As a Team Lead for the Site Reliability group, I define road-maps,
milestones, and identify areas where SREs can partner with different
teams to improve overall reliability of our infrastructure and services.
Key projects and responsibilities include:
- *Cell Architecture Implementation*: Led the SRE effort to transition
from monolithic Compute clusters to a Cell architecture, significantly
enhancing Roblox's infrastructure resilience and efficiency. Developed
migration plans, identified necessary automation, and drove production
readiness for this critical reliability improvement.
- *Edge Infrastructure Migration*: Spearheaded the migration from
HAproxy to Envoy at the edge, aimed at reducing failure domains,
improving performance by streamlining the proxy chain, and enabling
user traffic steering to specific cells from the edge.
- *Active/Passive Reliability Lead*: Orchestrated the failover strategy
across multiple teams, developing detailed action plans and validation
procedures. Conducted comprehensive tests to ensure plan
effectiveness. This work reduced the amount of time for a fail-over
from days to hours.
- *Reliability Culture Champion*: Mentored engineers of various levels
(both SREs and SWEs), established a model for production readiness,
and popularized the practice of running failure exercises for new
large infrastructure projects.
- *Technical Leadership*: Acted as tech lead on numerous projects,
demonstrating strong cross-team collaboration skills. Provided
technical guidance and mentorship to the SRE team, fostering a culture
of reliability and continuous improvement.
Key strengths include driving complex infrastructure projects,
mentoring, setting reliability standards, and facilitating effective
cross-team collaboration.

*** Key Achievements and Responsibilities:
:PROPERTIES:
:CUSTOM_ID: key-achievements-and-responsibilities
:END:
- *Large-Scale Infrastructure Management*: Led SRE efforts for one of
the world's largest compute clusters (Mesos), spanning hundred of
thousands of nodes across multiple data centers. Defined KPIs and
improved automation for managing a massive fleet of bare metal
machines.
- *Kubernetes Adoption*: Spearheaded the initiative to adopt Kubernetes
for on-premise infrastructure, driving architectural decisions and
implementation strategies.
- *Cost Optimization*: Designed and implemented strategies that
significantly improved hardware utilization, resulting in tens of
millions of dollars in savings on hardware costs.
- *Tech Leadership*: Served as Tech Lead for a team of 6 SREs supporting
Compute infrastructure. Established critical team processes including
on-call rotations and postmortem procedures.
- *Cloud and On-Premise Expertise*: Led multiple efforts related to
Kubernetes deployment and management, both in cloud environments and
on-premise infrastructure.
- *Storage Systems Migration*: Successfully migrated all pub-sub systems
from bare-metal deployment to Aurora/Mesos, pioneering the adoption of
the Compute orchestration platform among storage teams. This
transition reduced operational overhead, decreased deployment times,
and enhanced overall system reliability.
- *Network Infrastructure Improvement*: Advocated for and implemented
the adoption of 10Gb+ networking in data centers, enabling significant
scaling improvements for storage systems.
- *Cross-Functional Leadership*: Served as the SRE Tech Lead for the
real time storage team, driving improvements in performance,
operations, and automation across storage systems.
I consistently demonstrated the ability to lead complex technical
initiatives, deliver impactful projects on-time, optimize large-scale
systems, and drive cross-functional collaboration to achieve significant
improvements in infrastructure reliability, efficiency, and
cost-effectiveness.

I was one of the early engineers joining Linkfluence in 2007. I led the
development of the company's crawler (web, feeds). I was responsible for
defining the early architecture of the company, and designed the
internal platforms (Service Oriented Architecture). I contributed to
multiple open source projects on behalf of the company and represented
the company at numerous open source conferences in Europe.
