You will get your Stripe webhook, checkout, or billing bug fixed fast and properly

Project details
Your Stripe webhook returns 400s, your checkout redirects nowhere, or customers pay and your database never updates. I fix exactly that — fast and properly. I am a senior full-stack engineer who ships real production payment systems, not tutorials. I run live Stripe billing with signature-verified webhooks and entitlement sync to Postgres on my own products, BigEarnings and Given. Most Stripe bugs come from the same handful of mistakes: verifying the signature against a parsed body instead of the raw buffer, non-idempotent handlers that double-grant on retries, listening for the wrong event, or success pages updating state the webhook should own. I find the real cause, fix it, and prove it with a live Stripe test event. I work in Node, Express, Fastify, Next route handlers, and Python or FastAPI, against Postgres, deployed on Fly or Vercel. Message me your error or repo before ordering and I will tell you straight whether I can fix it.

A few numbers:
• Led an 8-person platform team at Upstart running over $5B per year in lending decisions — cut application-to-decision time 35% and reached 91% automation.

• Web scraping & anti-bot — Playwright, undetected-chromedriver, session reuse, proxies, ingest-to-Postgres pipelines.
• API & webhook integrations — OAuth, Clerk sync, multi-provider REST and GraphQL glue, Discord and Slack alerting.
• AI features — streaming chat, prompt pipelines, OpenAI/Claude/OpenRouter, RAG.
Stack: TypeScript, Python, React, NextJS, Node (Fastify/Express), FastAPI, Postgres, Redis.
