During my time in Walmart I have delivered several critical systems while improving processes, eliminating bottlenecks, and embracing a strong DevOps culture.

My contributions have led to direct savings of over $20m, the reduction of production incidents to a historical minimum, and the creation of 3 new full-blown teams.

Some of the projects in my portfolio are:

As a Technical Lead, my top 3 responsibilities were to:

  • Design cloud-native systems, gather feedback, iterate and drive them to completion in a lean/agile fashion
  • Facilitate communications with stakeholders, other teams and functions (build trust, plan work, set expectations, provide estimates, report progress, eliminate waste, improve outcomes) often by traveling across sites
  • Work with engineers of all levels to help them take both their soft and hard skills to the next level and grow professionally

Some of the practices and technologies utilized:

  • Cloud-native development, Site Reliability Engineering, DevOps, Microservices, Event Sourcing, Data Engineering, DDD, CI/CD
  • Distributed Systems, Azure, GCP, Kafka, Kafka Connect, Docker, Kubernetes, Consul, Nomad, Scala, Java, F#, C#, CosmosDB, Cassandra, SQL Server, Spark, Hadoop, Hive, Presto, BigQuery, REST, GraphQL/Protobuf, Prometheus, Grafana, Splunk, Dynatrace, Azure DevOps, Jenkins, Slack bots, Git, Swagger, API Design, Jira
