Hello! I am a final-year student at the Faculty of Technical Sciences (FTN).
While I'm wrapping up my degree, I spend my time diving deep into backend architecture, mobile development, and system design. I love solving problems where logic meets creativity.




My Technical Toolbox








Selected Works

A collection of systems I engineered from scratch to understand how things work.

System & Tech What makes it cool?
Rabbit Social Core
Java Spring Sockets
Instead of using Nginx, I wrote my own Load Balancer and Message Queue in Java to handle high concurrency. It features custom rate-limiting and dual-mode messaging.
Wanderlust Core
Go Microservices gRPC
A deep dive into distributed consistency. I implemented the SAGA Orchestration pattern to manage transactions across Postgres, Mongo, and Neo4j.
Travel Tales
.NET Angular PostGIS
Large-scale tourism platform built using Domain-Driven Design (DDD). Developed by a cross-functional team of 16 engineers, featuring AI integration and gamification.
QuestLog Native
Android SQLite Sensors
Not just a to-do list. It's an Offline-First RPG engine that uses the phone's accelerometer (shake events) for combat logic. Syncs seamlessly with Firebase.
Sentinel PKI
Java Cryptography Security
A military-grade security simulation. Features a Zero-Knowledge credential vault and implements complex X.509 certification paths using BouncyCastle.
Manufacturing Core
Oracle SQL Modeling
A real-world ERP module for a family business. It models complex BOM (Bill of Materials) structures and replaced a manual paper-based system.
