What I'm looking for

I seek a senior technical role where I can lead development, optimize systems, and implement cloud-native CI/CD practices while growing with a collaborative team.

I am a senior full-stack developer with over five years of experience building scalable web platforms, leading teams, and implementing CI/CD and cloud deployments. I have driven measurable improvements — for example, improving platform performance by 50% and reducing costs by 40% through targeted frontend and backend optimizations, and cutting deployment time by over 80% through CI/CD practices.

I specialize in Node.js, NestJS, React, Angular and cloud services (AWS, Azure, Google Cloud), and I focus on integrating systems, message queues, and microservices to meet business goals. I continuously learn new technologies, work effectively in teams, and take ownership as a technical lead to deliver reliable, efficient solutions.
