You will get Secure Backend API with Auth, Queues, and Webhooks

Project details
You’ll get a custom-built, secure backend API engineered for scale and reliability. I design backend systems that go beyond code—they power real businesses.
🔒 Secure Architecture
Token-based auth (OAuth2, JWT), webhook security, and access control.
⚙️ Business Logic & Automation
Stripe billing flows, Twilio messaging, and automated queues with Redis.
☁️ Cloud-Ready Delivery
Deployed via AWS Lambda, EC2, or Docker with full CI/CD pipelines.
🛠️ Real-World Use Cases
Built for SaaS platforms, OTT/VoIP apps, CRM systems, and subscription services.
📦 What You Receive
Clean, modular code with full documentation and production-ready APIs.
With 13+ years of experience and 100% delivery on Upwork, I build backend systems that are designed to last—not patched to launch.

Wordpress plugin customization
We had to customize a membership management plugin so that when a membership expired, it would change the user's role to "expired". This way, another events management plugin could set prices for each role. Zeshan was able to create a plugin with this functionality working very well. He also implemented a business rule where the membership price is modified based on the renewal date compared to the expiration date. Zeshan was able to implement these features and also modify the frontend to notify the user of the discount.
When it came time to implement the solution, testing took time, dealing with different WordPress droplets, migrating the site between them, and more. With Zeshan's help, we were able to resolve everything.

Job Success
Lahore, Pakistan - 3:59 am local time
I have 15+ years in software development and work as a CTO, collaborating with founders and product owners to turn business requirements into reliable systems.
I work best on backend-heavy systems where details matter: clean data models, predictable APIs, and interfaces that match real workflows. You get a senior engineer who thinks through edge cases, tests critical flows, and ships changes in a controlled way.
What I deliver
• New web apps and portals (Laravel + modern UI)
• Features in existing products: modules, dashboards, reports, admin tooling
• API development and integrations: REST APIs, webhooks, auth, third-party connections
• WordPress work when it is engineering: custom plugins, WooCommerce customization, API-based sync
• MySQL/MariaDB: schema design, query tuning, indexing, performance fixes, legacy cleanup
Typical projects
• SaaS or internal tools: admin panel + API + database + frontend
• Business workflows turned into software: approvals, queues, scheduling, subscriptions, exports
• WordPress sites that require custom behavior (not just page building)
• Systems that need faster queries and more reliable data handling
Tech stack
• PHP, Laravel
• Vue.js, Quasar, React
• WordPress, WooCommerce
• MySQL, MariaDB
• REST APIs, Webhooks
• Redis (when relevant)
How I work
• Discovery: goals, constraints, success criteria
• Plan: scope, data model, API contracts, risks
• Build: incremental delivery with checkpoints
• Test: regression on critical flows and data integrity
• Handover/support: clean documentation and stable releases
Good fit if you want a senior full-stack engineer who can build from zero, or improve an existing product without creating new problems. Share your brief and current stack (or just the idea), and I will propose the fastest safe path to ship.
