- Experience: 5+ years shipping production-grade systems for startups and enterprise teams
- Focus: Systems simplification, CI/CD automation, API design, reliability
- Location: Santo Domingo, Dominican Republic (Atlantic Standard Time, UTC-4)
- Remote: Remote-first; overlap-friendly with Americas & EMEA

## Skills Snapshot
- Languages: TypeScript, JavaScript, Python, Solidity, SQL
- Frameworks: Next.js, SvelteKit, React Native, FastAPI, Node.js/Express, Expo
- Data & Infra: PostgreSQL, Prisma/Drizzle, Redis, RedisGraph/Neo4j, Docker, CI/CD (GitHub Actions, CircleCI)
- Web3 & AI: Hardhat, ethers.js, Chainlink VRF/Functions, LangChain, vector DBs (pgvector, Pinecone), MCP integrations, OpenWebUI, Claude Code, Cursor, prompt/context engineering

## Core Capabilities
- Platform & DevEx: CI/CD pipelines, multi-env delivery, DX tooling
- AI Systems (RAG + Graph): Retrieval design, data modeling, FastAPI services
- Full-Stack TypeScript: Next.js/React + Node.js + PostgreSQL/Prisma/Drizzle
- Web3 Integrations: Solidity/Hardhat, Chainlink, ethers.js
