Wanna see yourself on below list of clients I helped to earn few millions? Send me contract offer today! After working with me, clients usually get a feeling there is nothing I can’t do, and start throwing at me tasks requiring multiple skills I don’t have (which I pretty much always deliver) Indeed, “I can do all things through Christ which strengtheneth me.” (Philippians 4:13) but for most years I was programming, I was gaining experience with Javascript (React.js/Next.js/Node.js) and PHP (Symfony/Laravel/Wordpress) Last year I’m mostly working on Blockchain projects forking/fixing/auditing and integrating smart contracts into web applications frontend and backend. I was never smartest / most experienced / most educated guy around, so for 28 years I’ve spent programming (18 as primary income) I’ve been cultivating persistence, performance and love for challenges, which allows me to consistently deliver complex tasks, others are scared to even try or give up too soon. Of course, success is always an effort of entire team, but it wouldn't be too much of an exaggeration to say that, with God’s help I was the guy who made it possible - For Mobillogix to get MVP developed and shown to potential investors in about a month, get $4.5 million in a seed round (public data), and partner with companies like Samsung and AT&T (Fortune TOP20 at 2017) - For FindCashBuyersNow to get an unfair technological advantage, get US real estate market domination and receive gazillion (not authorised to disclose actual figures) USD for capital management - For Logan Paul to raise $3.5M (public data) after selling his Originals NFT collection - For Amnext to acquire above $0.5M market cap (public data) few days after the launching their DeFi - For BoomBoomNaturals to prepare their Shopify store to be ready for the date of being shown at Shark Tank episode ( youtu.be/K8cR6nn2_s4 ) and receive gazillion (not authorised to disclose actual figures) USD in sales Can’t list here all projects, but here is feedback I got from 2 of TOP100 Upwork clients (those who spent on Upwork more than $1M) after working with them for a few years: - #1 developer on Upwork. Having spent close to $200,000 with him on several projects, I am extremely happy and satisfied with his work... He is the kind of developer who takes on challenges and projects no one else can solve and with deadlines that are extremely difficult to achieve. He is worth every penny and more because he gets the job done every single time without any excuses or delays. Anyone who has the opportunity to work with Dmitry should consider themselves lucky as in all my years in Upwork, I haven't found someone as talented, patient and hard working as him as he never complains about how complex a job is, how tight the deadlines are or the fact that majority of the time he is solving the problems/bugs caused by other developers halfway towards the finish line of the project... - ... one of the best developers you can find, he is extremely smart, highly skilled and many web technologies, quick learner, friendly, business focused and result focused. I highly recommend Dmitry to anyone looking to hire someone that can get the job done If that wasn't enough, to save you from scrolling through hundreds of jobs, I've picked few more: - in 7 years of continuously using freelancer websites this experience stands out as being exemplary ... most professional manner possible. 6 stars - I am rarely impressed, but I was impressed! Senior Google/Facebook level of expertise truly unbelievable. - I don't know how Dmitry managers to do what he does, but he is far and above the most communicative, qualified and efficient developer I have worked with here - Wow how you do that so easily, GENIUS! - Dmitry truly is brilliant at programming. Many people say they are rockstar programmers but he truly is a rockstar - Truly a PHP ninja and a rock star developer - The fastest and more competent PHP developer I found on oDesk! He's really the "fastest gun in the west" - It is not a human! - This guy is a wizard - Dmitri is truly as talented of a developer as everything (including himself) says he is - I would pay a much higher hourly rate for his services. He is faster than any other contractor I've worked with here and he gets the job done correctly - This guy is awesome. Period
