How I use AI to build, ship, and operate.
A short tour of real work I have shipped using Claude Code as the primary builder, with OpenAI Codex acting as peer reviewer on every meaningful commit. ChatGPT and Gemini fill the gaps for research and content. Each project below is a production system I designed, built, and run end-to-end.
HeyMiles · Award Flight Search Engine
A consumer-facing product I built end-to-end with Claude Code, inspired by seats.aero but rebuilt for the Brazilian mileage programs (Smiles, LATAM Pass, Azul Fidelidade). Frontend, backend, database and the heavy-engineering crawler layer that powers everything. The interesting bit is what users do not see: the scraping engine.

Public landing
AI angle: Hero, value proposition, search widget and rotating airline highlights all designed in conversation with Claude Code. From brand intent to final pixel, no designer in the loop. The whole consumer product was built solo with AI as primary builder.
Live search results
AI angle: Search experience built with Claude: filters, sort logic, deeplink schema, results card design, and the "Best Price / Fastest" tag system. Backed by data the crawler engine ingests on a 24h cycle and on-demand enrichment.
Programmatic SEO hub
AI angle: Generated route landing pages targeting long-tail mileage queries (1.2K monitored routes, dozens of dedicated landing pages). Claude wrote copy, schema markup and the data-binding logic that surfaces live numbers from the warehouse on each page.
Single-route landing
AI angle: Each route page renders live KPIs (best price, available flights, direct count, programs monitored) pulled from Supabase in real time. Copy and structured data generated by Claude, hooked into the same crawler-fed pipeline.
Editorial blog
AI angle: Aviation-news blog drafted with Claude from briefs. I curate the angle, AI writes the first pass, I edit for accuracy and tone. Same pSEO playbook from the Manifesto site applied to a different vertical.
Platform metrics
AI angle: 273K+ flights monitored per year, 750+ active routes, 23+ airlines, sub-2s search. Numbers that only exist because the crawler engine below holds together day after day.
Behind the scenes
The crawler engine
The hardest part of HeyMiles is invisible: a scraping infrastructure shipped solo with Claude Code as pair-programmer.
445Kflight records
1.2Kmonitored routes
50airlines
24hcache TTL
Reverse-engineered private APIs (Smiles, LATAM, Azul). Adaptive rate limiting, multiprocessing + asyncio, batch upserts.
FastAPI on Hetzner, Bearer auth, 10 req/min limiter, systemd + cron, 24h cache, email alerts on failure.
Manifesto Coworking · Operations Platform
Custom-built management system replacing 5+ disconnected tools at the coworking I founded. Every screen below was designed in conversation with Claude Code: from data model to UI, from copy to charts. AI did not just write code, it shaped the product decisions.
- Claude Code (primary builder)
- Next.js · TypeScript · Supabase
- Vindi API integration
- Recharts · D3.js
Delinquency dashboard
AI angle: Claude Code built the entire ETL pipeline that pulls subscription data from Vindi, normalizes it, calculates delay buckets, and renders the table. I described the operational pain in plain English, AI shipped working code in iterations.
Monthly reports
AI angle: Editorial layout, KPI hierarchy, and time-series logic co-designed with Claude. Granularity detection (daily / weekly / monthly), period comparisons with variance, and the revenue composition bars all came out of pair-design sessions with AI.
Meeting room calendar
AI angle: Reservation engine, conflict resolution, and pricing rules generated from a 2-page spec I wrote. Claude proposed the data structure, I challenged edge cases, AI revised. Shipped a fully working scheduler in under a day.
Live office map
AI angle: Pixel-style office layout with real-time check-ins, team presence, and last checkouts. Claude wrote the polling logic and the visual grid system. Pure side experiment that became a daily-used internal tool.
Competitor analysis
AI angle: I gave Claude raw notes from market visits. It produced the executive summary, the comparison tables, and the structured insights. Strategy doc turned into a living internal page in one prompt cycle.
Manifesto Coworking · Public Website & pSEO
The entire public website was built end-to-end with Claude Code: design, copy, components, lead-gen forms wired into the operations platform from Project 02, and a programmatic SEO engine generating 30+ long-tail content pages for organic acquisition. AI did the heavy lifting from layout to keyword research to copy.

