• Developed Riskengne project based on C++17. Riskengne is a real-time client portfolio calculation (for example: Black-Scholes https://www.investopedia.com/terms/b/blackscholes.asp ) project based on market data from multiple exchanges (deribit, okex, binance…) written in C++. As a result, I ported the previous kdb+/q solution to C++ solution and reduced costs for X-Margin• Successfully migrated a part of logic and architecture from Kx Stream to TorQ in docker. As a result, we have reduced the number of issues and speeded up the release procedure• Got a new experience with cryptocurrencies• Market data (rdb/hdb): technical support, backfill, bugfix, tuning. As a result, we had a stable database based on kdb+/q.• Developed Concept of Monitoring solution for project based on TorQ (Prometheus, Grafana, Node Exporter and...). As a result, I released monitoring for Kx Stream and for TorQ solutions • Implemented QA approach with full UI automation (Selenium + Selenoid + framework written in Python). As a result, we got more stable builds.

• Code migration from DB to BNP Paribas, as a result we successfully migrated our codebase• Implemented new logic for rollover, as a result I speeded up rollover more than 2-3 times• new metrics for Market data, as a result we • New stacks

● Developed new market data stacks/assets (tp, rdb, pdb, hdb, hstats, gw…) based on kdb+/q, Java languages and our internal framework● Had deals with architecture design and security checks, for example:- Protection from harmful users queries (I used .z.pg and .z.ph )- acl checks- developed pstats (periodic stats)The result is a more stable database and flexible architecture● Developed such features such as: chain tp, real time stats across the stack/assets, calculating historical prices and other static data,● Developed authentication dll for Q Insight Pad. As a result, compliance issues have been resolved for all persons working with kdb+/q.● Developed lot of automation scripts and as a result I simplified my daily routine● Solved some interesting tasks such as: performance issues, rollover issues, data issues …(for example: wrong schema)● SL3 support, bug fixing

● I brought a new unique approach for testing all projects in the bank based on kdb+ / q language ● I implemented Autotest Framework based on kdb+/q and java script languages● Prepared a fully automated QA environment with more than 400 q and java processes ● Prepared presentations, QA documents, knowledge base ● Big data experience

● Developed new strategy for IT department (Git + Jira + Confluence + Agile + regular autotests)● Developed automation framework (Selenium 2.x + TestNG + Jenkins)● Prepared a knowledge base based on Android 2.x-4.x● Hiring new persons

● Managed a team of 18 employees● Trainings for QC engineers● Developed new strategy of automation for QC department.● Research new technologies

● Automated test scenarios using Test Complete, vbs, C# and Java script.● Leadership roles in creation and execution of QA and testing processes, test strategies and plans, and bug documentation and regression.

● Test plans test cases.● Regression testing, smoke testing, stress testing, performance testing, function testing, usability testing, exploratory testing...
