What I'm looking for

I am looking for opportunities that foster innovation, collaboration, and career growth.

I am a result-driven and solution-oriented Senior Full-Stack Software Engineer with a strong passion for tackling complex challenges. With extensive experience in developing scalable applications, I have led teams to create innovative solutions, including an AI-driven healthcare platform that enhances diagnostics and prescriptions through real-time ECG data analysis.

Throughout my career, I have successfully migrated legacy systems to microservices architectures, designed robust APIs, and implemented secure authentication mechanisms. My expertise spans across various technologies, including Node.js, Python, React, and cloud services like AWS and GCP. I thrive in fast-paced, agile environments and enjoy mentoring junior developers to foster team growth and efficiency.