Homepage, end-to-end with AI
AI angle: Layout, copy, hero composition, navigation structure and visual hierarchy were all designed in conversation with Claude Code. I gave brand intent, AI proposed sections and microcopy, I edited tone. Shipped a brand-correct site without a designer in the loop.
Lead form, wired to the operations system
AI angle: Multi-step form for the fiscal address product (plan, CNPJ status, contact, document upload). Claude built the validation logic, the conditional branching, and the integration that pushes leads straight into the platform from Project 02. New leads land directly inside the CRM, ready to be worked.
Reservation form for meeting rooms
AI angle: Booking request form (date, start time, duration, party size) feeding the same calendar engine shown in Project 02. Claude wrote the form schema and the API handoff in a single iteration, then refined microcopy until it matched the editorial tone of the rest of the site.
Top-of-funnel lead capture
AI angle: "Try a free day" lead form on the community page. Claude proposed the friction-light field set ("what do you work with?" instead of generic message), wrote the qualifying questions, and shipped the submission flow that drops a tagged lead into the internal pipeline.
Programmatic SEO content hub
AI angle: 30+ long-form articles targeting Brasília-specific long-tail queries (fiscal address, MEI rules, CNPJ change, coworking comparisons). Claude generated the keyword map, drafted each piece, structured them with consistent metadata, and the index page renders directly from MDX frontmatter.
Single article, AI-written and human-edited
AI angle: Claude drafted each article from a brief: keyword, intent, outline. I reviewed for accuracy and brand voice. Internal linking, schema, and reading-time were generated automatically. Result: real organic traffic on bottom-of-funnel intents that the team can convert through the same forms above.
Sistema DB · Curation, Inventory & ERP Integration
Operations platform for a fashion curation business: deep Bling v3 ERP integration, real-time sales enrichment, store credit engine, and curation insights. Built with Claude Code as the primary author, with OpenAI Codex running peer review on every meaningful commit. The dual-AI loop catches edge cases I would have missed and keeps code quality consistent across 48 API routes.
- Claude Code (builder) + Codex (reviewer)
- Next.js · TypeScript · Supabase
- Bling v3 ERP · OAuth 2.0 · Webhooks
- OpenAI Vision (OCR inventory verification)
Curation insights
AI angle: Interactive analytics: "How much curation do I need to sell R$ X?" with a slider that recomputes targets in real time. Claude built the inversion logic and the YTD chart that compares sales vs. curation cost. Codex reviewed the math and caught a rounding edge case at zero-input.
Inventory · Bling ERP integration
AI angle: Live inventory pulled from Bling v3 (OAuth 2.0, 7 endpoints, 400ms throttle). Bulk import button registers products in batches with exponential backoff. Claude wired the entire ERP layer; Codex flagged a retry loop bug that would have hammered the API on transient errors.
Finance dashboard
AI angle: Expenses, revenue, daily targets, and overdue tracking in a single view. Period switching (week / month / past month / year), bank balance tiles, and an aging table for overdue payables. Claude designed the schema, Codex reviewed the date-bucket logic to ensure timezone correctness.
Cash register · payment-method breakdown
AI angle: Daily reconciliation across 7 payment methods (credit 1x, installments, debit, Pix online, Pix in-person, payment link, supplier voucher). Webhook-driven: each Bling sale fires an enrichment pipeline (fetch → enrich → cache → mark sold). Codex caught a missing idempotency guard before it hit production.
Investor Portfolio Dashboard
Private dashboard built for a high-net-worth investor: patrimony, profit/loss, S&P 500 benchmark, top performers, asset allocation, and geographic distribution. Built solo with Claude Code in a few focused sessions; Codex reviewed the calculation layer. Client name redacted for confidentiality.
AI angle: Claude built the entire visualization layer (Recharts + benchmark overlay), the percentage and currency formatting, and the responsive grid. I described the IR-style report I wanted, AI delivered the working dashboard the same day.
