At Reality Labs:* hired and coached managers and managers of managers, org size ~50 people* improved Release time-to-market (45% improvement) for Meta devices through software, infrastructure and process changes* during re-prioritization pivoted the org with no attrition (vs 20% average)* proposed and supported new software initiatives - example: emulation to scale testing infrastructure and improve developer efficiency, changes to software build and evaluation process* ensured consistent engineering evaluation bar across three organizations of hundreds of engineers in size

Delivered Service Management platform that significantly simplifies service management and hosts Facebooks AI models, that became the basis of all service management at the company and started from nothing:* single solution integrating 30+ systems, reducing service creation from days to minutes* automate actions across dependencies to create / manage / delete services with clarity of outcomes* 43% of new services (thousands) on the platform a little over a year after release at the company level, saving tens millions of dollars through engineering efficiency improvements* personally led collaboration with AI org that resulted in all new machine learning models hosted on the platform that has enabled rapid experimentation in AI* hired, coached and supported Engineering Managers and Engineering Leads to accomplish those goals; as a manager of managers supported an org of 26 people

Led 4 teams that collectively redefined how Facebook planned and managed datacenter fleet from physical space constrained, through power delivery, network capacity all the way to hardware allocations - without the real-time component of service allocation.* supported over 22 engineers across 4 teams with help of leads and engineer manager reporting to me* delivered collection of software that enabled the company to optimize layouts and manage infrastructure of all Facebook datacenters* proposed and worked with the team to deliver an innovative solution that combines concepts of source code version control with automation for layout optimizations, enabling company to cheaply plan for millions of servers with minimal human interaction when not needed and fully manual overrides feasible when necessary

While working on software for Datacenter planning and optimizations:* helped fix hardware in Facebook datacenters by put few millions worth of equipment to use through creation of software that was able to monitor fleet of infrastructure devices across all Facebook datacenters (200k datapoints per region) - which completely replaced 3rd party purchased solution for the company at much higher speeds of operation"Honestly I was not sure how you were going to take all the mess and make it useful, and you did. This has been a problem since PRN1A was first launched you and you fixed it!" - Dan Cernagosky* created flows that enabled rapid error corrections in case of human errors (30x decrease in errors across 3086 devices that were misconfigured)* improved existing datacenter planning software by cutting memory usage by a factor of 2.5x* decreased risk of power failures in datacenters by improving visibility of power oversubscription and changing how limits are calculated - as a direct result of this work 65% cases of oversubscription were fixed* hired, onboarded and supported junior engineers on the teamOutside of main project work:* supported engineers throughout the company through various mentorship programs (bootcamp mentor, peer mentor etc.) for over 20 engineers through the life of those programs, two managers and one director"Even after graduating bootcamp Piotr was still available as a hands on resource to provide technical expertise and mentorship. When ever I had an advanced question about Facebook infrastructure Piotr was able to provide information or point me to the correct resource" - Mike Max

Worked directly with CEO on projects critical to the company and the board. Lead performance team with following goals:* optimize architecture and implementation of key Wikia features* build tools to increase productivity of other teams* facilitate communication between trans-atlantic teamsMade Wikia a pleasure to use with faster interactions and page loads:* consume less resources, decreasing page size by 48% on average using techniques such as dynamically loaded assets, lazy initialization and reorganized page structure.* halved page initialization time on the client for logged in users by re-architecturing JS code without dropping any features.* decreased page initialization time by 25% for logged out users by adopting more efficient caching infrastructure and restructuring asset versioning to improve cache hit ratio.* improved MedaWiki core performance, decreased CPU load and improved number of requests served per serverReceived WooWoo award. Given "to the person who went above and beyond and did something extra special to improve the experience of our users.". Roughly equivalent to "strongest performance within the half".

Developed software for Wikia based on LAMP / MediaWiki platform. Provided technical expertise in different areas of development. Responsible for evaluating and recruiting new employees.Highlights:* Social platform features: Message Wall, Notifications - Created scalable Notifications architecture in SQL / Memcache * Core platform features: Video infrastructure and handling, asset management - Made development environment 2,6x times faster by redesigning asset caching

Started by creating software for internal teams that improved planning, increased transparency and saved time by eliminating unnecessary steps from the process.Eventually moved to another department to design full suite of software used internally for staff management, sales, scheduling and organization. Deployed servers for the company and managed services.Software required to work with large data sets with high performance and reliability.

Developed Django based project written in Python. Used MySql for data storage. Worked on project design, visual UI interactions, technical architecture and implementation.Improved performance of the software by orders of magnitude for critical operations. Made UI responsive. Lead redesign of navigation to make product easier to use.

Build software to analyze websites traffic. LAMP stack.Worked with large data-sets. Optimized queries and architecture for large scale operations.Created attractive looking reports and data visualizations.
