What I'm looking for

I seek senior full-stack or cloud-native engineering roles where I can design scalable systems, lead architecture, and optimize performance while working in collaborative, growth-focused teams.

I am a Senior Software Engineer with 10+ years building scalable web and mobile applications, microservices, and cloud-native architectures using modern JavaScript frameworks and strong TypeScript and Python skills.

I have led architecture and development of e-commerce SaaS platforms, microservices with NestJS, serverless deployments, and headless CMS integrations, delivering measurable improvements like 60% faster API responses and 35% higher user engagement.

I prioritize test coverage, performance optimization, and cost-efficient infrastructure using tools such as Terraform, Docker, Kubernetes, Vercel, and AWS, and I enjoy delivering full-stack solutions from React/Next.js front ends to resilient backend services.
