Work experience
All
Since January 2023 Self Employed Kyiv
Developed:
1) Stock market prediction software tailored to Indonesian stocks.
Software scrapes a lot of market information from different sources
(including Twitter API to analyse positive and negative news on each
market), then engineers some important features of the data and
provides recommendations for buy/sell strategies based on the DL
model output;
2) Telegram bots:
• (Personal project) An encryption bot that embeds Unicode symbols
into some picture's bytes. Used for entertainment as well as for
decryption complexity study. Romantic and scary, depending on what
you chose;
• Developed a bot that uses NLP to monitor channel subscriptions and
re-post "valuable" news to a private channel;
3) Personal websites:
• (Personal project) Created an "Every second matters" timers app
where you can set stopwatches and get notified on some events;
• (Personal project) Created a web application to demonstrate and
promote 5 little kittens that we barely managed to save from the
sickness. Succeeded to find them new homes in mere weeks;
• Interactive web CVs for people that want to shine in a way or two;
4) Socket-level application to analyse and somewhat abuse network
usage and connectivity.
Delivered:
1) Personal lessons on Python, Web Development, Statistics and Data
Analysis. Achieved high satisfaction rate and imposing results: have
been able to develop solid juniors from a group of fitness trainers.
Work experience
Data Analyst, Training Organization Manager
From March 2022 to December 2022 Kyiv School of Economics Kyiv
1) Conducted covid and tuberculosis spread analysis:
• Analysed outbreak relations between Ukraine and bordering
countries;
• Forecasted spread, mortality and hospitals load using a bunch of
methods: Facebook Prophet, LSTMs, ARIMA;
• Communicated results with the policy makers of the Ministry of
Health.
2) Took part in the USAID-PATH-KSE project, aimed to teach top-notch
MOH executives better ways of analysing statistical and
epidemiological data, share our insights into the data etc. Performed a
lecturer's, manager's and analyst's duties at the same time:
• Devised and implemented two complete streams of lectures: Python
Essentials and Statistical Analysis;
• Created a complete study plan, coordinated it with foreign lecturers
from Cyprus and Spain, as well as Ukrainian ones. Managed to achieve
astonishing preparedness in a drastically short time period;
• Found, tested and worked in tight collaboration with realtime
interpreters to make lessons graspable for the audience;
• Delivered "Statistical Analysis" lectures set. Received decent amount of
positive responses regarding great on-classes interactivity, achieved
due to a pletora of case studies (content) and great inter- personal
relations (soft skills).
• Managed to improve the overall course satisfaction from "around
5/10" to "around 8/10".

Work experience
Development Team Lead
From September 2021 to March 2022 Kyiv School of Economics Kyiv
Headed the implementation of a complex data analytics system used
to control vaccination provision and allocation based on multiple
factors. We joked at times that we've built our own PowerBI. The system
had the next requirements:
• Restricted Access. The app should have had a centralised admittance
policy (users were registered by a very few people);
• Allow for complex vaccine allocation policies. One example: some
vaccines were supplied in a "not quite fresh" condition. Software must
had been aware of such a scenario and react accordingly: allow for a
few days to distribute, then consider this exact vaccine as "in usage
right now", and finally provide calculations based on that.
• Be general enough to encompass new datasets and "playstyles".
Hence, be a complete data analysis platform;
• Have solid optimization. Be fast and not overweighted by the datasets
and the overall computational complexity. This way it gained an
advantage over Google Spreadsheet alternatives.
• Lots of other fun.
Work experience
Data Analyst
From April 2021 to October 2021 Kyiv School of Economics Kyiv
1) Developed sustainable data analysis products and software:
• Developed ETL pipelines for the Ministry of Health of Ukraine's realtime
COVID data. Implemented data-preshaping, data error detection, data
cleaning, complex error detection scenarios (like a sudden complete
change of data semantics in a particular column);
• Implemented, supported and gradually deployed a centralised
database approach to corporation's internal data keeping (in place of
the existing Excel file ownership based on who conducts the research)
with sophisticated security distribution policies;
• Created PowerBI dashboards based on the previously mentioned
data;
• Created a GCP server to keep the data, handle event hooks like "data
source update", communicate with PowerBI to initiate updates, create
backups.
2) Participated in a "COVID-19 emergency handling team", having a
direct communication with Ministry of Health of Ukraine:
• Proposed, implemented and analysed COVID observation and
containment routines to withhold the infection inside a "hospitals
capability", as well as measures of success for those;
• Implemented modelling curves for COVID spread, mortality etc. Used
SIR, ARIMA, SARIMA as well as LSTM Deep Learning models to find the
best fitting one;
• Implemented attractive and interactive data representations (using
HTML, CSS, JS) that could be shown to general public in order to
achieve trust and confidence;
• Was constantly communicating the results to make impact on the
nation-wide decisions made
by policy makers. Participated in crafting press and public
communications to promote vaccination awareness and support
among the general public based on statistically achieved results.
