What I'm looking for

I’m looking for a team building reliable, scalable cloud-native systems. I want to own backend and DevOps work—using AWS, Infrastructure as Code, and CI/CD—to improve performance, security, and cost efficiency while shipping with quality.

I’m a results-driven Backend and DevOps Engineer with 4+ years of experience designing, deploying, and maintaining cloud-native applications on AWS. I’ve scaled systems from 60 to 1,000+ concurrent users while reducing costs by 40% through infrastructure optimization.

In my roles, I focus on Infrastructure as Code and automation to make releases dependable—using AWS CDK, GitHub Actions, and containerization with Docker. I’ve modernized legacy services into unified stacks (e.g., NestJS + Prisma) and tightened reliability with performance tuning, caching, and database optimization.

I also bring a security-and-performance mindset: I’ve built automated security countermeasures, improved query latency (e.g., 85% faster), and implemented resilient architectures like microservices, event-driven processing, and real-time monitoring. I’m passionate about building reliable, scalable systems that drive business value.
