What I'm looking for

I am looking for a challenging role that fosters innovation, collaboration, and growth opportunities in a dynamic tech environment.

I am a Senior Software Engineer with over 9 years of extensive experience in all phases of the Software Development Life Cycle (SDLC). My expertise spans requirements analysis, application design, development, integration, maintenance, installation, implementation, and testing of various client, server, and web applications. I have a strong background in both frontend and backend development, utilizing frameworks such as React, Angular, and Vue, as well as backend technologies like Node.js and Django.

Throughout my career, I have successfully developed and deployed high-performance applications, including a dynamic dashboard at Apple and the world's first blockchain-based web browser at MASQ. My commitment to quality and performance is evident in my ability to improve API response times significantly and enhance user engagement through innovative features. I thrive in collaborative environments and prioritize clear communication with team members and stakeholders to ensure project success.
