I’m a Full Stack Engineer with 4+ years of experience building scalable, high-performance cloud‑native SaaS applications using React, TypeScript, NestJS, Go, and AWS services.¹
I focus on system design, performance optimization, and cost‑efficient architectures for high‑traffic products.

• Designed and shipped production systems for global SaaS platforms.
• Improved API performance through query optimization, caching, and better data models.
• Reduced AWS infrastructure costs and led microservices and event‑driven backend initiatives.

• Scalable backends & APIs – NestJS/Node.js and Go services on AWS (Lambda, EC2, S3, DynamoDB, SQS, SNS).
• System design & distributed systems – microservices, event‑driven architecture, high‑availability designs.
• Performance & cost optimization – query tuning, caching, infra right‑sizing, and observability.
• Web & mobile frontends – React, Next.js, and React Native for SaaS dashboards and cross‑platform apps.

• 🚀 (In Progress) Flash Sale / Ticketing Backend – high‑concurrency backend using Go/NestJS, Redis, and Postgres to handle thousands of users buying limited tickets without overselling.
• 🧮 Salary Calculator (Clean Architecture + TDD) – Python/TypeScript service with 4‑layer clean architecture and full test coverage for salary and metrics calculation.
• 📊 SaaS Analytics Dashboard – React + Next.js dashboard powered by microservices and GraphQL for real‑time business metrics.
• 📱 React Native App – production mobile app with real‑time communication and optimized MySQL queries for better performance.

Each project is documented with a clear problem statement, architecture overview, and setup instructions.
