SUMMARY
Self-taught programmer with 5+ years of experience in software development, cybersecurity, and reverse engineering . Expertise in C++, Python, Ruby,
database design, and full-stack web development (front-end & back-end). Passionate about building secure, high-performance systems and solving
complex technical challenges. Committed to continuous learning and applying cutting-edge solutions to drive innovation

EXPERIENCE
Python "BOT Developer"
Freelance November 2023 - Present
• Designed and deployed Telegram bots in Python using "python-telegram-bot", "aiogram", and "Telegram Bot API" for tasks as customer
engagement, notifications, and workflow automation.
• Integrated external APIs (REST, Webhooks) to fetch real-time data (e.g., weather, payments, social media) and process responses dynamically within
bots.
• Built database-driven bots with SQL (SQLite3/MariaDB/PostgreSQL) to store user preferences, transaction history, and analytics, ensuring efficient
data retrieval and scalability.
• Automated business processes (e.g., order tracking, form submissions, content moderation) via bots for reducing manual effort.
• Managed version control with Git (GitHub/GitLab) to maintain clean, modular code and collaborate with clients on feature updates.

overloading.
• Memory Management - Pointers, references, and dynamic memory allocation (new, delete). Smart pointers for modern C++.
• Standard Template Library (STL) - Containers (vector, map, set), algorithms, and iterators.
• Multithreading & Concurrency - Thread management, mutexes, and race conditions. Async programming and futures.
• Debugging & Tools - Using debuggers, static analyzers, and IDEs. CMake for project builds.
Reverse-Engineering, IDA (Junior)
S.E. • Sydney, Canada • 2019
• Introduction to Reverse Engineering -Core Concepts: Static vs. dynamic analysis, disassembly vs. decompilation. Toolchain Overview: IDA Pro vs.
Ghidra vs. Binary Ninja. Common Use Cases: Malware analysis, vulnerability research, legacy code analysis.
• IDA Pro Interface & Basic Workflow - Navigating Views: Graph mode, text mode, hex view. Basic Navigation: Jump to address, cross-references
(XREFs), function lists. Customizing Layouts: Saving and loading database files.
• Static Analysis Fundamentals - Disassembly Basics: Understanding x86/x64/ARM assembly in IDA. Function Analysis, library calls, and control flow.
Naming Conventions: Renaming variables/functions (N key), adding comments. Data Structures: Defining arrays, structs, and enums.
.NETworking, pockets, and security (WireShark)
S.E. • Sydney, Canada • 2019
