What I doHire me when it has to work in production
Backends, APIs & automation
Node.js services that integrate real-world APIs — webhooks, Meta/WhatsApp, MySQL, retry and reconciliation jobs, reporting. Built for the failure cases, not just the happy path.
Rescue, fix & maintain
Inherited codebase? Crashing release? Long-term clients trust me with bug fixing, SDK migrations, performance optimization and careful maintenance of apps already in users' hands.
