About me

Who I am

Applied Mathematics student at DNU focused on async Python backends, scraping/OSINT systems, and production-shaped services with FastAPI, Redis, PostgreSQL/MongoDB, and Docker. I build public portfolio systems that demonstrate Clean Architecture, resilient workers, and real ops tooling.

  • Async Python: FastAPI, aiohttp, Playwright, SQLAlchemy 2.0
  • Data & OSINT pipelines with Redis queues, DLQ, and Docker Compose
  • Open to Junior / Strong Junior Python backend roles

About this page

A Steam-inspired personal portfolio highlighting three production-oriented Python systems: scraping/OSINT collection, FastAPI analytics, and an open-data security pipeline.

Projects

Featured Systems

Three public repositories built as interview-ready backend demos — not toy To-Do apps. Each one ships with Docker Compose and a clear architecture story.

OSINT / Scraping ShadowCrawl Async public-source collector with dual-path fetching (aiohttp + Playwright), Redis queues, and MongoDB storage.
Python 3.12 Playwright Redis MongoDB Docker
FastAPI / Analytics VacancyPulse API REST API with Clean Architecture for vacancy search, filtering, and Redis-cached market analytics.
FastAPI SQLAlchemy 2.0 PostgreSQL Redis Docker
Pipeline / Security OpenSignal Pipeline Open-data workers with retry/DLQ handling and HTTP/TLS security fingerprint enrichment.
Async Workers Redis Queue PostgreSQL TLS/HTTP FP Docker
