Experience

Platform Engineering Manager (Apr 2020-Now)

Clarity.ai

fully remote

VP Platform Engineering (Aug 2019 - Mar 2020)

Nextail Labs

fully remote / >30% Hands On.

As responsible for the platform department I was in charge of leading all cross-cutting efforts aimed at:

- Improving the development experience of the product/engineering team.

- Enable functional squads to efficiently develop their work (using a self-service platform).

- Establish the technological and architectural bases of our platform (app framework, monitoring, scheduling, observability, domain events).

- Generate the necessary tools for the nextail operations and services team (including operational dashboards, operational DBs, automation of operational tasks).

Additionally, I acted as an Engineering Manager for the team (6 Engineers) (1on1s, motivation, mentoring, performance reviews) and as Product Manager for some of the initiatives.

These team effort has enabled us:

- Allow nextail to professionalize Operations and On-Call support.

- Improve overall system performance and resource utilization.

- Reduce cloud costs (by more than 25%).

- Reduce the toil in the engineering department dramatically.

Technologies: AWS (EC2, EKS k8s, Aurora RDS), Kafka, Redis, Python, RoR, Go, Immutable infrastructure, Infrastructure as code (terraform), Prometheus, Datadog, Grafana.

VP Engineering (Feb 2018 - Aug 2019)

Nextail Labs

fully remote / >10% HandsOn.

As responsible for the engineering team, I was in charge of doubling the size of the team and grow from a group of very talented engineers to a product delivery organization with shared practices and values and organize in squads aligned with the fast scalability need of the business.

This goal required:

- Hire and onboard 13 engineers

- Introduce better testing and development practices with Continuous Delivery as our goal.

- Help with the creation of the Product team and with the definition/introduction of the Product delivery processes.

- Improve the resiliency and stability of the platform (Incident management process, infrastructure as code, k8s migration, improved observability, and monitoring)

- Act as a technical reference regarding cloud-native designs, scalability, splitting the monolith, and so on.

- Act as an Engineering Manager for the team (+20 engineers) (1on1s, motivation, mentoring, performance reviews).

This team effort has enabled us:

- Changing our strategy toward whales (clients x10 in size).

- Deliver new features and modules (each squad autonomously).

- Improve our stability and introduce enterprise-grade SLAs.

- Reduce the number of production incidents drastically.

Technologies: AWS (EC2, EKS k8s, Aurora RDS), Redis, Python, RoR, Go, Immutable infrastructure, Infrastructure as code (terraform), Prometheus, Datadog, Grafana.

As responsible for the architecture of the platform, I helped to create an evolutionary architecture for the product (implemented using ideas from DDD, microservices, reactive systems, cloud-native design).

- Architecture and practices optimized for:

- Elasticity ranging from 40 to more than 2000 machines.

- Continuous delivery, rapid changes, and evolution

- Fault tolerance and high availability

- Autonomous teams and independent deployment

Advocate and change agent for the introduction of XP and modern agile values and practices (TDD, continuous delivery, infrastructure as code, collective ownership, emergent and straightforward design, courage, clean code). Working as a practitioner and also mentoring the team.
