I help startups and businesses build SaaS platforms, API integrations, automation systems, and custom web applications that scale from MVP to production. Most of my work involves developing SaaS products, multi-tenant systems, admin dashboards, and APIs where performance, structure, and long-term scalability matter. I focus on building systems that are stable, maintainable, and ready for real users, not quick fixes or temporary solutions.

In addition to core development, I integrate AI and automation into real systems where they add practical value. This includes AI-powered features, workflow automation, API-based integrations, and business process automation using tools like n8n, Zapier, and custom backend logic — not isolated demos. I follow a structured development approach: clear requirements, clean code, realistic timelines, and transparent communication. The systems I build are designed to be understood, maintained, and improved over time.

STRIPE CONNECT | STRIPE BILLING | STRIPE RADAR | STRIPE API | STRIPE CHECKOUT | STRIPE TERMINAL | FINTECH | SAAS | AI | PAYMENTS | COMPLIANCE (PCI DSS, GDPR) If Stripe is slowing down your product, breaking your billing logic, or causing failed payments you can’t explain, I can fix that. I’ve delivered 100+ Stripe integrations for SaaS and tech companies, and I’m a 4× Stripe Certified professional. You’re not getting a basic integration, you’re getting a payments system designed to reduce churn, recover revenue, and scale with your growth. I specialize in building Stripe systems that directly impact metrics like churn, AOV (Average Order Value), LTV, and checkout conversion rates. I don’t just plug APIs. I step into your architecture and make sure your billing, subscriptions, and payment flows are optimized end-to-end. I can help if you’re dealing with: 🔹 High checkout abandonment rates 🔹 Unexpected churn from failed payments or poor retry logic 🔹 Broken or confusing subscription upgrades/downgrades 🔹 Low AOV due to poor pricing or payment flow design 🔹 Inconsistent or unreliable webhook handling 🔹 Stripe setups that “work” but don’t scale What I can help you with: 🔹 End-to-end Stripe integration for SaaS platforms 🔹 Subscription architecture (plans, trials, proration, lifecycle logic) 🔹 Reducing churn with smarter retry logic and dunning strategies 🔹 Checkout optimization to improve conversion rates 🔹 Webhook architecture (reliable, scalable, no missed events) 🔹 Stripe account audits with revenue-focused insights 🔹 Advanced Stripe products (Connect, Sigma, custom workflows) If you already have developers, I can work directly with them or guide them through the correct architecture in live sessions. Most Stripe implementations leave money on the table. I help you close those gaps so your payments system actually drives revenue, not just processes it. If you want to improve conversion, reduce churn, or fix hidden issues in your Stripe setup, send me a message and let’s take a look.
