Hire the Best Stripe Developers

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.

I help founders and businesses build, fix and launch mobile apps, AI Automations, SaaS platforms and web applications. A lot of my work involves taking over existing projects, improving unstable apps, cleaning up prototypes, and getting products ready for real users. I am comfortable working with non-technical founders, small businesses and teams that need clear communication, practical advice and reliable delivery. My background is a mix of software, payments and real business operations. I founded and developed Festival Currency, a live transaction platform used at events and festivals that processed over $30M in payments across mobile devices, QR workflows, RFID systems and unreliable network environments. I also spent nearly 30 years running a major technology retail store in Australia, managing 40+ staff and dealing with tens of thousands of customers over that time. That experience gives me a practical understanding of how software is used in the real world: staff workflows, customer service, stock, payments, reporting, warranties, operations and the pressure of systems that need to work while a business is running. I can help with: • Building Flutter, React Native, Native Android, Swift apps for iOS and Android • Developing Laravel backends, APIs and admin dashboards • Building React and Next.js web apps • Fixing and improving existing mobile apps and SaaS platforms • Turning prototypes into production-ready systems • Reviewing Supabase, Firebase, Stripe and app security before launch • Integrating Stripe, Stripe Connect, subscriptions and payment flows • Improving onboarding, authentication, booking and workflow logic • Building customer portals, staff tools and operational dashboards • Cleaning up overcomplicated systems before release I regularly work on: • Mobile apps and MVPs • SaaS platforms • Booking and scheduling systems • Payment and subscription systems • QR code and scanning workflows • RFID / NFC Intergrations • Customer portals and admin dashboards • Retail, POS, inventory and operational systems • AI-assisted, Cursor, Lovable, Base44, Replit and prototype-based projects • Operational apps used by staff, customers or field teams I am not just a code-only developer. I help think through the product, identify risks, simplify the build and explain technical decisions in plain English. Tech stack: Flutter, Dart, Laravel, PHP, React, Next.js, JavaScript, Node.js, Mern, PostgreSQL, MySQL, Wordpress, Stripe, Stripe Connect, Firebase, Supabase, AWS, Cloudflare, Vercel, Digital Ocean, Redis, WordPress, REST APIs, Native Android and iOS PLUS many more.

Your Stripe integration probably works. The problem is the silent 5% that doesn't, and you only find out when a customer complains or a payment goes missing. I fix and build payment systems that hold up: webhook handling that can't double-charge, subscriptions that stay in sync with access, and checkout that doesn't leak sales. I'm especially good at taking over an existing Stripe setup, finding what's actually wrong, and fixing it properly instead of patching around it. WHAT I DO • Stripe Checkout, Billing & Subscriptions — plans, trials, upgrades/downgrades, proration, cancellation • Stripe Connect — marketplaces, connected accounts, payouts, platform fees and escrow flows • Signed webhooks, idempotent event handling, retries and recovery for failed processing • Payment status ↔ customer access and entitlement synchronization • Failed payments, refunds, disputes, multi-currency and tax/VAT (Stripe Tax) • Auditing and repairing existing Stripe integrations, including taking over an unfamiliar codebase MY STACK Next.js, React, TypeScript, Node.js, Python (Django/FastAPI), PostgreSQL, Supabase, Prisma, REST APIs, AWS, Docker, Kubernetes and CI/CD. As a senior full-stack engineer I also fix the application around the payment flow — auth, roles, admin dashboards, APIs, deployment, testing and documentation. PROOF • 100% Job Success · Top Rated · $20K+ earned on Upwork • Modernized a payments platform serving 50,000+ users (CIP TopUp) — user base +80%, crash rate 38% → 0.2% • Built multi-vendor escrow payments (Chinese Wheels) and fintech/crypto products (Mataset) • Shipped AI automation: WhatsApp Business API chatbots, Telegram bots and GPT-powered products Have a payment issue? Send me the Stripe event involved, what your app did and what it should have done — that's enough to start.

Bolt, Lovable, Cursor, and Claude Code get you 70% of the way there. The last 30% is where I live. I review, finish, and harden AI-built apps, and I build production AI from scratch. If your app demos well but falls apart once live users hit it, saves that don't stick, a data model that buckles at scale, security holes you can't see, that's what I fix. I also build the AI itself: phone and voice agents that book appointments, agentic workflows, and full Supabase and Stripe backends. I know where these tools break because I clean it up for a living. One Lovable app owner described it as "fix one thing and five break." Reading the live database showed 58% of saved records on a broken save path, a missing stable id that wrote a duplicate instead of updating, so edits looked like they reverted. It traces to the generated backend, the data model and the save logic, not the features. Solidify that and the cascading bugs stop. Recent work: • A pre-launch security review of an AI-built multi-tenant research platform, read-only, fixed price. It found the server was already compromised: an unauthenticated hole had given an outside party root access for about a month, and a second flaw let a forged link walk past the walls between clients' data. The owner believed the app was reasonably secure. Client: "Your $375 paid for itself several times over." I then rebuilt the isolation layer, every table on forced row-level security, proven in both directions. • Architecture and security review of a veterinary operations platform serving hundreds of animal hospitals, built with AI tools: 158 database tables, 52 findings, including two live holes on the production domain. The live data also showed work orders had been stuck in "submitted" for 25 days, so I unstuck the pipeline that runs their operations. Review delivered four days early; hired the same week for the repair rounds. • Built and shipped a ticketing platform for an entertainment venue's tailgate events, live and selling ten days before the season opener. Stripe checkout, QR scanning at the gate, 39 edge functions behind it. The AI phone agent I run on the same account took 332 inbound calls in August. Client, during the build: "I was scanning a QR code in my kitchen last night with more enthusiasm than my wife thought was reasonable." • AI phone receptionist for a service business. It answers and texts customers in the owner's voice, books appointments, and writes them straight into their Jobber CRM: client, job, and visit created automatically, nothing re-keyed in the morning. 197 customer calls in 84 days, 76 jobs booked. I also got the texting cleared through carrier registration (A2P 10DLC), the step that stops most people because it's an external carrier review, not a code toggle. From the client's review: "He identified issues, opportunities, and technical details that even Claude missed when I was developing the original specifications." • Got a mobile app back into both app stores after four months of failed releases. Two blockers, neither of them visible in the code: an Apple developer agreement sitting unaccepted, which blocks every certificate and profile, and an Android upload key that didn't match what Google Play had on file. A previous developer had been stuck on this for months. I built the native toolchain from nothing on a machine that had none of it, shipped the first working build, and had both platforms delivered inside three weeks. They kept me on monthly to run releases. • Took a Lovable-built MVP to production: a creator marketplace that generated 150M TikTok views and paid out $15,000 to 200+ creators. Stripe Connect plus PayPal payouts, TikTok API, multi-tenant row-level security. Client: "Andrew got my MVP over the line and helped bring my vision to life." How I work: • Fixed price per milestone. You know the cost up front, there's no open meter, and you only move to the next piece once the current one is done and working. • Most engagements start with a fixed-price review. What it finds decides what's worth building next, so you're not paying for a plan before anyone has read the code. • I use Claude Code and Cursor to ship 2-3x faster, and I verify everything the AI touches. • Straight about tradeoffs and limits up front, especially on security work. • I explain technical decisions in plain English. Most of my clients aren't developers.
