About Me

I'm a backend-leaning full-stack software engineer specializing in production systems, APIs, and cloud infrastructure. Over the past 5+ years, I've shipped end-to-end products for startups and funded ventures — often as the lead engineer — focusing on scalable architecture, payment and logistics integrations, and clean, maintainable code. I transform ideas into fast, functional, and reliable software across backend, frontend, and mobile.

kelektiv/node-cron

fix(crontime): fall back to UTC when resolved timezone is invalid

Fixed a crash in node-cron where an invalid or unresolvable IANA timezone string would break schedule resolution instead of degrading gracefully.
