What I'm looking for

I am looking for a back-end engineer role where I can tackle complex challenges and contribute to innovative projects.

I'm a back-end software engineer with four years of experience specializing in Java and Python. My expertise lies in microservice architecture and API development, where I have successfully led engineering initiatives that contributed over $6 million in annual revenue. I thrive on solving complex technical challenges and mentoring junior engineers to foster their growth.

At Broadcom, I developed high-volume order management microservices and spearheaded initiatives that significantly improved efficiency and reduced processing times. My experience also includes collaborating on machine learning projects, where I utilized Python and TensorFlow to create data pipelines and models that drove strategic trading decisions. I am passionate about leveraging my skills to create impactful solutions in a dynamic work environment.
