What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my skills in AI and full-stack development to create impactful solutions.

I am a Senior Full Stack Engineer with over 8 years of experience in designing scalable web applications and integrating AI and automation tools. My journey has taken me through diverse industries, where I have successfully led development teams and delivered business-critical solutions. I specialize in JavaScript frameworks, cloud platforms like AWS and GCP, and AI-powered workflow automation using tools such as OpenAI and Make.com.

Throughout my career, I have designed and deployed over 30 microservices, built robust chatbots, and migrated numerous automation flows to enhance operational efficiency. My ability to optimize system performance has been proven through various projects, including real-time dashboards and automated deployment pipelines. I take pride in mentoring junior developers and fostering a culture of clean architecture and AI implementation within my teams.
