)I started on the backend (Kotlin, Java, Spring Boot) and grew outward into TypeScript, PHP, and Rust across real production work at Folowise. My deepest build is a multi-tenant commerce engine (foloengine v3) that powers live storefronts. Alongside it I ship my own products, most recently EchoFlow, an offline voice-to-text app for Windows. I care about clean architecture, boundary validation, consistent error envelopes, and systems that behave predictably under load. I own work end to end, from API contracts to CI/CD.
How I approach production systems
- Input validation at the API boundary, with a single consistent error envelope.
- Stateless JWT auth, refresh-token rotation with reuse detection, and role-based access control.
- Tenant isolation enforced at the data layer (database per tenant, no cross-tenant access paths).
- Observability through structured logging, Sentry, and request tracing across services.
- Small reversible migrations, CI gates, and predictable rollbacks.
Press a hotkey anywhere in Windows, speak, and your words are typed into whatever app you are in. All on your own machine.
EchoFlow runs OpenAI Whisper locally on your CPU through whisper.cpp (models from tiny to large-v3-turbo), so your audio never has to leave the device. Push to talk, it transcribes, then auto-types the result. English and Arabic, with optional translate / clean / prompt modes powered by cloud providers (OpenAI, Anthropic) when you want them. It keeps a searchable local history in SQLite, updates itself in one click, evicts idle models from memory, and protects its own window from screen capture.
Built with Rust + Tauri v2 for a tiny, native footprint, a TypeScript UI, cpal for audio capture, and SQLite for history.
My deepest project. A multi-tenant commerce engine, not just a store.
The engine is the shared brain and control plane for a fleet of storefronts. It owns licensing, billing, capability authority, update policy, and operational visibility, while each website owns its own runtime commerce data (database-per-tenant isolation, no cross-tenant leakage). It ships a server-side PHP SDK plus a scoped browser JS client, Stripe-hosted checkout, and 30+ commerce HTTP endpoints. ADR-driven architecture, deployed through GitHub Actions CI, observed with Sentry, and already powering live production storefronts (FoloPrint among them).
