What I'm looking for

I’m looking for a senior full-stack or AI/LLM application engineering role on a remote, high-trust team: TypeScript, React/Next.js and NestJS or Python on the back end, React Native when mobile is involved, and agentic systems (Claude, RAG, MCP) running in production. I value end-to-end ownership, clean code and continuous learning.

Full-stack engineer with 7+ years building production web and mobile products for US and global clients across healthcare, fintech, e-commerce and the Salesforce ecosystem.

Currently at Oktana (client: Sungage Financial), working on a solar-financing platform: a NestJS 11 GraphQL API, Prisma/PostgreSQL and four React portals, owning features from ticket to production release. Before that, Tech Lead at Jobsity for EverBetter, where I led a team of 3 shipping a HIPAA-compliant patient mobile app (React Native New Architecture, Expo) from architecture to App Store and Google Play, including a voice-driven clinical intake flow built on AWS Transcribe and Comprehend Medical.

On the AI side I build LLM systems with RAG and citations, multi-agent orchestration and MCP servers on Anthropic Claude and the Vercel AI SDK, with open-source projects at github.com/NeryC and a 12-article technical blog. I use Claude Code daily and review every line it writes.

Founder of AdminRent, a multi-tenant SaaS with Paraguay e-invoicing (SIFEN), and organizer of GDG Asunción. Based in Paraguay (GMT-3, full Americas overlap), English C1.
