Over the last 6+ years, I've helped startups and growing businesses build SaaS platforms, Stripe-powered products, marketplaces, healthcare systems, logistics software, and AI-powered applications.

I work with founders who already have an idea, an MVP, or an existing product and need help making it secure, scalable, and maintainable for the long term. A large part of my work revolves around SaaS architecture, Stripe billing systems, marketplaces, AI integrations, database performance, reporting systems, and multi-tenant applications. On the payments side, I've worked extensively with Stripe Subscriptions, Stripe Connect, Payment Elements, ACH payments, marketplaces, usage-based billing, webhooks, invoicing, subscription lifecycle management, and complex revenue workflows. On the SaaS side, my core stack includes Next.js, React, TypeScript, Supabase, PostgreSQL, Redis, .NET, C#, AWS, Azure, and Vercel. More importantly, I understand how these technologies fit together to create products that can continue growing without becoming difficult or expensive to maintain. 𝐀 𝐅𝐞𝐰 𝐄𝐱𝐚𝐦𝐩𝐥𝐞𝐬 𝐎𝐟 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐬 𝐈'𝐯𝐞 𝐖𝐨𝐫𝐤𝐞𝐝 𝐎𝐧 • Built a multi-tenant advertising and digital signage SaaS platform similar to Google Ads, allowing businesses to manage campaigns, banners, targeting rules, scheduling, analytics, and reporting. The platform processes millions of records while keeping dashboards and reports highly responsive through optimized database architecture, aggregation strategies, and caching. • Spent 3+ years helping build a large-scale logistics platform used by delivery operations across the UK. The system includes route optimization, order management, driver mobile applications, proof of delivery, real-time tracking, customer notifications, support ticketing, invoicing, reporting, and operational workflows. • Designed and implemented Stripe-powered subscription platforms and marketplace payment systems, including recurring billing, usage-based pricing, ACH payments, automated payouts, Stripe Connect onboarding, subscription lifecycle management, and webhook-driven automation. • Built AI-powered solutions using OpenAI, AI agents, RAG systems, document processing workflows, intelligent assistants, and business automation systems that reduce manual work and improve operational efficiency. What clients appreciate most is that I don't simply implement tickets. I spend time understanding the business behind the product. How customers sign up. How revenue flows. What should be automated? How permissions work. What happens when usage grows? Where the risks are. And how to avoid expensive mistakes before they happen. That business-first approach allows me to make better technical decisions and build products that continue working as the company grows.
