    I make websites faster. I optimize for speed MySQL and Magento. I work ONLY on projects related to performance optimization. What I can do for You ================ - speed up Your website (1-2 second complete page loads), - optimize MySQL server (includes complete audit, query rewriting etc.) - make Magento super fast (1-2 second complete page loads), - improve Your GTMetrix or PageSpeed score to 90+/90+ or even 100/100, - install and configure Varnish, Memcached, Redis and more, - explain everything I'm doing with Your site/server, - provide work log and reports with list of all changes I've made. I also work on other types of optimization projects - PHP code optimization (with profiler), general HTML/CSS/JavaScript optimization projects. I'm also Java developer and I can speed up Your Java code too. I can set up and tune for best performance Nginx, Apache and MySQL clusters. I've worked with small, medium and huge databases (from 1MB to 100GB of data). Who I am ================ I always work with caution, making backups before touching anything else. I'm reliable person which will work on Sunday (if needed) to make sure that Your site is up and running. We can communicate through email, Skype, phone or Google Hangouts. My English is quite good (contrary to many other freelancers I didn't hire anyone to write this text for me). I never failed on any project and I have exceptionally high repeat hire rate (at least in terms of Freelancer.com standards). How to NOT hire a freelancer ================ Even if You decide to not hire me consider those tips when choosing a freelancer - especially if You don't have much experience: - consider only freelancers who can finish their projects, the ones with 95%+ completion rate, - consider only freelancers with high repeat hire rate ( 20% or more) - if it's lower it means that his/hers clients were not satisfied with their work, - most reviews are SPAM and come from colleagues, - do not be impressed by Freelancer.com green score (the one in 0.0 - 10.0 range) - it does not reflect how often freelancer fails on project, his ratings etc. mniej
