A full walkthrough of every quality dimension that separates a working MCP server from a well-built one — tool descriptions, dot notation naming, annotations, caching, smithery.yaml, and the skill that automates all of it.

A head-to-head ablation of 7 open-source PDF parsers on customer complaint forms — scanned, handwritten, AcroForm, and degraded fax. How each parser internally detects words, where they break, and which to pick for production.

How I built a wine price comparison tool for Singapore. Amex Platinum gives you S$200 back on wine, but are the base prices actually competitive? I answered that with Selenium scraping, bundle-aware comparisons, Brave-assisted Vivino resolution, and a guarded daily refresh pipeline.

How I built an AI-powered job aggregator and resume coaching platform for the Singapore job market. Nightly crawls from MyCareersFuture and Careers@Gov, a 7-stage resume tailoring pipeline, and 5 validation gates to prevent AI hallucination. Born from a real job search frustration and revived by a friend's conversation about resume building.

Markets have moods. A Hidden Markov Model reads the volatility regime (calm, normal, or stormy) so you can trade with the weather, not against it. Interactive walkthrough with live visualizations.

Interactive walkthrough of Direct Preference Optimization - how to align LLMs with human preferences using just a classification loss. No reward model, no RL, no PPO. Play with the DPO loss calculator and watch training step by step.

19 engineers, 19 A100 GPUs, two hours of Locust fire. I tuned 40+ vLLM configs and scraped peer metrics. Then someone with a 30-line cache proxy beat all of us.

Prefill vs decode. Why memory bandwidth matters more than FLOPS. VRAM budget math. Quantization methods (GPTQ, AWQ, FP8). Batching strategies. The theory behind every LLM serving decision.

Interactive walkthrough of the WMSS paper — from SFT saturation to logit mixing and gradient amplification. Play with lambda sliders, watch training curves, and understand how weak agents make strong agents stronger.

MediaPipe face mesh, rembg segmentation, 25+ compliance checks, and country-specific rules for 6 countries. Here's how Photo ID Studio decides if your face is passport-worthy.

A deep dive into Trader Koo – from using a pre-trained YOLOv8 model to detect chart patterns, to solving the coordinate mapping problem, to running a five-layer detection ensemble every night.

Building LionWeather: tropical weather data from 2016 to 2024, LightGBM rainfall forecasting, SHAP explainability, animated radar, and a whole lot of lessons about Singapore weather.
