Facundo Olano

I’m a software engineer with over 15 years of professional experience.

During the first part of my career, I worked as a web developer while completing my Software Engineering degree. Later, I specialized in backend development, service-oriented architectures, and distributed systems, using various technologies and programming languages (Python, Node.js, Clojure, Erlang, Rust).

I’m more of a problem-solver than a technologist; because I think that software development is primarily a human activity, I place a high value on communication and knowledge sharing. I try to keep a business perspective in software discussions and provide technical insight to non-engineers.

I tend to assume a leadership role in the teams I integrate, leading by example and from experience rather than title.

As part of the Real-time bidding team, I worked on design, development, maintenance and operation of the bidding service and its support systems.

Operations work included infrastructure set up, deploys, monitoring, and production incident handling.

Some of the work efforts I led at NextRoll:

  • Streamline and automate new exchange integrations, a process that went from a couple of months to a couple of weeks.
  • Automate the production deploy processes, reducing its time from 6 hours to 45 minutes.
  • Modernize and decomission several legacy systems.
  • Automate periodic tasks such as AMI and release package preparation.
  • Implement a system to pull canary deploy metrics from DataDog and process them with Pandas to diagnose canary deploy health.
  • Profile and optimize the server performance with the specific goal of infrastrcuture cost savings.
  • Redesign, prototype and future-proof systems in preparation for privacy-related changes in the Ad Tech industry.
