Senior Software Architect

• Apr 2020 - Present

Main focus on cloud-first design, infrastructure, DevSecOps and Site Reliability Engineering (SRE) • Drive key decisions and best practices to adopt Serverless architecture principles, enabling high scalability, reliability, resiliency and security with no bottlenecks nor servers maintenance needed. • Designed and implemented bulk processing and ETL pipelines to/from the analytics SaaS (Snowflake) using a serverless/cloud first approach, allowing processing hundreds of thousands of records in a matter of minutes. • Designed the backbone of the Terragrunt/Terraform IaC with reusable modules, multiple SaaS providers and scripting to automatically and securely rollout the cloud infrastructure to AWS. • Introduced SRE best practices, from insightful application logs and metrics, to alerts and SaaS integration with OpsGenie and Jira, allowing detection of application and infrastructure issues within 1-2 minutes, and reducing the forensics analysis to 5 minutes or less. • Applied DevSecOps best practices with a mix of IaC + Single Sign On (Azure AD) + AWS IAM policies for access control, abiding by the least privilege access best practices, and centralized user provisioning. • Implemented a 100% cloud-managed CICD Pipeline in Azure AD, secured and scalable, allowing deploying any IaC or code changes to the AWS cloud.

Senior DevOps Engineer

• Nov 2019 - Apr 2020

Lead efforts in infrastructure as code, IoT real time communications and DevSecOps best practices for a telematics system hosted on the AWS cloud. • Took the lead to roll out AWS IoT for pub/sub communications with the field devices. Replacing the legacy XMPP protocol with a full cloud managed MQTT protocol scalability increased from thousands to millions of devices. • Continuously enhanced the IaC (Terraform) to roll out networking cloud infrastructure and resources tagging in a secured, error-free manner.

Cloud DevOps Architect

• Oct 2018 - Nov 2019

I was responsible for leading the DevOps team for the second and third level DNA sequencing analysis application. This role required wearing multiple hats, from coordinating operational activities across teams in multiple regions, to building and maintaining infrastructure automation, as well as deploying and monitoring the application on multiple environments and geographical regions. Working closely with the development team proved to be the best way to collaborate in finding and fixing performance issues, as well as improving the observability of the system. Show less

Enterprise Architect

• Feb 2012 - Oct 2018

During my journey at RA I had the fortune to live different stages of a startup, from the inception, to the explosive growth and into the transformation to a bigger, more formal organization. I performed different roles, including Enterprise Architect/DevOps Lead, Dev Manager and Dev Lead. During this period I learned to fully embrace the DevOps culture, and built the processes and tools to empower the developers to ship, monitor and enhance their systems. This philosophy, combined with a strong, common architectural foundation in a micro-services environment, allowed me and my team to make other teams (all 13 of them!) more productive, where they focused on building the logic, while we focused on the cross cutting concerns, templates and DevOps processes.
