What I'm looking for

Seeking a challenging role in a collaborative environment that values technical excellence and innovation, offering opportunities for professional growth and impactful contributions.

As a Senior Software Engineer with over 12 years of experience, I specialize in designing and developing scalable, high-performance full-stack web applications. My expertise lies in the MERN stack, Ruby on Rails, Python, and React, with a strong focus on both backend and frontend development. I am passionate about building RESTful APIs, integrating third-party services, and optimizing performance to enhance user experience.

Throughout my career, I have led the development of several impactful projects, including a subscription management platform for over a million users and a real-time order tracking dashboard that improved customer engagement by 25%. I have successfully migrated systems to microservices architecture, increasing scalability by 60%, and have developed secure authentication mechanisms using JWT and Passport.js.

I am committed to delivering robust solutions, maintaining clean code, and collaborating across teams to meet business objectives. My experience includes working with companies like Groupon, PropertyNest, McAfee, Chime, and Amazon, where I have consistently improved application performance, reduced server load, and implemented best practices in Agile environments.
