Buenos Aires, Buenos Aires Province, Argentina
Full-stack engineer with 15+ years shipping end-to-end products across fintech, crypto, and consumer apps. I work best in high-autonomy environments: translating a founder's vision into scoped technical plans, making architecture decisions independently. I run an AI-native development workflow — Claude Code and Cursor for agentic coding, spec-driven development, and AI-generated test suites — which lets me ship production-grade MVPs solo at the pace of a small team. I also build with LLMs directly: API integration (Anthropic/OpenAI/Gemini), structured outputs, and rapid prototyping of AI-powered features.. I've taken products from zero to production with full ownership over architecture, delivery, and business outcomes — from technical decisions through deployment, SEO, and monetization. I've operated as the most senior technical voice in lean startup teams, owned integrations with financial infrastructure (PIX, blockchain, BaaS providers), and driven product strategy directly with founders. If the goal is to go from idea to shipped product quickly, I thrive in that environment.

Architected event-driven payment processing systems using Python/FastAPI and a message streaming architecture. Led end-to-end integration of PIX (Brazil's instant payment network) and third-party financial APIs — owning architecture design, implementation, and transaction processing logic. Designed and built backend systems for multi-currency payment workflows, improving settlement reliability and reducing manual intervention in transaction processing. Operated as the most senior engineer by tenure, making independent architecture decisions and driving technical strategy in a lean team with high autonomy. Designed a data-informed rate-limiting and traffic management architecture to improve system resilience under high-load payment scenarios. Architected an automated exception triage engine using Anthropic's API to resolve complex payment reconciliation discrepancies via structured tool-calling.
Owned the full-stack architecture and delivery of property management web applications — Python/Django, React.js, PostgreSQL — from requirements to production. Drove architecture decisions for scalable, multi-stakeholder workflows (clients, agents, operations), balancing rapid delivery with long-term maintainability. Led cross-functional collaboration across product, design, and business teams, translating ambiguous strategic goals into scoped technical plans and shipped features. Delivered performance optimizations and infrastructure improvements that meaningfully reduced latency and improved system reliability.
Architected and built microservices interfacing with live crypto markets in real-time, processing streaming data to feed analytical and trading models. Designed and owned a trading algorithm performance analytics platform: monitoring dashboards, control mechanisms, and optimization feedback loops. Owned backend architecture (Python, Django, Celery, async), data pipelines (Pandas, NumPy), and deployment (Kubernetes, CI/CD) in a fintech environment demanding high reliability.
Owned concept-to-production delivery of a news aggregator Android app — 5,000+ downloads on Google Play. Clean Architecture, RxJava, Firebase Analytics, AdMob monetization. Full technical accountability across the stack: Android native app + Python/Django REST API backend, Heroku deployment, CI with Travis, crash reporting, and remote config via Firebase.
Led development of the Ripio Bitcoin Wallet for Android at one of Latin America's leading crypto exchanges — owned architecture, features, and security implementation. Built and maintained critical backend features with Python/Django for blockchain integrations, wallet operations, and exchange APIs. Spearheaded development of an automated identity verification system using Python and ML, reducing manual review while improving onboarding security.
