Backend Developer
Category : Web development
A backend-focused software engineer with over six and a half years of experience building scalable, reliable systems for product-driven applications. My core expertise is in Node.js and Python, where I’ve designed and developed RESTful APIs, microservices, and serverless architectures used in production at scale. I have strong experience with relational and NoSQL databases such as PostgreSQL, MySQL, MongoDB, DynamoDB, and Redis, with a focus on performance, data modeling, and system reliability.
I’ve worked extensively with cloud platforms like AWS and Google Cloud, contributing to cloud-native designs, CI/CD pipelines, monitoring, and infrastructure automation, as well as participating in large-scale cloud migrations.
I enjoy working in fast-paced environments where backend decisions directly impact users and business outcomes. I’m adaptable, proactive, and quick to learn new technologies to deliver effective, scalable solutions
