Industry Experience
Engineering
Manager / Principal Software Engineer
Mavenlink /
Kantata | Apr 2017 - Dec 2023 | San Francisco, CA
- M-Bridge Integration Platform (2 years): Led the
team that rearchitected an agent-based pipeline platform performing
multi-system data orchestration across many external systems. Took it
from chronically unreliable to dependable: established operational
metrics and monitoring that reduced errors and incidents by
~100x. Executed a zero-downtime migration to
Kubernetes, including relational, document, and cache
databases, with no customer-visible impact.
- Infrastructure Platform (4 years): Recruited and
rebuilt the infrastructure and DevOps team from near-zero after mass
departures. Migrated the entire Rails monolith and surrounding services
ecosystem to Kubernetes. Transitioned a large legacy codebase to
cloud-native Infrastructure-as-Code tooling (Terraform, Ansible,
Kubernetes). Designed and operated CI/CD pipelines for secure
software delivery across multiple environments. Led the
migration off a segfaulting production MySQL stack to managed RDS,
eliminating an entire class of incidents.
- BI Data Pipeline (3 months): Led a transition team
to take ownership of the analytics data pipeline and migrated it to
Kubernetes.
- Reliability & Mentorship: Drove a sustained
reliability push that dramatically reduced on-call incidents and
improved team retention. Grew multiple junior engineers into
senior SWE and Engineering Manager roles; mentored engineers
across teams and led interviewing and hiring. Top Performer
Award, 2021.
