    My passion is making ideas come to life, be it working solo, as part of a team or leading a team of fellow developers. Throughout my 5 years of development experience, I worked everywhere from startups to big companies, building products from the ground up or implementing new features. Also relevant to my set of skills is that - previously to becoming a developer - I worked as product manager for some of the biggest tech companies in the world, which still helps me to have a more holistic view of the whole work that goes into making a successful product. My go-to technologies are React and Node.js, and I have completed a wide range of projects using them. Those are not the only two libraries/frameworks I'm familiar with though, and I'm always happy to discuss my client's needs and find the best solutions for them. I consider myself creative and hardworking, as my stats show. If you liked my profile so far, drop me a message and we'll discuss how I can be useful to your project.

    I am a Full-Stack developer, primarily focused on backend technologies such as Node/NestJS, MongoDB, Nginx, and Linux servers. For the frontend, I excel at Vue, Nuxt, and Tailwind CSS. Additionally, I am a true believer in Karma, which means “what you do is what you get as a result.” Therefore, I am here, trying not to commit a sin by just coding.

    I am a Computer Science Bachelor and have almost 12 years of work experience in developing Backend-frontend and system engineering. I am versatile and thus, have a very keen interest in cutting-edge technologies changing the world as we know it today. I acquire exceptional knowledge about CS fundamentals like Data Structures, Algorithms, Object-Oriented Programming which form the basis of everything, and personally believe that a candidate's "skills" should be language agnostic and easily transferrable from one language to another, thus making me stand out from a pool of normalized candidates. This ability and mindset made it easy for me to program in various languages like Python, JavaScript, Java, Typescript, etc even though I was working in system engineering before. Another unique thing about me is that I can easily adapt and work on the frontend, backend, full-stack as well as the DevOps team given my ability to learn things quickly and apply them as and when needed. Along with this, I also have got a touch of data science in me thus resulting in a well-rounded software engineering enthusiast. So now as I look forward to entering an industrial setting as a Software Engineer, I know that there's yet more to learn, yet more to build, and yet more to solve! Here's a brief list of skills I possess: ✅ Languages: C/C++, Java, PHP, Python, NodeJS, JavaScript, Typescript, SQL. ✅ Frameworks/Lib: ⭐ HTML, CSS, Bootstrap, Semantic-UI ⭐ ReactJS/NextJS, Chakra UI, Tailwind CSS, Material UI, Ant Design, Redux ⭐ Node.js, Express.js ⭐ Python, Django ⭐ MongoDB, Mongoose, MySQL, PostgreSQL, TypeORM, Sequalize ⭐ Vue, Nuxt, Bootstrap-Vue ⭐ GraphQL, RESTful, Graphene, URQL, Tanstack Query/Table, DND-kit ✅ Hands-on: Algorithms, Object-Oriented Programming, Test Driven Development, Software Development, Model-view-controller, Web Scraping, Deployment, CI/CD. ✅Cloud Computing Services: ⭐GCP: Cloud Function, Kubernetes Engine ⭐AWS: Lambda, DynamoDB, Cognito, Cloud Front, Cloud Formation, RDS, Route 53 ✅ DevOps ⭐ Docker, Kubernetes, CI/CD Thank you!
