What I can build
for your team

Whether you're starting from zero or untangling years of technical debt — I deliver clean, scalable data infrastructure.

Data Pipeline Engineering

End-to-end ETL/ELT design, orchestration, and maintenance. Bronze to Gold layers, CI/CD, and data quality baked in from day one.

BI & Analytics Dashboards

KPI frameworks, Power BI dashboards, and Streamlit apps that give your team the visibility they need to make fast decisions.

Data Warehouse Setup

Snowflake and BigQuery architecture, dbt modelling, and migration support. Build the single source of truth your company actually trusts.

Data Stack Audit

A structured review of your current data infrastructure with a clear improvement roadmap. Ideal for teams that suspect something is broken but don't know where to start.

Data Quality & Governance

Testing frameworks, documentation, lineage tracking, and governance practices that scale with your team as you grow.

Real-Time Streaming

Kafka and Spark-based architectures for companies that can't wait for overnight batch jobs. Built for scale, monitored for reliability.

Tech stack

Modern tools.
Battle-tested in production.

No legacy tools for legacy's sake. Every technology chosen because it's the right one for the job.

Social impact

Data for good.

Not every project is about revenue. Some of the most meaningful data work happens in organisations fighting for something bigger.

Pro bono & discounted work for NGOs and NPOs

I offer free or heavily discounted data consulting to non-profit organisations whose mission I believe in. If your organisation is doing important work and struggling to make sense of your data, let's talk. Good data shouldn't only be for companies that can afford it.

About

João Bernardo.
Senior Data Engineer.

Based in Lisbon, Portugal — working with clients across Europe and beyond. I've spent 6+ years building data infrastructure for some of the most demanding environments: banking, telecom, and energy.

I started Lusidata to do the same work with more autonomy and more impact — for companies I actually believe in. Startups that move fast. NGOs that fight for good. Teams that want data to actually help them make decisions, not just exist in a dashboard no one checks.

I work fully remotely and operate across EU timezones. I've worked with teams in Spain and Denmark and I'm actively expanding internationally.
