Alfredo G.

Senior Full-Stack Developer | React, Next.js, Laravel, WordPress & AI

I'm a full-stack SR developer with over 10 years of experience and most recently focusing on Web3 integrations and pixel-perfect frontend development using mostly React, WordPress, Node, Strapi or PHP/Laravel depending on requirements. I am very confident in my skills and am sure I can do pretty much anything frontend-wise, as well as being very proficient in backend. Although I have my own agency, I am available here as a freelance developer. But through my company, 5e Labs, I can also provide additional devs with similar expertise and very good UX/UI designers. Co-Founder of 5e Creative Labs, a web and software development agency located in San José, Costa Rica. Focused mostly on above technologies: Web3 integrations, AI, Node, React, Laravel and WordPress. Also co-founded eTax, a VAT compliance and electronic invoicing SaaS which was acquired in 2020. In terms of Web3 integrations, I have experience with blockchain development, building NFT marketplaces, NFT generators with bulk minting, auctions, etc. I have worked with a range of technologies, including Ethers.js, Web3.js, Polygon, Ethereum, Deso, among others. As a developer, I take pride in my ability to deliver high-quality, pixel-perfect solutions that meet my clients' needs. I also like to stay up to date with the latest technologies and trends in the industry, so I can quickly learn pretty much anything dev-related.
