Project details
Stop losing customers and revenue to broken billing loops and unhandled Stripe events.
A payment gateway looks simple on paper, but standard tutorials fail to address edge cases. Dropped webhooks, out-of-sync database states, and racing conditions can quietly leak money or lock users out of your application.
I build secure, production-grade Stripe billing engines that scale. I write resilient backend code that tracks payment sessions, accurately monitors subscription lifecycles, and protects your app tiers.
What I Build Best:
Fail-Safe Webhook Architectures: Idempotent event listeners built to verify signatures, map payloads, and handle high-volume sync streams smoothly.
Multi-Tier & Usage Billing: Flexible systems configured for fixed SaaS subscription tiers, seat-based metrics, or consumption-linked billing.
Database State Synchronization: Persistent data mapping tying your user database (Supabase/PostgreSQL) directly to live Stripe object statuses.
Seamless Checkout & Portals: Secure checkout pipelines paired with official Stripe Customer Portals for zero-friction upgrades.
Let’s turn your checkout into a secure, automated revenue channel. Send a message to get started.

Hello
I hired Syed Ali to help build me a real estate platform to connect agents together and put more deals together within our brokerage. Ali did an incredible job completing my project, he worked hard and fast to get everything done within the short time frame I had. The quality of the work was great as well, anytime I had an edit or fix I wanted he was able to get it done perfectly. I highly recommend working with Ali for any MvP, SaaS, etc needs. I will not be looking elsewhere for future projects as I believe I have found one of the best. Thank you again for all the hard work, I could not be happier with the outcome. You can tell he has been doing this effectively for years and has extensive knowledge of this field.

Dev Work to Test Trip App
This was a short engagement focused on getting some backend routes wired up for a travel app MVP. Ali helped get a few key pieces in place during the early setup phase. Due to timing and shifting priorities, we kept this work limited — but in another context, we might have continued with a longer collaboration. Wishing him the best on future projects.

Karachi, Pakistan - 12:48 am local time
I usually join when:
• An MVP is partially built but not ready for real users
