Project details
I build production-ready AI agents and automation systems that solve real business problems — not prototypes that break in production.
With 20+ years of enterprise engineering experience (IBM, Hewlett Packard Enterprise, Walmart), I deliver AI solutions that integrate with your existing systems, scale reliably, and come with clear documentation so your team can maintain them independently.
What you get:
• Custom AI agents built with Python, LangChain, LangGraph, and your choice of LLM (OpenAI, Claude, Gemini, or open-source models)
• API integrations connecting your existing tools (CRMs, databases, payment systems, communication platforms)
• Automated workflows that replace manual processes and run 24/7 with monitoring and error handling
• Clean, documented code deployed on AWS, Docker, or your preferred infrastructure
• A working system delivered in 1-2 weeks, not months
I recently built a multi-agent orchestration platform from scratch: LangGraph pipeline with Playwright browser automation, FastAPI dashboard, email notifications, Docker deployment, and Cloudflare tunnel integration — all production-grade and running autonomously.

Frequently asked questions
About Juan
Senior Architect React/TypeScript Dev, Cloud, Fintech, Payment Systems
Belen, Costa Rica - 5:32 am local time
compliance tools, payment portals, and internal core banking
platforms that pass audits, scale under load, and ship on time.
8+ years building production-grade financial software across
Latin America and the USA. I've architected full banking core
systems from scratch, regulatory monitoring dashboards,
customer-facing portals for financial institutions, and
real-time transaction processing engines — not side projects,
production systems handling real money.
Core stack: React 18, TypeScript, Next.js, Node.js, Python,
MongoDB, PostgreSQL, AWS, Kubernetes. I work with PCI DSS and
SOC 2 compliance requirements, and have deep integration
experience with Stripe, Plaid, and custom payment rails.
Before freelancing, I led frontend architecture at a banking
core platform and held infrastructure roles at Hewlett Packard
Enterprise. I know how enterprise engineering teams think,
what CTOs actually care about, and how to deliver without
hand-holding.
Typical outcomes: 60% reduction in audit preparation time,
3x transaction processing throughput, zero-downtime system
migrations.
Available for immediate start. I respond to all proposals
within 2 hours and keep communication clear throughout.
If your fintech project needs someone who has actually built
banking systems — let's talk.
