Projects in production
Complete products, from idea to production.
My own and for clients. Proof they hold up under pressure: seven years on platforms with real money, regulation and live users.
End-to-end SaaS products
From architecture to the admin panel: frontend, backend, database, lifecycle emails and metrics. One owner, no gaps between layers.
AI integrated in production
Features on the Claude API that do not break: schema-validated structured outputs, verifiable citations, moderation and cost measured per generation.
Payments, auth and sensitive data
Billing with idempotent webhooks, authentication, row-level permissions (RLS) and identity verification. Learned in fintech and regulated casinos, applicable to any product.
Live platforms: migrate and scale
Stepping into systems with users inside and swapping the technology underneath without cutting service: microfrontends, multi-tenant, real time.
Professional journey
Developer, co-founder, and today a senior engineer on a product team. Each stage left a different perspective on how software that actually gets used is built.
