What I'm looking for

I’m looking for a team where I can build and iterate full-stack products with strong UI, secure authentication, and scalable architecture—collaborating in agile sprints to deliver maintainable features, dashboards, and reliable integrations.

I’m a full-stack developer focused on building scalable web products end-to-end—from landing pages and authenticated dashboards to billing, admin tooling, and secure access control.

In my recent work as a Frontend Developer, I developed and maintained large-scale applications including PMS, LMS, CMS, and ERP, using React, TypeScript, Redux Toolkit, React Query, and ShadCN UI. I strengthen frontend architecture and code quality through maintainable patterns, agile collaboration, and optimized state management and API integration.

On full-stack projects, I’ve implemented robust authentication (including Firebase Auth with Google/Apple sign-in), subscription workflows, and transactional email pipelines. I also build role-based admin experiences and production-ready deployments using Vercel and secure API integrations, including Stripe/Paddle payment flows and webhook-driven updates.
