DevOps Engineer (CKAD) | Building scalable cloud infra on AWS | CI/CD pipelines @ Jenkins & Kubernetes

About

I’m a backend engineer turned DevOps-focused engineer who specializes in building scalable, cloud-native systems and the infrastructure that powers them. With a strong foundation in Node.js, TypeScript, Fastify, and Express, I design high-performance microservices and the automated, containerized environments that allow them to scale reliably in production. Over the years, I’ve worked extensively on distributed backend systems, database optimization, and asynchronous job processing, while also taking ownership of DevOps automation, CI/CD pipelines, and cloud infrastructure. I enjoy bridging the gap between clean application code and resilient, cost-efficient deployments. 🔧 What I Do Best: Backend Architecture & Microservices—Designing modular, scalable APIs and leading transitions from monolithic systems to microservices. Database Engineering – Modeling, tuning, and optimizing MongoDB and Redis for high availability, performance, and heavy workloads. DevOps & Cloud Infrastructure – Dockerizing applications, orchestrating services with Kubernetes, deploying on AWS (EC2, S3, Lambda), and automating CI/CD pipelines. Performance & Reliability Engineering – Profiling and refactoring systems to reduce latency, improve throughput, and achieve 99.9% uptime. Asynchronous & Background Processing – Building reliable queue-based workers and background task systems for large-scale workloads. Cost Optimization—Strategically managing cloud resources to reduce infrastructure costs while maintaining performance and reliability. 🚀 How I Work: I believe backend systems should be fast, scalable, resilient, and easy to operate. Whether modernizing legacy platforms, building new microservices, or improving deployment automation, I bring a strong sense of ownership, a systems-thinking mindset, and a focus on long-term maintainability. I thrive on solving complex distributed system challenges and enabling teams to ship faster with confidence.
