Hi I'm Alex, Senior Full-stack Developer with over 10+ years of experience in web-development. Now I'm specializing in TypeScript, React, and SSR (like Next.js, Astro.js, etc.) and I'm confident in my ability to contribute effectively to your team or work alone on your tasks: - investigate a business problem and solve it without an initial detailed description - research available solutions, choose the best one, and justify this choice - be scrupulous and detail-oriented, while understanding that sometimes a product needs to be launched as soon as possible - able to adapt to your stack and quickly learn missing technologies - used and created various APIs, understanding the needs of both front-end and back-end developers Core skills: TypeScript, React.js, Next.js, databases, styling, Material UI, Mapbox GL JS. I'd be happy to discuss whether I’m a good fit for your needs.
