Description

Background:

12+ years in corporate / private banking (HSBC, Barclays) before transitioning to data and product management. I understand how businesses operate, not just how databases work. This means I build systems that serve the business logic, not the other way around.

How I work:

I scope fast, communicate clearly, and deliver working systems. No endless discovery phases. No over-engineering. You get clean architecture, documented schemas, and something your team can maintain after I leave.

Industries I've worked with:

Real estate, finance, short-term rentals, operations-heavy businesses.

Stack:

Supabase, PostgreSQL, Edge Functions, Lovable (internal tools), API integrations. I don't write Python or heavy backend code. I design data systems and build functional products using modern tooling.

Languages:

French (native), English (fluent), Hebrew (fluent).

March 2023 - Today (3 years and 3 months)
Genève, Switzerland
I design and build production-grade databases and data infrastructure, primarily on Supabase/PostgreSQL.
Recent work:
Built the entire data backend for Lamap.ch, a real estate intelligence platform with +100k property records, +100 tables, complex relational schemas, owner-matching algorithms, and a bronze/silver/gold data pipeline. Zero legacy debt. Scales cleanly.
What I deliver:
→ Database architecture from scratch or restructuring existing chaos
→ Complex PostgreSQL schemas, RLS policies, Edge Functions
→ Data pipelines and ETL logic
→ Admin dashboards and internal tools (Lovable & similar)
Best fit:
You have data that needs structure. Or a product that needs a real backend. Or a Supabase project that's grown messy. You want someone who thinks in systems, not just tasks.
