    I am an advocate of clean coding, my favorite philosophy is Boy Scout rule "Always leave the Code cleaner than you found it". I like to deep dive into computer science concepts. I am not the type of programmer who is contented to just copy-paste code from the internet. I prefer to analyze code to understand why it works the way it does. I believe in the saying, "Low-level programming is good for the programmer's soul". During free time, I like to spend time contributing to opensource, I already contributed to opensource projects like Jhipster Generator, Mongock and Bitnami Redis. Skills and Technologies: • Languages: Proficient in Java, Node.js, Angular, Groovy, and Kotlin. Always updated with the latest trends and best practices. • Clean Architecture: A strong advocate of clean and efficient design, ensuring each project's robustness and scalability. • Front-End Development: Expertise in Angular, Vue.js, Nuxt, Tailwind, Bootstrap, crafting responsive and intuitive user interfaces. • Back-End Development: Skilled in Java, Node.js, and Groovy to develop server-side applications that are as resilient as they are expandable. • Cloud Computing: A solid track record with Amazon Web Services (AWS), designing and implementing scalable cloud solutions.

    I was trained classically, writing C and C++ code for Wall Street trading powerhouses like Goldman Sachs and Lehman Brothers. Running on advanced Unix systems, these lightning fast applications pioneered the field of today’s realtime global Fintech. As the Internet spawned open source platforms like Linux, MySQL, NodeJS, and AWS Cloud API’s, my skillset evolved into a full stack portfolio, where I built powerful back-end server software and the front-end web portals to deliver large, complex datasets via intuitive web portals. The maturing of JavaScript as the main language of the web, both on the front and back ends, has validated my decision to adopt NodeJS as my main coding platform in 2011. Today, JavaScript forms the glue of most of my applications, running on Node on the server, and in the browser up front. After moving to the West Coast in 2016, and spending time in Silicon Valley, I ventured away from financial systems to innovative applications like Blockchain Protocol coding and Video Streaming/Ffmpeg. I also coded network traffic optimization software down to the fundamental layers of the TCP/IP stack. All these big data applications naturally led me into the design and coding of custom algorithms. Whether compressing/chunking a video stream to play on a low powered mobile device, or parsing network packets for suspicious traffic, the ability to code an algorithm in plain C can make the difference between a successful production deployment, and non-performant code that never leaves the github repo. From my early career, I have made Database structure the centerpiece of my application design. Again, classical training in Dr. E. F. Codd’s model of Relational Databases has always informed my philosophy of how to structure an application’s data repository. With web-scale data, this field has grown to NoSQL and Graph databases. Now, huge datasets underpin the training of AI/ML models. I have kept my skills updated on these data technologies, and I combine the relevant elements of each to define the most appropriate data repository for my software.

    I love two things: coding, and design. Anything that involves these two words is of interest to me, which means I've always been intrigued to explore any fields that revolve around them, including web development, UI/UX design and prototyping, brand identity, photography, video editing, some system programming, some cybersecurity, and a little bit of everything. But as they say, “A jack of all trades is a master of none”, so right now, I am focusing on web development. The reason why I choose to undertake this career lies in its great correlation to design, in which I have had quite a few years of experience. Undoubtedly, a product's UI is vitally important to the overall user experience, because no matter how great and complex the backend infrastructure is, a poorly designed frontend will often create an obstacle between the user and the usability of the product, which makes all the backend work go down the drain. In that regard, I believe that it's equally important to ensure good communication between the designer and the frontend developer and that the greatest way to achieve that is to ensure that they share a common understanding of design concepts. Therefore, as someone who is both a designer and a developer, I believe that my skills and efforts should be channeled into filling this gap!
