What I'm looking for

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

I am a Senior Full Stack Engineer with over 10 years of experience in building enterprise software across various industries, including finance, healthcare, and logistics. My strong backend skills encompass Java (Spring Boot), Go, C#, and microservices architecture, complemented by solid experience in cloud deployments on AWS and Kubernetes. I am equally confident on the frontend, having hands-on experience with React, Angular, Vue.js, and Tailwind CSS to create responsive, accessible, and data-driven user interfaces.

Recently, I have focused on integrating AI and machine learning into my projects, utilizing tools like OpenAI API, LangChain, and FastAPI to deliver intelligent automation and enhance user experiences. My career has been marked by significant achievements, such as developing and deploying over 20 microservices and embedding AI capabilities into internal workflows, which have streamlined processes and improved efficiency.
