Available to hire
I’m a software engineer who spends my time building and maintaining production systems across the stack, from quoting and invoicing platforms for trades to academic research applications. I enjoy collaborating with product owners to translate loosely defined requirements into stable, deployable software.
Recently, my focus has been on backend reliability, data modeling in PostgreSQL, and integrating third-party services like payment gateways. I’m especially interested in getting security and data boundaries right as part of delivering valuable features.
