Andrei Cabrera

I turn ambiguous engineering problems into production systems teams can trust.

GraphQL platforms, AI-assisted workflows, and product execution — from Apollo Federation work at Hilton to LiftIQ, a bilingual fitness app I built and shipped solo.

What I work on

Platforms, agents, products.

Platforms

GraphQL platforms
Federation rollouts that survive contact with many service teams. Subgraph patterns owners can copy. Schema governance you can defend in review. Mostly pattern work and review work; gateway code is the easy part.

AI engineering

AI-augmented workflows
Agents, evals, MCP servers, prompt pipelines. The boring part of "AI features" is making them dependable enough to ship. That's where I help. LiftIQ runs on this stack.

Products

Production-grade products, shipped solo
I ship LiftIQ solo: SwiftUI on iOS, Claude as the reasoning layer, every recommendation traced back to peer-reviewed sport science. 466 tests, ~$8/month infra, real users.

Case studies

Recent work.

Solo product

LiftIQ — an iOS strength coach grounded in the ACSM 2026 Position Stand

iOS app shipped solo. AI-driven programming mapped to peer-reviewed sport-science guidance. 466/466 tests, ~$8/month infra.

Leading Apollo Federation adoption across many teams

What it takes to roll out federation as an org-wide capability — graph governance, schema reviews, migration paths, and the social architecture around the technical one.
