Building a SaaS product, AI application, or backend system that needs to scale?
I help startups and growing businesses build secure, scalable backend systems that stay reliable as your product grows. Whether you're launching a new SaaS platform, integrating AI, improving API performance, or building real-time features, I focus on writing clean, maintainable software that solves business problems not just technical ones.
Over the past few years, I've contributed to production systems serving millions of users, optimized high-traffic APIs, automated payment workflows, and built backend infrastructure powering web and mobile applications.
A Few Recent Projects
• Bolt VPN — Contributed to backend systems supporting 50M+ downloads, optimized APIs handling 500K–1M daily requests, and improved response times by 30%.
• Sober House Hub — Built a multi-tenant SaaS platform processing $40K–50K in monthly transactions, with automated billing, invoicing, and property management for 50+ organizations.
• Family Locator Platform — Developed a real-time GPS tracking backend with encrypted communication, sub-second SOS alerts, and infrastructure handling 200K–300K daily requests.
• StepMate — Built a serverless backend running on Cloudflare for a mobile application with 400K+ downloads.
• AI Football Analytics — Developed computer vision pipelines using YOLO, player re-identification, and LLM-powered analytics for automated football video analysis.
What I Can Help You Build
* Scalable SaaS backends with Node.js, NestJS, Laravel, and PostgreSQL
* REST API development, authentication, RBAC, and API optimization
* Stripe subscriptions, payment processing, and billing automation
* Real-time applications using WebSockets, live tracking, and event-driven architecture
* AI integrations with OpenAI, Gemini, computer vision, and automation workflows
* Cloud deployment on AWS, Docker, Cloudflare, DigitalOcean, and CI/CD pipelines
* Performance optimization, database design, Redis caching, and backend architecture
I believe good backend engineering isn't just about writing code it's about building software that's reliable, secure, easy to maintain, and ready to grow with your business.
If you're looking for a backend engineer who understands production systems, scalability, and long-term maintainability, I'd be happy to discuss your project and recommend the best technical approach.

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.
