## What I'm looking for

```text
I'm looking to build and modernize backend services where I can own delivery from requirements and architecture through implementation, review, and production support, especially in integration-heavy systems.
```

## About

```text
I've delivered six government digital-services projects at N3.Tech, evolving from legacy support to designing and building three services from scratch. Two of those services were completed and accepted by the customer.

I modernized distributed Django/DRF HR platforms, supporting migrations from Python 2.7 and Django 1.8 while delivering personnel, training, staffing, approval, signature, and government-integration functionality.

I built an on-premises OCR/LLM document-recognition service, a PostGIS-backed document-approval system, a file-storage service, and a Kafka/Debezium CDC synchronization service. My work spans FastAPI, Django, PostgreSQL, asynchronous processing, CI/CD, PDF generation, electronic signatures, and production support.

Earlier, I led backend delivery for ARTW's Strana real-estate platform and built Django/DRF systems and integrations at Creonit. I also bring hands-on Linux systems and network administration experience, and I enjoy turning unclear requirements into workable architecture, estimates, and delivered services.
```
