Engineering with Intent.

I am a freelance full-stack engineer who builds scalable, production-ready software for high-growth businesses and founders. Since December 2021 (4+ years), I have designed and delivered over 20 production web and mobile applications spanning healthcare portals, education platforms, SaaS products, and booking infrastructure.

My primary specialization centers on React, Next.js, TypeScript, Node.js, and React Native, paired with robust backend services in Express and Laravel. I unite clean architecture with responsive, accessible user interfaces, predictable state management, and battle-tested API integrations.

[01] Architecture First

Designing data models and API contracts carefully before writing UI code.

[02] Product Ownership

Delivering end-to-end features from architecture to deployment and observability.
