    I am a highly motivated and proactive professional with a passion for tackling complex problems and continuously expanding my knowledge. My strengths lie in my proficiency in Java, Python, JavaScript, NodeJS, Angular and SQL. I am detail-oriented, a problem solver, and possess strong analytical skills. I am a quick learner, capable of adapting to new technologies and environments. In terms of personal projects, I have developed a Java application called Paint, which allows users to draw, erase, select colors, and work with predefined shapes. Additionally, I worked on a Python project involving sales forecasting using Walmart sales data. Through the utilization of Extra Trees and Random Forest regressors, I achieved a low mean squared error, demonstrating my ability to effectively apply machine learning techniques. During my professional experience, I had the opportunity to work on an ASP.NET framework application, where I played a key role in developing functionalities for a digital lending platform. I successfully refactored existing code, optimizing performance and efficiency. Additionally, I led the development of an integration service that facilitated seamless communication between our backend and the client's core system. Moreover, I took charge of the product deployment in the client's environment and contributed to a data migration project on .NET Core, showcasing my expertise in system implementation and integration. In my previous role, I worked on property management and booking software, where I demonstrated my problem-solving abilities. I resolved three challenging bugs, including a critical race condition that resulted in skipped notifications to clients. Furthermore, I made significant contributions to our chatbot system, implementing error-catching codes and enhancing the overall user experience. By implementing strategies to catch and report errors and unallowed program flows, using tools such as assertion and Slack reporting, I ensured a robust and reliable application. Additionally, I successfully integrated various services, including Yardi, Zapier, Outlook Calendar, and Gmail Calendar. Furthermore, I managed AWS instances, overseeing the management of EC2 and RDS, and upgraded our Node 10 application to Node 14 LTS, highlighting my ability to adapt to evolving technologies. Currently, I am working with as part of the LeaseGuard development team under CitadelUS, I’ve led and contributed to building scalable solutions that streamline property insurance workflows for property managers. I developed a robust platform integrated with major property management and CRM systems, accelerating client onboarding and simplifying long-term maintenance. I have seamlessly integrated with Yardi, RealPage, Entrata, RentManager, Zoho CRM, and HazardHub. By automating core processes—such as opt-in/out workflows and data synchronization—I reduced manual effort by 80% and significantly improved reporting accuracy. I also implemented an automated reporting system that saves account managers over 40 hours per month, and designed a modern, auto-fill verification form that increased user submission rates by 40% while standardizing CRM data entry. I am thrilled to leverage my skills and knowledge to take on new and challenging projects. I am eager to contribute my problem-solving abilities and make a positive impact, continuously pushing the boundaries of my expertise and delivering exceptional results.
