I'm Django developer with 15yr+ experience and previously running an agency mainly focused on ecommerce development on top of Python 3 and Django, VueJS, ReactJS and currently consulting the clients solo focused on the complex and high-load Django projects, data pipelines, ETL, microservices, Docker etc. I worked with the projects in the various industries, such as ecommerce, fintech, regtech, sales, marketing, ticketing, hospitality, e-learning, services booking etc and took different roles on the projects, both as the contributor and as the technical/team leader. During the last few years my main focus was consulting and contributing to the distributed and high-load Python/Django/Docker projects as well as their maintenance and scaling. Apart from work on the commercial projects, I also contributed to various open-sources projects, such as: Django, Django-allauth, Django REST Framework and others, wrote articles about the Django development. Currently I'm building the core of my Python-powered books recommendation platform - data models and pipelines, AI models, ML- and DevOps. I also used to visit Python conferences and gave a few talks on the Python and Django topics: • PyBerlin 2020 - Python 2 to 3 migration • DjangoCon Europe 2020 - There's more than one way to draw a map • PyCon.DE 2018 - Developing Ecommerce Platform With Django Oscar • DjangoCon Europe 2017 - How to keep open-source project alive.

I build production backend systems in Python and Go, ship full-stack apps with the MERN stack, and integrate AI features that actually work in production, not just demos. 6+ years across Django, FastAPI, Node, and React running on AWS and Kubernetes, currently leading a 15-engineer team. Most clients come to me for one of these: Backend & APIs — REST and microservice APIs in FastAPI, Django, and Go, built to scale and not fall over under load. Database design, caching, background jobs, the full picture. Full-stack MERN — end-to-end apps with React, Node, Express, and MongoDB, from database to UI, shipped and maintained. AI/LLM features — RAG pipelines, LLM-powered assistants, document processing, and AI tooling integrated into real products. I focus on making these reliable and cost-effective, not just wiring up an API call. Integrations & data — connecting messy third-party systems (SOAP/REST, ETL pipelines, Snowflake) so data actually flows where it needs to. Recent highlight: I built an AI-powered auditing engine on an ETL/Snowflake pipeline that surfaced $40M+ in missed commissions for a client. If you need a backend that holds up, a full-stack app shipped end to end, or AI features that work, send me a message with what you're building and I'll tell you honestly whether I'm the right fit.
