Freelance

During my freelance period, I built SaaS applications using Node.js + MongoDB + Redis, optimized with caching and rate limiting to ensure high performance and reliability.

I deployed containerized microservices to AWS (EC2, S3, Lambda) using Terraform and Docker, demonstrating expertise in cloud infrastructure and DevOps practices.

I added observability using Prometheus and alerting rules, ensuring that systems could be monitored effectively and issues could be detected early.

I improved performance with SQL indexing and query caching for multi-tenant workloads, optimizing database operations for better scalability.

This freelance experience allowed me to work on diverse projects and develop a strong foundation in modern backend development practices.
