Project details

Billing systems break in production more than any other part of a web app — failed payments, missed webhooks, subscription sync issues, and edge cases that only appear at scale.

I've engineered Stripe billing for a VPN platform serving millions of users across Web, iOS, Android & Chrome —
handling subscriptions, payment retries, and cross-platform entitlements without manual intervention.

What you get:
✅ Stripe checkout & payment flow setup
✅ Subscription plans with trials & upgrades
✅ Webhook handling for all payment events
✅ Failed payment retry logic
✅ Customer portal integration
✅ Invoice automation
✅ Apple Pay / Google Pay (Advanced tier)
✅ Full documentation & tested endpoints

I've handled real billing edge cases in production — not just tutorial-level Stripe integration. Your billing system will work reliably from day one.

Message me with your stack and I'll tell you exactly how I'd approach your integration.

Most backend projects fail at scale. APIs that choke under real traffic. Billing systems that break on edge cases. Code that becomes unmaintainable the moment you touch it.

I've spent the last few years solving exactly these problems. I'm new to Upwork. I'm not new to production systems handling millions of users.

✅ Production Systems I've Built
-- Bolt VPN — 500K–1M daily API calls | 50M+ downloads | 30% latency improvement | AES-256 encryption
-- Sober House Hub — $40–50K monthly transactions | 50+ organizations | 100+ properties | Zero-manual invoicing
-- GPS Family Locator — 99.999% uptime | 2–300K daily requests | Sub-second SOS alerts | AES-256 encryption
-- StepMate — 400K downloads | 1–3K daily active users | Serverless on Cloudflare
-- Veo Football Analysis — AI video analysis | YOLO + REID detection | Gemini analytics | Production-grade
Real users. Real traffic. Real consequences for failure.

✅ What This Means For You
-- Scale: I've handled systems from 1K to 1M+ concurrent requests. I know where performance breaks and how to fix it.
-- Reliability: 99.999% uptime isn't theoretical—it's what I've delivered in production. Every millisecond matters.
-- Security: Encryption, key rotation, threat detection. I don't cut corners on security.
-- Automation: Built automated billing systems processing hundreds of thousands monthly. Zero manual work.
-- AI Integration: Not just ChatGPT plugins. I've integrated computer vision (YOLO, REID) and LLMs where they solve real business problems.

✅ How I Work
-- Production-grade REST APIs with proper auth, RBAC, and full documentation
-- Multi-tenant SaaS architecture with automated billing (Stripe, payment systems)
-- Real-time backends — GPS tracking, live data pipelines, WebSockets, async queues
-- AI/Computer vision integration — Gemini, OpenAI, YOLO, REID, video analysis
-- Secure infrastructure — encryption, key management, threat detection, access control
-- Cloud deployment — AWS, DigitalOcean, Cloudflare, Docker, CI/CD pipelines

✅ Why Companies Work With Me
-- Not theoretical. I've optimized systems handling 1M+ daily API calls. I know what actually works at scale, not what looks good on Medium.
-- Proven results. 30% latency improvement. 99.999% uptime. $500K+ monthly transaction processing. These are measured, real outcomes.
-- Reliability. I build systems that don't break. That means robust error handling, monitoring, and infrastructure that scales.
-- Full ownership. I handle the complete stack—APIs, databases, security, deployment. You don't get half-finished code or missing infrastructure.

✅ Currently Available For
-- SaaS backend development (multi-tenant, billing, RBAC)
-- High-scale API architecture and optimization
-- Real-time application backends (GPS, live tracking, WebSockets)
-- AI/Computer vision/LLM integration into existing systems
-- Performance optimization and scaling existing systems
-- Secure infrastructure and database architecture

If you're building something that needs to actually work at scale—not break when you hit real traffic—let's talk.

Steps for completing your project

After purchasing the project, send requirements so Inam can start the project.

Delivery time starts when Inam receives requirements from you.

Inam works on your project following the steps below.

Revisions may occur after the delivery date.

Requirements & Billing Architecture Review

Review your stack, confirm which Stripe features are needed, map out the subscription flow, webhook events, and payment edge cases before writing any code.

Stripe Setup & Core Integration

Configure Stripe products, prices, and plans. Implement checkout flow, payment methods, and core API integration into your backend.

Review the work, release payment, and leave feedback to Inam.
