What I'm looking for

I am looking for a role that fosters innovation, collaboration, and continuous learning, where I can contribute to impactful projects and grow my technical expertise.

As a Senior Full Stack Developer at Snapsheet Inc, I have honed my skills in developing and maintaining scalable web applications using modern technologies like React, Next.js, Node.js, and .NET. My focus on performance optimization has led to a 29.7% enhancement across devices, while my integration of third-party services has significantly reduced operational overhead by 50.3%. I take pride in designing secure, modular RESTful APIs and managing CI/CD pipelines that ensure high availability and reliability.

Previously, I contributed to building a phishing incident response platform at Offshore Development Center, automating workflows that improved incident turnaround times. My experience spans various roles, including Full Stack Developer at Codup, where I developed customer-facing applications that enhanced user experience and streamlined complex workflows. I thrive in collaborative environments, working closely with cross-functional teams to align technical solutions with business goals.
