Software developer building custom SaaS, fintech products and automations, end to end. I take ideas from architecture to production: web apps, dashboards, payment systems and internal tooling for founders and teams. The platforms I built have processed over $20M USD.
Based in Buenos Aires. Working remotely with founders and teams worldwide.
I build software to a spec and own the whole thing: architecture, backend, frontend, integrations and delivery.
- Web apps & SaaS: products with auth, data, payments and admin dashboards.
- Fintech & payments: KYC/KYB onboarding, provider integrations, settlement, multi-currency operations.
- Automation & internal systems: turning manual processes into reliable tooling.
- Landing pages & sites that are fast, measurable and built to convert.
My sweet spot is the ambiguous problem that has to run in production and can't be wrong.
End-to-end payments platform for business clients. I designed and built the architecture, backend, frontend, integrations and the operational backoffice. Scope: KYC/KYB onboarding, virtual accounts, fiat off-ramps, settlement rules engine, operations console. Role: sole technical owner, from architecture to production.
Payments and exchange platform for international operations. I built the financial provider integrations and the internal tooling the desk runs on every day. Scope: payments, OTC and exchange flows, provider integrations, multi-currency operations. Role: CTO / Technical Lead.
Automated auditing of codebases using orchestrated LLM agents. It turns a manual expert review into a repeatable, prioritized report. Scope: agent orchestration, automated analysis, reporting.
A Spanish-language tech-news site that runs almost on its own: an editorial AI pipeline selects, writes, fact-checks and publishes, with real guardrails (anti-plagiarism, cross-checking, a quality gate) and self-monitoring automations. Built end to end, live in production. Scope: LLM editorial agent, quality gates, Next.js + Python + PostgreSQL, auto-distribution and watchdogs.
A daily photographic journal focused on a calm, fast experience. Shipped to production with a strong bar on performance (LCP under 2.5s) and UX. Scope: performance-first frontend, Web Workers, E2E testing.
Multi-currency finance tracker with AI expense capture over WhatsApp and payment integrations. Scope: AI categorization, multi-currency, payments.
App for creating and sharing gift lists, with WhatsApp-driven virality and onboarding in under a minute. Scope: shareable lists, multi-user, mobile-first.
I publish some of my own tooling and contribute to projects I use:
- agent-fleet: a tiny, dependency-free framework for running scheduled agents (shell or LLM CLIs) on a single box.
- prod-playwright-audit: a cross-agent skill (Claude Code, Codex, Cursor) that safely audits critical flows of a deployed web app with Playwright, without ever mutating production data.
I think in systems, leverage and long-term cost. I make the architecture call, then ship fast and iterate with real users. Anything repeatable gets automated, and reliability and compliance are part of the product from day one.
TypeScript, React / Next.js, Node.js, Python, PostgreSQL / Firebase, payment and banking integrations, LLM agents and automation, Vercel / Cloudflare.
I pick tools that will still make sense in five years.
Have a product to build? A SaaS, a dashboard, a payment integration, an automation? I take projects end to end, from idea to production.
