    My interest in programming started early and I began getting to grips with coding from the age of 16. Since then I have not looked back and have dedicated my career to full stack software development. When it comes to my work ethic, my motto is that there is nothing impossible. I always look for the best solutions for my clients. Currently as a lead architect I am responsible for connecting my client with the right developers as I help to translate client thoughts into actual projects. As a full stack engineer I am used to working with both the front and back ends of a website or applications and tackling projects that involve databases, building user-facing websites while also working with clients during the planning phase of projects. As my colleagues often joke if you need the impossible done quickly then get in touch. I would be happy to discuss how we can move your IT project forward and find the best solution to fit your business model. Skilled in C#, Integration, SOLID, Software Development, JavaScript, and SQL.

    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.
