Portfolio
Map Matching Algorithm Analysis | [GitHub]

Developed an implementation of Map Matching algorithms utilizing Hidden Markov Models
(HMM) and the Viterbi algorithm.
Conducted a thorough comparative analysis of the implemented solution against OSRM (Open
Source Routing Machine).
Documented the algorithmic logic and code implementation as part of a Master's thesis.

Visio Configurator

Developed the backend logic and architecture for a specialized visual configuration tool.
Engineered the underlying data models and API endpoints for dynamic component
configuration. (Note: Project successfully developed but currently paused prior to production
deployment).

Payment System | [GitHub]

Backend system built with Spring Framework and PostgreSQL, implementing RESTful APIs for
payment processing and account management.
Key features include robust payment status tracking, account sorting algorithms, and
administrative controls for user management.

Web Novel Reader API | [GitHub]

Comprehensive REST API platform serving as the backend core for a reader application.
Built to experiment with and implement advanced design patterns, efficient data handling, and
modern backend architectures.
