Team Lead, Risk InfrastructureScope: risk decision making, data pipelines, ML related infrastructure, ...

In December 2017 the company has been acquired by J.P Morgan Chase Engineer in Risk Team.One of few engineers who rebuild WePay's core Risk signal and rule engine services from scratch. As a service owner, I am dealing with the whole tech stack (starting from docker containers and finishing with services UI).

till August 2010 - Google Moscowfrom September 2010 - Google ZurichI was dealing with a big part of company infrastructure. Publicly known services include: Borg, Google Web Server, Bigtable, GFS, Chubby lock service, MapReduce, Sawzall, Google indexing system, pub/sub, protocol buffers/rpc, SStable, RecordIO (http://en.wikipedia.org/wiki/Google_platform). I took part in whole cycle of product release process: developing, planning resources, canarying, releasing, load-testing, monitoring, being on-call. Main programming languages were C++/Python in Linux environment plus a couple of internal languages. Project: One of the core projects in Google Maps, mostly backend part. Our service has pretty big pipeline, storing many TB of data, working 24/7 with strict SLA and ability to easily scale horizontally.Project: Google Definitions and Google Dictionary. I was the main owner of Google definitions service (improving, releasing, maintaining) which later was incorporated into Google Dictionary. It was removed as a separate property but still available in Google search ( http://goo.gl/LhuIo ).

Project: Design Rule CheckingDescription: software for verification of IC’s design. DRC was used in Bindkey™ tools Rapid Window Checker, RapiDesignClean, RapiDesignFix and others.Responsibilities: geometry processing, transforming polygons to donuts (like in gds, removing negative polygons), execution graph validation and correction, resize operation, BoxIn operation, unique algorithms and techniques for effective layout checkingFor producing a photo-mask microchip design is created. This design is checked against process technology requirements which is something like script involving a lot of geometry operations. This process is CPU and resources intensive. Our job was to implement system which should execute such scripts very effiiciently.Project: Manufacturing Rule CheckingDescription: software for verification of results of lithographical simulation of IC’s design. Responsibilities: morphological operations, unique algorithms for reducing simulation area, optimizing simulated contours - reducing number of vertices (healing).Project: Hierarchical aerial image computationDescription: lithographical simulation using hierarchical database of IC’s designResponsibilities: hierarchy recovery after flat simulation.

Project: GameBoy Color gamesDescription: Games and tools.Responsibilities: Mostly developing utilities, games code parts.Project: GameBoy Advance environment utilitiesDescription: Utilities to make possible GBA development using MS VisualStudio and C++.Project: Game Boy Advance gamesDescription: Code parts in titles like Static Shock, Tony Hawk Pro Skater 2 (tile-based algorithm to make possible to display levels with strong limitation on currently displayed tiles number)Responsibilities: Wide spectrum of programming tasksProject: AlgorithmsDescription: Problems connected with tile structure of GBA graphics engine. Examples: Optimal distribution between layers with limitations; data storage with strong limitations on RAM and ROM; scrolling game engine (tile based) with dynamic tile allocation (cpu and memory critical); tile-based physics engine (prioritizing tiles to create pseudo-3d animated game map).Project: Adobe Photoshop Plugin “Pixus”Description: implementation of optimal filtering for best image representation on LCD displaysResponsibilities: Whole projectProject: Scanline based 3d renderer (implementation based on modified OPENGL/ES specs)Description: Developed primary for Brew and Series 60 mobile platformsResponibilities: Whole project
