• Vectorization in Python — NumPy vs Pandas vs Polars vs Numba

  Posted on:April 14, 2025 |  at 10:00 AM

  Systematic benchmarks comparing four vectorization approaches across different dataset sizes and operation types. When to use NumPy directly, when Polars wins, and when Numba's JIT compilation is the only answer.

• Building a Real-Time DEX Price Monitor with Node.js and WebSockets

  Posted on:March 17, 2025 |  at 10:00 AM

  Step-by-step guide to building a real-time DEX price monitor that listens to Uniswap V2/V3 swap events via WebSocket, decodes transaction logs, and broadcasts live price updates to connected clients. Complete TypeScript implementation with reconnection logic.

• Compound Interest — A Software Engineer's Mathematical Guide (Interactive)

  Posted on:February 24, 2025 |  at 10:00 AM

  Compound interest from first principles: discrete vs continuous compounding, the Fisher equation for real returns, the Rule of 72, and why the difference between annual and monthly compounding matters more than most people think. All interactive.

• Spec-Driven Development — The AI-Native Engineering Workflow I Use Daily

  Posted on:February 10, 2025 |  at 10:00 AM

  Spec-Driven Development is the workflow where you write a precise specification first, then use AI to generate and iterate on the implementation. It sounds like prompt engineering — it's actually a different way of thinking about software design.

• Gas Optimization in Solidity — Techniques That Saved Real ETH

  Posted on:January 13, 2025 |  at 10:00 AM

  Concrete Solidity gas optimization techniques with before/after gas measurements: storage layout packing, calldata vs memory, custom errors, unchecked arithmetic, and mapping vs array tradeoffs. Numbers from a real ERC-20 + staking contract optimization.

• Node.js Worker Threads — True Parallelism Without the Cluster Mess

  Posted on:December 9, 2024 |  at 10:00 AM

  Node.js Worker Threads enable true CPU parallelism in a single process. This post covers the communication model, SharedArrayBuffer for zero-copy data sharing, thread pool patterns, and benchmarks showing when Workers outperform cluster vs when they don't.
