Specialization: Backend developer, DevOps, Tech-lead

It is very important for me what impact the developed product has on people. I believe that with the help of knowledge and technology we can make the world a better place. For this, I'm constantly learning and developing as a specialist. My primary technology stack for the last 5 years is React/JavaScript, Django/Python, Postgres and DevOps practice. Also, I work with aiohttp, FastAPI, Scrapy, Celery, Git, Docker, DevOps CI/CD (GitLab, CircleCI), PyCharm, psql, ElasticSearch, Redis, AWS services. At one point, I focused on the following languages: Delphi, Python (+Qt, Django), C#, PHP (Yii), PL/SQL, Perl, JavaScript (jQuery, React/Redux), XSLT, HTML/CSS, Java, MySQL, Oracle. For general development, I did pet projects in these languages: C++, Assembler, Prolog, QPILE, J2ME, Ruby, Erlang. I help organize conferences in the local community Krasnodar Dev Days. Also, I teach the course "Linux administrate" in the local university.

Work experience

Senior Backend Developer

since 01.2021 - Till the present day |PandaDoc

Python (sync/async), microservices, kafka, k8s

At this place of work, I was engaged in the development of new integrations. I made 2 integrations: for Zoom and Slack, which allowed me to attract new customers and increase conversion. Moreover, I was involved in architectural issues and as a result significantly reduced the complexity of the code, simplifying further development. Although it wasn't part of my job, I helped with product research, production issues, did educational webinars, and spoke at conferences on behalf of the company.

Backend developer / data analyst

03.2019 - 02.2021 |Anagram

Python, PostgreSQL, Celery, Redis, RabbitMQ, Docker, PHI, HIPAA

In this position, I help people to chargeback reimbursement by their insurance. I worked on the backend side - Python (include async), PostgreSQL, Celery, Redis, RabbitMQ, Docker, PHI, HIPAA. My responsibility is scraper service and eligibility benefit validation. It was a mission-critical service for the entire organization, so it was covered in tests and metrics. Issue management and emergency recovery plans were also developed. As a team member, I'm actively involved in discussions, sharing knowledge, and improving processes. Also, I was interested in DevOps (I increased the speed of CI/CD pipeline from 28m to 8m).
