AI Engineer
Sep 2026 – Present · United States · Remote
Leading engineering at an early-stage fintech and blockchain startup whose non-custodial app opens digital assets to everyday people through a generative interface. Working closely with the three founders and with specialists in blockchain and integrations.
- Built the eval suite that gates every release of a multilingual AI assistant: 1,000+ scenarios replicated in English, Spanish and Portuguese (3,000+ cases), with the agents passing 90%+. An LLM-as-a-judge in LangSmith, validated against human review, grades every run.
- Migrated the assistant from Agno to a multi-agent LangGraph system with cycles, financial tools, background workers, retries and failure recovery; Claude is the primary model, with DeepInfra and Vertex AI fallbacks, GraphRAG (Neo4j, pgvector) and Mem0 memory.
- Made agent responses 2× faster and cut tokens by 40% by removing redundant tool calls and tightening memory and context, verified with load tests and evals.
- Designed the structured-output contract that turns agent answers into generative UI in the React Native app: native buttons, cards and deep links into swap, vault and perps flows on live market data. Users confirm every transaction in a non-custodial Privy wallet.
- Re-architected the inherited backend and frontend around Clean Architecture, cutting build-and-deploy from about 1 hour to 10 minutes. Built the trading integrations and fee model on top: Hyperliquid perps (200+ markets), LI.FI swaps (100+ tokens) and Morpho, Aave and Compound vaults, tracked via webhooks.
Software Engineer
Dec 2025 – Sep 2026 · Argentina · Remote
Consultant on Payway's merchant promotions platform (350,000+ merchants, 13 countries).
- Built a GraphRAG assistant that passed 95%+ of a 500+ case eval suite, graded in LangSmith by a human-validated LLM-as-a-judge. Used LangGraph, Neo4j and PostgreSQL/pgvector, and added guardrails against off-topic questions and data leaks.
- Delivered the event-driven pipeline that ingested 20M+ historical promotions into production (S3 and SQS into a Python/FastAPI Lambda, then Java/Spring Boot and NestJS services on Docker and Kubernetes). Wrote tooling to replay loads locally and reconcile failed records.
Software Engineer
Dec 2024 – Dec 2025 · Bahía Blanca, Argentina · On-site
Primary engineer on the permissions back office of Argentina's largest consumer cooperative (2.7M+ members).
- Integrated 10+ internal systems into one admin experience through a Python/FastAPI BFF and a Next.js front end; a 10-minute manual permission lookup now takes under 10 seconds.
- Cut permission tickets and manual assignments by 80%+ and recurring assignment bugs by 95%+ by standardizing how new systems are onboarded.
Self-employed
