Internationalization, Universal Language Profiles team• Took ownership of the full release process automation of the Universal Language Profiles (ULP) team which produces all the binaries released for client use to production (end-users in the order of billions) • Designed system for full automation of the weekly release process for the Search Ads pipeline which removed week-long engineers manual work including job monitoring/execution and metrics analysis (implemented: Python, gRPC, protobuf) • Became full owner of the continuous integration test which performs an extensive binary sanity check (ensure quality) for all binary releases of ULP to production • Designed the improvement plan (fully gathered requirements) for reliability of the continuous integration test (of the ULP full pipeline) and implemented it, resulting in pass rate 24% → 90% and average execution time 5-6 hours → 3 hours • Proposed projects to improve the interaction/engagement with end-users and action items to improve the maintainability/reliability/coverage of the team-owned tests • Participated in week-long on-call sessions debugging/mitigating critical Prod incidents (~45/shift) and writing post-mortem (impact, mitigating actions, root cause, future prevention actions) for system outages • Contributed to the onboarding of ~12 new team members by providing project knowledge-transfer presentation sessions

Azure SQL Database team• Collaborated with the Azure Cloud SQL Data team to identify tests to be written and worked in their design • Implemented functional tests, unit tests and end-to-end tests to ensure high-quality for Azure SQL databases using C# • Took ownership of the management workflows to enable the migrations (both forward and reverse migration: from/to General Purpose to/from Hyperscale) between different Azure SQL service tiers for databases across the world ranging from the order of megabytes to terabytes • Created a reporting/monitoring system for migration tests and drove the resolution when regressions emerged • Mitigated worldwide incidents in on-call team to ensure availability of production Azure SQL databases to customers • Wrote root cause analysis (post-mortem) for worldwide incidents and identified fix items to prevent them (used: Kusto)

Worked in the Data division (Big Data)• Performed DevOps deployment automation of a Business Intelligence (BI) platform to clusters residing in a Cloud platform using Chef• Collaborated with different teams to complete the automation to make the BI platform available to any user within the company• Developed a test framework using Apache Oozie and Python for the automatic monitoring of the BI platform’s services• Extended the functionality of a Hive to Relational Database (RDB) data transfer tool by adding features using Java• Wrote Hive queries and developed Python scripts to compare the HDFS data query results with the RDB’s data definition• Created the continuous integration and continuous deployment (CICD) aspect of multiple projects using Jenkins• Generated dashboards for metrics and data visualization (analytics and monitoring) for multiple projects• Developed a MapReduce job to make the processing of data (order of hundreds of gigabytes) more efficient by replacing a Spark job while taking advantage of Hive bucketing and the Parquet storage format• Wrote a Spark job for data post-processing while selecting ORC as output format (tens of gigabytes) for better efficiency

• Created a chatbot with Python to parse and process user input queries and generate an appropriate response• Determined and utilized NLTK and WordNet, along with a database containing API data as training corpus, to perform tasks such as part-of-speech tagging and named-entity recognition• Designed a UI for the chatbot consisting of a website utilizing HTML, CSS, JavaScript, jQuery, Bootstrap• Constructed a RESTful JSON web service employing Flask to expose the functionality of the chatbot through an API which is consumed by the UI via AJAX calls• Collaborated with the PaaS Dev team to determine features to build such as word completion and spell correction

• The summer camp taught around 400 school students and involved the programming languages Scratch, Python and Java• Provided lectures about programming concepts and managed a class size of 30 students (each week)• Implemented solutions for Python and Scratch lab exercises to serve as reference for teaching assistants

• Built the structure for a supermarket’s online shopping website (considering the features to be offered and accessed by different types of users e.g. the customer, the delivery person, the administrator) using Python and Django• Developed the front-end of the website utilizing web technologies (HTML5, JavaScript, CSS, Django, Bootstrap, jQuery)• Utilized Django templates to create web pages which followed a hierarchy through inheritance
