I am a seasoned Full Stack Developer with over 9 years of experience in crafting robust and secure software solutions. I started with traditional languages like C# and Java and have since expanded into various languages like JavaScript, Ruby, and Python. Throughout my career, my primary focus has been on building highly secure platforms and maintaining codebases that are easily testable through unit testing. My extensive knowledge extends to both SQL and NoSQL databases, including Oracle, PostgreSQL, MySQL, MongoDB, and AWS DynamoDB. I have a deep understanding of database design and optimization, which enables me to create efficient and scalable data solutions. In recent years, I've immersed myself in blockchain technology and DeFi, staying at the forefront of this rapidly evolving field. I'm also a proficient user of AWS cloud services for deployment and continuous integration/continuous deployment (CI/CD) pipelines. I've worked with a wide array of AWS services, including but not limited to ECS, EKS, EC2, API Gateway, and Lambda, enabling seamless deployment and scaling of applications. My technology stack is versatile: Frontend: React Native, React.js(Next.js and Gatsby.js), Vue.js, Svelte, Angular and Blazor Backend: Java Spring Boot, TypeScript Node.js (Nest.js), PHP Laravel, Ruby on Rails, Go Architecture: Microservices, messaging with Kafka Database: Oracle, PostgreSQL, MongoDB, AWS DynamoDB, Redis DevOps: Docker, Kubernetes, AWS services I'm always eager to learn new technologies and deliver top-notch results. Let's work together to achieve your goals in software development!

Thanks to Luis -you did a great job sorting out my database issues and we are on track again thanks to your skills. If you are in need of a reliable freelancer well skilled Luis will get your problem sorted. We had issues with my codes and other complications from a past freelancer. Luis has rewritten these as required and now my Booking system is running great. Thanks and I will be in touch for my next job. [12 November, 2025] Luis did a great job for me fixing up my very messy database that had been sort of corrupted by other freelancers with a lower level of skill. I highly recommend Luis and if you need a top notch man I recommend Luis for any job. Very highly skilled.

Luis is a person to avoid like the plague. He's the kind of freelancer you never want to work with; he's uncommunicative, has a spiteful attitude, and doesn't follow directions. For me, it was a terrible experience and I wouldn't recommend it to anyone.

The technical specs were not entirely clear at the beginning, mainly because I only knew the functional specs. Due to Luis' willingness to succeed, I am happy :-) I really appreciate Luis' perseverance while making it work, so my big thanks to him!!

My project was complex and required troubleshooting javascript, mysql, php and media player implementation. He navigated through messy code, complex functionality for a custom made website while updating the existing media player. He quickly adapted to challenges and successfully delivered as promised. Great communication and offers great input on the project as he notices potential improvements. I consider him a great freelancer. I look forward to future projects!
