensions which require highest level knowledge on magento.
Regards
Subir
