Expert in Python development, great knowledge in the ecosystem and internals of the language allow me to serve as a great source of knowledge and mentoring for my clients. I took part in projects helping build anything from highly performant financial backends, trading algorithms, e-commerce applications, API backends, data workflows, console and embedded applications, machine learning solutions, server management scripts.

I have helped my clients bootstrap their ideas off the ground with backends created in Django. Experience in DevOps allow me to start with a solid and secure infrastructure on day one, building on top of that performant and scalable APIs that now power large applications of my satisfied customers.

Built a large scale scraping solution with scrapy, BeautifulSoup, asyncIO, Airflow, Python, Django, Docker. The software would index thousands of products and schedule them for updating periodically. Additional indexers would look for new and deleted products, only image metadata was pulled to minimize bandwidth, everything done so that the cost of scraping would be minimal, additional AWS/Scaleway instances would be spawned whenever system had to process large chunks of data at once.

Helped my clients getting their ideas off the ground in express time with React Native. That involved building a series of mobile apps used to gather product information for on-site agents who would scan GTIN and product description in stores. Other project involved building an app providing product recommendations having user's preferences and history gathered with simple and crisp UI.
