Work experience

Analyst

from 07.2020 to 02.2022 (1 year 7 months)
Zakupka.com, Миколаїв (Retail)

Since I was the only analyst in the online e-commerce marketplace company, my role can be described as a general type Analyst - I performed different types of tasks that are usually performed by a Product, Data, Marketing, and Web Analysts.


A brief description of some projects that I performed:


1. Successful implementation and improvement of the Descriptive and Diagnostic type of analytics in the company (almost from scratch).


2. Active promotion and increasing the proportion of evidence-based and data-driven decision-making and reducing the proportion of decision-making based on HiPPO gut feeling and fast opinion.


3. Effective implementation of descriptive/inference statistics and systematic analytical approach in the everyday working process.


4. And here are examples of some of the large series of tasks:

1) building and improving the A/B testing processes (almost from scratch);

2) implementation of the CPA payment model (accent on mathematical and statistical part);

3) search and study areas with low values in behavioral ranking factors;

4) study of the relationship between the number of sales managers' calls and their productivity;

5) creation of an algorithm for detecting an abnormal price in a product category;

6) creation of a system for assessing the degree of stabilization of the metric value;

7) creation of a working prototype of a content-based recommendation system (similar products).



Achievements (some of them):

a) increase in the volume of Google mobile organic traffic by at least +20%;

b) a significant improvement in bounce rate, exit rate, average time on page, and depth of view;

c) an increase in the conversion of the "Buy" button in the products list (Mobile) by at least +30%;

d) the study of the strength of the influence of a group of variables in the auction formula on key indicators helped to improve the CTR by at least +5%;

e) relatively quick detecting and clarification of anomalies in data (some of them were critical bugs after an update or fix), the negative impact of which could cause reputational damage and/or decrease the number of users and/or cost many tens of thousands of dollars.



Additionally (A/B):

1) conversion of the "Buy" button in the product card (Mobile) was increased by at least +10%;

2) team efforts managed to achieve an increase in the conversion rate for viewing information about the seller in the product card (Desktop) by at least 15% while reducing the number of user complaints to support by about 2 times;

3) was avoided the implementation of an experimental variant that could worsen key metrics by at least 20-30%;

4) the creation and implementation of an advanced Tracker of ideas and A/B tests helped to reduce the delay between the end of the previous test and the beginning of the next test by at least 3 times and in general highly increased the quality of the testing process.
