Vetted JavaScript developer in Spain (UTC+1)

Hii! This is Alejandra 😌 I am a **freelancer** (currently based in Barcelona, Spain) that relies on the idea of living this life doing what I love, learning and keeping myself abreast of my interests, taking challenges that make me grow up, professionally and personally, without geographical limitations. When it comes to work, I take it seriously. I consider myself with an aesthetic sensibility and focused on details, organized, responsible with my commitments and schedule, fanatic of a clean and documented code aligned with the best practices, collaborative with every cross-functional task/stakeholder (mainly UX but also quality, management, support, data analytics, product, etc), familiarized at reporting status and to work with remote and distributed team members, open to share my knowledge with others and to receive feedback. **I valorize work-life balance, cool working environment and challenges.** If I will spend many hours per day on a job, let's make it worth and have fun in the process.

Antonio G.

Vetted JavaScript developer in Spain (UTC+1)

I am a Senior Fullstack Javascript Developer with a mushroom-shaped profile. My core expertise lies in distributed systems –microservices and microfrontends– from where it radiates into adjacent fields. I am a junior-to-mid UI designer and developer, fluent in Docker, familiar with people management and AI, and able to understand the language of QA and DevOps engineers. I take pride in writing quality code that delivers value to its users and my journey to balance short-term business goals against long-term developer speed have made me a fervent believer in Agile, TDD, and constant refactoring. I am used to working independently in a fast-paced, changing environment and love ambitious problems that help me learn and grow. If you know any position that fits this description, please get in touch! ;)

Jose G.

Vetted JavaScript developer in Spain (UTC+2)

Experienced developer skilled in building high-performance web applications. Proven ability in using modern technologies like Node.js, TypeScript, NestJS, React, MySQL and MongoDB. During my time at Zegel IPAE as a Backend Developer, I had the opportunity to work on APIs for a Massive Open Online Course (MOOC) platform using PHP, Laravel, and MySQL. However, what stands out is that Zegel IPAE was my first project in Node.js, which allowed me to learn and gain valuable experience in this technology. Working with Node.js, alongside technologies like Laravel and MySQL, provided me with a strong foundation in backend development using a modern and efficient language. One project that benefited from my contribution was "App Mi Tienda" at Encora. As a Software Engineer, I designed and developed a scalable microservices architecture using Node.js, TypeScript, TypeORM, NestJS, MySQL, and GCP. My key performance optimizations, such as utilizing Cloud Pub/Sub and Cloud Functions, helped reduce load times and improve the overall scalability of the web application. My colleagues valued my ability to identify and solve complex technical challenges, which contributed to building robust architectures and optimizing performance. Additionally, they appreciated my strong teamwork and communication skills, as I actively collaborated with both the frontend and backend teams, ensuring seamless integration and successful project outcomes.

Victor F.

Vetted JavaScript developer in Spain (UTC+2)

I've been coding professionally for 15 years, the last 5 as a cofounder and director of a team of engineers that grew from 2 to 15+ people. I am passionate about programming and enjoy helping other developers, both junior and senior, improve their skills. I have mentored developers that now work at places like Google or Tesla. My experience range is full stack, with a preference for Python, C++ and JavaScript, but I have used many other technologies too. I have a PhD in Bioinformatics, and two degrees in Mathematics and Computer Science. Algorithms, math, competitive programming and biomedicine are other passions of mine, and I'd be glad to help you in those fields too.

Pablo M.

Vetted JavaScript developer in Spain (UTC+2)

Hello! I’m Pablo. One of the most lively people in the world who loves developing code that ease my life or automates tasks. Sometimes spending more time developing the code than the task itself would require. From the system32 folder to my first “Hello World!” in C to my first job. That’s my IT world journey. When my father bought our first computer, my fun was playing solitaire and trying to open all from system32 to see what happen, in that time I also had my first contact with HTML, from that to computer science undergraduate at the University of Brasília (UNB) where I did my first code in C and found that coding was my passion, was a jump. In these years I had 2 internships and for my performance on the second, I was hired as an Analyst Developer. Now with the knowledge that I acquired in the companies I’ve worked on, about enterprise development, design patterns, clean code, refactoring, and others, I’m focusing to become a Full-stack JavaScript Developer, the language that I love. But also able to work with Python, Ruby(Rails), and excited to be part of a great company!
