O que aprendi ao voltar ao pg e escrever SQL à mão.\",\n },\n tags: [\"Node.js\", \"PostgreSQL\", \"Backend\"],\n content: `\n## The problem with ORMs at scale\n\nI've used Sequelize, TypeORM, and Prisma across different projects. For simple CRUD apps they're great — you get type safety, migrations, and a nice API out of the box. But once your queries grow beyond a few joins, things start to fall apart.\n\nThe turning point for me was a reporting query at Dragonboat. It involved multiple CTEs, window functions, and conditional aggregations. The Prisma version was a wall of \\`$queryRaw\\` with TypeScript fighting me every step. The raw SQL version was clean, readable, and 3x faster.\n\n## What I switched to\n\nI moved to **[postgres](https://github.com/porsager/postgres)** (the \\`sql\\` package by porsager). It gives you tagged template literals with automatic parameterisation, so SQL injection is still handled correctly:\n\n\\`\\`\\`ts\nconst users = await sql\\`\n SELECT id, name, email\n FROM users\n WHERE active = true\n AND created_at > \\${since}\n ORDER BY created_at DESC\n LIMIT \\${limit}\n\\`;\n\\`\\`\\`\n\nNo magic. No hidden N+1 queries. No wondering what SQL your ORM is actually generating.\n\n## Migrations\n\nThe one thing ORMs genuinely do well is migrations. I replaced that with **[db-migrate](https://db-migrate.readthedocs.io/)** for structured migrations and a simple \\`schema.sql\\` file as source of truth. Not glamorous, but it works.\n\n## When I'd still use an ORM\n\n- Greenfield CRUD-heavy apps where speed of development matters more than performance\n- Teams where not everyone is comfortable with SQL\n- Simple one-table queries where the ORM adds zero friction\n\nFor anything else? Write the SQL. You'll thank yourself later.\n `,\n },\n {\n slug: \"valtown-scratchpad\",\n date: \"Feb 22, 2026\",\n readTime: { en: \"4 min read\", pt: \"4 min leitura\" },\n title: {\n en: \"Val.town is the scratchpad I always wanted\",\n pt: \"Val.town é o bloco de notas que sempre quis\",\n },\n excerpt: {\n en: \"Deploying a cron job used to take 20 minutes of boilerplate.

Uma visita rápida ao meu uso do Val.town.\",\n },\n tags: [\"Val.town\", \"TypeScript\", \"Automation\"],\n content: `\n## The old way\n\nBefore Val.town, deploying a simple cron job meant: create a repo, write a Dockerfile or serverless config, set up CI, configure environment variables, deploy to AWS Lambda or a VPS, set up CloudWatch or cron-job.org to trigger it... You get the idea.\n\nFor side projects and experiments, that overhead kills momentum.\n\n## Enter Val.town\n\nVal.town flips this completely. A cron job is just a TypeScript function:\n\n\\`\\`\\`ts\nexport default async function() {\n const res = await fetch(\"https://api.example.com/prices\");\n const data = await res.json();\n if (data.price > 50000) {\n await email({ subject: \"BTC above 50k!\", text: \\`Price: \\${data.price}\\` });\n }\n}\n\\`\\`\\`\n\nSet the schedule, hit save. It runs. That's it.\n\n## What I've built on it\n\n- **Crypto price alerts** — pings me when BTC or ETH move more than 5% in an hour\n- **Imóveis tracker** — scrapes Portuguese real estate listings for specific search criteria\n- **Football data pipeline** — ingests fbref match data, enriches with AI, exposes a REST API\n- **This portfolio** — served as an HTTP val\n\n## The catch\n\nVal.town has limits — execution time, storage, and egress. For production workloads, it's not a replacement for proper infrastructure. But for the 80% of side project needs? It's unbeatable.\n\nIf you haven't tried it, spend 10 minutes on [val.town](https://val.town).

