Tasks, approaches and even tools, they are always different and developing, so I rarely see the point in remembering something very specific - such as api framework or even language details. When a task is focused and repeated, I make different snippets/helper configs/cheat sheets for increasing speed and orientation. And even if I wanted to forget about something I repeat 100 times a day, I could not. When the project turns up, I unload it from my memory and upload there new data from a new area. I have a little hard-drive, if you catch my drift, but very effective RAM. These qualities help me look at the problem afresh; to check, find and implement the latest technologies and solutions for my projects. Taking into account software development dynamics, this approach seems quite logical. I know and use a lot of things, I realize I can't know everything, and I am open to wide range of proposals, especially for positions with career and personal growth. Multitasking is my strong side, though I also can perform agile and specialized tasks almost like a focused developer. But I easily compensate it with process automation, goal-orienting, perseverance and working from home where I have all the conditions I need and all the time available except sleep. I might have liked to be a narrower specialist, but the clients can't be chosen - they should be provided with a service. ps: I have 3 years + of work experience with Azure services

    I am a team player who is not only comfortable working independently, but also thrives in collaborative settings. With over 2 years of remote work experience, I have found the experience to be highly rewarding, and this is why I am seeking a new remote opportunity. I have a passion for travel, allowing me to connect with colleagues on a deeper level—something I consider vital, especially in remote work. In the face of challenges, I am never overwhelmed; I approach problems with a solution-focused mindset. My approach tends to favor simplicity, agility, and iteration. While I excel in fast-paced environments, I am equally adept at strategic planning. I am in search of a role where I can leverage my comprehensive understanding of web development and JavaScript within an agile framework. My goal is to contribute meaningfully while continuously expanding my personal and professional horizons. My best practices are SOLID, KISS and YAGNI principles are basic. I do not usually follow TDD even though I know it has its benefits for some cases but for my test, no matter the strategy you follow, is a must and I do not deliver code without it. I am used to working in high-performance teams and applying continuous CI/CD. Last but not least, I have worked in SCRUM as an agile methodology but I prefer KANBAN for most situations.

    I am a computer engineer by vocation, not by obligation. I consider myself a very curious person with many ideas, which I always try to bring to life whenever time allows. After completing my degree in computer science, I was fortunate enough to contribute to all stages of the software development lifecycle: designing and programming, managing teams, providing customer support, and realizing how important it is to listen to the user. I love learning from the community by attending talks, meetups, and other events, and when given the opportunity, I enjoy sharing my knowledge as well. Even in the workplaces I've been part of, I've always tried to encourage cross-learning. Lastly, I'd like to mention my other passion besides computer science: cooking, both enjoying it and getting hands-on in the kitchen.

    Soy desarrollador full stack con más de 10 años de experiencia en el sector. He trabajado durante años como desarollador para diversas empresas, pero sin duda lo más relevante son los 5 años que pasé como Tech Lead en mi propia empresa de desarrollo de software. He llevado a cabo, desde la gestión hasta la entrega, pasando por la implementación, más de 40 proyectos de aplicaciones web y apps móviles. Me considero especialista en capturar los requisitos y las necesidades de los clientes, y en convertir las ideas o las especificaciones en grandes productos, gracias a los años de experiencia en la empresa que fundé. Estoy emprendiendo una nueva etapa como desarrollador freelancer, en la que quiero aprovechar todo mi expertise de estos años para construir productos y desarrollar soluciones que superen expectativas. Durante mi etapa como CTO de mi empresa, siempre ponía el foco en la calidad del trabajo, y eso es, junto a mi experienca, lo que puedo ofrecer: CALIDAD, CALIDAD Y CALIDAD. Tengo experiencia en un amplio abanico de tecnologías, pero en esta estapa me gustaría enfocarme en lo que más dominio, el stack JS: Typescript, React, NextJS, React Native, NodeJS y bases de datos relacionales, con ORMs como prisma, typeorm o sequelize. Lo que me permite construir aplicaciones web o apps móviles de alta calidad con increíble rendimiento. He realizado proyectos con integraciones de terceros complejas, plataformas internas para empleados, apps disponibles en Android e iOS, pasarelas de pago como Stripe, registro de usuarios, notificaciones push, ... han sido muchos años y he hecho casi de todo, además gestionando todas las fases de cada proyecto en mi propia empresa.

    Benefits that my clients usually get: - saved 20%+ money spent on product development support through QA process optimisation (1 issue on production costs appx. an average 500$ to fix) - increased revenue by 23% due to fixed UX issues (1$ invested in UX testing gives from 10 to 100$ back) - more happy users who are not filing bugs but improvements - increased business evaluation due to high standards in QA documentation and approaches - a more focused team without tonnes of issues while development is in progress - each team member closing their area of expertise. - technical leaders are not distracted by unexpected issues in product I strongly believe the QA process in my client's product development is the king and the foundation for mature quality. My philosophy is not simply to hunt for bugs but to establish a mature QA process that identifies and prevents issues before they even reach your users.
