What I'm looking for

I'm looking to build scalable web and mobile products where I can lead frontend architecture, deliver reusable systems, solve production challenges, and collaborate closely with product and engineering teams.

I build production SaaS and enterprise applications with React.js, TypeScript, JavaScript, and Next.js. At Stairs7 Solutions, I lead frontend engineering while staying hands-on with architecture, implementation, code reviews, and engineering standards.

I've built web and companion mobile applications for Aptster, a multi-role SaaS and community platform spanning authentication, marketplace, community, announcements, maintenance, and payments. I create reusable components, responsive interfaces, structured API layers, and scalable frontend patterns.

I work with REST APIs, GraphQL, Axios, TanStack Query, Redux, Material UI, and Tailwind CSS to deliver data-driven product workflows. I also develop mobile functionality using React Native, Expo, and Expo Router, including secure authenticated communication and centralized error handling.

I've supported delivery from GitHub commit through Vite builds, Amazon S3 and CloudFront deployment, and containerized backend workflows using Docker, ECR, EC2, ECS, and CodePipeline. I use AI-assisted development for exploration, implementation, refactoring, debugging, documentation, and testing, with human review for correctness and maintainability.