O que funcionou, o que não funcionou, e se voltaria a fazê-lo.\",\n },\n tags: [\"React\", \"Frontend\", \"Performance\"],\n content: `\n## Context\n\nAt Dragonboat we have a large React codebase. Most of it is a classic SPA — client-side routing, Redux, REST API calls from the browser. Last year we started migrating our public-facing pages and some dashboard sections to React Server Components.\n\nHere's my honest take after 12 months.\n\n## What worked well\n\n**Data fetching is genuinely simpler.** Being able to \\`await\\` directly in a component, close to where the data is used, removes a lot of the boilerplate around loading states and effects:\n\n\\`\\`\\`tsx\nasync function RoadmapList({ teamId }: { teamId: string }) {\n const roadmaps = await db.roadmaps.findMany({ where: { teamId } });\n return

)}

;\n}\n\\`\\`\\`\n\n**Bundle size dropped.** Heavy dependencies (date libraries, markdown parsers, chart configs) that were previously shipped to the client are now server-only. Our initial JS bundle shrank by ~35%.\n\n**Waterfall requests are easier to reason about.** With client components you'd fire multiple \\`useEffect\\` fetches that cascade. RSC makes the data flow sequential and explicit.\n\n## What didn't work\n\n**The mental model is genuinely hard to teach.** The \"which components are server vs client\" question trips up everyone on the team. We've had bugs from accidentally importing server-only code into client components.\n\n**Interoperability with our existing state management is painful.** Redux and RSC don't mix naturally. We ended up with a hybrid approach that feels awkward.\n\n**Error boundaries and loading states feel more fragmented.** The Suspense + RSC combination works, but debugging a broken streaming boundary is not fun.\n\n## Would I do it again?\n\nYes — but only for the right parts of the app. RSC shines for read-heavy, data-driven pages. For interactive, stateful UIs, classic client components are still the right tool.\n\nThe migration isn't free, but the performance and DX wins on the right pages are real.\n `,\n },\n {\n slug: \"football-stats-pipeline\",\n date: \"Dec 5, 2025\",\n readTime: { en: \"10 min read\", pt: \"10 min leitura\" },\n title: {\n en: \"Building a real-time football stats pipeline with AI enrichment\",\n pt: \"Pipeline de estatísticas de futebol em tempo real com IA\",\n },\n excerpt: {\n en: \"How I wired fbref data → scheduled workers → GPT analysis → live API in a weekend, entirely on serverless infrastructure.\",\n pt: \"Como liguei dados do fbref → workers agendados → análise GPT → API em direto num fim de semana, tudo em infraestrutura serverless.\",\n },\n tags: [\"AI\", \"TypeScript\", \"Data Engineering\"],\n content: `\n## The goal\n\nI wanted a personal API that could answer questions like: *\"Which midfielders in the Premier League have the best progressive pass ratio in the last 5 games?\"* — with fresh data, not a CSV from 2022.\n\nThe plan: scrape fbref → process and store → enrich with AI → serve via REST.

The tricky part is rate limiting — scrape too fast and you get blocked. I settled on one request per 3 seconds with randomised jitter:\n\n\\`\\`\\`ts\nasync function fetchWithDelay(url: string, minMs = 2000, jitter = 1000) {\n const delay = minMs + Math.random() * jitter;\n await new Promise(r => setTimeout(r, delay));\n return fetch(url, { headers: { \"User-Agent\": \"personal-stats-bot/1.0\" } });\n}\n\\`\\`\\`\n\n## AI enrichment\n\nAfter storing raw stats, a separate worker calls the OpenAI API to generate:\n- A plain-English summary of a player's recent form\n- Automatic tags (e.g. \"in-form\", \"injury-return\", \"high-press-specialist\")\n- A form score (0–100)\n\nThe prompt is simple but the output is surprisingly useful for filtering.\n\n## Result\n\nThe API now serves ~50 endpoints with sub-100ms response times (mostly from Val blob cache).
