Mukela K.

I'm a full stack developer specializing in React, Node.js, and TypeScript. I build production web applications that handle payments, user data, complex workflows, fintech platforms, admin dashboards, SaaS products, and AI-powered automation tools. As a full stack developer, I've shipped 20+ production applications for clients across the UK, Australia, South Korea, Hong Kong, Netherlands, and Zambia. My full stack development work includes Stripe payment systems processing automated payouts, admin panels managing thousands of users across multiple roles, real-time dashboards with WebSocket data feeds, mobile money integrations for African markets (MTN, Airtel, Zamtel), and AI features using OpenAI and Claude APIs. Most of my full stack developer projects involve taking a business idea or existing codebase and turning it into something that works at scale. I handle both frontend and backend development, building the user interface, designing the API architecture, setting up the database, and deploying to production. Clean architecture, documented code, and systems that don't break when you scale. What I work with most: Frontend: React, Next.js, TypeScript, Tailwind CSS, Zustand, Framer Motion Backend: Node.js, Express, Supabase Edge Functions, REST APIs, WebSockets Databases: PostgreSQL (Prisma), MySQL, MongoDB, Redis Payments: Stripe (Connect, Webhooks, PaymentIntents, Subscriptions), Mobile Money (MTN, Airtel, Zamtel) AI Integration: OpenAI GPT-4o, Anthropic Claude API, custom automation workflows Cloud & Deployment: AWS, Netlify, Railway, Vercel, DigitalOcean Industries I've worked in: As a full stack developer, I've built applications across fintech, healthcare, education, transportation, SaaS, e-commerce, and marketing automation. How I work: I handle projects end-to-end from architecture decisions to deployment. I work solo on most builds, but I also co-founded Fluxium Agency, which means if your project needs to accelerate or something unexpected comes up, I can bring in additional developers without missing a beat. You always deal with me directly no middlemen, no handoffs. If your project involves building a web application, integrating payments, setting up admin dashboards, or connecting APIs send me a message. I'll be honest about whether I'm the right fit.
