Full Stack Architect & Freelance Developer
I'm the person behind juliobuilds, a technical product studio for operators and companies in the US. I studied at Universidad de Ciencias Informáticas (UCI), and I've spent my career building custom software for people with a specific problem to solve — from internal tools to production platforms, across industries like insurance, trucking compliance, healthcare, retail, and travel.
I write about custom software and digital transformation for operators on thejuliobuilds blog.

ExchangeYourVan
If you own a camper in Spain and want to travel the US, there's no good option. Flights don't carry vans. Fleet rentals are impersonal and expensive. There was no cross-border exchange platform for the van life community.
Campervan exchange marketplace for the van life community. Owners swap vans across borders using VanPoint — a points system that makes cross-border trips possible without shipping your vehicle or renting from a fleet.
GoExpirely
Small trucking fleets get DOT/FMCSA fines because a driver's CDL or medical certificate expired. No compliance department — spreadsheets and memory fail under pressure.
DOT/FMCSA expiry alert software for small trucking fleets in the US. Tracks CDLs, medical certificates, and annual inspections. Claude AI reads expiry dates from uploaded documents and generates automatic renewal reminders.
Orion
Internal ops platform for Devonic: task tracking (Jira-style), project documentation (Notion-style), and AI-powered expense management — receipt scanning with Claude extracts category, date, and amount in one click, plus monthly budget forecasting and optimization from previous spending patterns.
SherpaRocket
A customer messages on WhatsApp after hours and gets an answer the next day — by then they've already booked someone else. Appointments get double-booked because the schedule only lives in someone's head.
WhatsApp automation and scheduling for local service businesses. Answers messages when the team can't, keeps the calendar conflict-free, and flags customers before they go quiet.
Trranu
Medicare agents spend a significant part of every sales call looking up plan benefits, formularies, and in-network doctors manually — while the client waits.
AI-powered CRM for Medicare insurance agents. Real-time plan search and comparison, in-network doctor lookup, formulary checker, and a Medicare-context chatbot (AEP/OEP, D-SNP, Medicaid tiers) active during client calls. Agency dashboard with shared pipeline and statistics.
