What I'm looking for

I am looking for a dynamic work environment that fosters growth, innovation, and collaboration, where I can contribute to impactful projects and further develop my skills.

I'm a dedicated Backend Developer with a strong focus on Node.js, MongoDB, and API development. Currently, I work at Deloitte, where I design and implement scalable backend architectures that enhance application performance and user experience. My expertise in JWT authentication, caching mechanisms, and microservices allows me to create efficient and secure applications.

Throughout my career, I've successfully reduced response times by implementing Redis caching and optimized API performance through effective data modeling and pagination strategies. My experience extends to logging and monitoring solutions using tools like Grafana and Winston, which have significantly improved observability and debugging processes. I am passionate about leveraging technology to solve complex problems and continuously seek opportunities to enhance my skills in backend development.
