Project History
Voice Verify Biometric Solution
A voice-based biometric authentication solution for call centers and as a Python back-end developer and tech lead of a team of three, I was tasked with creating the MVP from the PoC.
The project aimed to integrate an existing voice verification software with OpenSIPS PBX and create a Django-based RESTful API for storage, enrollment of voice samples, and integration with customers' back office software. I was also responsible for DevOps and designing deliverable images with VirtualBox for end-user deployment.

Oxbridge Admissions
Oxbridge Admissions is an app that aims to bring justice to admissions in Oxford and Cambridge and I built this Django REST framework application to replace the legacy one in Perl. I took control of the overall architecture, developed the back end myself, and deployed both the back end and the front end.
Django-GDPR Open-source Library
https://github.com/druids/django-GDPRI was solely responsible for analyzing, architecting, and developing an open-source Django library to handle GDPR data consent, anonymization, and pseudonymization. As the customer used Django rollback to retain changes to the database, anonymization was focused on that. For some data, such as birth dates, the app anonymizes the data so that the customer can still use it for statistical purposes. The library also allows for pseudonymization, and users can revert the data to its original form by providing a user-specific key, such as an email.
Pulp Project
https://pulpproject.org/A Django-based software for Python, Ansible, Docker, and RPM package distribution used by Red Hat to provide software to customers. I was one of the developers responsible for overhauling the codebase to Python 3 and presenting new features to the public community.
CRM and Event Managment Platform for Turistic Information Center
I designed, developed, and implemented a comprehensive information system for TIC BRNO, primarily managing the Brno Christmas Markets, which annually attract over 1 million in-person visitors, and other events. Building it from scratch using Django, I managed both front and back end, covering all aspects from architecture to full implementation.
Key features included robust event and booth management, customizable workflows automating document forwarding (invoices to accounting), and automatic contract generation from templates. I engineered a sophisticated vehicle permit handling system with approval processes and developed a dynamic notification system for rejections, pending approvals, and critical updates.
The system also provided versatile contact management with detailed filtering and exporting. I implemented invoice import and CSV data export. A specialized Gourmet Brno competition module automated certificate generation. For administrators, I integrated a timeline for deadline management and alerts, ensuring seamless data integration with automated company profile creation via IČO and intelligent form submission integration.
