About Me

I'm a Senior React Native and Full Stack Developer with over 5 years of experience delivering scalable mobile and web applications for startups and enterprises. My expertise spans React Native, React, Node.js, TypeScript, Express.js, PostgreSQL, MySQL, MongoDB, Firebase, REST APIs, AI integrations, and cloud technologies.

I specialize in building production-ready applications with clean architecture, scalable backend systems, intuitive UI/UX, and secure development practices. I enjoy solving complex technical challenges through critical thinking and delivering products that create real business value.

(Yes, I've read the entire React Native docs. No, I still Google "how to center a div" sometimes. We don't talk about it.)

See how this plays out in practice in my services and featured work, or read more on the blog.

Designed a two-sided marketplace in React Native with Firebase-backed listings, map-based discovery, and payments integrated end to end.
Outcome
Live on the App Store and Google Play, handling the full rental lifecycle — list, book, and get paid.

Adept MedSpa CRM screenshot showing client scheduling and treatment history for medspas
Case Study — Healthcare / CRM

Adept MedSpa CRM
Challenge
Front-desk staff and providers needed one system for client records, treatment history, and scheduling — instead of paper intake forms, a calendar app, and a spreadsheet.
Approach
Built a CRM covering the full client lifecycle in React Native on a Node.js/PostgreSQL backend, designed around how a front desk actually works.
Outcome
Delivered as the clinic's day-to-day operations system, replacing a patchwork of paper and spreadsheets with one connected CRM.

Outcome
Delivered as a complete POS platform — fast checkout for staff, real-time inventory and sales visibility for owners.
