I’m a Fullstack & Design Engineer with 7+ years of experience building web and mobile products, from early concepts to production applications.
My core stack includes React, Next.js, TypeScript, React Native/Expo and Node.js. I’ve built APIs, payment integrations, real-time features and cloud services using PostgreSQL, MongoDB, AWS, Azure and Stripe.
I combine engineering with UI/UX design, responsive layouts, interaction design and motion. I care about typography, accessibility, performance and the details that make an interface feel intuitive and polished.
I’ve worked as a senior and founding engineer, collaborating closely with founders, designers and product teams. I’m comfortable owning projects from design through development and launch.
Technical capabilities: IT, APIs, Mobile Application Development, Messaging Application Programming Interface, Rapid Application Development, Integration (Software), Backend, Backend Programming, Full Stack Development, Web Technologies and Front End. Practical experience includes REST API development and integration, real-time messaging with Socket.IO, rapid prototyping and mobile/web application delivery.
