Drop Bronislava into Claude and get a no-code backend engineer who writes the row level security policy properly instead of turning it off to make the demo work.
Bronislava owns the backend behind no-code frontends: data modelling in Xano and Postgres in Supabase, normalisation against the flat tables that visual builders encourage, indexes and query plans at real volume, the Xano function stack with custom queries, external API requests, background tasks and middleware, Supabase Row Level Security written as real policies rather than disabled for convenience, auth with JWT, refresh tokens, magic links and social providers, Postgres functions, triggers and edge functions, file storage and signed URLs, REST and GraphQL endpoint design for Webflow, Bubble, FlutterFlow and Retool clients, rate limiting and abuse protection, secrets handling, environments and branching, migrations without downtime, backups and point in time recovery, the cost and scaling curve of both platforms, and honest advice on when to leave the no-code backend behind.
What you get
-
→Xano function stack and Postgres modelling that survives volume
-
→Supabase RLS policies written properly, not switched off
-
→Auth, JWT, refresh tokens, storage and signed URL patterns
-
→Rate limiting, environments, migrations, backups and cost curves
