    Hi! I am fullstack web developer from Lithuania, with 8 years of web development experience. I specialize in programming with PHP, Node.js (Typescript/Javascript) and I also do frontend jobs. I also have some experience in cryptocurrency and I can program Solidity/Web3 apps. I also know how to use AWS and I have built various servers since I was 11 years old. I had my website at that age. At 14 years old I owned a CS 1.6 server and sold admin rights to other kids. Then it was hacked. Now I am 28 and already built a bitcoin node. It wasn't hacked :) And also Docker. During my career I worked on a lot of websites, with various tools, but now I am working mostly on dashboards and APIs. I have a good knowledge about "what's on the market" and I am not afraid to use new tools, but that doesn't mean that I do not depend on time proven solutions. I am a great believer, that every situation and every project demands good understanding "what needs to be done", and I always try to find the best tools for every single project.

    I am an integration specialist who can connect different services! My main specialization is automation using Make (formerly Integromat) I have knowledge in: *Microsoft office products; *Webservices, API (RESTful); *SFTP, file management; *File transformation, structuring (XML, JSON); *HTTP(S) requests; Why do I specialize in Make? Because it is very easy to use, and maintain and you have full control of processes. Make has a very big variety of modules already implemented (like Calendly, Zoho, HubSpot, Xero, and more..) and in this way, I can get the job done very fast and in the best possible practice.

    I’m a Senior Software developer, having +10 years integration development and design experience using MS product technologies, mainly focused on MS Dynamics CRM, .NET, C# code language, BizTalk applications and Web services. Participated in maintenance and “greenfield” projects in telecommunication and financial industry sectors, I feel comfortable working independently or in the team with minimal supervision in heavy workload, challenging tasks or critical environments. Experienced in Test Driven Development, Unit Testing and mock frameworks, I concentrate on producing high quality code and deliver it on time.
