    With over 12 years of experience in software engineering, I've had the privilege of witnessing and contributing to the evolution of web technologies. Starting my journey as a front-end developer, I soon ventured into back-end development, mastering PHP, and exploring its capabilities. However, it was with Node.js that I truly found my passion. Joining HelloCrowd, I spearheaded a transformative project, migrating the entire API from PHP (Laravel Framework) to Node.js and transitioning from MySQL to Firebase, revolutionizing our backend infrastructure. Since then, I've had the privilege of architecting and building several significant products. Leveraging a tech stack that includes Node.js, Angular, Firebase, MongoDB, and the serverless framework, I've been able to craft robust, scalable solutions that stand at the forefront of modern development. Driven by an insatiable curiosity and a desire to stay at the forefront of technological advancements, I have embarked on an exhilarating journey to master a new frontier – AI Bots development (Open AI, Gemini, Claude, etc.)
