Senior Full Stack & AI Engineer | I Lead a 30-Dev Team

Twelve years writing code, two of them running product at MotionArray, where I led the team through its acquisition by Artlist in 2020. I build the thing, I know why the business wants it built, and when the work outgrows one person I have 30 engineers behind me. Most profiles here offer one of those three. What I do hands-on Frontend and full-stack in Angular, Vue, React, Next, Nuxt and Capacitor, with Node, Laravel, PHP and C# behind it. Shipped and maintained bikeflights, skilltrakker and myhrconfidant . Comfortable in codebases somebody else wrote and abandoned, which is most of what I get asked for. AI, specifically I'm a founding engineer at BuildBetter.ai, an AI product platform used by B2B teams that turns call recordings, tickets and support conversations into structured, cited deliverables. The work is the unglamorous part of shipping AI: retrieval over a company's own documents so answers are grounded instead of plausible, structured extraction from messy input, and the evaluation and cost work that decides whether a feature survives real usage. Most products don't need a model, they need the right context reaching one. I'll tell you which you're dealing with before you spend money finding out. The team behind me I founded and run Roraima Devs, a U.S. LLC with 30+ engineers across the U.S., Colombia, Argentina, Venezuela and the Dominican Republic. 15+ clients, many with us 3+ years, 9 years on Upwork, 6 years as a U.S. company. Reviews under Roraima Devs on Trustpilot. What that means for you: I take the work I can do well myself, and when a project needs frontend, backend, mobile and DevOps moving at once, I can staff it in parallel instead of stretching one timeline into six months. You decide which shape you want, and you always know exactly who is touching your code before it happens. Larger scopes can run through the agency contract if that suits you better. How I work I ask questions before estimating. If your idea has a cheaper path than the one you arrived with, I'll say so on the first call. If I'm not the right fit, I'll say that too. Start with a 30-minute call and we'll look at what you have.
