👋 Hello there, I'm Sai

🚀 Passionate Developer • 🧠 Learner • 🛠 Builder • 🔐 Security Enthusiast

I love working across the stack — from frontend frameworks like Angular, React, and Vue.js to resilient backend systems built with Node.js, Go, and cloud-native architectures. I have solid exposure to AWS, serverless patterns, automation, and designing systems that scale reliably under real-world workloads.

Alongside engineering, I’m deeply passionate about automation,web application security, building blockchains/decentralized systems, smart contracts, understanding how things break, hardening systems, and building safer software. I'm always experimenting with new ideas, building tools, and learning deeply by doing.


🚀 Currently

  • Exploring Modern Web Application Vulnerabilities
  • Exploring Modern web performance & HTTP protocols
  • Exploring Smart Contract Development for EVM
  • Building automated tooling & security scanners

⚡ Skills at a Glance

  • Strong in JavaScript / TypeScript with deep experience in Node.js
  • Build resilient backend systems — serverless, event-driven, microservices
  • Hands-on with AWS (Lambda, API Gateway, Dynamo/Mongo, IAM, S3, CloudFront, etc.)
  • Experience in Web App Security, pentesting, and supply-chain analysis
  • Skilled with Go, Python, Bash for tooling & automations
  • Build cross-platform mobile apps using Flutter/Dart with clean architecture & performant UI
  • Build automation, CI/CD(both web and mobile, mobile via fastlane), and developer tooling
  • Love building things for performance, debugging issues & exploring modern cloud architectures.
  • Building Decentralized Systems & Smart Contract Engineering — Good understanding of Blockchain principles, Ethereum, Solidity, EVM internals, contract security, and designing scalable, trust-minimized architectures.

I love working across the stack — from frontend frameworks like Angular, React, and Vue.js to resilient backend systems built with Node.js, Go, and cloud-native architectures. I have solid exposure to AWS, serverless patterns, automation, and designing systems that scale reliably under real-world workloads.

Alongside engineering, I’m deeply passionate about automation,web application security, building blockchains/decentralized systems, smart contracts, understanding how things break, hardening systems, and building safer software. I'm always experimenting with new ideas, building tools, and learning deeply by doing.


🚀 Currently

  • Exploring Modern Web Application Vulnerabilities
  • Exploring Modern web performance & HTTP protocols
  • Exploring Smart Contract Development for EVM
  • Building automated tooling & security scanners

⚡ Skills at a Glance

  • Strong in JavaScript / TypeScript with deep experience in Node.js
  • Build resilient backend systems — serverless, event-driven, microservices
  • Hands-on with AWS (Lambda, API Gateway, Dynamo/Mongo, IAM, S3, CloudFront, etc.)
  • Experience in Web App Security, pentesting, and supply-chain analysis
  • Skilled with Go, Python, Bash for tooling & automations
  • Build cross-platform mobile apps using Flutter/Dart with clean architecture & performant UI
  • Build automation, CI/CD(both web and mobile, mobile via fastlane), and developer tooling
  • Love building things for performance, debugging issues & exploring modern cloud architectures.
  • Building Decentralized Systems & Smart Contract Engineering — Good understanding of Blockchain principles, Ethereum, Solidity, EVM internals, contract security, and designing scalable, trust-minimized architectures.
