Hello! I want to tell You a little about my professional career growth. I have more then 18 years of experience in the field of IT. The last six years I have been working in a large company importing alcohol from different countries. To begin with, I want to emphasize that in this large company there are two big data centres where located servers (10+5) PBX server based Asterisk FreePBX, MAIL server by Kerio Connect, CRM server, Windows server 2008 R2 with domain and Active Directory with cluster, virtual server based PHP Virtualbox on Ubuntu. Also in this two data centres are located routers (Cisco, D’Link), switches (Cisco, D’Link), NAS servers (Synology) and etc. One of these two server rooms I fully implemented. I carefully selected servers from manufacturers HP Proliant and Dell PowerEdge. Using my experience as a network and system engineer I selected the optimal network equipment for this business based Cisco and D’Link. I have configured all the network equipment too (creating routes and vlans, implementig IPsec tunnels and VPN servers). I have configured two firewalls based D’Link DFL 1660 to secure network by different polices and rules. For this moment I can confidently say that I manage all the two data centers with a lot of servers and network equipment with different services and OS. Also under my personal control there are about 200 PCs. I want to emphasize that one of my huge projects during my career is the organization, implementation, full installation and support is VoIP telephony based on Asterisk FreePBX in 2017. In this direction, I am not shy to say that I took the organization out of the generation of analog telephony in the era of SIP telephony. I consider it a great achievement to convert analog numbers to a digital while preserving the number. In conclusion, I want to tell my future clients that I am deeply pleased with my work, I love working and earning and developing.

Are you stumped on how to turn your vision into a reality? If you're just starting out a business, things can feel overwhelming. I hear statements like this all the time - "Do I build a website, throw up a Facebook page, or start printing business cards?". Are you at an intermediate stage, but not having much success with your ad campaigns? You might wonder what's the point of running these campaigns in the first place. Even if your business is churning along, things get less obvious on how to increase sales for your product or service. Ironically, it's subtle tweaks that can help push your business to the next level. Irrespective of the level your business is at NOW, I'm thrilled in helping you achieve the results that you didn't know were possible. ----------------------------------- Reviews ---------------------------------------------------------------- 💥"Ryan was great to work with and is exceptional at what he does. Adwords campaigns were organized well and hit our ROI goals. Hired him for a few other projects and will do so again in the future." -- Aleks 💥"Ryan did an outstanding job with our Google Adwords and Website Strategy. His honest approach to business and experienced saved us from making a costly mistake. Unlike most Upwork Contractors, his creative thinking and passion for business is outstanding. I would definitely recommend speaking to him over the phone and you will understand the difference between his service. Thank you for saving us a huge mistake and not taking advantage of the situation!!! Will definitely use again." -------------------------------------------------------------------------------------------------------------- The first thing that you should know about me, is that I only work with clients who a. Are willing to invest in their business and will do what it takes to succeed b. Are able to articulate what their business is now, and where they want it to be c. Are focused on quality (a big pet peeve of mine) In other words, if you aren't interested in investing in your business, can't explain where you want to take your business, or you don't care if something is poorly made, please go away. There are tons of people that will gladly take your money and give you mediocre results. If on the other hand, you care about your product or service and how it impacts others, then please read on. There's usually one of three ways I work with clients. 1. Landing Pages and Funnels This is where your prospective customers will investigate your business and make the decision if they will purchase your product or service. When working with clients at this level, my goal is to help you get a competitive step up from all of the noise. Yes, design matters; the way you present your business says a lot about YOU and how the customer will FEEL with the end result. My team and I offer web services from simple landing pages to multi-tiered click funnels. 2. Digital Advertisement Do you need sales in the next few weeks, even days? This is a great way to start funneling prospective customers to your business in a short period of time. As part of our services, we can work at any stage of the funnel for your business, to exploratory market reach, to extremely specific actions, where the customer knows exactly what they want. We offer ad services on Facebook, Google, LinkedIn, Youtube, or other places if you have something in mind. 3. Search Engine Optimization Yes, everyone loves the idea of being the first result on a Google search result (without paying a dime), but it turns out there's a TON of competition eyeing for that same spot. When it comes to SEO, my team and I will help you optimize your website to start ranking higher on various search engines. While this is something that we can implement in a short period of time, SEO is a medium to a long-term strategy that takes time to see results. If you have unrealistic expectations such as "By tomorrow I want to rank #2 for NY patent attorneys", please consider ads instead. My team and I bring a unique approach to marketing your business. I have a formal background in computer engineering/systems. This means that I'm quantitative with my approach, and tend to be data-driven when thinking about your business. I've worked at several Silicon Valley startups, and run my own tech startup. I've also been involved for 10 years in broadcasting media & design, and have worked with student groups in college by helping with digital and guerilla marketing. If you have any questions about our services or want to get a dialogue going, feel free to reach out and I'll get back to you about your business needs.
