What I'm looking for

I want to build and scale reliable payments and integration systems, work on distributed backend challenges, mentor engineers, and deliver measurable business impact in a collaborative, product-focused team.

I am a results-driven senior software engineer with 6+ years of experience designing distributed systems and building payments and integrations platforms. I have a strong track record of delivering high-impact features—redesigning payment architectures, building automated scheduling with Temporal, and integrating practice management systems under tight deadlines.

I excel in backend engineering with Golang, Java and Python, and have driven reliability and performance gains: processing $2B in transactions (2024 forecast), reducing bug rates to near zero for key flows, and cutting query I/O latency by 60%. I also mentor engineers, lead interviews, and collaborate cross-functionally to ship production-grade services.

I seek to continue solving complex systems problems, improving payment and integration reliability, and driving measurable business outcomes through scalable, observable services.
