What I'm looking for

I’m looking for remote contract engagements through my own company, based in Porto and working with European business hours. I’m available to work with US clients remotely and can work until 20:00 Portugal time.

At Dataprof.io, I build data platforms from ingestion through reporting. For a NYC grocery delivery startup, I migrated the data warehouse to Snowflake with a redesigned schema and parallel run; queries became 5x faster and infrastructure costs fell.

For a US EdTech lender, I built an end-to-end platform connecting ad platforms and internal systems to executive dashboards. Its dbt transformation layer gave the business a single source of truth for CAC and ROAS by channel.

At Scentbird, I owned BI architecture for the data warehouse, pipelines, and reporting. The team migrated an in-house system running on a Postgres replica to Snowflake and dbt, and I built subscription and acquisition reporting for business reviews.

Through Dataprof.io, I also create ingestion and reporting systems for marketing and product teams, including server-side conversion tracking and embedded analytics. I’m currently building an AI analyst for ad-platform data and use Claude Code and AI agents daily for SQL, pipelines, analysis, and documentation.
