Senior Full Stack Developer | React, Node.js, SaaS, AI & Mobile Apps

Most developers build what you ask for. I help you build what your business actually needs. Whether you're launching a SaaS platform, developing a custom web application, or building a mobile app, I focus on creating software that's scalable, maintainable, and aligned with your business goals. Over the past 8+ years, I've delivered 50+ web and mobile applications across healthcare, marketplaces, logistics, fintech, business automation, and enterprise software. Most of my work falls into four buckets: marketplace/on-demand platforms, social and dating apps with real-time features, custom software built around a specific business process, and backend integrations (Twilio, Stripe) that other developers get stuck on. Technologies I work with: Flutter • React Native • React.js • Next.js • PHP (Laravel) • Python • Node.js • Firebase • AWS • MongoDB • PostgreSQL • Stripe • Twilio • OpenAI APIs 𝐖𝐡𝐲 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐫𝐞𝐡𝐢𝐫𝐞 𝐦𝐞: I scope before I code , you'll know what you're getting and roughly when, before I start. When something in the spec doesn't add up, I flag it early instead of building around it silently. And I hand off documented code, not a black box, so you're not stuck coming back to me for every small change. If you're building custom software, a marketplace, a healthcare or on-demand app, or need someone who can actually finish a Twilio or Stripe integration without three follow-up calls" 𝐥𝐞𝐭'𝐬 𝐭𝐚𝐥𝐤 𝐚𝐛𝐨𝐮𝐭 𝐰𝐡𝐚𝐭 𝐲𝐨𝐮'𝐫𝐞 𝐛𝐮𝐢𝐥𝐝𝐢𝐧𝐠."
