What I'm looking for

I seek a challenging role in a dynamic IT environment that fosters growth.

I am a dedicated System Analyst and Full Stack Developer with over a decade of experience in delivering innovative IT solutions. My journey began in 2006, and since then, I have honed my skills in various programming environments, including C#, .NET Core, and Angular. I have successfully led and contributed to numerous projects, such as the Teaching Performance Evaluation and Monitoring System, which streamlined faculty evaluations through data visualization and user-friendly interfaces.

Throughout my career, I have demonstrated a strong ability to collaborate with cross-functional teams, ensuring that business processes are effectively addressed through technology. My role as a Lead Developer at MFA Accounting Services allowed me to spearhead the development of a comprehensive booking service application, enhancing operational efficiency for healthcare professionals. I am passionate about leveraging my technical expertise to create impactful solutions that drive organizational success.
