João Henrique Gouveia Sperandio
@joohenriquegouveiasp
I build production-grade agentic AI systems, secure execution infrastructure, and scalable distributed platforms.
BrazilWhat I'm looking for
At Adopt AI, I build agentic development infrastructure and own the security posture of the code-execution layer. I cut new-product onboarding from seven days to two or three hours by turning a recorded HAR file into a complete integration.
I re-architected sandbox infrastructure for long-running workloads, reduced cold starts from more than 90 seconds to near-instant, and designed distinct execution postures for SOC 2, LGPD, on-prem, and cloud environments. As an embedded engineer, I’ve delivered LLM-assisted forecasting and document-processing workflows for retail and CPA clients.
Previously at Perch Insights, I built multi-agent NLP pipelines that translate business questions into structured queries over client data. I introduced LangChain and LangSmith observability, hybrid PgVector retrieval, and release gates using 300+ real prompts and 400+ tests per client environment.
I began in full-stack and DevOps engineering, building Tickey’s ticketing platform at APPMOOVE to support 30,000 sales for a single event. Outside work, I’m building Aurora, an open-source privacy-first peer-to-peer AI assistant mesh using WebRTC, Rust, and WebAssembly as my MSc dissertation.
Experience
Work history, roles, and key accomplishments
Seven days down to two or three hours for new-product onboarding, through ABCD (Adopt Actions Built on Cursor), open-source agentic development infrastructure that turns one recorded HAR file into a complete integration: auth detection, API ingestion, schema mapping, generated workflows.
Schema inference now runs as a Mixture of Experts that classifies APIs from HAR recordings, with several exper
Six agents convert freeform business questions into structured queries against per-client data schemas: time resolution, measure and dimension matching, intent, sub-queries, sorting, filtering. GPT-4o-era models could not do it in one pass.
Retrieval moved from Pinecone to PgVector on Postgres, with naive top-K replaced by hybrid vector plus keyword search. Match quality on client measures and di
