🚀 Is your MVP taking months instead of weeks? 💡 Tired of hiring a Front End Developer who doesn't understand your business and just writes code? I'm a Front End Developer helping startup founders launch production-ready MVPs in 𝟮–𝟯 𝘄𝗲𝗲𝗸𝘀, using a clear, 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀-𝗼𝗿𝗶𝗲𝗻𝘁𝗲𝗱 development approach. As an Upwork Expert-Vetted React Front End Developer with a Master's in Computer Science and 7+ years of experience building scalable SaaS platforms, dashboards, and custom APIs, I translate complex tech into clear product decisions that drive results. Over those years as a Front End Developer I've worked with startups from idea stage to Series B, as well as enterprise clients like 𝗦𝗮𝗺𝘀𝘂𝗻𝗴, 𝗛𝗼𝗿𝗶𝘇𝗼𝗻𝘀, and 𝗕𝗲𝗻𝘁𝗹𝗲𝘆 - always focusing on fast delivery, clean architecture, and measurable outcomes. 💬 Here's what founders say after working with me as their Front End Developer: "𝘎𝘳𝘦𝘢𝘵 𝘦𝘹𝘱𝘦𝘳𝘪𝘦𝘯𝘤𝘦 𝘸𝘰𝘳𝘬𝘪𝘯𝘨 𝘸𝘪𝘵𝘩 𝘒𝘺𝘳𝘺𝘭𝘰!
