I design and build systems that save a business time and show it how it's doing.
Transport, fair sales, bookings and fleet control: systems that real businesses use today.
Four systems in depth: the problem each solved and how it is built.
Built for a trucker who wanted to know how much he makes on each trip. It logs kilometers, liters and expenses, calculates the profit of every trip and records payments in cash and third-party checks, with a monthly dashboard. Each transport company only sees its own data.
It replaced manual bookkeeping at a stationery stall in a fair. Sellers take orders on their phones, the checkout receives them in real time and stock is deducted automatically, even when a payment is voided. Reports export to Excel and PDF, and several businesses run isolated from each other.
Apartment, villa, yacht and car rentals in Miami: bookings, photos for every property and reviews synced from Google. Behind it, an admin panel where the owner runs the whole business: properties, bookings, clients, payments, suppliers, PDF receipts and a monthly summary of how it went.
App to set and track goals, with an AI coach that reads your goals, pending tasks and reflections before answering, compares your progress with the year's and tells you honestly what is behind. It remembers what you told it across conversations and suggests up to 3 tasks you add with one click.
More systems, short. Tap one to open it.
Phone app for the solo blacksmith, mechanic, electrician or plumber who still keeps everything in a notebook and WhatsApp. It builds quotes the client accepts from a link and exports them to PDF, logs jobs, payments and expenses, and shows how much was left over in the month. Running as a pilot in San Francisco.
Replaces the hours-and-kilometers spreadsheet for a construction company's 48 machines and flags overdue services that nobody used to see.
My agency's panel for a client's whole cycle: lead, proposal, onboarding, tickets and billing. Each client's system reports tickets and health to it over an API.
Internal system that answers how much money came in and out and what is due to be collected. An AI agent predicts when more stock will need to be ordered and analyzes where the expenses go.
App for my own use to sort income and expenses, with an AI agent that analyzes my finances. Through a Telegram bot it sends me alerts and takes in expenses and income. It also analyzes my investment portfolio against my investor profile and every day reports the market close, highlighting the stocks I hold.
Technology migration for Coliseo San Francisco: their ERP's desktop application moved from .NET to JavaScript, packaged with Electron. The ERP's clients now use the new version instead of the .NET one, and the migration cut startup from 7 seconds to 2.
Desktop application to organize a business that connects truckers with grain producers to haul their harvests to port. It keeps every trip and, for each one, the waybill, payments and advances.
The tools I use every day to take a system from idea to production.
