Billing that silently fails. Webhooks that race. Subscription states that don't match reality. You built the product — now the payments are the part that won't cooperate.
I'm a senior backend engineer who fixes payment infrastructure. Scoped work, fixed price, working code when we're done.
Upgrades, downgrades, trials, prorations, usage-based billing. The edge cases that eat weeks.
Race conditions, idempotency, retry handling, event ordering. The invisible layer that breaks everything.
Dunning flows, smart retries, involuntary churn reduction. Revenue you're losing without realizing it.
Connect integrations, split payments, onboarding flows. The complexity most teams underestimate.
Almost a decade writing software. CS degree. Most of my career spent building backend systems where things either work correctly or money disappears.
There's no agency here. You talk to me, I write the code. I'm taking on early clients at introductory rates while I build out my payments practice. You get a senior dev at a fraction of what an agency would charge.
