7 years building production web applications for SaaS platforms, marketplaces, and B2B products. I specialize in multi-tenant, role-based architectures, typed data layers, and component systems that hold up across multiple applications.

I work with Next.js, React, TypeScript, Tailwind CSS, TanStack Query, Apollo, and GraphQL to build frontend systems that scale beyond the first release.


What I Build

Multi-tenant architectures

Role-based applications serving multiple user types from a unified codebase, with organization scoping, access controls, and protected views.

SaaS product interfaces

Feature-rich dashboards covering bookings, wallets, analytics, onboarding, settings, and everything in between.

Marketplace and platform frontends

End-to-end frontend systems for two-sided platforms with separate user, client, and admin applications sharing a unified design system.

AI document pipelines

LLM extraction with structured output, per-field confidence scoring, and source-linking back to the original document, wrapped in validation and retry logic.

CMS architecture

Sanity and Storyblok implementations with custom document and object schemas, conditional field logic, custom desk structures, and editor safeguards that keep non-technical teams from breaking routes.

Real-time interfaces

WebSocket and socket.io layers wired into cache invalidation so live data stays in sync without full refetches.
