Project details
I'll build an appointment scheduling SaaS that’s fast to set up, deeply customizable, and built for real-world service businesses—not just 1:1 meetings.
What sets it apart is a workflow-first approach: teams can configure booking rules, forms, payments, notifications, and post-booking actions without hacks or plugins. It also supports multi-service, multi-staff operations out of the box (locations, staff availability, capacity, buffers), while staying simple for clients: pick a service → choose a time → confirm.
In short: Calendly-level simplicity for customers, but Cal.com-level flexibility for businesses—optimized for service scheduling and automation.

Build a Custom Stripe Cart Integration for Tilda
I’m endlessly happy that I trusted Asgar with this work
Beyond setting up Stripe, Asgar helped with integrations, internal account settings, and basically all 30000 questions I asked 😄
Everything was done quickly, professionally, and exactly the way it should be.
If you don’t know who to choose, choose Asgar, you won’t regret it!

Bulk Upload Stripe Coupon Codes via API
Outstanding Developer - Went Above and Beyond Expectations
I hired Asgar for what I thought would be a straightforward Stripe integration - bulk uploading coupon codes. What I got was exceptional service that exceeded all expectations.
Not only did Asgar quickly develop the script I needed, but he demonstrated true professionalism by recognizing that implementing it directly would require access to sensitive account details. Instead of taking the easy route, he took extra time to carefully walk me through implementing the script myself, ensuring my data remained secure while still delivering the solution I needed.
What impressed me most wasn't just the quick turnaround or technical expertise - it was his commitment to my success. He could have considered the job done after writing the script, but he stayed to ensure I could implement it properly and achieve my goals.
Asgar combines technical skill with genuine care for his clients' security and success. He's someone who thinks beyond the immediate task to deliver the right solution the right way.
Highly recommended - I will absolutely work with him again.
