What I'm looking for

I am looking for a role that offers opportunities for growth, collaboration, and innovative projects in a dynamic environment.

I am a dedicated Full Stack Developer with over six years of experience in creating robust web applications. My expertise spans both frontend and backend technologies, including Angular, React.js, ASP.NET Core, and FastAPI. I have a strong background in unit and integration testing, CI/CD pipelines, and deployment, which ensures high-quality deliverables. My problem-solving skills and collaborative approach have consistently contributed to successful project outcomes.

In my recent role as a Senior Full Stack Engineer at PCX, I developed and maintained the company website, integrated RESTful APIs, and utilized advanced tools like HubSpot and Kafka to enhance user experience and system scalability. My previous experiences at Linkt and Jicoo, Inc. have further honed my skills in designing comprehensive solutions and implementing microservices architectures. I am passionate about leveraging technology to solve complex problems and improve user engagement.
