What I'm looking for

I am looking for a challenging role that fosters innovation and allows me to leverage my skills in full stack development and IoT solutions, while also providing opportunities for professional growth and collaboration in a dynamic team environment.

I am a Full Stack Developer with over 5 years of experience in building web applications and microservices. My expertise lies in TypeScript, JavaScript, React.js, and Node.js, complemented by a strong foundation in database design and DevOps practices. I have a proven track record of developing responsive user interfaces and robust backend services, utilizing both SQL and time-series databases.

In my current role as a Senior Engineer at Emerson Innovation Center, I have developed multiple backend services using microservice architecture, significantly improving data integration and real-time communication. My work has led to a 50% reduction in load times for frontend UIs and the creation of optimized data pipelines for historical sensor data. I am passionate about leveraging technology to solve complex problems and enhance operational efficiency.
