Cloud-native architectures, distributed systems and AI integration for SaaS, e-commerce and payment platforms.

Based in Buenos Aires, Argentina — working globally
About

Five years shipping software that businesses depend on.

I'm a Software Engineer and Team Leader with 5+ years of experience building and scaling production-grade digital products. My focus is on cloud-native architectures, API development and distributed systems for SaaS platforms, e-commerce and payment infrastructure.

I've led engineering teams and shaped technical strategy alongside C-level executives — translating business goals into executable roadmaps with strong focus on performance, scalability and time-to-market.

Lately, most of my energy goes into AI and LLM integration: production-grade RAG pipelines, autonomous agents and AI-powered workflows running on resilient infrastructure built for high transaction volume.

How I can help.

01

Engineering leadership

Lead distributed teams, define technical roadmaps and translate business goals into shippable milestones alongside C-level stakeholders. Hiring, mentoring, code reviews and Agile/Scrum execution.

02

Cloud-native architecture

Design and implement scalable systems on AWS — microservices, event-driven pipelines, multi-tenant SaaS infrastructure built for HA. Docker, CI/CD with GitHub Actions, Fargate and RDS in production.

03

AI & LLM integration

Production-ready RAG systems with vector search, hybrid retrieval (BM25 + dense embeddings), multi-step retrieval with re-ranking and agent-based workflows. Vector DBs, prompt engineering and evaluation frameworks.

04

Payments & high-volume APIs

High-volume payment systems (Stripe, Redsys): subscriptions, webhooks, automated reconciliation, chargeback handling and PCI compliance. REST and GraphQL APIs in Node.js, TypeScript, Laravel and Python.
