My Development Workflow 2026-Q1 Edition
A tour of my agentic development workflow in five phases: brainstorm, design, plan, code, and review plus improve. Covers Cursor and Claude Code with Superpowers skills, AGENTS.md files, parallel worktrees, the MCP servers I rely on daily, and what a good day of mostly-autonomous software delivery actually looks like.

Authorization in a Shifting Maze
Why authorization tooling is straining in the AI era: OPA policies that grow slow and unexplainable past a few dozen rules, ReBAC systems like SpiceDB that trade flexibility for a queryable graph, and AI agents that sit inside the perimeter with no gateway in the loop, pushing us toward dynamic, function-level, context-aware authorization through protocols like MCP and A2A.

Next-Gen Languages, Compilers, and IRs for AI
How MLIR, TVM, and SPIR-V are replacing hand-tuned CUDA kernels in the AI stack: MLIR's reusable compiler dialects, TVM's auto-tuned kernel search that beat handwritten code on Apple M1 at launch, and SPIR-V's vendor-neutral GPU bytecode, and how the three cooperate so one model can run fast on any accelerator, from PyTorch 2.0 to WebGPU.

O Dia em que Construí uma IA para Prever Preços de Personagens de Tibia
A história completa do TCAQS, um modelo XGBoost que prevê preços de leilões de personagens de Tibia: raspando 650.000 páginas de leilão a três requisições por segundo, convertendo tudo em SQLite, e três rodadas de engenharia de features e limpeza de dados que levaram o modelo de um baseline de 0,89 até 0,935 de R² em teste, com demo ao vivo no Hugging Face Spaces.

The Day I Built an AI to Predict Tibia Character Prices
The full story of TCAQS, an XGBoost model that predicts Tibia character auction prices: scraping 650,000 auction pages at three requests per second, parsing them into SQLite, and three rounds of feature engineering and label cleaning that took the model from a 0.89 baseline to 0.935 test R², plus a live demo on Hugging Face Spaces.

OO Interfaces, Types & Contracts — Why They Still Matter in 2025
Why object-oriented interfaces, static types, and design-by-contract still pay off in 2025: fewer undefined-method surprises, documentation that can't rot, cleaner module boundaries, and why explicit contracts make AI coding agents dramatically more reliable. Plus the cost spectrum from C to Rust, and when minimal typing is the smarter trade.
