I'm a skilled Full Stack JavaScript Developer with over 7 years of experience building modern web and mobile applications using technologies like React, React Native, Node.js, AWS, and PostgreSQL. I specialize in developing scalable, maintainable, and secure applications that solve real business problems and deliver great user experiences.
Over the years, I’ve worked with both startups and established companies across industries like Web3, risk management, and SaaS. At Pizza Wallet, a Madrid-based Web3 startup, I contributed to three separate projects, helping the team improve code maintainability, integrate third-party modules, and develop scalable frontend solutions using React and modern JavaScript practices. I also worked closely with microservices, collaborating with internal teams to integrate internally-developed modules with efficiency and reliability.
During my time at DNV, a global assurance and risk management company, I was responsible for building both frontend and backend features across multiple projects. I worked closely with designers and product teams to turn ideas into working software, facilitating technical discussions, performing code reviews, and ensuring we shipped high-quality code on time. My responsibilities included building secure APIs with input validation, writing maintainable backend logic in Node.js, and building rich, interactive interfaces with React and Typescript.
One of my recent projects involved launching a mobile application built with React Native, integrating A.I., using AWS Lambda for serverless backend functions and PostgreSQL as the database. I handled both the frontend and backend of the app, making architecture decisions, writing efficient cloud functions, and optimizing data handling for performance and cost. This experience gave me hands-on insight into building cross-platform mobile apps backed by scalable serverless infrastructure.
I’m comfortable working in fast-paced, agile environments and enjoy collaborating with cross-functional teams. I have a strong ability to reverse engineer and understand complex or legacy codebases, which helps me quickly onboard to new projects and contribute meaningful improvements right away. I take pride in writing clean, readable code and following best practices, including code reviews, test-driven development, and continuous integration.
Beyond code, I bring strong communication skills and a proactive approach to every project. I believe in understanding the “why” behind every task, which allows me to make thoughtful technical decisions that align with business goals. Whether you're building an MVP, scaling an existing product, or integrating new features, I’m here to help you move faster with confidence.
If you’re looking for a reliable, communicative, and experienced full stack developer to bring your product to life—let’s talk!
