Freelance software developer for Chile — SII-aware, UTC-3, Spanish native.
I build software for Chilean startups and companies with full timezone overlap, native Spanish, and familiarity with the local plumbing — SII facturación electrónica, Transbank / Webpay checkout, Khipu transfers, the Santiago tech ecosystem.
Start a projectFull timezone overlap with Santiago
Argentina and Chile share UTC-3 (Chile has no DST since 2019 in continental zone). Your morning standup is my morning standup. Real-time collaboration on launches, code reviews, and customer calls without async lag.
SII e-Factura integrations I've shipped
The Servicio de Impuestos Internos (SII) e-Factura requirement is non-negotiable for Chilean merchants. I've built integrations emitting and receiving DTE (Documentos Tributarios Electrónicos), handling folios CAF, and keeping XML signatures valid. Not my first rodeo.
Payment rails Chileans actually use
Transbank Webpay Plus dominates — if you're doing e-commerce, you integrate it. But Mercado Pago is strong, Khipu is gaining ground for bank transfers, and Mach / Tenpo are emerging for wallet payments. I've shipped the full stack depending on merchant preference.
Start-Up Chile ecosystem familiar
Start-Up Chile alumni, Cornershop legacy, Cornerjob, NotCo — the Chilean tech scene punches well above its weight for Latin America. I know the ecosystem shape: smaller market than Mexico or Brazil, higher willingness to pay for quality engineering, English-competent founders.

Why Chilean companies hire cross-border from Argentina
Chile's tech market is strong but small. Santiago alone is the economic engine, and the top engineers there are either founders, employed at the unicorns (NotCo, Betterfly, Cornershop's exited stream, Fintoc, Xepelin), or working remote for US companies at USD rates. Hiring locally at senior level means either competing for that same talent or waiting six months.
Cross-border from Argentina is a practical fix. Same timezone removes coordination friction (especially important for a country that emphasizes same-day responsiveness in its business culture). Same language at native level means zero translation loss in technical discussions, contracts, SII integration specs, or customer-facing copy. And the rate structure is predictable — pegged to USD, invoiced via foreign services, simpler than hiring through a Chilean SpA for a short engagement.
Where this fits best: Chilean SaaS scaling cross-border (which is most of them given Chile's domestic market size), e-commerce merchants that need custom Webpay integration beyond what Shopify provides, fintechs building on top of the Chilean Open Banking API (CMF), and companies serving the Mercosur region that need someone comfortable with both CLP/ARS/UYU contexts.
Billing structure: invoiced as international services, typically under reverse-charge treatment on your side. Your contador can confirm the specifics based on your company's tax scheme (SpA, SA, etc.). Payment in USD via Wise or bank transfer is simplest for both sides; CLP if you prefer, at the observed exchange rate on the day of invoice. Contract pegged to USD protects both sides from peso volatility — same pattern most Chilean companies use with their other international contractors.
FAQs
Como servicios prestados desde el exterior. Desde el lado chileno, normalmente pasa por tu contabilidad bajo reglas de importación de servicios o RCE (retención), dependiendo del régimen de tu SpA o SA. Tu contador lo tiene resuelto si ya trabajan con contractors internacionales.
Sí — he trabajado con emisión y recepción de DTE, manejo de folios CAF, firma XML con certificado digital, y el flujo de validación del SII. Usualmente integro a través de APIs como Haulmer, Openfactura o la API directa del SII según el volumen del cliente.
Transbank Webpay Plus es el default por cobertura y confianza local. Mercado Pago si querés tokenización y recurrencia más simple. Khipu para flujos de transferencia directa sin tarjeta (popular en B2B y pagos grandes). Flow como agregador si querés múltiples métodos con una sola integración.
Sí cuando el proyecto lo justifica. Buenos Aires-Santiago es un vuelo directo de 2 horas, fácil de coordinar. Para proyectos largos con stakeholders senior, una o dos visitas presenciales hacen diferencia. Los costos de viaje se acuerdan aparte.
USD por default (Wise o transferencia bancaria internacional). Si preferís CLP, lo convertimos al tipo de cambio observado del día de factura. Rate pegado a USD para protegernos a ambos de la volatilidad del peso.
MVPs para startups Santiago-based, SaaS B2B, e-commerce con Transbank, fintech sobre Open Banking (CMF), tooling interno para empresas medianas, y cualquier proyecto que requiera integración seria con SII. Cómodo con agencias y directo con founders.
