You will get Stripe, Clerk, or FastAPI issues fixed in your SaaS app
Project details
I fix Stripe, Clerk, FastAPI, and API issues in SaaS apps, MVPs, and internal tools.
This project is for founders or small teams who already have a working product or demo, but something in the billing, authentication, backend, API, or deployment flow is broken, fragile, or unclear.
I can help with issues such as Stripe checkout bugs, webhook failures, Clerk authentication problems, FastAPI backend errors, API integration failures, config problems, and production setup issues.
I have built and deployed working Stripe payment and Clerk authentication flows in live SaaS/demo systems, including alexbachlej.com and Vrillsy SaaS. I understand both the code path and the trust risk around billing, auth, webhooks, and production setup.
You will get a focused technical rescue pass: I review the issue, diagnose the cause, fix the problem within scope, test and verify the updated flow, and deliver clear handoff notes.
Best fit: one clear issue or one fragile flow that needs to work correctly.

About Alex
SaaS & AI Rescue | Stripe, Clerk, FastAPI, Python
Roeselare, Belgium - 2:18 am local time
I focus on backend, billing, authentication, deployment, and automation issues that block a product from being used, shown, or sold.
Common problems I help with:
Stripe checkout bugs.
Webhook failures.
Clerk authentication issues.
Customer portal problems.
FastAPI backend errors.
Docker or VPS deployment blockers.
API integration problems.
Messy AI-generated code that needs a technical rescue pass.
My stack includes Python, FastAPI, PostgreSQL, Docker, Stripe, Clerk, Redis, Celery, Linux infrastructure, and API integrations.
I work best on focused rescue/debug/audit tasks with clear output.
Good fit: you already have a demo, MVP, internal tool, or SaaS product, but something is fragile, unclear, broken, or risky before showing it to users.
I can help you turn “it works somehow” into “we can trust this enough to move forward
