GitHub and Gitlab profiles. Bio
Since early years in my professional career, Databases and Open Source had both a considerable predominance at work, and it eventually they turned into my specialization over other IT technologies and areas. As any other IT components, Open Source Databases, are not isolated from the inherent and forced evolution of the technology stacks and, as a DB professional, my main concern was to not split the database component from the whole architecture as it used to be an odd piece due to its complexity. That is, mostly, the reason of my profile being mutated during the last years and positions, converging into a Database Reliability Engineer with consistent knowledge of architecture and infrastructure - emphatically IaaC (Infra as a Code), manipulating databases as any other component through CD/CI and following the most modern HA concepts. Not mentioned, at least directly, I managed to support and implement full architectures on bare metal premises and major cloud providers (being OnGres, Google Cloud partner), both in virtualized environments as dedicated hosting.
Even tho relational databases are frequently mentioned in this resume (MySQL and Postgres respectively, among others), I do not circumscribe around these exclusively, as nowadays all different engines (KV, FTS, analytics/columnar store) are integrated in complex stacks and need to synergy efficiently in the data workflow.
Part of this mutation, I’m currently walking through Data Engineering role, integrating components and setting up Data Lakes for stream analytics and experiencing with different engines and models.
I had also co-founded CanalDBA, with the intention of agglomerating specialists and advocate Open Source Databases in Latam.
As a previous and totally unrelated experience, I worked at Federal Penitentiary Argentinian Force, as officer in several institutions, from medium to high security. External publications
