About the service

I create production-ready applications on Supabase — an open-source Firebase alternative that gives you the full power of Postgres instead of a closed document store. When you hire me, you get a backend you won't be ashamed to show a real database engineer: a clean schema with proper tables, foreign keys, indexes and constraints, plus row-level security policies that guarantee each user sees exactly the data they have access to and nothing more. For me, RLS is a full part of the architecture, not something bolted on at the last moment, so your multi-tenancy and role logic lives alongside the data and doesn't rely on a leaky frontend.

My work covers the entire Supabase stack from start to finish. I set up Auth with email login, magic links, OAuth providers and JWT claims built into policies; I add realtime subscriptions so clients get updates the moment a row changes; I configure Storage buckets with signed links and access rules for uploads and media; I write edge functions in TypeScript for webhooks, payments, scheduled tasks and any server logic that has no business in the browser. Everything is managed through version-controlled migrations, so you can recreate the database from scratch and move between staging and production without guessing.

On the frontend I tie everything together through the JavaScript client, React, Next.js or your framework, carefully handling sessions, optimistic updates and error states. I care about performance: I profile slow queries, add necessary indexes and use database functions and views where appropriate. Whether you're testing a new idea or scaling an existing product, I deliver maintainable code, clear documentation and a handover so your team can continue development. Let's turn your requirements into a reliable and secure Supabase backend.
