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.
