SYSTEM ALERT: High Toil Level Detected. Alerts actively buzzing.
Site Reliability & DevEx Engineering

Crafting systems that let engineering teams breathe.

I am a Senior Site Reliability Engineer dedicated to eliminating operational toil and refining developer workspaces. Currently structuring self-healing reliability platforms at Netflix. I design infrastructure with the patience of a baker, the efficiency of an EV drivetrain, and a deep focus on team Quality of Life.

Reliability Log & DevEx Impact

Senior Site Reliability Engineer

Netflix
09/2025 – Present
  • Reliability consultancy for internal product teams, setting standard SLO metrics, error budget definitions, operational assessments, and post-mortems.
  • QoL Impact Developed an automated meeting transcriber and action-parser, converting sync meeting transcriptions into actionable markdown tasks to decrease recurring sync time by 30%.
  • QoL Impact Engineered local runbook caches stored directly within platform CLI tools to safeguard runbook availability for developers during cloud connection outages.
🧘
100% Uptime for Engineers.

Sync toil removed. Outage panics controlled. Team rests easy.

Site Reliability Engineer

Okta CIC (Auth0)
07/2023 – 08/2025
  • Secured GitHub Actions deployment pipelines using AWS SSM Parameter Store and OIDC integration patterns.
  • QoL Impact Built internal platform CLI tools in Golang & gRPC and designed Slack chatbot commands to automate developer environment builds, removing 4 hours of weekly bootstrap tasks.
  • Constructed multi-tiered SLO alerting matrices to align alert routing directly with customer experience metrics.
  • QoL Impact Automated critical database maintenance operations, allowing developers to execute db reindexing on-demand safely without submitting manual sysadmin tickets.
  • QoL Impact Polished developer loop times by developing containerized sandboxes with immediate automated code-test loops.
  • Led service audits and production readiness reviews (PRRs) to optimize failover paths.
☕
Bootstrap Toil Terminated.

Self-service reindexing and local sandboxes created space for focused coffee breaks.

Junior Site Reliability Engineer

Atlassian
08/2022 – 06/2024
  • Optimized message queue nodes using CPU-based horizontal autoscaling, shaving off 20% in public cloud costs.
  • Updated system sidecars across critical services, utilizing minimal distroless base images to reduce vulnerability alerts.
  • QoL Impact Created automated markdown documentation generator representing internal service SLO definitions, eliminating manual wiki upkeep.
  • QoL Impact Programmed developer shortcuts into the shell tools, optimizing local workstation environment tasks.
  • QoL Impact Designed and built single-click JVM thread-dump collectors to enable developers to debug performance bottlenecks without requesting server access.
  • Drafted technical incident reports and worked on feedback loops to mitigate recurrence patterns.
🔋
Diagnostic Blockers Removed.

Thread dump self-service keeps developers in flow state. Zero security request overhead.

Cloud Delivery Engineer

PwC Advisory Poland
04/2022 – 07/2022
  • Assisted in engineering security baselines and structured multi-account AWS Landing Zone blueprints for core banking workloads.
🏦
Foundation Set.

Structured, compliant landing zones that prevent downstream configuration problems.

Cloud DevOps Engineer

EPAM Systems
03/2021 – 03/2022
  • QoL Impact Restructured CI/CD cache key logic on GitLab CI, cutting average build waiting times by 25-30% across multiple microservice codebases.
  • Engineered database green/blue deployment procedures to switch active data warehouses holding over 100+ TB without downstream locks.
  • Configured Docker container patterns, Terraform infrastructure declarations, and Jenkins deployment runs.
⚡
No More Idle Coffee Walks.

Faster pipelines mean developers deploy while they chew, not while they wait.

Junior Java Developer

Vienna Insurance Group
10/2020 – 02/2021
  • Maintained Tomcat deployments, integrated MS SQL stores, and structured Java Gradle code, beginning an obsession with automation.
🌱
The Spark of Automation.

The moment toil was identified, and the drive to build platforms was born.

03 // THE CODE & THE CRUST

Two Crafts, One Mindset

CRUST RITUAL

Classic Country Sourdough

Pantry Checklist

  • 400g Sifted Wheat Flour
  • 300g Filtered Water (75%)
  • 80g Mature Starter (20%)
  • 9g Fine Sea Salt (2.2%)
01

Autolyse & Rest: Mix flour and water. Let it sit for 45 minutes to encourage gluten alignment before yeast enters.

02

Incorporate & Fold: Squeeze in starter and salt. Apply four sets of stretch-and-folds over 2 hours to build structural tension.

03

Cold Proofing: Shape into a banneton and ferment in a cold environment (4°C) for 16 hours. Development happens slowly.

04

The Bake: Bake inside a covered cast iron Dutch oven at 240°C for 20 minutes, then uncover to form a dark amber crust.

INFRASTRUCTURE RITUAL

Quiet Platform Uptime

Tool Checklist

  • OIDC Identity Security
  • Actionable SLO Alerters
  • Local Runbook Outage Cache
  • Self-Service Developer CLI
01

Autolyse Pipelines: Build clean environment templates. Let local testing modules run before cloud deployment scripts start.

02

Fold in Security: Incorporate OIDC role bindings. Automate secret rotation loops to reduce administrative security tasks.

03

SLO Proofing: Test alerts against realistic user budgets. Keep thresholds cool to prevent team pager alert fatigue.

04

The Post-Mortem: Uncover systemic failures. Review incident details collectively to feedback lessons into automated shields.
