Work history

04/14–Present – Freelance/Learning Python and frameworks/in search of first job.
∘ Studying Python and infrastructure.
 ∘ Deep diving into Linux (Debian) + DevOps. I've rejected the Namecheap hosting (DNS only
for now) and the website infrastructure will be deployed on a Raspberry Pi 4B (IoT device).
∘ Creation of a public website (semyon72.com). It is implemented using Django and contains
public and administrative parts. Several utilities have also been created for bulk conversion
of Libreoffice files to HTML, comparing them with the database and checking the site's
links on external and internal resources (tools that automate the completeness of the site).
∘ Own pet projects and test tasks. All of them published on GitHub and recent ones are
pointed below.
∘ Creation of websites (Wordpress) on own hosting (starting with GreenGeeks, then
Namecheap) and their further support.
∘ Writing individual pages and utilities, bug-fixing.
∘ Learning the Symfony framework and related libraries.
∘ Several own projects mainly in the area related to IoT (Some projects are published on
GitHub)

09/12-01/14 – Projestic, Kharkiv (outsource), PHP developer (LAMP full stack).
∘ Support the websites of several regular clients.
∘ Adding new features and pages, bug-fixing or changing existing pages.
∘ One-time jobs (possibly for other clients).
∘ Writing clients to work with external API services.
∘ Parsing csv, tsv, xls files and so on.

11/1999-01/2012 - Department of Information Technology and Customs Statistics at Kharkiv
Customs, from Database support specialist, DBA to software developer/engineer with DevOps
and network management elements.
∘ Development of systems for accumulating information for the needs of customs, including
analytical reports and general statistics.
∘ Maintenance of hardware in proper state.
∘ Development, design and deployment of an wide distributed communication network
(Intranet) to collect information from and between remote offices.
∘ Direct participation in the development and formation of all stages of transmission,
processing, accumulation, analysis of data, generation of reports (analytical reports),
programming and automation of processes.
∘ Database supporting.

Last 3 projects/test tasks
https://github.com/semyon72/scrap.test.task – Test task on automating data scanning from Web
pages (scraping) and putting them into the PostgreSQL database. Scanning takes place
automatically in according to the schedule rules. Table data backup and export to CSV are also
performed according to the rules (rules are independent). Deployment is done both manually
(instructions in Ukrainian on GitHub) and using Dockerfile and Docker-compose. Configuration is
implemented with using an external .env file. A logging system has been implemented too.

Tech-stack: requests, lxml, beautifulsoup4, SQLAlchemy, psycopg, python-dotenv, marshmallow,
environs, schedule, PostgreSQL.

https://github.com/semyon72/cv – This project is my vision of how curriculum vitae (CV or
Resume) should look to help the organizations and those who are looking for a job to find each
other with best matching. This vision is the thoughts of developer/engineer how it can be
implemented to be maximum helpful for consumer to automate matching, maximize the number of
representations of the final view. All code based on next two main frameworks - Django and Django
REST framework. More details in description on GitHub.

Tech-stack: Django, Django REST framework, Pillow, Beautyfulsoup4, lxml, requests, reportlab,
drf_spectacular, SQLite, unit and integration testing

https://github.com/semyon72/maklai-internship – Test task. The main goal was to create a single
REST API endpoint that should implement the generation, based on the input syntactic tree of the
English text, of all possible options for permuting parts of the text without changing the overall
meaning (paraphrasing). For example, there is a phrase 'The charming Gothic Quarter, or Barri
Gòtic, has narrow medieval streets filled with trendy bars, clubs and Catalan restaurants' one of
the options for rearranging parts of a sentence without changing the general meaning is 'The
charming Gothic Quarter, or Barri Gòtic, has narrow medieval streets filled with clubs, trendy bars
and Catalan restaurants'. The endpoint had to accept this tree (specific format) and return all
possible options in the same format.

Tech-stack: Django, Django REST framework, NLTK, unit and integration testing
