Welcome to My Blog

Hello! I’m Sokos Lee, and I’m excited to launch this technical blog where I’ll share my experiences, insights, and lessons learned from over a decade of building e-commerce systems and five years of developing AI/ML applications.

What This Blog Is About

This blog sits at the intersection of three domains I’m passionate about:

🏪 E-commerce System Architecture

E-commerce is more than just online shopping—it’s about building resilient, scalable systems that can handle millions of transactions while providing seamless user experiences. I’ll share insights on:

  • High-concurrency architecture design - How to build systems that scale to handle Black Friday-level traffic
  • Payment integration patterns - Best practices for integrating with Stripe, PayPal, and global payment providers
  • Microservices design - Breaking down monolithic e-commerce systems into manageable, scalable services
  • Cross-border commerce - Tackling the unique challenges of international e-commerce

🤖 AI/ML Engineering

Artificial Intelligence is transforming how we build software. From large language models to computer vision, I’ll cover:

  • LLM application development - Practical guides for building with GPT, Claude, and other frontier models
  • RAG systems - Retrieval-Augmented Generation for building knowledge-based AI applications
  • Recommendation algorithms - From collaborative filtering to deep learning-based recommendations
  • AI infrastructure - Vector databases, embeddings, and the tools that power modern AI applications

⚡ E-commerce + AI Integration

The real magic happens when we combine these two domains. I’ll explore:

  • AI-powered customer service - Building intelligent chatbots that actually help customers
  • Intelligent product recommendations - Using ML to increase conversion rates and customer satisfaction
  • Automated content generation - Leveraging LLMs to scale product descriptions and marketing copy
  • Smart search and discovery - Semantic search and visual search using vector databases
  • Fraud detection - Machine learning for security and risk management

What to Expect

I believe in practical, actionable content. Each post will include:

  • Real-world examples from production systems
  • Code samples you can actually use
  • Architecture diagrams and technical deep-dives
  • Performance considerations and optimization tips
  • Lessons learned from both successes and failures

Topics Coming Soon

Here’s a preview of upcoming articles:

  1. Building a High-Performance E-commerce API with Node.js - Lessons from handling 10K+ requests per second
  2. LLM-Powered Customer Service: From Prototype to Production - A complete guide to building AI chatbots for e-commerce
  3. Recommendation Systems 101 - Building your first collaborative filtering engine
  4. RAG for E-commerce: Building a Product Knowledge Base - Using vector databases for semantic product search
  5. Payment Integration Best Practices - Everything you need to know about Stripe, webhooks, and reconciliation

Let’s Connect

I’m always excited to connect with fellow engineers, especially those working in e-commerce, AI/ML, or at the intersection of both. You can find me on:
