I’m a Backend Engineer with 2+ years of experience building scalable, high-performance backend systems using Node.js, NestJS, Python, and cloud-native technologies on AWS. I focus on event-driven architectures, RESTful APIs, and asynchronous workflows using queues and distributed systems.

In my current role, I architected and deployed a scalable backend system from scratch serving 40,000+ users within the first month. I built a cloud-native infrastructure on AWS using S3, DynamoDB, SQS, SNS, and Transcribe to automate video transcription, notification processing, and asynchronous communication workflows.

I also care deeply about production reliability: I implemented robust authentication, secure file management, and scalable API design that holds up under high traffic. Across roles and projects, I integrate third-party services (payments, email systems, AI-based solutions) and deliver clean, maintainable systems with real-world problem solving.
