What I'm looking for

I am looking for a role that values collaboration and innovation, where I can leverage my full-stack expertise to drive impactful projects and contribute to a dynamic team culture.

I am a results-oriented Senior Full-Stack Engineer with over 7 years of experience in architecting and delivering scalable, high-performance web applications across various sectors, including hospitality, healthcare, and HR tech. My expertise lies in building robust microservices, RESTful and GraphQL APIs, and secure authentication systems using technologies such as React.js, Next.js, and Node.js. I thrive in Agile environments, collaborating effectively with cross-functional teams to optimize system performance and deliver maintainable solutions that align with business goals.

Throughout my career, I have successfully led the development of custom digital platforms, enhancing user experiences and improving accessibility scores significantly. My role at Airteam involved architecting a healthcare provider's digital platform, where I implemented modular backend services and enhanced CI/CD pipelines, resulting in a 50% reduction in manual QA time. I am passionate about mentoring peers and fostering a collaborative environment, ensuring that both frontend and backend architectures are aligned for optimal performance.
