Marcos Baravalle
Fullstack Web Developer
about:
I'm a Full Stack Engineer based in Argentina, with over three years of experience building web applications, SaaS platforms, and custom software. My daily tools are TypeScript, React, Node.js, NestJS, and PostgreSQL, and I've worked through the whole life of a product: from architecture and API design to deployment and the maintenance that comes after.
On the frontend I build scalable applications and spend a lot of time on UX and visual detail, using GSAP and Three.js for interactions that go beyond the standard template. On the backend I design REST APIs, work with PostgreSQL and MongoDB, implement authentication systems, and use tools like Prisma, TypeORM, and Docker to keep things organized.
At Notimation I helped ship two AI-powered products, UiTool and UiTrade. That meant owning frontend architecture, integrating chatbots, and carrying products from idea to launch in a fast-paced startup environment.
Through Abstract I delivered more than ten production projects across different industries: SaaS platforms, custom management systems, and high-performance marketing websites. Each one came with its own constraints and technical problems to solve, which is the part I enjoy most.
I care about code quality, maintainability, and scalability, and about building software that provides real value to the people who use it. I'm always open to interesting projects, technical discussions, and new opportunities.
