I'm a final‑year Electronics & IT student from Niš, focused on low‑level C/C++, embedded systems (RP2040 / Raspberry Pi / FreeRTOS), and security/exploit development. I build end‑to‑end projects—from firmware and real‑time pipelines to Android/Angular frontends and cloud backends. My goal: to advance in red teaming, AI-driven security research, and exploit development by combining low-level systems expertise with offensive security innovation.

• 🔭 Now: polishing C++ multithreading, RTOS on microcontrollers,mqtt and safe exploitation basics.
• 🎯 Next: internship‑level readiness , and AI/ML and neural networks.
• 🧪 Lab: Raspberry Pi security camera + Android push pipeline, Pico + SPI camera(work in progress), face recognition tools,mqtt led contol app.
• 🐧 OS: Arch / Manjaro / Kali /Ubuntu •

Quick snapshots. Pin these repos on your profile for visibility.

Repo: alarmSecuritySystem

• Raspberry Pi captures motion → uploads image → Firebase push → Android app shows notification + image.
• Includes Python scripts, server bits, and Kotlin/Compose client app.
• Goals: reliable notifications, clean README with architecture diagram, and real hardware demo.

Repo: projekatZI

• C++ crypto modules (e.g., Tiger/XXTEA variants), utilities, and CLI demos.
• Great place to showcase secure implementations and unit tests.

Repo HeapMemory

• Implementation of a custom heap memory manager in C/C++.
• Focus: allocators, fragmentation handling, memory safety, debugging leaks/overflows.
• Demonstrates low-level systems skills and practical debugging techniques.

Repo MemeoryExploit

• Progressively implemented 6 exploit techniques from scratch on 32-bit Linux: stack buffer overflow, ret2libc (DEP bypass), ASLR bypass, stack canary bypass, RELRO bypass, and full ROP chain construction.
• Built all payloads without exploit frameworks — manual offset calculation, gadget discovery, and GOT/PLT manipulation.
• Achieved full mitigation coverage: DEP, ASLR, Stack Canary, and RELRO all bypassed and documented.

• Embedded: RP2040 (Pico/Pico W), SPI/I²C/UART, camera FIFO handling, dual‑core patterns.
• Real‑time: FreeRTOS tasks, IRQ vs polling trade‑offs, scheduling camera capture + transfer.
• GPU: CUDA basics.
• Security: exploit‑dev fundamentals (ASLR/PIE, ROP), and safe research.
• Data: Neo4j (graph relationships), Redis (realtime messaging/notifications), MongoDB (flexible documents).
• Mobile/Web: Android (Kotlin/Compose), Angular frontends, Nestjs backend, Nodejs backend.
• Memory: Heap memory management, custom allocators, debugging leaks/overflows.

• Start with clear specs, then iterate quickly with small, testable steps.
• Prefer typed, deterministic code and profiled hot paths.
• Document setups so others can reproduce results.

• Open an issue in any repo, or ping me on LinkedIn.
• I’m happy to collaborate on embedded, or security‑oriented projects.
