Help marketing win via automation at scale.

Supported data engineering, analytics, and data science teams wielding big data technologies and domain subject matter expertise enabling digital marketing to reach its goals towards customer acquisition, retention, and enhancing share of wallet across entire funnel: Affiliates, CRM, Display & Paid Social, SEM, SEO. Helped harness Social Commerce with Walmart Creator.

SEM team is a part of Growth at Walmart Labs and is in charge of optimizing paid search for Walmart.com. The team is responsible for building infrastructure, data pipelines and API integrations enabling us to do so, with concerns of SLA and data quality squarely in focus, as well as building internal tools to provide our business partners control and visibility of SEM operations.As SMEs and thought leaders, partnered with channel marketers and product management to convince organization of possibility and led data science in implementing multi-objective optimization of SEM program to maximize profit and revenue.Ensured superb management of our multi-billion SEM program "at scale" by making sure as many items from our catalog as practical get exposure, while maintaining traffic quality (the "intent") regardless of amount of ad spend, using data science methods to dynamically modify bids on text and product ads across top search engine providers.

Worked with business partners in Marketing & Brand Partnership to define and execute product roadmap.Acting as a product manager on cloud-hosted infrastructural projects utilizing Cassandra, MySQL, AWS, SQS, I led a distributed team developing essential infrastructure to position company for membership growth:* multi-channel communication platform for time-sensitive messages via email, SMS and push,* SEO & sitemaps, including mobile SEO and concerns of sitespeed,* analytics instrumentation,* contacts & referrals, all the while paying utmost attention to user's privacy and compliance with anti-SPAM regulations.Nurtured a culture of service ownership. Under my leadership, team built exemplary micro-services in terms of SLA, code quality, metrics, dashboards and alerting. Sticking to "hands-on" principle, I designed and code-reviewed all products delivered by my team and stepped in to help resolve production issues or code solutions for particularly challenging problems.Worked with my peers and cross-functionally to define engineering culture via transformative project, Continuous Deployment, leading and contributing to tracks:* near-realtime monitoring and alerting using Graphite, Nagios and Icinga,* performance testing using throughput model,* code quality,* service "canary" certification workflow,* shared development environment.

* Channeled an avalanche of projects into challenging opportunities for my teammates, while shielding them from distractions.* Engaged viral loops to ensure sustained accelerated growth of LinkedIn members and drove visibility into the funnel via comprehensive metrics coverage.* Helped growing a talented team of individuals that are able to "move the needle" on key business metrics while "doing the right thing" in terms of culture, technology, and processes.* Supported engineers on my team and outside in developing, maintaining of services handling 100,000s of transactions per second, utilizing my first-hand experience with coding, architecture. Instilled code quality standards by extensive daily participation in code reviews.* Supported management by providing regular reports, raising and addressing concerns, being point person during numerous metric deviation investigations.* Challenged partner teams to follow through on the key principles of LinkedIn culture: ownership, excellence, consistent results.* Spearheaded and drove Growth Metrics Monitoring initiative, focusing on automation of anomaly detection using instrumented impression data delivered to Hadoop using Kafka. Worked with metrics infrastructure team to define requirements, SLA, and to host data extracts in Pinot.* Overseen stabilization of invitations service, its further operationalization by migrating from ActiveMQ to Kafka and by sharding underlying database.* Helped to fulfill several company-wide initiatives, such as migration to REST.li, ensuring robust work of services in multiple data-centers, complying with data retention policies and recommendations, to name a few.* Actively participated in Technical Leadership Group, making sure the group was accountable and practical in its deliberations.

Technical lead within virtual teams formed around feature and infrastructure projects in agile environment of a successful start-up.* Drove multiple projects simultaneously, some to pay off technical debt, others to pave way for new features and to open headroom for future growth, yet others to increase productivity.* Early adopter, advocate and integrator of key new proprietary technologies: Voldemort, Espresso, REST.li. Supplied crucial feedback to project owners.* A "go-to" person and domain expert on some of the core technologies and systems, made it a priority to be available to answer any questions to unblock members of my team and peers. Mentored and encouraged engineers around me to take leadership of challenging areas and projects.* Architected software for scale and performance, with an eye towards efficiency. Proven ability to drive diverse teams to achieve consensus on a technological solution. Great at communicating value of a solution chosen.* Used variety of tools, including Java- and Spring-based SOA, backed by traditional RDBMS, with sharding, replication, as well as key-value stores (Voldemort, noSQL), and caching (memcached, ehcache) in a variety of topologies (in- and out-of process), to achieve business goals.* Led a team in developing innovative "as a service" software for abstracting diverse data stores by graph-like aggregation of domain models.* Closely worked with Operations to drive successful deployment of solutions via extensive performance certification and topology planning, prevention of single points of failure; proactively planned hardware utilization, instrumented software for monitoring and alerting, and helped in troubleshooting of unanticipated issues (devops, engops).* Helped to build an extraordinary team through participation in resume, phone screens; interviewing; "selling" the team, company, and the opportunity. Reporting to Senior Director, I have helped growing the team from 5 persons to that exceeding 100.

Hands-on technical lead both coordinating and participating in multiple projects geared towards increasing capacity and improving efficiency of infrastructure that drives Pogo with its use exceeding 400,000 PSU and poised for further growth. Driven technology roadmap for back-end services identifying projects, setting priorities, explaining benefits, and achieving consensus. Improved in-house SOA solution to allow seamless choice of running services in- or out-of process (local method invocation vs RPC). Conducted capacity planning and capacity estimation based on statistical analysis of production utilization data. Designed, evaluated several caching approaches (using ehcache, Terracotta, in-memory DB - Derby) with appropriate consistency guarantees (through centralized versioning and session-bound invalidation), exploiting vertical and horizontal data and service partitioning, consistent hashing and stickiness. Performed extensive performance tuning (where understanding of JVM ergonomics was essential) and redesign of high-volume system driving micro-transaction initiative. Introduced use of Spring framework for persistence and ease of componentization. Implemented innovative, web developer-friendly localization framework for JSP. Conducted integration of AOL's Screen Name Service (early precursor of OpenSocial/Open ID) into Pogo sign-on process.

Supported and evolved proprietary standards-based software representing Personal Information Management product available via the Web and via cell phones. Architected highly scaleable alert service to notify customers of upcoming scheduled events by SMS.Implemented calendaring application with Web GUI as well as the service and the protocol to synchronize calendaring data with clients running on cell phones. Enhanced other Web/J2EE applications making the platform of company's offering (personal information management on the go, including Contacts, Email and Calendar).
