Top SchoolAlejandro Do Nascimento is an engineering manager and backend/database-focused software leader with 11 years of experience building scalable telemetry, observability, and AI-enabled features at companies like TigerData (TimescaleDB) and New Relic. He leads teams that integrate vector embeddings, relational and time-series data to enable RAG, search and AI agents on PostgreSQL, while maintaining a hands-on approach to code and database design. His open-source contributions include backend and DB improvements to the well-known Promscale project, demonstrating practical expertise in Postgres ecosystems and pgx upgrades. Comfortable across languages and stacks, he has shipped production services in Go, Java, Python and managed migrations, low-downtime tooling and ingestion pipelines. Based in Barcelona and originally from Venezuela, he balances technical leadership with mentoring and cross-team collaboration to align product, design and platform goals. Outside work he’s a curious polyglot coder and an avid (if knee-complaining) futsal and padel enthusiast who brings that same playful persistence to solving hard engineering problems.
