About Me

I'm a freelance Senior React Native and Full Stack Developer with over 5 years of experience delivering scalable mobile apps and custom websites for startups and enterprises. Whether you need a freelance website developer, a freelance mobile app developer, or someone to own the whole stack, 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.

Why Me

Why Choose Me

01

5+ Years of Professional Experience

With over 5 years of experience in React Native and full-stack development, I've successfully built and delivered scalable mobile and web applications across industries including healthcare, CRM, fintech, and AI-powered solutions.

02

My Work Speaks for Itself

I believe results matter more than promises. Every project I deliver is built with clean code, attention to detail, and a focus on performance, ensuring clients receive a product they can confidently rely on.

03

Critical Thinking & Problem Solving

I don't just write code—I solve problems. I analyze requirements, identify potential challenges early, and design practical, efficient solutions that save time, reduce costs, and help projects succeed.

04

Secure & Reliable Solutions

I prioritize security, stability, and reliability in every project, ensuring your application is built using industry best practices to protect your business and your users.

For MedSpa & Aesthetic Clinic Owners

A Full Operations Platform, Not Just a CRM

I design and build complete operating systems for medspas and aesthetic clinics — clinical charting, front-desk scheduling, an AI-powered growth engine, a branded patient app, and payments, all built HIPAA-consciously from day one. See it in practice in the ADEPT MedSpa OS case study.

AI-Assisted Injection Mapping

Interactive anatomy maps for neurotoxin, filler, and body treatments, with facial-landmark tracking and a full history of past injection sites per client.

Full Clinical Charting

Patient charts with structured treatment records, before/after photos, and timestamped clinical notes — everything a provider needs before walking into the room.

Front-Desk Scheduling

Conflict-aware provider calendars and a patient registry built for the screen your front desk actually lives in all day, not a generic booking widget.

AI Growth & Campaigns

AI-scored leads, a campaign studio for AI-generated email/SMS/push content, and predictive treatment-demand forecasting — one system running the whole growth funnel.

Branded Patient App

Booking, treatment history, an AI chat assistant, and a loyalty program with tiers and referrals — all inside your clinic's own app, not a third-party marketplace.

HIPAA-Conscious by Design

Role-based access, full audit logging, and payment flows architected so financial data and health data never mix — built in from the start, not bolted on later.

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