Base Blocks tech

Base Blocks tech is a product engineering studio for fintech and other complex, data-heavy products. We work as a senior, embedded product team for founders and CTOs — the same engineers who shape the architecture stay with the product for years, shipping features and owning outcomes long after launch.

Since 2019, we've built and scaled fintech and data-heavy products end-to-end. For ICLUB, we automated KYC verification (5-7 days down to ~50 seconds) and built the mobile-first platform now managing €120M+ in assets for 25,000+ investors. For Asset Camp, we took a market-analytics tool from MVP to a SaaS platform used by 1,000+ investors and advisors. For DocBay, we built a two-sided healthcare marketplace with booking, teleconsultations, and clinic tools, launched in Portugal and expanded to France. We've also built a compliance-focused ETL module for a RegTech platform processing millions of records daily with encryption and audit logging.

Our core stack is Node.js, TypeScript, React and React Native, Java (Spring), AWS and Google Cloud, Kafka, PostgreSQL, Redis, and BigQuery. We use AI to speed up delivery and cut manual work — a practical multiplier on senior engineering judgment, not a buzzword.

We work in two modes: full-cycle product builds, from architecture through production, and dedicated product teams for companies that need continuous ownership of an existing platform.

Both are led directly by senior engineers working with founders and technical leadership — no junior staff reporting up a chain. Clients consistently point to the same things: clear communication, flexibility, meeting deadlines, and a team that pushes back on requirements rather than quietly building the wrong thing.

Small, senior team by design — fewer, deeper client relationships instead of high turnover across many accounts. If your product involves financial data, complex logic, or both, let's talk.
