Привет!
Я Роман Спиридонов
Software Engineer / Backend Developer Python / Golang

Python • Golang • FastAPI • Flask • Django • AIOHTTP •JavaScript • Vue.JS • SQL • PostgreSQL • Docker • CI/CD • Git • ORM • Linux

To understand the algorithm, you need to see it.

Open to interesting offers for Software Engineer (Python, Golang) and Back-end Developer (Python, Golang) positions, in a professional team working on interesting projects and using modern practices and technologies in my work. I like a healthy iterative software development process consisting of modern decomposition, refactoring, software design and object responsibility sharing practices.

Python is my favourite language, python one love. I like go (and I have experience bringing services into production in it). I feel good about rust, strict typing, type theory in general, FP elements and monads to the best of my shallow understanding.

My specialty is Software Engineer / Back-end Developer. I work in information technology sphere for more than 5 years. Commercial development experience in Python for over 5 years, in Golang just under a year.
My account on GitHub (https://github.com/Speccy-Rom)
Also on Linkedin my full career path is posted as well.

During my time in commercial development at companies and freelance outsourcing projects I’ve gained practical experience, learned many peculiarities of the language:

Python —>
Good knowledge of current trends and nuances of python
Good understanding of python infrastructure and distinguish pypy, mypy, pyenv, pipenv, cython, cpython, cythonize, pypa, pypi from each other 🙂
FastAPI, Pydantic, Alembic, Sqlalchemy ORM/ Sqlalchemy Core —> my usual stack;
Aiohttp, Flask, Django, and the main battery, Masonite, Asyncio, Sanic;
Celery, RQ;
Threading, Multiprocessing, Subprocess (all sorts of supervisors, CLI, CI/CD and other scenarios) I prefer cooperative multitasking, asyncio better than threading !
Typing, including protocols and other interesting new stuff
PyTest, Faker, Hypothesis;
Pipenv, Poetry;
Fabric;
MyPy, Flake8 Pylint, Black, Isort;
Typer
Comments in the code should answer the question — «Why» and the code should answer the question — «How».

Golang —> it’s a relatively new but promising language to me
Some experience
Some experience in developing system and infrastructure microservices
Know &&understand —> goroutines, context-switches, generic, atomic,
I have great interest in it, I’m planning to learn and use it in production
OTHER TECHNOLOGIES: —>

Clean Architecture: —>
I use design patterns, SOLID principles, GRASP templates, REST API, MVC/MTV, KISS, DRY, YASGI patterns.

System design: —> Must have (Martin Kleppmann — Designing Data-Intensive Applications)

Pursuing system design skills
Studying design practices for distributed systems and high-load systems
MQ: —> Love to use in microservices architecture

Kafka / Kafka Streams
RabbitMQ (consumer, producer, queue, exchange, etc.)
NATS
Databases: —> MySQL, PostgreSQL, MariaDB, ClickHouse, MongoDB,
Elastic Search
ACID, CAP
Transactions
Explain analyze
Complex queries
Profiling
Replication (row, statement, mixed, master-slave, master-master, sync, async)
Indexes (Btree, Hash, Gin, Gist, Brin)
Triggers
Migration to 4-byte Unicode and other quirks of mysql life.
SQL (RAW), Tortoise ORM, Peewe
Redis: —> cache or message broker.
Usually I prepare cache in Redis. The cache speeds up query processing but does not affect fault tolerance.

UNIX (Linux): —>
Experienced in UNIX (macOS, Linux). Have experience in developing bash-scripts.

Ci/Cd: —>
Used Git / GitLab CI and cloud storage when developing projects in the team.
Have experience with Nomad orchestrator and its integration with Gitlab Ci
in conjunction with Consul and Consul-Template (a system to support service discovery and distributed key-value storage). Using Github Actions.

Docker: —>
Working with Docker, Docker-Compose at advanced user level. Writing DockerFile / DockerFile BuildKit for different build stages to deploy and deliver application to dev/stage/prod loops.

Keycloak: —>
Working with Keycloak, used in projects for authentication and authorization.

Processes: —>
Working on Agile (Scrum) and traditional development methodologies.
I like to document development of services and software in Jira / Confluence.
In Jira I start releases, create sprints, can set up epics and can move tasks around the dashboard;
Can develop services on my own, but I am also a team player in all senses;
A lot of experience working remotely, no self-discipline problems. No supervisor required as I consider myself responsible and attentive to detail especially in development
Training: —>
I use edabit, hangarbank, leetcode, problem-solving training services
Learning English. Definitely need more practice
I have a desire to develop in Golang, Rust.
I’m fond of SPIDCUBING on the level of small-scale contests.
Beside that, I like youtube, netflix, like to drive fast and work hard. I remember the days of ZX Spectrum) and its ecosystem.
