What I'm looking for

I’m looking for a technical leadership role where I can design high-availability backend systems, drive DevOps/IaC and CI/CD improvements, mentor engineers, and integrate AI-assisted tooling to accelerate delivery.

I’m a Senior Software Engineer and Technical Leader with 12+ years designing and delivering high-availability backend systems for large-scale digital platforms. I focus on system design, distributed systems, and microservices architecture—building reliable services and iterating fast with strong engineering practices.

In my most recent role, I drove code quality improvements and optimized bulk threat-processing pipelines for production workloads at massive throughput in Golang, while also delivering features and fixes on a Django REST API. I partnered with teams to resolve critical production issues across AWS, Nomad/Consul/Vault, and Redis, and I strengthened integration testing using Docker and Venom.

I lead cross-functional delivery by owning project planning, scalable architecture design, quality improvements, and trade-off discussions, while mentoring engineers to raise team capability. I’ve defined cloud architectures across AWS and GCP, migrated CI/CD from Drone CI to GitHub Actions, integrated AI-assisted development tooling into a large monorepo, and improved observability with Grafana and Apache Superset.
