You will get Stripe Webhook Debug & Billing System Fix
Project details
Your Stripe billing is broken and it's costing you money every hour it stays unfixed.
I diagnose and fix Stripe webhook issues at the root — not temporary patches that break again next week.
I've built Stripe billing systems for multiple SaaS platforms. I know exactly where these integrations fail and how to make them bulletproof.
Common issues I fix:
• Duplicate webhook processing — same event handled twice
• Subscription status out of sync with your database
• Payment succeeds but database not updated
• Webhook signature verification failures
• Failed renewals and retry logic broken
• Stripe → database state mismatch
What you get:
✔ Root cause identified — not guesswork
✔ Production-safe fix delivered
✔ Written explanation of what was wrong
✔ Tested before handover
Not sure if this covers your issue? Message me first — I'll tell you within 1 hour if I can fix it.

Stripe API Fix and Laravel Socket Integration
I am disappointed with this developer's performance. A 15-day project extended to nearly 3 months without completion. They struggled with small fixes, were often unresponsive, and frequently asked irrelevant questions. Despite multiple attempts to guide them, they failed to deliver the expected results and continuously requested payment before any significant progress.

Job Success
Multan, Pakistan - 7:33 pm local time
I've shipped 50+ platforms — a government compliance system
for 5,000+ Pakistan Railways employees (World Bank-audited),
an AI module that cut manual data entry by 85%, FinTech
backends handling payments across UK, UAE and Europe, and
a YouTube-style video platform with WebRTC real-time chat
serving thousands of concurrent users.
If you need someone to write a feature and disappear, I'm
not the right fit. If you need someone who thinks about
schema design, security, query performance, and what happens
at 3x your current load — that's exactly what I do.
━━ WHAT I BUILD WELL ━━
► FinTech & Payment Systems
Stripe, JazzCash, EasyPaisa, Payoneer, Wise — idempotent
processing, webhook verification, multi-currency flows,
escrow. Built to PCI-safe patterns with proper error handling
and retry logic.
► Backend Architecture (Node.js / Laravel / NestJS)
RESTful and GraphQL APIs serving 10,000+ req/day under
200ms. Microservices with clean service boundaries.
TypeScript-first with full validation. Redis caching and
pub/sub for real-time systems.
► PostgreSQL at Scale
Schema design, migration strategies, index optimisation.
I reduced a government system's query time from 15 seconds
to 200ms. Connection pooling, partitioning, full audit
logging for compliance.
► AI / OpenAI API Integration
Production GPT-4 integrations with provider-agnostic
abstraction layers, cost controls, prompt versioning, and
fallback strategies. Not just wiring up an API — building
something that's safe to run at scale.
► Security & Compliance
JWT with refresh rotation, RBAC, OAuth 2.0, audit trails.
Passed World Bank security audit for a public-sector system.
I treat security as architecture, not a checkbox.
► Amazon SP-API / Shopify / E-commerce
Japanese marketplace integration, multi-vendor fulfilment
platforms, rate limit management, exponential backoff.
Real resilience patterns, not optimistic code.
► WordPress & WooCommerce (Custom & Complex)
Multi-vendor WooCommerce platforms with custom commission
logic, AJAX cart systems, ACF Pro integrations, and vendor
dashboards. WP Rocket + Cloudflare configuration. Custom
PHP plugins, payment gateway integration (Stripe, PayPal,
JazzCash), and performance optimization for high-traffic
stores. I debug codebases I didn't write — fast.
━━ PAST ENGAGEMENTS ━━
• Pakistan Railways (2021–2023) — Audit & Fuel Management
systems for 5,000+ staff. World Bank compliance. Query
optimisation: 15s → 200ms.
• YetiScanner AI (2024) — OpenAI GPT-4 document processing
for YetiForce CRM (Netherlands). 85% reduction in manual
invoice entry.
• Global Connect ERP (Bahrain, 2024–2025) — Oracle monolith
→ PostgreSQL microservices. 3× performance improvement.
• Ourstube Media (2025–present) — YouTube-style platform:
Node.js microservices, WebRTC, custom AdTech, 4-provider
payment abstraction. 60% faster video processing via CDN.
• Thread Production ERP (2024) — Multi-tenant Laravel 11
system for textile manufacturing. Complex RBAC across
multiple facilities.

━━ HOW I WORK ━━
I take a small number of engagements at a time so I can
give each one proper attention. I communicate daily, push
working code early, and flag risks before they become
problems. Timezone: PKT (UTC+5) — available for UK, UAE
and European business hours with overlap.
Whether you need it built, or need an architect to validate the plan and pressure-test the decisions before you build — that's work I do. If your project involves backend architecture, payment systems, AI integration, database performance, ERP/systems integration, or taking a messy codebase and making it production-ready, send me a message with what you're building. I'll tell you honestly if I'm the right person for it.
