ServerlessFlow - AWS Lambda Alternative

2024 • Open Source Serverless Platform

⚡

Open-source serverless function platform

An open-source alternative to AWS Lambda built using Apache OpenWhisk, Docker, and MERN stack. This platform allows developers to deploy serverless functions with custom runtimes, scale automatically based on demand, and pay only for actual execution time.

Key Capabilities

  • Function-as-a-Service: Deploy Node.js, Python, or Go functions without managing servers
  • Cold Start Optimization: Implemented warm containers to reduce startup time by 70%
  • Auto-scaling: Automatically scales based on request volume
  • Custom Runtimes: Support for any programming language via Docker containers
  • Monitoring Dashboard: Real-time metrics, logs, and performance analytics
  • API Gateway Integration: Built-in API gateway for routing and authentication

My Development Philosophy

I believe in learning by building real systems. Each project starts with understanding the problem deeply, then designing a solution that's both practical and scalable. I focus on clean architecture, proper documentation, and writing code that's easy to maintain.

🎯

Problem-First Approach

Understand the problem thoroughly before writing any code

📚

Documentation as Code

Write documentation alongside code, not as an afterthought

🧪

Test Early & Often

Write tests during development, not at the end

🚀

Ship & Iterate

Get working software out quickly, then improve based on feedback
