What I'm looking for

I'm looking to build scalable, reliable backend and cloud-native systems, modernize legacy platforms, improve engineering delivery through CI/CD and observability, and collaborate with teams on high-impact products.

I've built and maintained custom SaaS solutions for U.S. government clients at Pax Arctic, modernizing legacy backend systems to improve performance, reliability, and maintainability.

I design scalable microservices and event-driven systems using Golang, PHP, MySQL, Kafka, RabbitMQ, Redis, Docker, and Kubernetes. I've also improved CI/CD workflows, implemented observability with Prometheus, Grafana, and Loki, and supported secure, highly available systems within government compliance requirements.

Previously, I led backend development at Adnomaly Technologies and built time-and-attendance software integrating Raspberry Pi hardware and web applications at Strandum HR. I enjoy translating business requirements into practical technical solutions, supporting sound engineering decisions, and mentoring teams.
