Project started as native ad network, with ppc model and had huge problem with fraud clicks.

Anti-fraud was a priority, combining browser fingerprinting techinuques i was able to solve this

problem, it did require developing own web analytics platform, which i did using nodejs +

mongodb

At this point management decided that working with sites on individual approach is ineffective

and it's time to work on rtb protocol with Yandex and Google, so we started integration with

multiple SSP's, first small like Republer and Otm and then with Google and Yandex

We collected all user data that you can imagine, this led to over 300 TB in one month, raw data

was storend in mongodb and important metrics in clickhouse.

During project development it has undergone many changes, a lot of my work was R&D, finding

new ways to stay competitive on advertising market, lowering click price and finding new ways

to understanding users and they needs.

Project was made with small team (due to budgeting issues) we started with full dev

department (6 people) and some outsource members and then we quickly downsized (not by

my decision) to 3 people ( Devops, ml engineer and me ), but still we managed to make good

work in this complex circumstances.

System was designed to withhold 45k rps, but we didn quite get there, maximum was 18k rps.

JetStat ( private link - This is advanced reports system, basic idea that you have your

import blocks, manipulation blocks and export blocks. You collect data from multiple

sources(google analitycs, excel, csv, ect.), manipulate it (join, union, etc.), and export it

somewhere. Made with vuejs, service workers, svg, MongoDB

I was Head Dev of this project, my part was to workshop architecture and select technologies,

assemble a team. At the beginning was only i and internal customer. I started with laravel and

unit tests, after that were front end part where vuejs become very handy. Project was full of

complicated manipulations places because of data size (gb of information), most heavy places

of logic for back was done in python. For me his project was very interesting because of amount

of data and untyped structure of it. Basically it was GUI for database.

were provided by friendly web designer. Mail and server setup were a big part of the project. As a

server I used vps with centos 7 and PHP fpm 7.1. Mail was new for me, but I manage to make it

in best practises with dkim and dmark, as result mail was accepted by everybody

Also were where many small jobs and personal projects, all that is not really interesting or can

be examples of work.
