    Hi! I'm Ed, your freelance Netsuite Administrator/SuiteScript Developer with 6 years of experience. You won't regret it if you choose me as your freelancer. Skillset: • JavaScript • HTML and XML • REST • SOAP • SQL • Web Services • SuiteScript 1.0 • SuiteScript 2.0 • SuiteTalk • SuiteFlow • SuiteBuilder • SuiteAnalytics Connect • Saved Seaches, Reports KPIs SuiteScript is my favorite Netsuite feature. It allows you to modify/customize every aspect of Netsuite. I enjoy writing scripts, and I don't feel that I am working every time I work on a project. I can see SuiteScript as a mental exercise, more like a challenging puzzle to solve. I have an incredible feeling of accomplishment every time I finish a project.

    I've been working with IT since 2009 and during my trajectory I realized that the most important thing between a customer and supplier relationship is trust. In these years of experience, I worked in website development, script development for servers and network administration. I also managed several projects in the technology area and that's why I can keep my work organized. At my college, I learned several programming languages, worked with some databases, but my focus is currently developing applications with Bubble.

    I specialize in designing and building Vue/Nuxt projects, ranging from landing pages and websites to digital artwork and open-source libraries. I'm lucky to say that I really enjoy what I do, so it never feels like work. I'm drawn to projects that demand quality workmanship — favoring unique designs, micro-interactions, animations, and meticulous attention to detail. Whether I'm involved early in design and prototyping, or later in production, I'm constantly thinking from the perspective of the user, making sure that I'm putting something out there that people can actually use. Over my career I've had the opportunity to collaborate with some amazing teams of talented people, from emerging startups to established digital agencies and multiple Fortune 500 companies. My current focus is on partnering with agencies, supporting their in-house teams, leading projects, and delivering best-in-class work for their clients.
